The purpose of this study was to investigate the difference of isokinetic muscular function(muscle strength & power, peak torque%BW, H/Q ratio) of knee joint between the ages of 50-70 years. For the purpose, men aged 50 and above(32 subjects), men aged 60 and above(25 subjects) and men aged 70 and above(15 subjects) were tested. The results were as follows;1. There was a significant difference in muscle strength according to the ages of 50 to 70 years2. There was s significant difference in muscle power according to the ages of 50 to 70 years3. There was not significant difference in PT%BW between 50 and 60 years 4. There was significant difference in PT%BW between 50 and 70 years 5. There was significant difference in PT%BW between 60 and 70 years 6. There was not a significant difference in H/Q ratio according to the ages of 50 to 70 years.
