The prevalence of multivitamin use has increased in the United States among nearly every population. The CDC estimates that 40-55% of Americans consume either a dietary or multivitamin supplement daily. Previous research has suggested minimal physical performance benefits among individuals following a multivitamin supplementation (MvS) period in several populations. However, no research exists focusing solely on the potential psychological benefits of MvS.

PURPOSE: To determine the potential psychological benefits from a MvS period among an aerobically untrained college aged population.

METHODS: Twenty-four college students (20.9±2.6yrs) were divided into three groups (placebo, multivitamin, control) and asked to perform a six minute bout of moderate (60%VO2max) followed immediately by a two minute bout of high (85%VO2max) intensity exercise on a cycle ergometer. Perceived exertion scores were recorded every two minutes for three sites (legs, chest/breathing, overall) using the OMNI-RPE Scale. Following a daily three week supplementation period, the participants repeated the six minute bout of exercise at 60% and two minute bout 85% VO2max and RPE was again determined at all three sites. Comparisons of RPE values between the three groups were measured using repeated measures one-way ANOVAs.

RESULTS: No significant differences existed between the RPEs of the three groups at: Legs at two (p =.704), four (p =.813), six (p =.903), or eight (p = 1.000) minutes; Chest/Breathing at two (p =.457), four (p =.457), six (p =.438), or eight (p =.286) minutes; Overall at two (p =.222), four (p =.786), six (p =.838), or eight (p =.386) minutes.

CONCLUSION: Neither the multivitamin nor the placebo group perceived the post-supplementation exercise bout to be easier compared to the control group at any RPE site, time, or intensity.
