The influence of coaching behaviors, experience, and training on children's physical activity levels during youth sport practices

The purpose of this study was to examine how coaching behaviors, coaching experience, and coach training relate to physical activity (PA) levels of children during their participation in a youth sport program. Youth soccer teams (N = 27) serving children ages 6-11 years were directly observed during one practice using momentary time-sampling procedures consisting of 30-s intervals (10-s observation, 20-s recording). Team coaches reported prior coaching experience, training, and demographic characteristics. Multilevel logistic regression was conducted to describe associations between coaching behaviors and intensity of children's PA. Interaction terms were added to the models to determine if the associations differed across girls-only, boys-only, and coed teams. ANOVAs were used to describe associations between coaching experience, coach training, and team PA level. Children were more likely to engage in moderate or vigorous PA when coaches were watching without verbal feedback (Odds Ratio [OR], 3.2, 95% CI = 1.70-5.83) or watching with verbal feedback (OR, 2.1, 95% CI = 1.27-3.59), compared to when the coach was disengaged, regardless of team sex composition. The number of prior seasons coached was positively related to team PA levels. These findings can be used to inform coaching strategies for promoting increased PA during youth sport practices.
