In some of the studies covered in this systematic review, CK did not return to baseline within the times of measurement, while in other studies, CK returned to baseline 42, 48, 72 or 120 hours after a match. Peak CK after exercise and time-to-return to baseline appears to be greater in soccer and rugby in comparison to other team ball sports. This is likely to be due to the greater number of high-intensity efforts performed during a match, such as accelerations/decelerations, sprints, collisions, and total running volume.
Cortisol seems to peak immediately after a match and return to baseline in different time-periods (i.e. 14-72 hours). For the same reasons to CK, the recovery times of cortisol are also longer in rugby and soccer. Different findings can be found in testosterone changes after a match. There seems to be a trend for testosterone to decrease after a match and then increase in the longer periods of recovery (i.e. 24-48 hours post-match).
