Relationship between pre-training wellness scores and internal and external training loads in a Division I women’s lacrosse team

Abstract

ABSTRACT This study examined the relationship between pre-training wellness scores and internal and external training load outputs during the preparation phase of a Division I women’s collegiate lacrosse team. Athletes (n = 27) logged daily wellness (sleep, energy, stress, and how their muscles felt), session ratings of perceived exertion, and training metrics for 13 weeks. Load metrics were collected with microtechnology units. Repeated measures mixed linear models were constructed to evaluate the relationships between wellness and training load. The largest effects observed indicated: improved sleep was predictive of increased total distance (by as much as 310.5 m, 95%CI 36.7–584.3), high-intensity distance (by as much as 72.7 m, 95%CI 17.2–128.3), and Athlete Load (by as much as 6.8AU, 95%CI 1.8–11.8); more energy was predictive of increased total distance (by as much as 323.6 m, 95%CI 52.2–594.9) and Athlete Load (by as much as 5.6AU. 95%CI 0.6–10.5). For each one-unit increase in overall wellness score, total distance (3.5 m, 95%CI 1.2–15.1) and Athlete Load (0.2AU, 95%CI 0.0–0.3) increased. Pre-training wellness scores and sub-scores are predictive of external load training output. Monitoring athlete wellness systematically can help coaches with decision-making relevant to training and game performance.
