Effects of uphill high-intensity interval exercise on muscle damage and exercise performance during recovery.

Background: Active recovery is believed to offer positive benefits related to exercise by improving recovery and potentially managing several symptoms following strenuous exercise. The current study aimed to verify the effects of a session of low-volume and uphill high-intensity interval exercise on muscle soreness and exercise performance within the recovery period after an exercise-induced muscle damage protocol.

Methods: Thirty-one young physically active subjects completed two identical test sessions following an exercise-induced muscle damage protocol, separated by a three-week period, in which they performed uphill high-intensity interval exercise or a passive recovery.
