摘要
目的:研究军事基础体能训练期间男性青年学员体成分状况及对称性的变化,为日常训练提供依据.方法:对25名健康男性受试者进行为期4个月军事基础体能,采用双能X射线骨密度仪进行体成分检测.研究结果:右臂骨面积、骨矿含量、和骨密度显著高于左臂(P<0.05);左右臂脂肪含量不存在差异(P>0.05).右臂消瘦质量,整体质量显著高于左臂(P>0.05);右臂肌肉含量和整体质量显著高于左臂(P<0.01).但右臂脂肪百分比显著低于左臂(P<0.01).左右下肢骨面积、骨矿含量、骨密度、脂肪含量、肌肉含量、脂肪百分比不具有显著性差异(P>0.05).整体Z评分的分布2~-1占76.9%%,-1~-2占19.2%,<-2占3.8%.研究结论:基础体能训练期间男性学员上肢体成分肢体间存在差异,下肢体成分肢体不存在差异,整体上对称性较好,但整体Z评分处在中风险和高风险比例较高,提示存在能量可利用性低的情况.应采取有效的应对措施,预防长期不利于骨骼健康的影响.
Abstract
This research delves into the variations in body composition and symmetry among male cadets undergoing four months of basic military physical fitness training,aiming to establish a foundation for daily training.METHOD:Dual-energy X-ray absorptiometry was utilized to assess body composition in 25 healthy male participants during the training period.RESULTS:The right arm exhibited significantly higher bone area,bone mineral content,and bone density compared to the left arm(P<0.05);no significant difference in fat content was observed between the left and right arms(P>0.05).Right arm lean mass and overall mass were notably higher than the left arm(P>0.05);right arm muscle content and overall mass were significantly greater than the left arm(P<0.01).However,the right arm's fat percentage was significantly lower than the left arm(P<0.01).No significant differences were found in the bone area,bone mineral content,bone density,fat content,muscle content,and fat percentage of the lower limbs(P>0.05).The overall Z-score distribution revealed 76.9%within the range of 2 to-1,19.2%within the range of-1 to-2,and 3.8%below-2.CONCLUSION:Throughout basic physical fitness training,male cadets exhibit upper limb body composition discrepancies,while lower limb body composition remains consistent.Despite relatively good overall symmetry,a higher proportion of Z-scores in the moderate and high-risk ranges suggests potential low energy availability.Implementing effective measures is crucial to preventing adverse effects on long-term skeletal health.
