Vitamin C Doesn't Boost Your Workout
|
TUESDAY, Jan. 11 (HealthDayNews) -- Vitamin C doesn''t pump up your exercise performance, says a University of Colorado study. The findings contradict previous research that suggested ingestion of vitamin C reduced oxidative stress and, therefore, could provide a boost during workouts. The new study found that while vitamin C did reduce oxidative stress during endurance exercises such as running, cycling and walking, neither short-term nor long-term use of vitamin C helped aerobic performance. This was true for both men and women in two age groups -- 23 years old and 61 years old. "We did see a decrease in oxidative stress with large does of vitamin C, but this decrease didn''t improve aerobic abilities either for younger or older subjects," study author Christopher Bell said in a prepared statement. The study appears in the current online edition of the Journal of Applied Physiology. More information The U.S. National Library of Medicine has more about vitamin C.
