Abstract: The purpose of this study was to test the effectiveness of vitamin B6, B9, B12 supplement on perceived muscle soreness (MS) to an acute bout of eccentric exercise (EE). Twenty (aged 22.70 ± 1.94 years) healthy volunteers were randomly assigned to either a treatment or placebo groups. All volunteers were prescreened prior to being accepted as a subject. The subjects were instructed to ingest the pills for 4 weeks prior to the EE and for the next four days. All subjects arrived in the morning, resting MS were assessed and then the EE (4 sets of 12 repetitions of elbow flexing with their non-dominant arm). MS were also obtained immediately after the EE, and 2, 6, 24, 48, 72 hrs post-EE. MS increased over time independent of assessment method (palpation, flexion, stationary) and treatment. MS peaked at 48 hrs post exercise independent of treatment in both groups. The data indicated that four weeks of pre-supplementation and continued treatment after EE with vitamin B6, B9, and B12 had no significant effect on the perceived muscle pain compared to placebo treatment.
