AB - PURPOSE: The lower trapezius muscle (LT) and serratus anterior muscle (SA) are weakened muscles in a rounded shoulder position (RSP). This study examined the effects of isotonic and isometric exercises applied to the LT and SA on the shoulder height and respiratory function of college students with RSP.
METHODS: The subjects were 27 college students with RSP. The subjects were assigned randomly to two groups: the complex exercise group (n = 14) and the isotonic exercise group (n = 13). They performed the exercise programs for 30 minutes, three times a week for four weeks. The shoulder height and respiratory function were measured before and after exercise.
RESULTS: The shoulder heights decreased significantly after exercise in both groups. In the respiratory function, the FVC and SVC were significantly higher in the complex exercise group than in the isotonic exercise group. The FEV1/FVC was increased significantly after exercise in both groups, and the FEV1 and MVV increased significantly after exercise in the complex exercise group. CONCLUSION: Isotonic exercise and isometric exercise for strengthening LT and SA help improve the postural change for RSP, which could help improve the respiratory function. The complex exercise could have a more positive effect on the respiratory function than individual isotonic exercise.
