Isokinetic knee extension performance characteristics measured before (Pre) and after (Post) training in Study 1

	ACT			CWI			Between-group	Between-group

d, Cohen’s effect size. Main effects existed for time (P < 0.001) and time × group (P = 0.034) for the work performed over contractions 1−25. No main effect for time or interaction existed for maximal isokinetic torque, or the work performed over contractions 26–50. ^**P < 0.001 change from Pre. Exact P values and d are also displayed for relative differences between groups. ACT, active recovery group; CWI, cold water immersion group. All data in this table are mean ± SD.
