Effects of Aerobic and Resistance Training on Body Composition and Physical Capacity of Adolescents with Cystic Fibrosis

摘要

The study investigated the effects of a 12-wk training program combining aerobic and resistance training on body composition and physical capacity of adolescents with cystic fibrosis. The run/walk in treadmill program had duration of 23 min in a moderate to high intensity. The resistance training consisted of 2 sets of 10 reps for the following exercises: lat pull down, leg press, chest press, shoulder press, and sit-ups. The resistance training was performed with dumbbells and pulley machines. Before and after intervention, several evaluations were conducted: body composition by Slaughter`s equations, aerobic capacity by ergospirometry, and muscle endurance by push-up and sit-up tests. Significant increase in the fat free mass (P=0.01) was observed throughout the training period. Although the total body weight increased (P=0.02), no change was found in fat mass (P=0.24). Maximum oxygen uptake (P=0.03) and abdominal muscle endurance (P=0.04) were also significantly improved. Thus, the findings indicate that a supervised exercise program combining aerobic and resistance exercises significantly improved body composition, aerobic capacity, and abdominal muscle endurance in adolescents with cystic fibrosis.
