초록

The purpose of this study was to investigate fast twitch muscle(%) and fatigue index(%), relationship with aged according to isokinetic leg muscle strength in men and women adults people. Also, this study was to investigated differences with knee joint angle differences isometric knee strength. Subjects of this study were 57 (male n=30, female n=27) adult in men and women There was no significant differences in isokinetic concentric and eccentric knee extension between male and female in this subjects. Isometric knee extension concentric 60 ̊/sec are significant(p<.05) differences between other angle degrees. But isometric knee flexion concentric 15 ̊/sec was no significant differences between other angle degrees. Isokinetic endurance concentric quadriceps and hamstring peak torque are significant(p<.05) differences between adults male and female. But isokinetic endurance concentric quadriceps and hamstring was no significant(p<.05) differences between male and female in fast twitch muscle(%), fatigue index(%). There was significant differences in female between isokinetic endurance concentric quadriceps peak torque and age in results with simple regression analysis, but there was significant differences in male between isokinetic endurance concentric hamstring peak torque and age in results with simple regression. Relationship between isokinetic endurance concentric quadriceps, hamstring with fast twitch muscle(%), fatigue index(%) and age was no significant(p<.05) differences each male and female in results with simple regression analysis.
From these results suggest that it is less decrease ratio in fast twitch muscle(%) according to the age increase. Therefore further to try using fast twitch muscle(%) equation and another methods for the finding fast twitch muscle ratio, also try to more research with narrow age range in select sample subjects.
