Abstract

Purpose

To identify the risk factors for training-related lower extremity muscle injuries in young males by a non-invasive method of body composition analysis.

Methods

A total of 282 healthy young male volunteers aged 18 – 20 years participated in this cohort study. Injury location, degree, and injury rate were adjusted by a questionnaire based on the overuse injury assessment methods used in epidemiological studies of sports injuries. The occurrence of training injuries is monitored and diagnosed by physicians and treated accordingly. The body composition was measured using the BodyStat QuadScan 4000 multifrequency Bio-impedance system at 5, 50, 100 and 200 kHz to obtain 4 impedance values. The Shapiro-Wilk test was used to check whether the data conformed to a normal distribution. Data of normal distribution were shown as mean ± SD and analyzed by t-test, while those of non-normal distribution were shown as median (Q₁, Q₃) and analyzed by Wilcoxon rank sum test. The receiver operator characteristic curve and logistic regression analysis were performed to investigate risk factors for developing training-related lower extremity injuries and accuracy.

Results

Among the 282 subjects, 78 (27.7%) developed training injuries. Lower extremity training injuries revealed the highest incidence, accounting for 23.4% (66 cases). These patients showed higher percentages of lean body mass (p = 0.001), total body water (TBW, p = 0.006), extracellular water (p = 0.020) and intracellular water (p = 0.010) as well as a larger ratio of basal metabolic rate/total weight (p = 0.006), compared with those without lower extremity muscle injuries. On the contrary, the percentage of body fat (p = 0.001) and body fat mass index (p = 0.002) were lower. Logistic regression analysis showed that TBW percentage > 65.35% (p = 0.050, odds ratio = 3.114) and 3rd space water > 0.95% (p = 0.045, odds ratio = 2.342) were independent risk factors for lower extremity muscle injuries.

Conclusion

TBW percentage and 3rd space water measured with bio-impedance method are potential risk factors for predicting the incidence of lower extremity muscle injuries in young males following training.

总体内水分百分比和第三空间水分是年轻男性在训练中下肢肌肉受伤的新风险因素

方法共有 282 名年龄在 18-20 岁之间的健康年轻男性志愿者参与了这项队列研究。根据运动损伤流行病学研究中使用的过度运动损伤评估方法，通过调查问卷对损伤部位、程度和损伤率进行了调整。训练损伤的发生由医生进行监测和诊断，并采取相应的治疗措施。使用 BodyStat QuadScan 4000 多频生物阻抗系统在 5、50、100 和 200 kHz 下测量身体成分，以获得 4 个阻抗值。采用 Shapiro-Wilk 检验法检测数据是否符合正态分布。正态分布数据以均数±标准差表示，采用 t 检验分析；非正态分布数据以中位数（Q1、Q3）表示，采用 Wilcoxon 秩和检验分析。结果在 282 名受试者中，78 人（27.7%）出现训练损伤。下肢训练损伤的发生率最高，占 23.4%（66 例）。与没有下肢肌肉损伤的受试者相比，这些患者的瘦体重（p = 0.001）、全身水分（TBW，p = 0.006）、细胞外水分（p = 0.020）和细胞内水分（p = 0.010）的百分比更高，基础代谢率/总重量的比率也更大（p = 0.006）。相反，体脂百分比（p = 0.001）和体脂质量指数（p = 0.002）较低。逻辑回归分析表明，TBW 百分比 > 65.35%（p = 0.050，几率比 = 3.114）和第三空间水分 > 0.95%（p = 0.045，几率比 = 2.342）是下肢肌肉损伤的独立危险因素。

期刊介绍： Chinese Journal of Traumatology (CJT, ISSN 1008-1275) was launched in 1998 and is a peer-reviewed English journal authorized by Chinese Association of Trauma, Chinese Medical Association. It is multidisciplinary and designed to provide the most current and relevant information for both the clinical and basic research in the field of traumatic medicine. CJT primarily publishes expert forums, original papers, case reports and so on. Topics cover trauma system and management, surgical procedures, acute care, rehabilitation, post-traumatic complications, translational medicine, traffic medicine and other related areas. The journal especially emphasizes clinical application, technique, surgical video, guideline, recommendations for more effective surgical approaches.
