Research Abstract

The purpose of this study was to develop a new training method for improving muscular performance in the the intermittent exericise which is composed of repeated short term masimal bouts. The study included following two experiments.
Experiment 1: Musucularperformance and energy metabolism of various king of intermittent maximal pedalling exercise was examined with varing the duration of rest as well as exercise phase. When varing the rest duration (50sec.,20sec.,10sec.,and 0sec.:continuous exercise) with fixing the exercise duration(10sec), the 10nger the resting duration, the larger the energy of the exercise depending on alactic (ATP-CP) system. On the other hand, the shorter the resting duration, the larger the contribution of lactic(anaerobic glycolysis)as well aerobic systems. When vering the exercise duration (5sec.10sec.,and 20sec.) with fixing the rest duration (20sec.), the shorter the exercise duration, the larger the contribution of the energy from alactic systems. On the co ntrary, the longer the exercise duration, the larger the contribution of the energy from lactic as well as aerobic systems. These results suggest that when the exercise duration is relatively shorter and rest duration is longer, the energy of the exercise depends much on alactic energy system, and reversely when the exercise duration is relatively longer and rest duration is shorter depend much on lactic as wells aerobic system.
Experiment 2:Training effect of the intermittent exercise was examined. The exercise was composed of 10sec.maximal effort pedalling bout which repeated 10times, between each bout 20sec. rest was given. The taraining was performed 3 times per week and continued 2 months. After the training muscular performance improved both peak power and endurance capacity. Energy delivering capacity of all three systems also improved.
In conclusion, at intermittent exercise, energy delivery pattern and muscular performance is affected by the length of exercise as wellas rest duration. Therefore making training regiman considering the combination of exercise and rest duration may be quite important. Farthermore if the combination is adequately fit for training objective, intermittent exercise training is very effective method for improving wide energy delivery systems including alactic, lactic, and aerobic pathway and then improving muscular performance including both momentary peak power and endurance capacity.
