Association of the acute:chronic workload ratio and wellness scores in premier league male hockey players

Abstract

Background: The relationship between acute:chronic workload ratios (ACWR) and the incidence of injury, as well as the relationship between subjective  wellness scores and training load, is unclear in hockey players.
Objectives: This study investigated these relationships to determine if the ACWR is a useful workload management tool for field hockey players. In  addition, the study investigated the association between specific subjective wellness scores (fatigue, sleep quality, general muscle soreness, mood and  stress level) and the acute:chronic workload ratio and training load. The study also assessed the association between individual players’ training loads  with the self-reported wellness scores.
Methods: Fourteen male field hockey players from the men’s first team at the University of the Witwatersrand participated in the study over ten weeks  during a premier league competition phase. A Google form was completed within thirty minutes of every training session/match. This form consisted of  questions that allowed for the calculation of the ACWR.
Results: No incidence of injury was reported during the tenweek period. ACWR scores ranged between 0.67 and 1.87. The ACWR was associated with  general muscle soreness (p = 0.010) and training load was associated with fatigue (p = 0.002), sleep quality (p = 0.05), general muscle soreness (p = 0.004), and mood (p=0.025).
Conclusion: There may be some merit in the use of subjective wellness measures as workload management tools in field hockey. Further research is  required to determine if there is an optimal ACWR for this sport.
