Vitamin E Protects Against Muscle Damage
MUNCIE, Ind.--In findings presented in late September at an American Physiological Society meeting, vitamin E may protect muscle cell membranes--and ultimately muscles--during resistance training exercises such as weight lifting. Bruce Craig, from Ball State University here, presented a three-week study in which 11 men under the age of 25, who had never weight lifted before, trained with weights. Six of the men took 1,200 IU of vitamin E a day, while the other five took a placebo.
After each subject did three sets of upper and lower body weights, Craig and his colleagues analyzed each man's blood level for creatine kinase, an enzyme that marks muscle damage. It was found that vitamin E supplementation increased creatine kinase levels up to 48 hours after weight lifting. For more information, visit www.the-aps.org.
