The purposes of this study was to effects of the POWERbreathe training program on pulmonary function and shuttle run test in soccer players. Subjects were aged 20~21 years. There was classified two groups(exercise group 15, control group 15), total 30. Measured items for this study were rest pulmonary function test(VC, FVC, FEV1, PEF, PIF, MVV), during exercise pulmonary function test(VErest, VEpeak, RER, VT, VO2max, TET), and shuttle run test in the 12weeks before and after. Subjects of exercise group were participated an 12week POWERbreathe training program. Data were analyzed by two-way ANOVA with repeated measure method of SPSS accepting level for all significances was above p<0.05. Results of this study were as follows; In the rest pulmonary function test, exercise group were showed significant differences on the FEV1, PEF, PIF, and MVV in the 12week POWERbreathe training program. In the during exercise pulmonary function test, exercise group were showed significant differences on the VEpeak, RER, VT, VO2max, and treadmill exercise time in the 12week POWERbreathe training program. In the shuttle run test, exercise group were showed significant differences in the 12week POWERbreathe training program. This study showed that an 12weeks POWERbreathe training program affected in a positive effects in almost of items in trained soccer players, but not in untrained soccer players. These results support evidence that POWERbreathe training has beneficial effects on pulmonary function, shuttle run test and might be a factor that improve soccer players exercise performance.

This study aimed to determine the effects of the virtual reality respiratory exercise and conventional respiratory exercise on diaphragm movement and pulmonary function in patients with stroke. Thirty subjects with stroke (an average age of 54.9 years) were randomly allocated to virtual reality respiratory exercise (n=15, VR group), and conventional respiratory exercise (n=15, control group). The two exercises were performed for 30 minutes 2 times a week for 4 weeks. This study measured diaphragm movement and pulmonary function before and after each 4-weeks exercise. Ultrasonography was used for measuring the diaphragm movement, and AVAD9 was used to measure the pulmonary function; forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF). The control group showed a significant increase in PEF (p<.05), but no significant different in diaphragm movement, FVC, FEV1. The VR group showed a significant increase in all dependent variables (p<.05), except the FEV1. In comparison of two group, the VR group showed significant increases in diaphragm movement, FVC, and PEF relative to the control group (p<.05). Based on the above results, it can be concluded that the virtual reality respiratory exercise is more effective than conventional respiratory exercise on diaphragm movement and pulmonary function for rehabilitation in patients with stroke.
