Arm Swing Exercise Improves Exercise Capacity and Oxygen Consumption in Overweight and Normal Weight Sedentary Young Adults

摘要

The purpose of this study was to investigate the effects of arm swing exercise (ASE) training on exercise capacity and cardiac autonomic activity in overweight and normal weight sedentary young adults. Forty sedentary volunteers were recruited and classified into two groups according to their body mass index (BMI). Subjects in both groups, overweight (age 20 ± 0.36 yrs, BMI 27.46 ± 1.52 kg?m ~(-2) ) and normal weight (age 20 ± 0.66 yrs, BMI 20.50 ± 1.75 kg?m~(-2) ) were matched for age and sex. They took part in the ASE training program for 2 months, 30 min?d~(-1) , 3 d?wk~(-1) . Before and after carrying out the training program, the 6-min walk distance (6MWD), peak oxygen consumption (VO_2 peak), heart rate variability (HRV), HR recovery, and HR reserve were determined for both groups. There were significant increases in the 6MWD and VO_2 peak in both groups after the ASE training (P 0.05). The overweight group also showed significantly higher resting HR, SBP, DBP, and MAP than the subjects in the normal weight group (P<0.05). This study indicates that overweight and normal weight sedentary young adults can improve exercise capacity and VO_2 peak but not in cardiac autonomic activity after 2 months of ASE training
