Characterization Study Of Male Sprinters' Anaerobic Metabolism Ability

Energy metabolism, which is fundamental to maitain human activities and ensure the exercise, is the core issue of Human Movement Science. Currently there are lots of studies of aerobic exercise, but few ones of the anaerobic exercise, especially of sprint's energy metabolism which is still blank. In view of this, the paper aims to explore characteristics of sprinters' anaerobic metabolism and the related factors to provide a guide for the scientific selection and exercise training through anylising male sprinters ' energy metabolism.In this paper, classified statistics and correlation analysis are done mainly by experimentation through the anaerobic power and body composition testing of twenty-two sprinters from Northeast Normal University, Jilin Institute of Physical Education and Jilin ports Team. Conclusions are as follows:1. Male sprinters have a strong anaerobic work capability, and different levels of them show significant differences of anaerobic metabolism capacity; that is, Level 1 athletes have more power ability of Anaerobic work than Level 2 athletes. What is to be noted is that difference between relative maximum power is more prominent than that between the absolute power.2. Level 1 male sprinters will get the limit of their own anaerobic work ability in a shorter time and have a faster decline of speed than those of Level 2.That is, Level 1 male sprinters own better original system phosphate fuel ability which ican be also called acceleration and poorer endurance of relative speed.3. 100M and 200M and 400M athletes show significant project differences of characteristics of anaerobic metabolism, 100M athletes appears to own more excellent ability of the original system phosphate fuel ability while 200M and 400M athletes have greater advantage over power-supply of lactic acid power system.4. Level 1 male sprinters have heavier reduced-fat weight and muscle weight (P < 0.05) and significantly heavier reduced-fat weight/weight and muscle weight/weight (P < 0.05) than those of Level 2. In other words, relative reduced-fat weight and relative muscle weight will have greater reference value of guiding the scientific selection.5. Athlete's body compositions are closely related to the anaerobic metabolism ability, and Level 1 athletes have greater correlation than Level 2 athletes, among which muscle weight and anaerobic metabolism are at the highest correlation of all the indexes.
