For the purpose of this study, a collection of young golfers was divided into two groups. One group trained with Redcord tools using ActivCore FEX™, while the second group performed a standard strength-training regimen. Both groups worked out the same amount of time, twice a week for eight weeks. A golf clubhead speed test was taken before and after the training period. Clubhead speed has a measurable impact on the distance one can hit the ball.
A study conducted with a Norwegian soccer club showed that soccer players who trained with Redcord tools substantially improved the strength of their shot which resulted in a faster traveling ball. There was also a measurable improvement in overall balance and stability compared to the group that exercised with standard strength training.
