카누선수의 암에르고미터 운동시 혈중 젖산, LDH와 CPK 활성변화

다국어 초록 (Multilingual Abstract)

The purpose of this study comprised the difference on the changes of CPK and LDH activities in serum and the changes of lactate concentration in blood during arm ergometer exercise between Canoeists and Non-athletes. The subjects were 5 male middle school student(non-athletes) and 5 male middle school student(non-athletes) and 5 male middle school Canoeists(athletes). Exercise protocol were incremental maximal exercise and blood sample were collected preexercise, post exercise(all out), and recovery phase 30 minute. The obtained results are as follows: 1. Maximal oxygen uptake(peakVO_2) were significant differences between Canoeists and Non-athletes(P<.05). Maximal oxygen uptake(peakVO_2) in Canoeists were significantly higher than Non-athletes(63.74±7.62 vs 57.23±8.29ml/kg/min, respectively). 2. The blood lactate concentration were significant differences between Canoeists and Non-athletes. and There were significant change in two groups according to time period and There were significant differences in interaction of between group and time period {[F_(1.7) = 10.578, P =.014], [F_(2.14) = 42.536, P = .000],[F_(2. 14) =54.171, P =.000], respectively}. There were significantly increased after exercise as compared with pre-exercise Canoeists and Non-athletes and then decreased in the recovery phase. The results of LSD test, lactate concentration in pre-exercise was no significant differences. But lactate concentration in Canoeists were highly increased than Non-athletes after maximal exercise, and then were rapidly decreased than Non-athletes in the recovery phase. 3. The activities of CPK were significant differences between Canoeists and Non-athletes. and there were significant change in two groups according to time period. There were significant differences in interaction of between group and time period{[F_(1. 7) = 8.079, P = .0222], [F_(2. 14) = 48.289, P = .001], [F_(2. 14) = 1.550, P = .247], respectively}. There were significantly increased after exercise as compared with pre-exercise in Canoeists and Non-athletes and then decreased in the recovery phase. The results of LSD test, CPK activities in pre-exercise of Canoeists were significantly higher than Non-athletes. and were highly increased than Non-athletes after maximal exercise, and then were rapidly decreased than Non-athletes in the recovery phase.
