The subjects were divided into three groups: 1) taikyokuken group, 2) tennis group, and 3) sedentary group. Grip strength, reaction time, one-leg balance with opened and closed eyes, body front-flexion in a sitting position, and shuttle walk were measured as the physical fitness test for each subject. The following results were obtained: 1) All parameters of physical fitness were significantly (p<0.05) lower in the sedentary group than those in the regularly exercising group. 2) Little difference was made between taikyokuken group and tennis group in all parameters except body front-flexion in a sitting position and shuttle walk in the physical fitness test. 3) There were significant (p<0.01~0.05) correlations between the score of grip strength, reaction time, and one-leg balance with opened eyes and the concentration o f expired NO. 4) A significant correlation (p<0.01) was found between the score of shuttle walk and the concentration of expired N2O. From these results, it was suggested that expired nitrogen gases, especially the concentration of N20 at rest, could be a useful index of physical fitness and/or defense fitness in middle-aged and elderly people.}, pages = {65--71}, title = {呼気窒素ガスからみた中高齢者の体力}, volume = {25}, year = {2002} }
