國家跆拳道運(yùn)動員在全國錦標(biāo)賽中實(shí)時心率監(jiān)控和血乳酸變化特點(diǎn)的研究
[Abstract]:SUUNTO team heart rate real-time telemetry system was used to monitor the changes of heart rate of national taekwondo team athletes in the national championships and to collect 3min blood lactic acid after the competition. This paper analyzes the competition intensity of domestic taekwondo athletes in high level events. The results show that the average heart rate of female athletes can reach (174.43 鹵5.90) / min, male athletes' average heart rate can reach (172.19 鹵10.28) / min, / min;. The average heart rate of female athletes was (170.09 鹵6.04) times / min, male athletes' average heart rate was (167.43 鹵11.12) beats / min; during interbureau interval. The blood lactic acid of 3min female athletes was (8.27 鹵3.29) mmol/L, after the match. The blood lactic acid of male athletes was (9.36 鹵1.69) mmol/L.. Conclusion: 1) the average intensity of taekwondo match is more than 90% maximum heart rate, and the physiological load of interval can exceed 85% maximum heart rate; 2) the intensity of the competition is affected by many factors, such as the competition level, the level gap between the two sides, the important degree of the match, the change of rules and so on; 3) ATP-CP energy supply system and glycolysis energy supply system are the main energy supply system in Taekwondo competition, and aerobic metabolism energy supply system is auxiliary to improve lactic acid elimination capacity, increase ATP-CP energy storage and speed of rapid recovery. Taekwondo athletes for the promotion of special sports ability has important significance.
