Abstract
In the realm of tennis, the backhand stroke stands as a cornerstone, demanding a nuanced blend of power, precision, and command. Within this domain, two prevailing stances, square and open, have risen to prominence, each laden with distinctive biomechanical nuances and repercussions for performance. This exploration undertakes a dynamic deconstruction of the biomechanics inherent in these stances, with the overarching objectives of delineating their respective strengths and weaknesses, unraveling the biomechanical determinants influencing power, accuracy, and consistency in the backhand, and furnishing evidence-based insights for players and coaches to refine their backhand technique. The square stance, characterized by a frontal orientation of the shoulders towards the net, establishes a robust foundation for power generation. However, it introduces heightened ground reaction forces, potentially influencing joint loading and injury susceptibility. Simultaneously, it begets greater hip
