The tennis racquet design and string tension directly impact power generation. Modern racquets are constructed with materials that enhance stiffness and stability, allowing players to transfer more energy from their swing to the ball. Additionally, string technology, including composition and tension, affects the "trampoline effect," where the strings deform upon impact and then rebound, propelling the ball with greater velocity.
Secondly, the type of tennis ball used can influence power production. Faster balls, such as those used in professional tournaments, have lower compression and offer less resistance upon impact, resulting in higher ball speeds off the racquet. Conversely, slower balls with higher compression absorb more energy upon impact, reducing the speed at which they rebound off the racquet.
