EFFECT OF WRIST WRAP IN HANDGRIP STRENGTH IN CROSSFIT.

Abstract

Analyze wrist wrap influence on the values of maximum handgrip strength and dynamic resistance. A controlled randomized cross-over trial including 54 Crossfit participants randomly assigned to two groups. Group 1 began the series of tests with control wrapping, and Group 2 started with functional wrapping. Alternate series of four dynamic grip strength resistance tests were performed, and the resistance and fatigue values were calculated. The values obtained from the grip tests did not indicate any effect from the wrist wrap for an increase in maximum grip strength (35.7 vs. 35.6 kg; p=0.737) or greater endurance (78.2 vs. 77.8%; p=0.549). Fatigue was also equal in both groups (mean differences between the groups: 0.1 kg, CI= -0.7-0.8; p=0.779). The hypothesis that using a wrist wrap increases maximum strength and dynamic handgrip endurance was rejected in this study. Evidence Level I; Randomized control trial .
