  • PURPOSE: To determine if transdermal magnesium chloride (MgCl2) increases isometric force production and reduces muscle soreness after eccentric exercise. METHODS: In a double blind trial, participants were randomly assigned to a supplement before completing isometric force and muscle soreness testing. After 6 sets of 12 eccentric knee extensions, force and soreness were reassessed at 0, 24, 48, and 96 h. Supplements were applied three times per day. The other condition was repeated on the contralateral limb. RESULTS: Peak torque significantly decreased by 20% after eccentric exercise. At 48 and 96h, condition A force was 9% and 5% higher but this was not significant. Muscle soreness was not different between conditions at any point. CONCLUSIONS: This preliminary analysis suggests that condition A may attenuate muscle force loss after eccentric exercise, leading to faster recovery. An accelerated recovery phase can potentially aid training intensity and duration as well as overall performance.
