Reliable data on the impact of physical training on light infantry units in terms of injuries and time loss are sparse. This study evaluated a light infantry unit (n = 181) prospectively and followed it throughout one year of infantry training and operations. Fifty-five percent of the soldiers (n = 101) experienced one or more injuries. Eighty-eight percent of the injuries were training-related conditions, which resulted in 1,103 days of limited duty. Lower extremity overuse injuries were the most common type of injury documented. Fractures accounted for the greatest number of days of limited duty. Risk factors for training-related injuries identified by this study were cigarette smoking, high percentage of body fat, extremely high or low body mass index, low endurance levels, and low muscular endurance levels (sit-ups). Logistic regression showed that cigarette smoking and low endurance levels were independent risk factors for training injuries. These data indicate that the incidence of training-related injuries in infantry units is high. A number of modifiable injury risk factors were identified, suggesting that many of these injuries may be preventable.
关于体能训练对轻步兵部队在受伤情况和时间损失方面影响的可靠数据很少。本研究对一个轻步兵部队（n = 181）进行了前瞻性评估，并在一整年的步兵训练和行动中对其进行跟踪。55%的士兵（n = 101）经历了一次或多次受伤。88%的损伤与训练相关，导致1103天的有限执勤时间。下肢过度使用损伤是记录中最常见的损伤类型。骨折导致的有限执勤天数最多。本研究确定的与训练相关损伤的风险因素包括吸烟、高体脂百分比、极高或极低的体重指数、低耐力水平以及低肌肉耐力水平（仰卧起坐）。逻辑回归显示，吸烟和低耐力水平是训练损伤的独立风险因素。这些数据表明步兵部队中与训练相关损伤的发生率很高。确定了一些可改变的损伤风险因素，这表明其中许多损伤可能是可以预防的。
