liquid multi-vitamin/mineral would improve anaerobic exercise performance.
Fourteen resistance-trained men performed a 30-second cycle
sprint and one set of squat exercise on 2 separate days before and following
8 weeks of supplementation with either a liquid multi-vitamin/
mineral or a placebo. Heart rate, perceived exertion, blood lactate, peak
and mean power, and rate of fatigue were determined for all tests. No
differences were noted for any variable (P > 0.05). When controlling for
presupplementation values, however, a decreased rate of fatigue was
noted for both exercise tests following the multi-vitamin/mineral supplementation.
These data suggest that in resistance trained men consuming
a nutritionally sound diet, supplementation with a liquid
multi-vitamin/mineral does not favorably impact most anaerobic exercise
performances. Such supplementation, however, may result in a
minor decreased rate of fatigue. It appears that, in terms of improved
short duration anaerobic exercise performance, supplemental micronutrients
may not be efficient ergogenic agents for well-trained individuals
consuming an adequate diet
