Abstract

PURPOSE

To determine whether preseason aerobic capacity is independently associated with in-season injury among collegiate soccer players.

DESIGN

Prospective cohort study.

SETTING

University athletic department.

PARTICIPANTS

Forty-three NCAA Division I soccer athletes (male = 23).

INDEPENDENT VARIABLES

Gender and preseason lean body mass (LBM), body fat percentage (BF%), and maximal aerobic capacity (V[Combining Dot Above]O2max).

MAIN OUTCOME MEASURES

In-season injuries were recorded during the season, and body composition and fitness variables were compared between injured and uninjured players. Multivariate regression models were developed to predict injury during the entire season and during the first 4 weeks of the season.

RESULTS

Thirty-five injuries among 25 players were recorded during the season. Players injured at any point during the season had lower V[Combining Dot Above]O2max (57.7 vs 63.4 mL·kg·min, P = 0.014) and Tmax (15.8 vs 17.2 minutes, P = 0.035), compared with uninjured players, but no differences were noted in age, gender, LBM, or BF%. Players injured during the first 4 weeks of the season had lower LBM (49.7 vs 56.0 kg, P = 0.038) and Tmax (15.1 vs 16.7 minutes, P = 0.043) than uninjured players. For injuries occurring throughout the entire season, V[Combining Dot Above]O2max was an independent predictor of injury (P = 0.043), whereas gender, LBM, and BF% were not. During the first 4 weeks of the season, V[Combining Dot Above]O2max (P = 0.035) and LBM (P = 0.049) were related to injury, whereas gender and BF% were not.

CONCLUSIONS

Aerobic fitness is an independent predictor of in-season injury. Early-season injuries are related to aerobic fitness and LBM.

CLINICAL RELEVANCE

Efforts to increase aerobic capacity and LBM among soccer players in the off-season may help reduce in-season injury.

摘要

目的

确定大学足球运动员季前有氧能力是否与赛季中受伤独立相关。

设计

前瞻性队列研究。

地点

大学体育部门。

参与者

43名美国大学体育协会（NCAA）一级足球运动员（男性23名）。

自变量

性别、季前瘦体重（LBM）、体脂百分比（BF%）和最大有氧能力（V̇O₂max）。

主要观察指标

记录赛季中的受伤情况，并比较受伤球员和未受伤球员的身体成分及体能变量。建立多变量回归模型以预测整个赛季及赛季前4周的受伤情况。

结果

赛季中25名球员共出现35次受伤。与未受伤球员相比，赛季中任何时间受伤的球员V̇O₂max较低（57.7对63.4 mL·kg·min，P = 0.014）且Tmax较低（15.8对17.2分钟，P = 0.035），但年龄、性别、LBM或BF%无差异。赛季前4周内受伤的球员LBM（49.7对56.0 kg，P = 0.038）和Tmax（15.1对16.7分钟，P = 0.043）低于未受伤球员。对于整个赛季发生的受伤情况，V̇O₂max是受伤的独立预测因素（P = 0.043），而性别、LBM和BF%则不是。在赛季的前4周，V̇O₂max（P = 0.035）和LBM（P = 0.049）与受伤有关，而性别和BF%则无关。
