Background: Basketball, a popular sport, often leads to ankle injuries, prompting the need for effective preventive training. Has been illustrated that plyometric, balance and PNF trainings effect to reduce the injury rate between basketball players but they are not enough to enhance the electrical activities of ankle muscles.
Objectives: This study aimed to compared the effects of plyometric, balance, PNF (proprioceptive neuromuscular facilitation) and combined trainings on ankle muscle electrical activity (TA, PL, GM, SL) during single-leg jumps. While previous studies have examined ankle muscle activation during jumping, none have systematically analyzed electromyographic patterns across all four biomechanical phases; our study provides the first comprehensive phase-by-phase assessment to identify precise neuromuscular deficits and optimize injury prevention strategies for basketball players. 
Method: The study participants consisted of 75 young basketball players (aged 12–16 years) with no history of ankle injuries and participants were randomly assigned to five equal groups (n=15 each). The single-leg box jump test was systematically analyzed across four biomechanically defined phases.
Result: Results indicated that combined training was most effective in reducing electrical ankle activity. Plyometric training decreased activity in TA, PL, and SL (phase 1), GM and SL (phase 2), and GM and TA (phases 3–4). Balance training influenced TA and PL (phase 1), GM (phase 2), GM and SL (phase 3), and TA (phase 4), while PNF showed no significant impact. 
Conclusion: The study concludes that while individual training methods improve specific aspects of ankle stability, combined training offers a comprehensive solution by enhancing strength and reducing injury risk across all jump phases, making it ideal for warm-up protocols.
