태권도 경기시 스트레스 호르몬과 혈액성분 변화에 미치는 영향

Abstract

The purpose of this study was to compare changes in stress hormones and the influence on changes in blood constituents during Taekwondo sparring. Subjects were selected from two distinct group; Group A of 5 TaeKwonDo performers who had won more than 3 times within 1 year in national tournaments and Group B of 5 performers who had never won in any national tournaments within a year, for a combined total of 10 participants with a range of age from 20 to 23 years of age. The levels of stress hormone constituents(Epinephrine, Norepinephrine, and Cortisol) and blood constituents (Creatinine and Lactate) were measured at certain times; resting time(10 minutes), immediate time after 3 rounds of sparring(3 minutes for one round with 1 minute breaks between rounds) and recovery time(10 minutes). Then the statistically significant differences existed and Turkey verification was used afterward. An independent t-test was used for appearing meaningful differences between the groups and the maximum alpha level for all statistical tests were set at p<.05
