Effectiveness of Dorsal Glide Mobilization on Ankle Mobility and Basketball Performance

Background Ankle dorsiflexion is a crucial factor for functional lower limb performance, particularly in sports like basketball, where dynamic movements, direction changes, jumps, and landings are essential for athletic success. Eccentric exercise has been shown to improve dorsiflexion range of motion (ROM), enhancing muscle strength, flexibility, and athletic performance. Additionally, ankle joint mobilization, specifically posterior talocrural glide, has demonstrated promising results in improving mobility, restoring ROM, and reducing compensatory movement strategies. However, the combined effects of eccentric exercise and joint mobilization on increasing ankle dorsiflexion ROM and improving athletic performance in young basketball athletes have not yet been sufficiently investigated. Objective The purpose of this study is to investigate the effectiveness of combining eccentric exercise and posterior talocrural glide mobilization in improving ankle dorsiflexion ROM and enhancing athletic performance in young basketball athletes. Methods A randomized controlled trial will be conducted, including 40 young basketball athletes with confirmed restricted ankle dorsiflexion ROM. Participants will be randomly assigned to an intervention group and a control group. Both groups will follow a five-week training program consisting of eccentric exercises and stretching, performed three times per week, to improve athletic performance. The intervention group, in addition to the exercise program, will undergo ankle joint mobilization sessions for the same duration. Ankle dorsiflexion ROM, maximum isometric strength of the ankle muscles, fatigue resistance through specific endurance tests, and performance via functional tests will be assessed at baseline, at the end of the five-week program, and three months after the intervention. Statistical analysis will be conducted using a two-way repeated-measures ANOVA, with the significance level set at p \< 0.05.
