[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.
