Investigating factors which may influence recovery and preparation in professional rugby union. / Marc Rhys Jones

Swansea University Author: Marc Rhys Jones

Abstract

To enhance understanding of recovery and preparation in rugby union, the aim of this thesis was to examine the impact of competition on key parameters and investigate factors which may influence the recovery process from competition and training. The findings of study one demonstrate that movement p...
