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.

As a reasonable proportion of SK Nutrition clients are looking to improve their risk factors in relation to heart disease, through improved lifestyle and eating habits, I thought the following article may be of interest to you.

It is not clear why it’s the case, but it seems that having a sibling with cardiovascular disease (CVD) is bad news for your own odds of developing CVD. It seems that an early shared environment may be a factor, with people developing poor eating or exercise habits in childhood that continue into their adult lives, but further research is needed.

In case you missed the article, here is the link to the BBC’s coverage: BBC NEWS | Health | Sibling link to heart health risk.

Professor David Heber, Ph.D.Taken from “Protein 101” by Dr David Heber, M.D., Ph.D.

It seems everywhere we look someone is promoting a new diet that praises the power of protein. But whether you want to lose or gain weight, or maintain your current weight, the importance of protein goes far beyond physical appearance and muscle building.

A necessity for every BODY

Protein is an important component of every cell in the body. It is an organic compound, composed of 22 amino acids, otherwise known as the building blocks of life. Protein is stored in muscles and organs, and the body utilizes it to build and repair tissues, as well as for the production of enzymes and hormones. Protein also makes it possible for blood to carry oxygen throughout the body. Along with fat and carbohydrates, protein is a “macronutrient,” meaning the body needs relatively large amounts of it. The Institute of Medicine of the National Academy of Sciences has concluded that our daily protein requirements should be 10 percent to 35 percent of our total caloric intake, with men needing slightly more than women. A lack of protein can cause loss of muscle mass, decreased immunity, as well as weakening of the heart and respiratory system. (more…)

A scary video but an important message that I thought worth sharing.

Ahmed Al Haj is only 48 and looks healthy on the outside, yet this Bangladeshi waiter has ended up on the operating table for a triple heart bypass.

As a Muslim, Ahmed does not smoke or drink, but his diet has been rich in ghee, the clarified butter in which many south Asian dishes are drenched. Instead of a healthy pink muscle, his heart looks like a pulsating lump of lard after a lifetime of eating too much saturated fat.

The layer of fat encasing Mr Haj’s heart was so thick the surgeons doing his triple bypass could not see his coronary arteries. Surgeon Shyam Kolvekar from The Heart Hospital at University College London, who performed Mr Haj’s triple bypass, said cases like this were increasingly common and highlighted the dangers of eating too much saturated fat.

Having discovered my all-time favourite website – www.ted.com – this weekend, I thought I’d share one of the many fascinating talks from it.

In a sobering 3-minute talk, Dr. Dean Ornish tracks the dramatic spread of obesity, diabetes and cardiovascular disease around the globe — as people outside the US start to eat, live and die like Americans do. “This may be the first generation in which our kids live a shorter lifespan than we do,” Ornish says. The good news? These trends are preventable and even reversible through diet and exercise.

Click here to watch the short video.

Dean Ornish is a clinical professor at UCSF and founder of the Preventive Medicine Research Institute. He’s a leading expert on fighting illness – particularly heart disease with dietary and lifestyle changes. There are a number of other talks from Dr Ornish on TED.com.
