근지구력 훈련이 Catecholamine 변화에 미치는 영향
홍장표,정위곤 龍仁大學校 體育科學硏究所 1996 體育科學硏究論叢 Vol.6 No.2
The purpose of this study was to investigate the effect of muscle endurance training on the change of catecholamine. All subjects were 8 males YUDO athletes on Y unive. they participated in weight training program for 12 weeks. Independent variables for the study were pre and post of training and conditions(rest, immediately exercise, and 30, 60min. after exercise), dependent value was epinphrine and norepinephrine. Exercise treatment for blood sampling was Bruce's stress testing protocol. For data analysis used MANOVA of SPSS and critical level for significance was α 0.05. The result of study can be summarized as follows. 1. Epinephrines were showed nonsignificant differences between the pre and post aerobic exercise training. And the nature of epinephrines changes were showed same aspect. 2. Norepinephrine were significantly decreased after muscle endurance training program at rest. So, muscle endurance training were effected on norepinephrines decreas, and interection effect exist between muscle endurance training and conditions. As, above results this study can suggested that muscle endurance training program can't effect the changes of epinephrine, but can decrease norepinephrine releasing level.
Glucose 투여가 최대운동시 혈중 젖산변화에 미치는 영향

The purpose of this study was to investigate the effect of Glucose on changes and recovers of blood lactate after all-out treadmill run exercise as metabolism response by temporary treatment of Glucose. All subjects were 8 males football athletes on university who divided into 6 groups(placebo and during, 0, 15, 30, 60 min. before exercise) according to dosage time conditions. Therefore, the design for this study was repeated measurement within group and between groups as independent variations were dosage time and exercise condition as blood sampling time(resting immediately, 10, 20, 30 min. after exercise), dependent variations were blood lactate with recorded performance time of all subjects. The protocol for exercise load was Bruce Treadmill Protocol running from rest to all-out state progressively. All raw data were analysed by MANOVA for statistical significance. The following conclusion was made : Lactate showed significant changes according to 5 conditions. All groups showed the highest level at immediate exercise, dosed group at 30 min. before exercise was the highest level with the lowest level on dosed group at just before exercise(p<.001). Lactate showed significant changes among 6 groups (p<.05). There were also showed higher on dosed grouts than control grouts in recovery rate with the highest level on dosed group at 60 min. before exercise.
