Combined Aerobic and Respiratory Exercise Improves Lung Function and Body Composition in Overweight Adults: A Pilot Study

Purpose: This study aimed to examine the effects of a 4-week combined cycling and breathing exercise program on pulmonary function and body composition in overweight adults. Methods: Seventeen participants (body mass index≥23) were randomly assigned to an experimental group (n=8; cycling combined with breathing exercises) or a control group (n=9; cycling only). Each 30-min session was conducted at 60 rpm, with the intensity set at 60 %-80% of the individual’s maximum heart rate. The experimental group used a resistance-based respiratory training device during cycling. Pre- and post-intervention assessments included pulmonary function, diaphragm thickness and movement, and body composition. Results: The experimental group demonstrated marked improvements in forced vital capacity (FVC) and diaphragm thickness and movement. They also showed a reduction in fat mass and increases in fat-free mass and basal metabolic rate (BMR). Conversely, the control group improved only in diaphragm movement. Between-group comparisons revealed greater improvements in FVC, diaphragm movement, fat-free mass, and BMR and greater fat mass reduction in the experimental group. Conclusion: The results indicate that the integration of cycling and breathing exercises can yield synergistic benefits, improving both cardiorespiratory function and body composition. This combined approach may serve as a practical and effective intervention for improving physical fitness; however, further investigation in clinical settings is desired.
