Impact of Yoga Intervention on Physical Fitness Parameters in Preadolescent Children: A Randomized Controlled Trial

Abstract

Purpose: This study aims to assess the impact of yoga on physical fitness among healthy primary school children using a randomized control design. Material and Methods: A total of 52 children, aged 8-13, were randomly assigned to either the Yoga Group (n = 27, mean age = 10.48 ± 1.25 years) or the Control Group (n = 25, mean age = 11.20 ± 1.50 years). The participants underwent evaluation using the EUROFIT Test Battery as the primary outcome measure The Yoga Group engaged in 45-minute yoga sessions twice a week for a duration of 10 weeks, while the Control Group received no intervention. Outcome assessments were repeated at the conclusion of the 10-week intervention period. Results: Significantly positive enhancements were observed in the Yoga Group across various components of the EUROFIT Test Battery, including balance, speed, flexibility, muscle endurance, and cardiovascular endurance. Conclusion: These findings demonstrate that yoga interventions contribute to improvements in physical fitness among preadolescent children. Consequently, incorporating yoga exercises into the school curriculum is recommended, given their efficacy, minimal resource requirements, and positive impact on sports readiness.
