A Study on the Body Composition and Symmetry of Female Young Trainees during Military Basic Physical Training
This paper aims to study the changes in body composition and symmetry of female young trainees during military basic physical training,and provide a basis for daily training.Methods:Using literature review,experimental methods,and mathematical statistics,25 healthy female subjects were subjected to military basic physical fitness for a period of 4 months,and body composition testing was performed using a dual energy X-ray bone density meter.Results:(1)The bone area,bone mineral content,and bone density of the right arm were significantly higherthan those of the left arm(P<0.05);(2)But the fat content andpercentage inthe right arm were significantly lower than those in the left arm(P>0.05);(3)The muscle content and overall weight of the right arm were significantly higher than those of the left arm(P<0.01).(4)There was no significant difference in bone area,bone mineral content,bone density,fat content,muscle content,and fat percentage between the left and right lower limbs(P>0.05).(5)In terms of the distribution of overall Z-score,2 to-1 accounts for 64%,-1 to-2 accounts for 28%,and<-2 accounts for 8%.Conclusion:During the basic physical training period,there are differences in the upper limb components among female students,while there are no differences in the lower limb components.Overall,the symmetry is good,but the overall Z-score is at medium and high risk,indicating a low availability of energy.It is suggested to fully optimize training and nutrition programs to maintain and improve bone health.
