This study aimed to evaluate changes in player’s sit and reach flexibility, 10m acceleration, and 35m velocity speed following a high velocity low amplitude manipulation (HVLAM) by a chiropractor.
Nineteen male student level rugby union players participated in this double blinded, randomised design study. Results demonstrated that a single encounter of pre-event HVLAM had a positive effect, increasing player’s flexibility scores, and decreasing their short distance sprinting performance times.
