Abstract
INTRODUCTION: There is limited and contrasting evidence on the relationship between maturity and injury in youth sports. Studies of the anthropometric characteristics and biological maturity status as injury risk factors in youth middle- eastern are also limited, highlighting the need for more research to be conducted. The purpose of the present study was to investigate injury according to biological maturity in highly trained youth athletes based at a Middle Eastern Sports Academy METHODS: A total of sixty-seven male athletes (age range: 11-18 years) representing four sport disciplines were enrolled and grouped into 2 sport categories: individual sports (Athletics and fencing) and racquet sports (Squash and Table Tennis). Assessment of risk factors: Athletes’ anthropometric characteristics were assessed using non-invasive methods to calculate age at peak height velocity (APHV) and total years from PHV. Participants predicted mature height (PMH) were collected and categorized into four PMH quartiles. Consenting athletes had wrist and hand radiographs taken for assessment of skeletal age (SA), using Fels method. Early and late maturers were those with a SA of >1 year older or younger than their chronological age (CA), respectively. RESULTS: For the total sample across all sport groups, 43 (64%) athletes had one or more injuries totaling 212 injuries. Injury incidence was 4.9 injuries per registered athlete. Survival analysis using Cox regression of maturity status found that early mature athletes had two-fold higher injury risk over time compared to late maturers HR (2.04, 95%, 1.15-3.61, P=0.015). PMH was associated with injury risk HR (1.05; 95% CI: 1.01-1.08, p=0.006). Compared to participants in the 1st quartile (<176cm) for PMH, athletes in the 4th quartile (≥ 184 cm) have higher (up to 2-fold) injury risk HR (2.41, 95% CI: 1.42 – 4.08, p=0.001). In this study, injury risk in racquet sports was similar to individual sports HR 1.14 (95% CI: 0.86 – 1.52, p= 0.37). CONCLUSION: Early maturity and gradient for PMH were significant predictors of injuries in youth.

There is limited and contrasting evidence on the relationship between maturity and injury in youth
sports. Studies of the anthropometric characteristics and biological maturity status as injury risk factors
in youth middle- eastern are also limited, highlighting the need for more research to be conducted.
The purpose of the present study was to investigate injury according to biological maturity in highly
trained youth athletes based at a Middle Eastern Sports Academy
METHODS:
A total of sixty-seven male athletes (age range: 11-18 years) representing four sport disciplines were
enrolled and grouped into 2 sport categories: individual sports (Athletics and fencing) and racquet sports
(Squash and Table Tennis).
Assessment of risk factors:
Athletes{\textquoteright} anthropometric characteristics were assessed using non-invasive methods to calculate age at
peak height velocity (APHV) and total years from PHV. Participants predicted mature height (PMH) were
collected and categorized into four PMH quartiles. Consenting athletes had wrist and hand radiographs
taken for assessment of skeletal age (SA), using Fels method. Early and late maturers were those with a
SA of {\textrangle}1 year older or younger than their chronological age (CA), respectively.
RESULTS:
For the total sample across all sport groups, 43 (64\%) athletes had one or more injuries totaling 212
injuries. Injury incidence was 4.9 injuries per registered athlete. Survival analysis using Cox regression of
maturity status found that early mature athletes had two-fold higher injury risk over time compared to
late maturers HR (2.04, 95\%, 1.15-3.61, P=0.015). PMH was associated with injury risk HR (1.05; 95\% CI:
1.01-1.08, p=0.006).
Compared to participants in the 1st quartile ({\textlangle}176cm) for PMH, athletes in the 4th quartile (\ensuremath{\geq} 184 cm)
have higher (up to 2-fold) injury risk HR (2.41, 95\% CI: 1.42 -- 4.08, p=0.001).
In this study, injury risk in racquet sports was similar to individual sports HR 1.14 (95\% CI: 0.86 -- 1.52, p=
0.37).
