Purpose: Basketball, a popular sport, often leads to ankle injuries, prompting the need for effective preventive training. It has been illustrated that plyometric, balance and proprioceptive neuromuscular facilitation (PNF) trainings reduce the injury rate between basketball players; however, these trainings alone are not sufficient for fully enhancing ankle muscle electrical activity. 
Objectives: This study aimed to compare the effects of plyometric, balance, PNF and combined trainings on ankle muscle electrical activity (tibialis anterior [TA], peroneus longus [PL], gastrocnemius medialis [GM], soleus [SL]) during single-leg jumps. Although previous studies have examined ankle muscle activation during jumping, a systematic analysis of electromyographic (EMG) patterns across all four biomechanical phases has not been comprehensively conducted. This study offers a comprehensive phase-by-phase assessment to identify precise neuromuscular deficits and optimize injury prevention strategies for basketball players.  
Methods: 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.
Results: The results indicated that combined training was most effective in reducing electrical ankle activity in specific ankle muscles. 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 a suitable option for inclusion in warm-up protocols.
