Abstract
Square stepping exercise (SE) and BOSU ball exercise (BE) have independently shown beneficial effects on balance, strength, and coordination; however, their combined effects in badminton players remain unclear. This study aims to present the protocol of a randomized controlled trial designed to investigate the effectiveness of combined SE and BE on postural sway, dynamic balance, and vertical jump performance. Fifty-one badminton players will be randomly allocated into three groups: combined SE and BOSU group (SBG, n = 17), BOSU group (BG, n = 17), and control group (CG, n = 17). The intervention will last 8 weeks. The SBG will perform SE (three sessions per week) and BE (two sessions per week), the BG will receive BE with conventional training, and the CG will follow conventional training only. Outcomes will be assessed at baseline, week 4, and week 8, and post-intervention using the Y-Balance Test for dynamic balance, Wii Balance Board measures for postural sway, and the Sargent jump test for vertical jump performance. Data will be analysed using repeated-measures analysis of variance to determine within- and between-group differences over time. The findings of this study are expected to provide evidence on the effectiveness of combined neuromuscular and balance training strategies for improving lower limb performance and postural control in badminton players and reduce health risks in these athletes.
