The Influence of Prolonged Military Physical Fitness Training on Body Composition and Bone Density in Young Male Cadets
OBJECTIVE:This study aims to explore the effects of prolonged military physical fitness training on the body composition and bone density of young male cadets,providing a foundation for everyday training practices.METHODS:Twenty-one cadets undergoing short-term training were selected as the control group,while 33 cadets undergoing long-term training were chosen as the experimental group.Dual-energy X-ray absorptiometry was employed for body composition analysis.RESULTS:The experimental group exhibited significantly lower overall fat mass,total body fat percentage,and obesity index/body weight compared to the control group(P＜0.05).However,no significant differences were observed in waist-hip ratio,trunk fat ratio/leg fat ratio,and trunk/limb fat mass ratio(P＞0.05).There were no significant differences in overall lean mass,lean index,left upper/lower limb lean mass ratio(％),and right upper/lower limb lean mass ratio(％)(P＞0.05).Overall bone density and age-matched Z-scores showed no significant differences(P＞0.05).CONCLUSION:Prolonged physical fitness training can significantly reduce fat but has limited impact on bone density.Training programs should include osteogenic exercises to promote bone health.
