Effects Of 12 Week Upper Limb Strength Training Combined with Ergonomic Intervention When Compared to Static Stretches in Youth Esports Players - A Quasi Experimental Study

Background: Mobile esports players are vulnerable to musculoskeletal issues due to prolonged poor postures and repetitive upper limb movements. Objective: To evaluate the effectiveness of ergonomic interventions and upper limb strength training in improving musculoskeletal outcomes in collegiate esports athletes. Design: Quasi-experimental study. Methods: 46 collegiate mobile esports players were divided into Ergonomics + Strength Training (EST) and Ergonomics + Static Stretching (ESS) groups. Ergonomic correction and strength training were implemented over 12 weeks. Outcomes included RULA scores, grip strength, assessed at baseline, mid, and final phases and QuickDASH scores were assessed at the end of every week. Results: Repeated measures ANOVA showed significant improvements in RULA (F=899, p<0.001), QuickDASH (F=74.4, p<0.001), and grip strength (F=1010, p<0.001) in the intervention group compared to controls. Conclusion: Ergonomic correction and upper limb strengthening improve functional outcomes in esports players, suggesting the need for structured training and ergonomic education in this population.
