배구 선수들의 시합 전·후의 운동수행 특성과 혈중지질의 비교

Abstract

The purpose of this study is to analyze exercise performance characteristics and blood lipids changes before and after the game in volleyball players in order to suggest basic information about players’ physiological changes and provide and design more effective and scientific training methods. The participants of this study were 15 volleyball players of G University located in Gyeongsangnam-do and of C University located in Gwangju Metropolitan City. Their blood and exercise performance characteristics were analyzed before and after the game. Blood component changes were measured by the paired t-test analysis and the relationship between exercise performance ability and blood lipids were tested by correlation analysis. The level of statistical significance was set at p<.05. Finally, the following conclusions were drawn.<BR>First, volleyball playes’s blood lipids changes were analyzed before and after the game. There was a statistically significant decrease in TC(t=3.884, p<.01) and TRG(t=4.273, p<.01) before and after the game. Moreover, there was a statistically significant decrease in Non-HDL(t=3.291, p<.01) and GLU(t=1.847, p<.05) before and after the game.<BR>Second, correlation analysis was done to examine the relationship between exercise performance characteristics and blood lipids in volleyball players’ game. As a result, it was found that TC, LDL, and Non-HDL after the game were significantly negative correlation with mean heart rate, mean values of exercise intensity, and calorie consumption(p<.01).<BR>In conclusion, volleyball players need high level aerobic exercises for blood lipids changes and plyometric training, interval training, and core balance exercise to build up maximum muscle strength for short period to improve performance levels through exercise performance. It is, therefore, necessary to develop scientific and effective programs for volleyball players.
