Nausheen S, et al. - Authors planned this work to compare the preconditioning effect of 10% eccentric exercise contraction [EEC] vs. low-level laser therapy (LLLT) on subjective, physiological, and biochemical markers of muscle damage in elbow flexors in collegiate men. As per observations, light-load eccentric exercise seemed to provide similar protective effect against subsequent maximal eccentric exercise as LLLT. They suggested using both the treatments reciprocally as per the patient preference, costs, and feasibility of the equipment.
