L-Arginine Benefits “Over Age 50 Sports Participants
Antioxidants and L-Arginine Demonstrate Benefits for Active “Over Age 50” Sports Participants
New Research On How Antioxidants, Carotenoids, Amino Acids and Other Nutrients Provide Benefits For Boosting Energy & Endurance.
Dietary Supplements Containing Arginine May Boost Athletic Performance for Active People Over Age 50 Reports A New Study.
The supplemention of key antioxidants including vitamins C and E, folic acid anlong with the amino acid L-Arginine was associated with a 17 per cent increase in the anaerobic threshold, defined asthe amount of physical work done before lactic acid begins to accumulate in the blood, according to findings published in the Journal of the International Society of Sports Nutrition.
“The loss of exercise capacity with age often results in a reduction in physical fitness and more rapid senescence,” explained lead researcher from the University of California, Los Angeles. “A dietary supplement that increases exercise capacity might help to preserve physical fitness by optimizing performance and improving general health and well being in older people.”
The UCLA researchers recruited 16 men with an average age of 57.6 were randomly assigned to one of two groups. One group received the supplement combination while the other received placebo for three weeks. A stationary cycle was used to analyse changes in the anaerobic threshold.
At the end of one week of supplementation the researchers noted a 16.7 per cent increase in the anaerobic threshold in the supplementation group, which was maintained until week three, where a 14.2 per cent increase on baseline values was obtained. In the placebo group, however, no significant changes were recorded .
Commenting on the potential mechanism of action, the researchers focussed on nitric oxide (NO), a molecule involved in many physiological processes, is produced from arginine and inactivated by oxygen free radicals. Supplementation with arginine and antioxidants, the researchers proposed a supporting of the NO system in the cyclists.
“This study indicated a potential role of L-arginine and antioxidant supplementation in improving exercise performance in elderly,” they concluded.
The study was supported by a US National Institutes of Health (NIH) Nutrition and Obesity Training Grant.
Antioxidants will be the focus of the upcoming NutraIngredients “Antioxidants” 2010 Conference in Brussels. Topics ranging from testing to building the science to supporting health claims will be addressed by a range of international experts.
