The versatile design of Hesacore expands the contact surface between the hand and the grip. As a result, Hesacore creates between 8% and 14% more traction, depending on the overgrip used by the player. This means that the player can hold the grip with less effort and finger contraction, while the grip does not slip from the hand. When hitting the ball, the contraction of the hand muscles (particularly the middle and ring fingers) is directly related to the contractions that occur in the wrist and arm. All this muscle activity affects the effectiveness of the hit, as a tight and sharp movement would prevent the efficient transfer of energy to the ball. Unlike traditional grips, players using Hesacore appreciate the fact that the grip does not slip from their hands. Better traction relaxes and eases the muscles, from the hand to the arm, contributing to a more fluid and harmonious movement. The ball comes off the racket in a controlled manner, heavier and faster.
