Prognostic potential of body composition indices in detecting risk of musculoskeletal injury in army officer cadet profiles.

OBJECTIVES: High values in most of the body composition indices have been related to musculoskeletal injuries, but limited data exists on the accuracy of these diagnoses when detecting musculoskeletal injuries in military populations. METHODS: The suitability of body fat percentage, body mass index, fat mass index and fat free mass index to identify injury risk was examined in a group of army officer recruits. All body composition diagnoses were measured in 268 male army officer recruits prior to the commencement of basic combat training. Musculoskeletal injury was identified using codes from the International Classification of Diseases. The area under the curve, in the receiver operating characteristic curve, was used to quantify the overall ability to discriminate between those who were injured and those who were not. RESULTS: The statistics indicated that all indices, apart from body mass index, had a significant possibility to detect musculoskeletal injury potential (p < 0.05; 61%-63%). The respective cut-off points used to classify individuals as injured were for body fat percentage >22, for fat mass index >6.5 and for fat free mass index <16.5. CONCLUSION: Body mass index values can not similarly detect the possibility of occurrence of musculoskeletal injuries in army officer recruits, just as other body composition diagnoses related to fat mass or/and free fat mass. However, the cut off-points related to the overall diagnostic performance of each body composition index should be used with caution and in accordance with the aims of each experimental setting.

Profiles of musculoskeletal injuries among Greek Army officer cadets during basic combat training.

OBJECTIVE: Injury prevalence and types of injury were recorded among Greek Army officer cadets during basic combat training (BCT). METHODS: Two hundred thirty-three male recruits from the Hellenic Army Academy were monitored for musculoskeletal injuries during a 7-week BCT period. RESULTS: Sixty-six (28.3%) recruits suffered from some form of injury, leading to 1.22 training days lost per study recruit. More than half of the injuries (51.3%) occurred in the first 2 weeks of the BCT, with ankle/foot strains and sprains being the most common injuries. CONCLUSION: Despite the absence of fractures and the low number of upper extremity injuries during the BCT, injury prevalence was high, with ankle- and foot-related injuries to be responsible for a long period of lost training days. Preventive efforts should focus on addressing the high rate of first-time and recurrent ankle ligament sprains and possible protective equipment to limit their frequency and severity.
