Abstract

This study investigated the effects of a high load resistance priming session on perceptual,physiological and performance responses in female rugby athletes. Using a randomizedcounter-balanced crossover design, ten highly trained female rugby players (mean ±standard deviation: age 23.4 ± 3.7 years;...
