Brief Summary

The idea that the use of a wristband can increase the grip strength is old, but without systematic scientific evidence. Most Crossfit practitioners wear wrist bands during training because it is believed that the wristband increases the grip strength of the hand. The aim of this study is to to analyze the influence of the use of the wristband on the maximum force value and on the dynamic resistance of hand hold. A simple blind randomized cross-over trial will be performed.
