Influence of Wrist Taping on Handgrip Strength in Crossfit Athletes
A study testing Wrist taping in people with Sport Injury and Hand Injury Wrist, run by Vita Care at 1 site in Brazil.
Trial 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. Read more about this study

About this study
Official title: Influence of Wrist Taping on Handgrip Strength in Crossfit Athletes - Crossover Randomized Controlled Trial
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.
