This study sought to determine whether there is any difference on participation in regular exercise between middle-aged and older adults and to determine whether the benefits of regular exercise differed between middle-aged and older adults in terms of health capability, mood, or anxiety symptoms and life-satisfaction level. The results indicated that older adults engaged in regular exercise more frequently than middle-aged adults. In addition, exercise participants among middle-aged adults had the better health capabilities, lower depression and anxiety symptoms, and higher life-satisfaction level than nonparticipants. On the other hands, older adults tended to be negatively associated with depression and anxiety symptoms and be positively correlated with life-satisfaction level than middle-aged adults even if middle-aged adults had the better health capabilities. These findings might be beneficial to provide appropriate exercise programs, to prevent and minimize the negative symptoms of anxiety and depression, and to facilitate the life-satisfaction level.
