Squash has developed into a high-performance sport requiring speed, precision, and advanced technical control, especially with its inclusion in the Los Angeles 2028 Olympic Games. Among its key skills, the backhand drop shot is a decisive offensive action that depends on accurate coordination. However, its neuromuscular basis remains underexplored. This study investigates muscle activation patterns during the skill using electromyography, analyzing both upper and lower limb contributions across preparation, execution, and follow-through phases. The results indicate a coordinated, phase-specific neuromuscular pattern. Preparation focuses on stability and alignment, execution shows peak activation and force production, while follow-through ensures controlled deceleration and balance. Upper limb muscles primarily guide precision and racket control, whereas lower limbs support stability and energy transfer through a proximal-to-distal sequence. These findings highlight the importance of integrated muscle coordination, offering practical value for designing evidence-based training programs that enhance performance and reduce injury risk, Overall, the study provides valuable insights into the neuromuscular organization of a critical squash skill. The results have important practical implications for coaching and training, as they support the development of more targeted and evidence-based programs. By emphasizing coordination, timing, and movement efficiency, this research contributes to improving both performance quality and injury prevention. It also opens the door for future investigations into skill-specific muscle activity in squash and other high-intensity sports.
