Effect of DMG on Maximal Aerobic Power

Purpose: Dimethylglycine (DMG) is advertised to aid in the delivery of oxygen. We examined the effects of DMG on the VO2max of college women. We hypothesized that pre-exercise DMG consumption would increase VO2max. Methods: Ten well-trained college women ingested three, 800mg doses of DMG or a placebo (PLC) on two occasions in a randomized, double-blind fashion. Thirty minutes after the last dose subjects performed a VO2max test. VO2, heart rate, and exercise time were compared. Results: No significant differences were found using independent t-tests in the DMG versus the placebo trials on heart rate (DMG 191.4 7.5 bpm Placebo 191.2 6.1 bpm, p=0.79), VO2max (DMG 48.8 2.6 ml∙kg-1∙min-1 PLC 49.2 2.6 ml∙kg-1∙min-1, 0=0.56), and exercise time (DMG 12.81 42 s PLC 12.84 .45 s, p = 0.81) Conclusion: Based on these results, DMG has no significant effect on improving the endurance of well-trained women.
