Purpose: This study investigated the effects of a repositioning exercise on changes in a forward head posture with round shoulders in electronic sports (Esports) athletes. Methods: Forty-eight (36 males and 12 females) Esports athletes aged 18-25 years, who spent 6 hours/day for at least 6 months, with a craniovertebral angle (CVA) of less than 50 degrees, and visual analog scale (VAS) of less than or equal to 4, were randomly allocated into experimental (n=24) and control (n=24) groups. The experimental group (EG) received the repositioning exercise program of 40 minutes/day, 3 days/week, for 6 weeks. The control group (CG) did not receive any intervention other than routine tasks. CVA, pectoral minor index (PMI), and heart rate variability (HRV), EQ-5D-5L were assessed at baseline, after 4 weeks, and after 6 weeks, respectively. Results: There was a statistically significant increase in CVA between-group at 4-week (p<.05), and 6-week (p<.05) in the EG. The EG had a significantly greater increase in CVA than the CG at 4-week [p=0.04, ES (95%CI) = 0.08 (0.01-3.91)] and 6-week [p=0.002, ES (95%CI) = 0.19 (1.38-6.03)], whereas the PMI and HRV did not differ significantly between groups. Conclusions: The repositioning exercise can improve CVA in Esports athletes. However, there was no change in PMI and HRV.
