Effect of Reactive Balance Training Versus Conventional Balance Training on Dynamic Stability and Change-of-Direction Performance in Competitive Tennis Players

This study is a randomized controlled trial comparing two balance training interventions in competitive tennis players. Participants will be randomly assigned to either a reactive balance training group or a conventional balance training group. Both groups will undergo a supervised training program for 6 weeks, with three sessions per week. Each session will include a warm-up, a structured balance training program, and a cool-down phase. The reactive balance training group will perform exercises involving external perturbations, unpredictable stimuli, and sport-specific reactive movements such as sudden directional changes, partner-induced disturbances, and dual-task activities. The conventional balance training group will perform static and controlled balance exercises, including single-leg stance, balance board activities, and slow, predictable movements without external perturbations. Training intensity and duration will be standardized across both groups. Pre- and post-intervention assessments will be conducted to evaluate changes in dynamic stability and change-of-direction performance.

Inclusion criteria

• Male and female competitive tennis players aged 18-25 years.
• Minimum 2 years of regular tennis training experience.
• Currently training at least 3 sessions per week (minimum 60 minutes per session).

Exclusion criteria

• Recent injury (last 3 months)
• Neurological, balance or vestibular disorders
• Previous surgery
• Participation in any structured balance, neuromuscular, plyometric, or agility training program outside regular tennis practice during the study period.
• Use of ankle/knee braces or orthotic devices that may influence balance performance.
