| Research Abstract |
This study aimed to develop a method for the in-house training of middle-aged and elderly adults. First, we investigated the effects of a well-rounded exercise regimen for enhancing lower extremity muscle strength, balance, flexibility, and cardiorespiratory fitness on subjects. This training was conducted once a week for 24 weeks at a fitness center, with each session lasting for 90 min. The effects of this training were visible in terms of increased flexibility, functional mobility, lower extremity strength, and cardiorespiratory fitness. Next, since we needed to develop a new resistance-exercise scale of perceived exertion for in-house training, we examined the concurrent validity of the newly developed Japanese scale (S-scale) of perceived exertion, using young adult men who performed the biceps curl. The S-scale for active muscles has six categories from 1 (yo-yu) to 6 (mou-genkai), with a verbal description for each. A linear relationship was observed between each category of the

S-scale and the root mean square (RMS) values of surface electromyography. Therefore, the category of S-scale for the active muscle can be used to assess the magnitude of perceptual and physiological signals during resistance exercise. Third, we investigated the effect of the biceps curl with imposed-intensity bouts, on the S-5 (kanari-kitekita) scale. Twelve healthy middle-aged women performed the unilateral (non-dominant arm) biceps curl using a 2-to 2.5-kg dumbbell until S-5 scale intensity. The dominant arm did not exert any effort and only aided control. The subjects trained for 12 weeks, performing one set of exercise for 2-3 times a week. After training, the elbow flexion for the trained and untrained arms showed significant increases of 22% and 16%, respectively, and dumbbell curl repetition for the trained arm increased by 59%. These results suggest that the resistance exercise with the S-scale of perceived exertion is a practical method for in-house resistance exercise training. Less
