  1. Group mean values and standard deviations. Only values for players who completed pre and post tests are presented. All between-group differences are in favor of the Nordic group. The sprint test performed was 30 meters sprint with standing start and split times after 5 and 10 meters (n = 9 in the intervention group and n = 5 in the control group). The jump test performed was a counter movement jump (CMJ; n = 9 in the intervention group and n = 8 in the control group)
