ABSTRACT
OBJECTIVE:
The purpose of this study is to compare muscle strength, endurance and the change of myosin heavy chain isoform after sprint training(ST) and heavy resistance training(HRT).METHOD:
Fourteen young athletes were enrolled and were randomly assigned into each training group. Before and after training for 8 weeks, the strength and the endurance were evaluated using isokinetic exercise system(Cybex 6000). The specimens of muscle biopsy were obtained from vastus lateralis muscle and were analysed for muscle fiber type using one dimensional electrophoresis.RESULTS:
Peak torque, total work and mean power were increased significantly in both groups, but endurance ratio increased only in the sprint training group(P0.05).CONCLUSION:
This study shows that it is possible to increase muscle strength and to achieve fiber type transformation with the sprint training and the high resistance training.
