(*) illustrates statistically different as CI does not include 0; (†) illustrates values that did not exceed Minimum Detectable Change; FR = foam rolling, RM = rolling massage; ‘d’ = Cohen's d; ‘baseline’ = average of the two baseline scores, ‘post 0’ = immediately after intervention, ‘post 10’ = 10 minutes after intervention, ‘post 20’ = 20 minutes after intervention, ‘post 30’ = 30 minutes after intervention
