Differences in the blood levels of fatigue inducing substances in rock fishing participants depending on the severity of obesity
This study aimed to clarify any differences in the blood levels of fatigue inducing substances in rock fishing players between before and after a game. To do so, subjects were assigned to either normal group or obese group on the basis of BMI 25, and statistical analyses with paired t-test were performed to determine inter-group differences. The results of this study are summarized as follows: First, for changes in the blood levels of ammonia, the levels increased after a game than before a game, with significant difference seen in obese group (p<.05). Second, the blood levels of free fatty acids (FFAs) decreased after a game than before a game, with statistically signific ant difference in obese group (p<.01). Third, the blood levels of inorganic phosphate increased after a game compared to those before a game, with no statistically significant difference in both the groups. Fourth, the blood levels of potassium (K+) increased slightly after a game compared to those before a game. No statistically significant difference was found in both the groups. Fifth, the blood levels of sodium (NA) increased slightly after a game compared to those before a game. No statistically significant difference was found in both the groups. Finally, the blood levels of lactic acid increased in both the groups, and statistically significant difference was seen in normal group (p<.01). Based upon the results above, although changes in blood fatigue factors before versus after a rock fishing game were examined in this study, it is expected that a further study of changes in blood and muscle fatigue factors over time will be able to estimate the progress of fatigue during rock fishing activities.
현대사회에 있어서 신체활동 연구의 주요 탐구과제는 ‘신체활동을 통한 교육’으로부터 ‘인간의 기본적인 움직임’을 목표로 하는 스포츠적인 움직임을 중심으로 한 생명 활동의 개념으로 급속히 변화되고 있는 추세이다. 이러한 환경변화에 대응하기 위하여 본학회는 ‘체육’적인 요소에서 ‘스포츠’적인 요소를 중심으로 한 학문적 정체성을 견고히 하고, 정기적인 학술지 발간과 학술활동을 통해 한국스포츠츠 문화의 발전과 학문적인 발전에 기여하는데 그 목적이 있다.
