Peptidase prevents loss of muscle strength after intensive training sessions

Intense exercise that involves stretching muscle contractions (eccentric or negative pull-ups) causes muscle damage and soreness. Delayed onset muscle soreness is worst during the days following exercise because muscle damage causes inflammation (i.e. swelling, redness and stiffness). Some studies have found that massage or medications such as Advil can reduce muscle soreness and stiffness, but do not restore normal muscle strength and energy. A study conducted at the University of Nebraska found that a peptidase supplement reduced strength loss and promoted recovery after intense eccentric exercise, but had no effect on pain or blood markers of delayed onset muscle soreness. Peptidase is an enzyme that breaks down protein. Peptidase supplements may promote recovery from eccentric weight training and membrane repair. Furthermore, they could restore blood proteins, which would lead to a reduction in swelling. (Journal Strength Conditioning Research, 21: 661-667, 2007)
