ABSTRACT
Rounded shoulder posture (RSP) can be seen quite frequently today. As a result, there are many problems that occur concerning lung capacity, attention span and muscle strength. Therefore, this study investigates the effects of posture-improving exercises on lung capacity, concentration, and muscle strength. At total of 24 college students participated in this study. Participants were measured for both shoulder height, and muscle strength (Trunk Muscle Strength Test). After pretest measurements, participants were divided into 2 groups. The shoulder stabilization exercise group (SSEG, n1=12) and the antagonist strength exercise group (ASEG, n2=12). Each group participated for 4 weeks. SSEG and ASEG exercised with a trainer 3 times a week for 30 minutes. Post-test measurements were taken after 4 weeks. There was a significant difference in both shoulders (left, right) RSP(p=.020, p=.030), and trunk muscle strength(p=.024) for SSEG and ASEG. Between two groups there were significant differences. This study has found that strengthening exercise is more effective in RSP reduction. However, it is the opinion of the researchers that the 4 weeks exercise period was not long enough to achieve significant results for other measurements. Further comparative studies related to the effects of strength exercises on RSP reduction, lung capacity, and trunk muscle strength is necessary.
