Arginine Helps Older Cyclists Improve Performance

Avid cyclists over the age of 50 had an improvement in their performance after taking arginine supplements for three weeks, according to a study just published in the International Society of Sports Nutrition.

“As people age, their exercise capacity may decline – leading in turn to a decline in overall fitness that can impact health,” noted Luigi Gratton, MD, vice president of medical affairs at Herbalife.

A group of 16 male cyclists, aged 50 to 73 years, were randomly assigned to receive either the supplement (Niteworks; Herbalife International, Los Angeles, CA) containing 5.2 grams of L-arginine, or a look-alike placebo and instructed to continue with their usual cycling regimen over the three week study period. After three weeks, those taking the supplement had an increase in their anaerobic threshold – the point at which lactate begins to accumulate in the blood, leading to fatigue.

“Arginine is involved in the production of nitric oxide in the body,” notes Gratton, “and nitric oxide has been associated with the improvement of exercise performance through its beneficial effects on the vascular system.” As people age, production of nitric oxide declines, so the researchers believed that arginine supplementation could support the production of nitric oxide and enhance performance.

The anaerobic threshold of the study subjects was assessed both before and after the three week study period. In those receiving the supplement, their anaerobic threshold increased by 16.7% after one week, and held steady during the three weeks, whereas those in the placebo group experienced no change. “This indicates a potential role for arginine in improving exercise performance in older subjects,” said Gratton, “and improved performance could mean better fitness and healthier lives.”

Niteworks is available to ship now from our online store, where you will also find further articles & product information:

NOTE: The study, conducted at UCLA and funded by Herbalife, used Herbalife’s original formula Niteworks. The current product has a slightly different formula, although no changes were made to the active ingredients.

Niteworks was created based on research conducted by Lou Ignarro, Ph.D., who received the Nobel Prize in 1998 for his work on nitric oxide. Ignarro is a member of the company’s Scientific and Nutrition Advisory Boards.

Another interesting article from the BBC Health News webpages today: A vitamin found in meat, fish and milk may help stave off memory loss in old age, a study has suggested.

Some studies suggest two out of five people are deficient in the vitamin. (more…)

Those who are underweight also have a raised risk, suggesting keeping a healthy weight is important. (more…)
