[Purpose] The aim of this study was to clarify the lung capacity when a balloon-blowing exercise was used to increase patients’ lung function. [Subjects] The subjects of the study were 30 young smokers. [Methods] Subjects were randomly divided two groups; The experimental group (n=15) performed a balloon-blowing exercise. The control group (n=15) performed no exercise. [Result] The results indicate that VC, ERV, IRV, FVC, FEV1, FEV1/FVC, PEF significantly improved in the experimental group. In contrast, VC, ERV, IRV, FVC, FEV1, FEV1/FVC, PEF did not significantly change in the control group. There were significant differences in VC, ERV, IRV, FVC, and FEV1 between the experimental group and the control group after the performance of the balloonblowing exercise. [Conclusion] These findings suggest that the balloon-blowing exercise has positive effects on lung function.
