Pre-competition and recovery strategies in elite sport: the use of vascular occlusion and ischemic preconditioning / Natalie Williams

Swansea University Author: Natalie Williams

DOI (Published version): 10.23889/Suthesis.43713

Abstract

Understanding competition demands and training are only two components that impact overall perfonnance which have been previously established in the literature; pre-competition and recovery can also improve athletic performance. However, considerably less research has been conducted in elite populat...
