PURPOSE: This study investigated the effects of resistance exercise on cardiopulmonary functions in young sedentary subjects. SUBJECTS: Forty-two young and healthy subjects with a sedentary lifestyle were included in this study. METHODS: The subjects were randomly divided into 2 groups: control and experimental. The control group (n = 21) received health education and continued with normal activities of daily living. The experimental group (n = 21) underwent resistance training, health education, and continued with normal activities of daily living. The resistance exercise program consisted of 3 postural exercises: chest press, dumbbell pullover, and flat-bench dumbbell fly. The subjects received this intervention 3 times/week for 8 weeks. RESULTS: The baseline characteristics were comparable between the 2 groups. The 6-minute-walk test score, peak expiratory flow, forced vital capacity, forced expiratory volume in 1 second, maximal voluntary ventilation, and chest expansions were significantly improved post-intervention in the experimental group and between the 2 groups. CONCLUSION: Cardiopulmonary functions in young sedentary subjects were significantly improved with the 8-week resistance exercise program.
