ABSTRACT

Amateur team sports impose repeated physical and neuromuscular demands on athletes who differ in

age, sex, training history, playing position, competitive level, and exposure. Nevertheless, assessment

in resource
-limited settings is often fragmented, standardized inconsistently, or restricted to isolated
indicators. This scoping review mapped evidence on field
-based anthropometric, functional,
performance, and preparticipation assessment in amateur and non
-elite team-sport populations and
examined how these
domains are associated with physical performance, musculoskeletal injury history,
and preventive decision
-making. The review followed PRISMA-ScR and the Arksey and O’Malley
framework. PubMed/MEDLINE was searched for publications from 2021 to July 2026 usi
ng a title-
anchored strategy restricted to English, Spanish, and Chinese. Of 145 records identified, 119 were

retained after title and abstract screening for full
-text eligibility assessment; therefore, the synthesis
remains provisional until full
-text confirmation is completed. Evidence was organized into three
components: anthropometry and body composition; functional and field performance; and

preparticipation screening, injury epidemiology, and prevention. The emerging evidence indicates that

body mass
index has limited value as a standalone indicator and should be complemented by measures
of central adiposity and body composition. Intermittent endurance, sprinting, change of direction,

explosive performance, mobility, and balance represent related but n
onredundant dimensions whose
associations with body profile vary across sex, age, sport, position, and competitive level. Injury

evidence supports multifactorial interpretation, systematic recording of previous injury, and

multicomponent prevention, while
cautioning against using any single test to predict injury. The review
proposes an integrative framework and a resource
-proportional assessment pathway prioritizing safety,
standardization, measurement error, and contextual interpretation.

Evaluación Física y Funcional en el Terreno de Juego en Deportes de
Equipo Amateur: Antropometría, Rendimiento y Cribado Previo a la
Participación como base para la Prevención de Lesiones y la Orientación
del Entrenamiento. Una Revisión Exploratoria

RESUMEN

Los deportes de equipo amateur imponen demandas físicas y neuromusculares repetidas sobre
deportistas que difieren en edad, sexo, experiencia de entrenamiento, posición de juego, nivel
competitivo y exposición. Sin embargo, la evaluación en contextos con recursos limitados suele
encontrarse fragmentada, estandarizada de manera inconsistente o restringida an indicadores aislados.
Esta revisión de alcance mapeó la evidencia sobre evaluación antropométrica, funcional, del
rendimiento y preparticipativa realizada mediante procedimientos de campo en poblaciones amateur y
no élite de deportes de equipo, y examinó cómo estos dominios se asocian con el rendimiento físico,
los antecedentes de lesión musculoesquelética y la toma de decisiones preventivas. La revisión siguió
PRISMA-ScR y el marco de Arksey y O’Malley. Se realizó una búsqueda en PubMed/MEDLINE de
publicaciones comprendidas entre 2021 y julio de 2026, mediante una estrategia anclada en el título y
restringida an inglés, español y chino. De los 145 registros identificados, 119 fueron retenidos después
del cribado de título y resumen para la evaluación de elegibilidad a texto completo; por tanto, la síntesis
permanece provisional hasta completar dicha confirmación. La evidencia se organizó en tres
componentes: antropometría y composición corporal; evaluación funcional y rendimiento de campo; y
tamizaje preparticipativo, epidemiología de lesiones y prevención. La evidencia emergente indica que
el índice de masa corporal presenta un valor limitado como indicador aislado y debe complementarse
con medidas de adiposidad central y composición corporal. La resistencia intermitente, la velocidad, el
cambio de dirección, el rendimiento explosivo, la movilidad y el equilibrio representan dimensiones
relacionadas, pero no redundantes, cuyas asociaciones con el perfil corporal varían según sexo, edad,
deporte, posición y nivel competitivo. La evidencia sobre lesiones respalda una interpretación
multifactorial, el registro sistemático de lesiones previas y la prevención multicomponente, al tiempo
que desaconseja utilizar una sola prueba para predecir lesiones. La revisión propone un marco
integrador y una ruta de evaluación proporcional a los recursos que prioriza la seguridad, la
estandarización, el error de medición y la interpretación contextual.

INTRODUCTION

Amateur team sport is a regulated competitive practice that, despite its non
-professional status, imposes
real and repeated physical demands on a highly heterogeneous population differing in age, training

experience, playing position, and exposure (Hernand
ez-Martinez et al., 2024). In these settings,
decisions about participation, selection, and training load are frequently grounded in observation and

physical appearance rather than in objective measurement, and structured, systematized assessment

remains r
are (Asimakidis et al., 2024). The gap is not trivial. Amateur athletes sustain musculoskeletal
injuries at rates that are far from negligible (Sonesson et al., 2023), and even lower
-contact modalities
such as flag football report meaningful injury burdens
(Balachandran et al., 2025; Barber Foss et al.,
2023). The scarcity of feasible, reproducible field assessment therefore constrains both the

individualization of training and the early identification of athletes who might benefit from preventive

attention
.
A first obstacle to sound assessment is the widespread reliance on body mass index as a proxy for

physical condition. Body mass index is an accessible mass
-for-stature ratio, but it cannot distinguish fat
mass from fat
-free mass or describe how tissue is distributed, and its conventional cut-off points perform
poorly in athletic populations (Milanese et al., 2025). The body
-composition methods that do capture
these dimensions are not interchangeable, since each carries distinct assumptions, sources of error
, and
dependence on technician standardization (Campa et al., 2021; Kasper et al., 2021). A defensible body

reading in sport is therefore multidimensional, complementing body mass index with indicators of

central adiposity and with estimates of body compos
ition rather than treating a single value as sufficient
(Ben Brahim et al., 2023).

The relationship between body profile and physical performance is, moreover, neither linear nor

uniform. Higher adiposity tends to accompany poorer sprint and change
-of-direction times, whereas
greater fat
-free mass tends to accompany jumping and power output, but the magnitude and even the
direction of these associations vary with age, sex, playing position, and the specific quality assessed

(Bustamante
-Garrido et al., 2024; Ishida et al., 2021; Leão et al., 2022). Evidence in female and semi-
professional
cohorts shows that anthropometric profiles differ by position and sex, which cautions
against adopting a single normative reference (Hernandez
-Martinez et al., 2024; Ramírez-Munera et al.,
pág. 5552
2025; Toro
-Román et al., 2023). These patterns are associated: they describe how body characteristics
and performance co
-vary, not how one produces the other, a distinction that governs the interpretation
offered throughout this review.

Assessment matters not only for describing athletes but also for protecting them. Exercise
-based
neuromuscular and multicomponent programs can reduce non
-contact musculoskeletal injuries in
football and related team sports, yet their benefit depends on ade
quate adherence and, logically, on a
prior diagnostic phase that identifies whom and what to target (Bullock et al., 2025; Lemes et al., 2021;

Mandorino et al., 2023). Body composition and field fitness have, in turn, been combined to model

injury risk in
footballers, an empirical bridge that links the performance axis to the injury axis and
shows that description and prevention are continuous rather than separate concerns (Martins et al.,

2022).

Before any effortful test is administered, a basic preparticipation appraisal of health status, symptoms,

and medical and injury history is warranted. This screening is preventive, proportionate, and explicitly

non
-diagnostic; its purpose is to decide whether to proceed, adapt, postpone, or refer, not to certify
fitness (Weise et al., 2025). Much of the available guidance rests on consensus rather than on trial

evidence, yet the ethical and methodological function of this gate is clear: it is what makes the
remainder
of field assessment defensible (Harmon et al., 2013).

Two formative research protocols motivated the present review, one concerned with anthropometry and

performance in amateur football and the other with preparticipation conditioning, functional evaluation,

and injury history in amateur flag football. Rather
than juxtaposing them, we raise the object of study
to a common level: the system of field
-based physical and functional assessment in amateur team sport,
of which football and flag football are two applications of the same underlying problem,
namely, how
to evaluate an amateur athlete safely, feasibly, and reproducibly in the absence of laboratory resources,

and what such measurements inform. Accordingly, this scoping review asks what recent evidence (2021

to 2026) supports field
-based anthropometric, functional, and preparticipation assessment in amateur
team
-sport athletes, and how these indicators relate to physical performance and to musculoskeletal
injury history and risk.
pág. 5553
Four subquestions structure the synthesis, addressing (a) anthropometry and body composition, (b)

functional and field performance, (c) preparticipation screening and injury, and (d) the integration of

these components and their modulation by sex, sport, a
nd competitive level. The review advances three
contributions: an integrative conceptual framework of field assessment in amateur team sport, presented

in Figure 1; a resource
-proportional field-assessment battery transferable across team modalities; and a
critical synthesis of the direction and heterogeneity of the anthropometry, performance, and injury

relationships, with sex, sport, and level treated as an explicit analytic axis rather than a peripheral caveat.

Figure 1
Integrative Framework for Field-Based Physical and Functional Assessment in Amateur Team Sport
Note
. The framework positions Component III (preparticipation screening and safety) as the entry gate to assessment and,
separately, as the evidence base for injury epidemiology, risk factors, and prevention. Component I (anthropometry and body

composition) and
Component II (functional and field performance) function as descriptors that feed a resource-proportional
field
-assessment battery, which in turn informs two applied aims: training guidance and injury prevention. Sex, sport or
modality, and competitive le
vel operate as cross-cutting modulators (Objective 4). The guiding principle is association rather
than causation, together with standardization and control of measurement error. Own elaboration.

METHOD

Protocol, design, and reporting

This study was designed as a scoping review, an approach suited to mapping a broad and heterogeneous

body of evidence and to clarifying concepts and gaps rather than answering a narrow effect question.

The review was conducted and is reported in accordance
with the Preferred Reporting Items for
Systematic Reviews and Meta
-Analyses extension for Scoping Reviews (PRISMA-ScR; Tricco et al.,
2018
) and was structured following the methodological stages proposed by Arksey and O'Malley (2005)
and refined by Levac
et al. (2010): identifying the review question, identifying relevant records,
selecting sources, charting the data, and collating and summarizing the results. Because most of the

primary studies anticipated in this field are observational, their reporting
was appraised with the
pág. 5554
Strengthening the Reporting of Observational Studies in Epidemiology statement in mind (von Elm et

al., 2007). No meta
-analysis was planned, given the expected heterogeneity of sports, sexes, competitive
levels, and outcomes.

Information sources and search strategy

Records were identified in a single bibliographic database, PubMed/MEDLINE. The use of one

database is an explicit boundary of the review's scope and is acknowledged as a limitation; a fully

exhaustive map would additionally interrogate Scopus, Web of Scie
nce, SPORTDiscus, SciELO, and
Dialnet. The last search was executed on July 15, 2026.

The search used a title
-anchored Boolean strategy composed of three concept blocks combined with the
AND operator: (a) team sport (soccer, football, rugby, futsal, or flag football), (b) competitive level

(amateur, recreational, semi
-professional, sub-elite, university, or collegiate), and (c) the object of
assessment (body composition, anthropometry, injury, or fitness). Anchoring all three blocks in the title

field prioritized precision, so that sport, level, and object of study were simultaneously presen
t in the
record title. The search was restricted by language to English, Spanish, and Chinese, and by publication

date to the period 2021 through 2026. The complete search string, field tags, filters, and eligibility

parameters are reported in Table 1. Ind
ispensable methodological classics outside the temporal window
were admitted when justified, specifically the Yo
-Yo intermittent recovery test protocol (Bangsbo et al.,
2008) and the rating of perceived exertion scale (Borg, 1998).

Eligibility criteria and study selection

Sources were eligible when they met all of the following criteria: a team
-sport population (soccer or
football, flag football, rugby, or futsal) at an amateur, recreational, university, collegiate, semi
-
professional, or sub
-elite level, or a mixed sample including such athletes; assessment of at least one of
the three review components (anthropometry and body composition; functional and field performance;

or preparticipation, injury, and prevention); a primary study, review, or consensus document;

publicati
on in English, Spanish, or Chinese; and publication between 2021 and 2026. Six predefined
exclusion categories were applied: wrong population (E1); topic outside the review axes (E2);

publication type without primary data, such as editorials, study protoco
ls, or errata (E3); wrong
outcome, such as surgical management or diagnostic imaging (E4); non
-retrievable records (E5); and
sport outside the review scope (E6).

Title and abstract screening
were performed autonomously by a large language model applied against
the fixed eligibility rubric described above. This procedure is declared transparently as artificial
-
intelligence
-assisted screening; recent evidence indicates that such models can screen records against
pág. 5556
explicit criteria with useful accuracy, while their performance depends on how precisely the criteria are

formulated and warrants human verification (Khraisha et al., 2024; Oami et al., 2024). Screening was

tuned to favor sensitivity. Intra
-screener stability was estimated by re-adjudicating a reproducible
random subsample of 25 records (seed = 42), blind to the first pass, which yielded 96.0% agreement

(Cohen's kappa = 0.834). Because identification drew on a single database, no duplicate records

required
removal. Of 145 records identified and screened, 26 were excluded (wrong population, n = 1;
outside the review axes, n = 15; publication type, n = 4; wrong outcome, n = 6), leaving 119 sources

provisionally included. Confirmation of these provisionally inc
luded records at the full-text level is
declared as a pending verification step rather than a completed stage. The selection process and the

corresponding counts are shown in Figure 2.

Figure 2
PRISMA-ScR Flow Diagram for Study Selection
Note
. The diagram follows the flow of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension
for Scoping Reviews (Tricco et al., 2018). Identification was limited to a single database (PubMed/MEDLINE), declared as a

scope boundary; the
refore, no duplicate records were removed. Title and abstract screening were artificial-intelligence-assisted
and tuned for sensitivity, with intra
-screener stability of 96.0% (Cohen's kappa = 0.834) on a reproducible random subsample
of 25 records (seed = 42). The 119 sources are provisional inclusions; full
-text confirmation constitutes the pending verification
step. E1 through E4 denote the predefined exclusion reasons applied at screening.

Data charting and synthesis

Data were charted into an evidence matrix capturing, for each source, the author and year, country and

context, study design, sport and sex, sample, variables, instruments, main findings, and limitations

(Table 2). The synthesis was narrative and thematic,
organized by the three review components, with
each component addressing one subquestion.
pág. 5557
Consistent with the scoping design and the heterogeneity of the corpus, no statistical pooling was

undertaken; associations are reported in terms of direction and, where available, magnitude, and are

interpreted as associative rather than causal.

RESULTS

The 119 provisionally included sources were organized into the three review components. Their

provisional characteristics are summarized in Table 2. This section presents the synthesis of Component

I; Components II and III follow. Throughout, relationships
are described as associations, and their
direction and heterogeneity are emphasized rather than any single summary estimate.

Component I. Anthropometry and body composition

This component addresses the first subquestion, concerning what anthropometric and body
-composition
indicators contribute, and what they fail to capture, when describing the amateur team
-sport athlete.
The synthesis moves from the single most common indica
tor to the multidimensional profile that the
evidence supports, and the indicators and methods are summarized in Table 3.
pág. 5560
Body mass index: usefulness and limits in athletic populations

Body mass index remained the most accessible anthropometric indicator in amateur settings, yet the

corpus consistently framed it as a measure of relative mass rather than of adiposity or its distribution.

Analyses in athletes indicated that conventional ov
erweight and obesity cut-off points misclassify
muscular individuals and require revision or external validation before being applied to sporting

populations (Milanese et al., 2025). When body mass index was examined alongside complementary

indices, its as
sociation with fitness was weaker and less specific than that of measures incorporating
stature and fat distribution (Ben Brahim et al., 2023). Longitudinal observation across a competitive

macrocycle further showed that body mass index can remain stable w
hile body composition shifts, so
that a single ratio may conceal meaningful compensatory changes in fat and fat
-free mass (Staśkiewicz
et al., 2022). The evidence therefore supported treating body mass index as a continuous, context
-
dependent descriptor ra
ther than as a classificatory threshold.
Body composition: components and estimation methods

Body composition was most often described through a two
-compartment logic separating fat mass from
fat
-free mass, with the important caveat that fat-free mass is not equivalent to muscle mass. The
reviewed methods, including skinfolds, bioelectrical impeda
nce and vector analysis, and dual-energy
X
-ray absorptiometry, were not interchangeable, since each rest on distinct assumptions and is sensitive
to hydration status, the prediction equation, and technician standardization (Campa et al., 2021). No

single m
ethod emerged as universally superior; the applied literature argued that the appropriate choice
depends on the assessment purpose, the available resources, and the capacity to standardize procedures,

and it reappraised accessible field methods such as ski
nfolds as defensible when performed rigorously
(Kasper et al., 2021). Best
-practice guidance emphasized that body-composition data should be
collected and interpreted
to minimize health and performance risks and to avoid over-interpreting slight
changes
(Mathisen et al., 2023).
Central adiposity: waist circumference and waist
-to-height ratio
Indicators of central adiposity captured a dimension that body mass index does not, namely the

distribution of tissue. Waist circumference and the waist
-to-height ratio were associated with fitness in
young adults in ways not fully reflected by body mass i
ndex alone, which supported their inclusion as
pág. 5561
complementary descriptors (Ben Brahim et al., 2023). In officiating and playing populations,

anthropometric indices differed by competitive division and related to performance, although these

associations were sensitive to the anatomical measurement site a
nd to standardization of the protocol
(İlhan et al., 2023; Samarein et al., 2023). The evidence thus positioned central adiposity as an

informative, low
-cost addition to the field profile rather than as a redundant measure.
ISAK standardization and modulation by sex and playing
position.
Comparability across athletes and studies depended on standardized measurement, and the corpus

repeatedly invoked the procedures of the International Society for the Advancement of

Kinanthropometry as the reference for consistent data collection, including
the derivation of sex-
specific and position
-specific reference values (Petri et al., 2024a). Anthropometry, body composition,
and fitness differed between sexes and playing positions in semi
-professional players, which cautioned
against applying a single
normative profile across roles (Toro-Román et al., 2023). The same logic
extended to flag football, where a proposed kinanthropometric profile for elite athletes offered a body

reference that helps contextualize the modality and bridges the anthropometric
component to the
performance and injury axes (Talavera
-Hernández et al., 2025). Because these profiles varied
systematically with sex, sport, and position, they are read here as modulated associations rather than

fixed standards, a point developed visually
in Figure 3 and revisited in the Discussion.

Figure 3
Conceptual Model of Relationships Among Body Profile, Field Performance, and Injury in
Amateur Team Sport

Note
. The model depicts associative, bidirectional relationships among the three assessment components; it does not posit a
linear causal chain. Neuromuscular control is represented as a mediating pathway linking body profile, performance, and

injury. Double
-headed arrows denote reciprocal association, not causal direction. Sex, sport and modality, playing position,
competitive level, exposure, and previous injury history operate as cross
-cutting modulators (Objective 4). Own elaboration.
Functional and field performance

This component addresses the second subquestion, concerning which functional and field
-performance
tests are valid, feasible, and safe in the amateur setting, and how they relate to the body profile. The

synthesis proceeds from the logic of battery selecti
on to each performance quality and closes with the
notion of performance as a multidimensional profile; the tests, their outcomes, and their standardization

requirements are summarized in Table 4.

Selecting the battery: validity, reliability, feasibility, and non
-redundancy.
Survey evidence on applied testing practice indicated that the choice of tests is driven as much by

feasibility, available time, the competitive calendar, and resources as by measurement properties, and

that the measurement error attached to each test is s
eldom addressed explicitly in practice (Asimakidis
et al., 2024). A systematic appraisal of aerobic
-fitness and repeated-sprint protocols documented
substantial variability in how ostensibly similar tests are administered, which limits comparability

across
studies and settings and underscores the need for explicit standardization of warm-up,
familiarization, number of trials, recovery, test order, timing method, and surface (Asimakidis et al.,

2025).
pág. 5564
Intermittent endurance

Because team play is intermittent rather than continuous, field tests that reproduce repeated high
-
intensity efforts were favored, with the Yo
-Yo intermittent recovery test as the reference instrument
(Bangsbo et al., 2008). A structured compendium of Yo
-Yo results confirmed the test's usefulness while
cautioning that reference values vary markedly by version, sex, age, and competitive level, so that the

distance covered is best treated as a direct field outcome rather than converted into an estimate of

max
imal oxygen uptake (Schmitz et al., 2018). Performance on the test was also shown to improve with
repeated administrations, which makes familiarization a prerequisite for valid interpretation (Zemková

& Pacholek, 2023). Intermittent endurance co
-varied with body composition and with strength and
power characteristics in collegiate and youth players, although the associations were of moderate and

variable magnitude (Ishida et al., 2021; Leão et al., 2022).

Linear speed and change
-of-direction speed
The corpus distinguished acceleration, maximal velocity, the ability to repeat sprints, and change
-of-
direction speed, and it insisted on the conceptual separation between preplanned change of direction

and reactive agility, which involve different percept
ual and coordinative demands (Ciocca et al., 2022;
Morral
-Yepes et al., 2023). Sprint performance was associated with anthropometric and mechanical
factors, and these associations differed by distance, reflecting the distinct contributions of the

accelerat
ion and maximal-velocity phases (Bustamante-Garrido et al., 2024). Lower-body power, body
composition, speed, and agility were interrelated in youth players, but no single measure accounted for

the others, which supports assessing speed and change of direc
tion as related yet non-redundant
qualities (França et al., 2024).

Lower
-limb explosive strength
Vertical and horizontal jumps served as accessible field indicators of lower
-limb explosive strength
rather than as pure measures of mechanical power. Jump performance was associated with fat
-free mass
and with relative strength, and it varied with playing
role and developmental stage, so that it is most
informative as one element of a broader profile (Becerra
-Patiño et al., 2025; França et al., 2024; Ishida
et al., 2021; Leão et al., 2022).
pág. 5565
Mobility, balance, neuromuscular control, and movement quality

Beyond the classic performance qualities, the corpus extended the battery toward the functional and

preventive domain, incorporating mobility, static and dynamic balance, neuromuscular control, and

movement quality, which are particularly relevant in modal
ities that involve acceleration, deceleration,
and pivoting. A randomized controlled trial in university students showed that a functional training

program improved movement quality and physical fitness, indicating that these qualities are both

assessable
and modifiable (Li et al., 2025). Postural control differed across collision, contact, and non-
contact sport athletes, which suggests that balance and control profiles are shaped by the demands of

the modality (Schleich, 2017). Strength and biomechanical c
haracteristics were, in turn, linked to knee-
loading patterns in female footballers, connecting neuromuscular assessment to the injury component

treated in Section 3.3 (Collings et al., 2022).

Internal load and perceived exertion

Ratings of perceived exertion were used as a complement to internal
-load monitoring rather than as a
substitute for test outcomes, and their interpretation was treated cautiously, since perceived effort

reflects but does not replace the objective result of
a performance test (Borg, 1998).
Performance as a multidimensional profile

Taken together, the evidence indicated that no isolated test represents performance. Fitness profiles

derived through principal component analysis differed by playing role in youth players, which

discourages ranking athletes on any single measure and favor
s role- and stage-specific interpretation
(Becerra
-Patiño et al., 2025). The heterogeneity of test protocols documented across the literature
reinforces the same conclusion, since comparisons are only meaningful when administration is

standardized (Asimaki
dis et al., 2025). The direction of these performance associations, and their
integration with the body profile and the injury component, are represented in Figure 3.

Preparticipation, safety, injury, and prevention

This component addresses the third subquestion, concerning how amateur team
-sport athletes are
screened before assessment, what is known about their musculoskeletal injuries, and how prevention
pág. 5568
connects back to the descriptive components. The synthesis moves from the safety gate to injury

epidemiology, then to associated factors, and finally to prevention.

Preparticipation screening and safety criteria

The reviewed guidance framed preparticipation screening as a preventive, non
-diagnostic process
whose purpose is to identify conditions that warrant proceeding, adapting, postponing, or referring,

rather than to certify fitness or guarantee the absence of
risk (Weise et al., 2025). Screening typically
combined personal and family medical history, current symptoms, and injury history, and it relied

heavily on consensus recommendations, including criteria for not initiating a test, interrupting an

ongoing tes
t, and referring the athlete to an appropriate professional (Harmon et al., 2013; Weise et al.,
2025). These stages, decisions, and referral criteria are organized in Table 5.

Epidemiology of musculoskeletal injuries in amateur team sport.

Descriptive evidence indicated that reduced
-contact modalities are not injury-free. In flag football,
reported injuries involved the hand and fingers, knee, and ankle, and included sprains, strains, and

fractures, which supports surveillance of both the up
per and lower extremities despite the modality's
rules (Balachandran et al., 2025; Barber Foss et al., 2023). Injury patterns in female American football

varied by age group, and the differences in contact exposure, rules, and equipment caution against

tra
nsferring those findings directly to flag football (Mao et al., 2025). In soccer and rugby, amateur
cohorts documented meaningful injury occurrence, with sex
-disaggregated patterns in rugby and
prospective injury occurrence in amateur soccer (Prieto
-González et al., 2021; Sonesson et al., 2023;
pág. 5571
Yeomans et al., 2021). Additional rugby evidence characterized incidence, severity, mechanism, and

anatomical distribution, described temporal trends by sex, and mapped the gaps in women's rugby,

where epidemiological data remain comparatively scarce (Bell
ingan et al., 2025; Marrese et al., 2025;
Yendluri et al., 2024). A notable gap across the corpus is the limited adult amateur and Latin American

epidemiological evidence, especially for flag football, a point summarized in Table 6.

Intrinsic, biomechanical, and body
-related associated factors
The literature examined factors associated with non
-contact lower-limb injury, including strength,
biomechanics, inter
-limb asymmetries, neuromuscular control, and previous injury, and it increasingly
framed these within multifactorial rather than single
-factor models. Non-contact anterior cruciate
ligament injury in women served as a paradigmatic case, with syntheses and prospective work

identifying candidate strength and biomechanical indicators and recurring injury mechanisms, while

cautioning that such
indicators are not validated individual predictors (Achenbach et al., 2024; Chia et
al., 2022; Collings et al., 2022; Mancino et al., 2024). Reviews of women's football reinforced sex
-
specific considerations for injury and prevention (John et al., 2025), a
nd a structural equation model of
male footballers represented intrinsic characteristics as interdependent rather than isolated predictors,

which supports a systems
-oriented reading and cautions against single-test decisions (Liveris et al.,
2025). Consist
ent with the screening evidence, previous injury and higher age were prospectively
associated with subsequent injury in amateur players (Sonesson et al., 2023), and body
-composition
and fitness variables have been combined within multivariable injury
-prediction models, an approach
that bridges the descriptive components to the injury component while requiring independent validation

(Martins et al., 2022).

These associated factors are compiled in Table 6, and their bidirectional, non
-causal relationship with
body profile and performance is represented in Figure 3.

Note. ACL = anterior cruciate ligament; MSK = musculoskeletal; M = men; W = women; SR = systematic review. The term

risk factor is reserved for longitudinal evidence in which an exposure precedes and predicts the injury; cross
-sectional,
biomechanical, and
model-derived variables are described more cautiously as associated factors, candidate indicators, or
injury
-related characteristics. Improvements in strength, balance, movement quality, or neuromuscular control are not
interpreted as reductions in injury
incidence unless actual injuries were measured over a defined exposure period. The evidence
base is concentrated in soccer and rugby, includes a substantial proportion of female and youth populations, and offers

comparatively limited epidemiological evide
nce for adult amateur flag football; this asymmetry is treated as a central finding
and a limitation of transferability. Preventive programs should be interpreted in relation to content, exposure, adherence,

implementation of
fidelity, and injury definition.
pág. 5574
Prevention programs and risk perception

Intervention evidence indicated that exercise
-based neuromuscular and multicomponent programs are
associated with reduced non
-contact musculoskeletal injury when they are adequately delivered and
adhered to (Lemes et al., 2021), and consensus
-oriented syntheses for the female athlete emphasized
sex
-informed, multicomponent prevention and the decisive role of implementation fidelity (Bullock et
al., 2025). Multicomponent programs were likewise associated with reduced injury in adolescent team
-
sport participa
nts when dosage and adherence were sufficient (Liu et al., 2026), and sensorimotor and
knee
-focused training modified neuromuscular indicators, although surrogate improvements should not
be equated with reduced injury incidence unless injuries and exposure
were measured (Jaskulski et al.,
2025).

Pragmatic implementation frameworks addressed how such programs are adopted and sustained in real

settings (Patterson et al., 2022), and functional training improved modifiable movement
-quality and
fitness qualities that prevention programs target (Li et a
l., 2025). Because adherence depends on
athletes' beliefs and engagement, risk perception emerged as a relevant implementation outcome rather

than a measure of injury susceptibility (Cardoso
-Marinho et al., 2022). Taken together with the
epidemiological sy
nthesis (Mandorino et al., 2023), these findings close the analytic loop: prevention
presupposes a prior diagnostic phase, so that Components I and II are the descriptive basis on which

Component III acts, an articulation represented in the integrative fra
mework (Figure 1).
DISCUSSION

Integrating the three components: a resource
-proportional framework.
The central result of this review is not a list of indicators but an articulation among them.

Preparticipation screening, anthropometry, and functional performance behaved not as independent

checklists but as an ordered system, in which screening operates
as the entry gate that authorizes
assessment, while anthropometry and functional performance act as descriptors that feed a resource
-
proportional field
-assessment battery serving two applied aims, training guidance and injury prevention.
Read this way, the
body profile is informative only when interpreted purposefully and ethically rather
than as a verdict about an athlete's diet or worth, a stance that the applied literature on body composition

makes explicit (Mathisen et al., 2023).
pág. 5575
Nutrition enters the framework as a transversal dimension of body status rather than as a separate axis

of judgment, consistent with expert guidance on football nutrition and with descriptive work relating

nutritional status to performance in players (Coll
ins et al., 2021; Oukheda et al., 2024). The empirical
practice of combining body
-composition and fitness variables within multivariable injury-risk models
illustrates the same integration in miniature, since it links the descriptive components to the inju
ry
component while still requiring independent validation (Martins et al., 2022). This articulation is

represented in the integrative framework shown in Figure 1.

A proposed field
-assessment battery for amateur team sport
The second contribution is a minimum viable, resource
-proportional battery. The reviewed evidence on
test selection and standardization supports a battery organized by an explicit administration order, in

which neuromuscular, jump, speed, and change
-of-direction tests precede fatiguing repeated-sprint and
intermittent
-endurance tests, and in which familiarization, standardized instructions, invalidation
criteria, and safety rules are specified in advance (Asimakidis et al., 2024, 2025; Bangsbo et al., 2008)
.
The battery is transferable across team modalities and is organized in three resource tiers, essential,

standard, and enhanced, so that a team can assess meaningfully with minimal equipment and scale up

only when resources and standardization capacity allo
w. Crucially, the highest tier is not automatically
superior; the battery must match the assessment question and the setting, and it must remain subordinate

to the safety gate described in the preparticipation evidence (Weise et al., 2025). This decision l
ogic
consolidates the tests and safety criteria compiled in Tables 4 and 5 and is presented as an algorithm in

Figure 4
.
pág. 5576
Figure 4
Decision Algorithm for Selecting and Administering a Resource-Proportional Field-
Assessment Battery in Amateur Team Sport

Note. The algorithm proceeds from the assessment purpose through a preparticipation safety gate to the selection of a resourc
e-
proportional battery organized in three tiers (essential, standard, and enhanced), followed by a standardized test
-administration
sequence, quality control, and an integrated profile that informs purpose
-driven outputs. Tier 3 is not automatically superior;
the battery must match the assessment question and the available resources. Association is not interpreted as causation, and
no
single test predicts injury. Own elaboration, informed by the evidence synthesized in Tables 3 to 5.

Heterogeneity by sex, sport, and level as the interpretive axis

The third contribution is analytic rather than instrumental: the corpus is markedly asymmetric,
and
asymmetric
structures interpretation. The performance evidence was predominantly male and soccer-
based, whereas the injury evidence was predominantly female and concentrated in soccer and rugby,

and the epidemiological evidence for flag football was incipient and la
rgely from the United States
(Bellingan et al., 2025; Hernandez
-Martinez et al., 2024; Ramírez-Munera et al., 2025; Toro-Román et
al., 2023). This
distribution means that a profile or a risk pattern established in one population cannot
be assumed to hold in another, and that reference values and injury priorities should be interpreted, and

reported, with stratification by sex, sport, and competitive
level (Balachandran et al., 2025; John et al.,
2025; Mao et al., 2025). Treating these modulators as a central axis, rather than as a closing caveat, is

what protects the review's conclusions from over
-generalization, and the modulated, bidirectional
char
acter of the relationships among the components is represented in Figure 3 and summarized in the
source characteristics of Table 2.
pág. 5577
Association versus causation and the quality of the evidence

Two cautions temper every inference drawn here. First, the reviewed primary evidence was

predominantly cross
-sectional and observational, which supports statements about how variables co-
vary but not about how one produces another; establishing that an exp
osure precedes and predicts an
injury requires prospective designs with adequate exposure follow
-up, and pooled or model-derived
associations should not be read as modality
-specific individual risk (Chia et al., 2022; Mandorino et al.,
2023; von Elm et al.
, 2007). The under-reporting of measurement error across applied testing further
limits how confidently
slight differences can be interpreted (Asimakidis et al., 2024). Second, the
method of this review imposes its own limits: identification was restricted to a single database, and title

and abstract screening was artificial
-intelligence-assisted and tuned for sensitivity, with full-text
confirmation still pending. These procedures are defensible and transparent, and recent evidence

supports the assisted sc
reening of records against explicit criteria, but they warrant the same interpretive
prudence the review applies to its sources (Khraisha et al., 2024; Oami et al., 2024).

Applied and educational implications

For practitioners in amateur, university, and semi
-professional settings, the framework and battery offer
a feasible path from observation to measurement without laboratory resources,
if data are collected and
communicated confidentially and without stigmatizing language (Kasper et al., 2021; Mathisen et al.,

2023). The preparticipation gate provides a proportionate, non
-diagnostic basis for deciding whether to
proceed, adapt, postpone, o
r refer, and it clarifies when a finding exceeds the assessor's scope and
warrants referral (Weise et al., 2025). Because the effectiveness of any preventive program
depends on
adherence, and adherence depends on athletes' beliefs and engagement, the educational task of building

accurate risk perception is inseparable from the technical task of assessment (Cardoso
-Marinho et al.,
2022). In this sense, the review's applied val
ue lies less in any single test than in a coherent, safety-first,
resource
-aware way of assessing amateur team-sport athletes.
Limitations

Several limitations qualify the scope and the conclusions of this review. First, the heterogeneity of the

corpus, spanning different sports, sexes, competitive levels, instruments, and outcomes, precluded any

statistical pooling, so the synthesis is descri
ptive and maps the direction and breadth of the evidence
pág. 5578
rather than a summary effect. Second, identification was restricted to a single bibliographic database,

PubMed/MEDLINE; although the title
-anchored strategy favored precision, this choice introduces a
coverage boundary, and a fully exhaustive map would add
itionally interrogate Scopus, Web of Science,
SPORTDiscus, SciELO, and Dialnet. Third, title and abstract screening was performed autonomously

with a large language model tuned for sensitivity, and full
-text confirmation of the provisionally
included sourc
es remains a pending verification step; while recent evidence supports artificial-
intelligence
-assisted screening against explicit criteria, this procedure warrants human verification
before the corpus is considered final (Khraisha et al., 2024; Oami et al
., 2024).
Fourth, the evidence base is markedly asymmetric, with performance data concentrated in male soccer,

injury data concentrated in female soccer and rugby, and only incipient, largely United States

epidemiological evidence for adult amateur flag football, wh
ich limits transferability to Latin American
and other underrepresented populations (Balachandran et al., 2025; Barber Foss et al., 2023; Bellingan

et al., 2025). Fifth, the language restriction to English, Spanish, and Chinese, together with variable

acce
ss to full texts, may have introduced language and availability bias. Sixth, most primary evidence
was cross
-sectional and observational, so the associations reported here cannot establish causation, and
the proposed field
-assessment battery, although grounded in the reviewed evidence, has not yet been
validated
.
CONCLUSIONS

This scoping review mapped recent evidence on field
-based anthropometric, functional, and
preparticipation assessment in amateur team
-sport athletes and examined how these indicators relate to
physical performance and to musculoskeletal injury history and
risk. In response to the review question,
the evidence supports assessing the amateur athlete through three articulated components rather than

isolated measurements: a preparticipation safety gate, a multidimensional body profile in which body

mass index i
s a limited indicator requiring complementary measures of central adiposity and body
composition, and a field battery of intermittent endurance, speed, change of direction, and explosive

strength interpreted alongside mobility, balance, and neuromuscular c
ontrol. Addressing the
subquestions, the relationships among body profile, performance, and injury were consistently
pág. 5579
associative, non
-linear, and bidirectional, and they were strongly modulated by sex, sport, and
competitive level.

The review's contribution is threefold: an integrative framework that orders these components (Figure

1), a resource
-proportional and transferable field-assessment battery presented as a decision algorithm
(Figure 4), and a critical synthesis that foregrou
nds the heterogeneity and direction of the evidence
rather than a single estimate. These conclusions are offered with deliberate causal prudence: no single

test predicts injury, and description precedes prevention. Accordingly, the research agenda that fol
lows
is clear. Future work should prioritize prospective designs with adequate exposure follow
-up, stratified
by sex, sport, and competitive level, that report measurement error explicitly, complete full
-text
verification of the provisional corpus, and val
idate the proposed battery locally, including in Mexican
and broader Latin American amateur populations, where the evidence remains scarcest.
