Before revision:  This model predicted an injury risk of ~3\% when activity increased by up to 50\% or decreased by up to 20\% ( 0.8 <= ACWR< = 1.5). Larger decreases in activity were associated with a decreased injury risk to a minimum of 1.5\% . Larger increases in activity were associated with an increased injury risk, from 3\% up to a maximum of 6\% at ACWR = 5. Girls were at significantly higher risk of injury than boys.
