Purpose The purpose of this study was to compare the effect of aerobic training and inspiratory muscle training on muscle endurance and pulmonary function. Methods This study was conducted with 20 young women(mean age 19.5 years). Participant’s mean height was 161.4cm, and their mean weight was 57.7kg. During ten days, the experimental group(n=10) performed the aerobic training(40min) with inspiratory muscle training(20min) a day, and control group performed only aerobic training(40min) a day. Using a spirometer, forced vital capacity(FVC), Forced expiratory volume in one second(FEV1), and Maximum voluntary ventilation(MVV) were measured for pulmonary functions and using a timer, lab times of 800-meter sprints were measured for muscle endurance after training. Results There were no statistically significant differences the variation of muscle endurance and pulmonary functions between groups(p>.05), but improved statistically significant differences muscle endurance and pulmonary functions within experimental and control groups(p<.05). Conclusion Although there were improved the pulmonary functions and muscle endurance after aerobic training with inspiratory muscle training during ten days, no significant differences only aerobic training group. Therefore, we need to allow more times for improvement of the effectualness in inspiratory muscle trainings.
