MSI, self-reported musculoskeletal injury; PA, physical activity.

^aper 1000 person-weeks.

^bBelow Guidelines (31) is <150 moderate to vigorous physical activity min/week; Meets Guidelines = 150–299 moderate to vigorous physical activity min/wk; Exceeds Guidelines is ≥300 moderate to vigorous physical activity min/wk. Vigorous minutes were multiplied by 2 and added to moderate minutes to get weekly minutes of moderate to vigorous physical activity. Guidelines category assignments are based on participant average weekly reported activity from the previous injury week (or baseline if none reported) to the prior week.
