This study aimed to investigate the short-term effects of repositioning exercise on changes in forward head posture and rounded shoulder posture in college swimmers. Participants in this study are members of KKU Aquatic Club, Khon Kaen University, 36 males, mean age 21.58±1.98 years, mean weight 73.42±12.10, mean height 1.75±0.05 meter, mean body mass index 23.97±3.46. Participants were divided into two groups by block randomization method. The first group is the repositioning exercise group doing reposition exercises three times per week, about 30 minutes each for four weeks, with the researcher controlling and supervising the exercise. The control group was the second group that performed regular swimming training. The variables in the study included the craniovertebral angle, pectoralis minor index, DASH-SM questionnaire, and 50-meter freestyle swimming time were assessed before the study (1st week) and end of the study (4th week). When comparing the effect of reposition exercises on the change within the group in the fourth week, the repositioning exercise group had a statistically significant increase in the variables such as craniovertebral angle (p=0.001), right pectoralis minor index (p=0.001), DASH-SM questionnaire score (p=0.03) and 50-meter freestyle swimming time were reduced statistically significant (p=0.019). The control group did not have statistically significant among all variables. Moreover, when comparing the effect of the repositioning exercise on the changes in the variables between the groups, there was no statistically significant difference for all variables (p<0.05). Summarizing the experiment results, it was found that if increasing the duration of exercise or modifying the exercise posture may result in more apparent differences and help correct forward head posture, rounded shoulder posture, helping to reduce shoulder injuries, and increase the performance of the swimmer.
