The objective of this study was to clarify the appropriate individualized initial intensity of muscle training on a Power Rehabilitation(PR) machine for middle-aged and elderly people from its relationships with the skeletal muscle mass and muscle strength (grip strength). The subjects were 50 males and females (mean age 63 years, range 43-79 years) participating in a PR fitnesss course. Seven training events were performed on the PR machine. The initial training intensity in these events showed considerably high correlations with the skeletal muscle mass (r=0.42-0.57, p<0.05) and grip strength (r=0.43-0.61, p<0.01). However, when regression equations were calculated, the level of significance was p<0.05 for grip strength, suggesting that the initial training intensity can be determined according to the grip strength. Also, as the perceived exertion scale (Bprg' s scale) presently used for PR was originally an index of general endurance, a new scale of perceived exertion concerning weight loading is proposed.
