Abstract

Purpose:Partial body cryotherapy (PBC) has been shown to be beneficial for post-exercise recovery, however, no study has demonstrated the effectiveness of PBC as a recovery modality following elite rugby union (RU) training. RU is a unique sport that involves high velocity collisions with minimal pr...
