An analysis of characteristics and classification of relative indices of physical compositions and physiological functions of excellent teenage boxers
By measuring 15 indices of physical compositions and physiological functions of 11 ages 15～17 boxers from 5 nationalities,and by performing the test of significance of difference between the said indices and 5 indices of physical compositions 4 indices of physiological functions (±s) of athletes who were at the same age,trained for soccer,middle and long distance race and shooting events in the same sports school,and consisting of multiple nationalities,the authors revealed the following findings: The boxers were characterized with better developed muscles,a heavier body weight as per the same height and physique,and a higher fat content as per the same height and load;in terms of indices of physiological functions,they had absolutely higher vital capacity,and a relatively lower ratio of vital capacity to body weight(but the difference has no meaning of significance);it was shown that the physical constitution of teenage boxers were prone to strength type and strength stamina type.The author also analyzed the classification of 7 derivative indices of physical compositions and physiological functions,and revealed the following findings: Obvious type characteristics and a certain intrinsic linkage existed in between relative indices in weight ratio category,height/weight category,and respiratory function category.
