大约5%的新兵在高强度的体能训练中发生应力性骨折，主要发生在下肢。我们在美国海军学院的一个夏季训练项目中比较了患有应力性骨折损伤的年轻男性和女性（受试者）与匹配的未受伤志愿者（对照组），以确定应力性骨折损伤的可能危险因素。受试者组由13名女性和18名男性一年级学生组成，他们通过平片和/或核素骨扫描证实了训练诱导的应力性骨折损伤。对照组由13名女性和18名男性组成，他们在plebe夏季训练期间没有受伤，但与31名受伤的plebes进行初始力量测试（1英里跑步时间，平均值：女性，7.9分钟;男性，6.4分钟）和身体质量指数（平均值：女性，23.4;男性，23.8）。我们发现，受试者在第1天和诊断应力性骨折的日期（平均值，第35天）之间体重显著减轻（平均值，2.63 +/- 0.54 kg），并且他们继续减轻体重，直到DEXA扫描日期（平均值，第49天）。在女性新生中，没有证据表明女性运动员三联征（饮食失调、月经失调或骨密度低）。女性受试者的大腿围明显小于女性对照组，男性受试者的大腿围有低于男性对照组的趋势。男性受试者的全身骨矿物质含量显著低于男性对照组。两组间胫骨远端和股骨颈的骨密度无显著差异。受试者和对照组之间的DEX衍生结构几何特性没有差异。因为平均而言，男性受试者的胫骨显著长于男性对照，所以男性受试者的平均骨强度指数显著低于男性对照。我们的结论是，在年轻的新兵中，显著的，急性的体重减轻加上定期的日常体育训练可能是年轻军人应力性骨折损伤的一个重要的危险因素。(C)2004年爱思唯尔公司All rights reserved.
Approximately 5% of all military recruits incur stress fracture injuries during intense physical training, predominately in the lower extremity. We compared young men and women with stress fracture injury (subjects) to a matched group of uninjured volunteers (controls) during a summer training program at the United States Naval Academy to identify possible risk factors for stress fracture injury. The subject group was composed of 13 female and 18 male plebes with training-induced stress fracture injury verified by plain radiographs and/or nuclear bone scan. The control group was composed of 13 female and 18 male plebes who remained without injury during plebe summer training but who were matched with the 31 injured plebes for the Initial Strength Test (1-mi run time, means: women, 7.9 min; men, 6.4 min) and body mass index (means: women, 23.4; men, 23.8). We found that the subjects lost significant body weight (mean, 2.63 +/- 0.54 kg) between Day I and the date of their diagnosis of a stress fracture (mean, Day 35) and that they continued to lose weight until the date of their DEXA scan (mean, Day 49). Among female plebes, there was no evidence of the female athlete triad (eating disorders, menstrual dysfunction, or low bone density). Thigh girth was significantly smaller in female subjects than in female controls and trended to be lower in male subjects than in male controls. Total body bone mineral content was significantly lower in the male subjects than in male controls. Bone mineral density of the distal tibia and femoral neck were not significantly different between the groups. DEXA-derived structural geometric properties were not different between subjects and controls. Because, on average, tibias were significantly longer in male subjects than in male controls, the mean bone strength index in male subjects was significantly lower than that of male controls. We conclude that significant, acute weight loss combined with regular daily physical training among young military recruits may be a significant contributing risk factor for stress fracture injuries in young military men and women.
