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.”

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.

Average 50-something fitter than 25-year-old, study claims You may have seen the results of the latest Herbalife research in the press over the last few days. According to the study of 4,000 British adults, 50-somethings eat less calories, exercise more and eat less junk than people half their age.

Here is the coverage from the Daily Telegraph:

Researchers found the average 25-year-old consumes over 2,300 calories a day, exercises only three times a week and munches on 12 types of junk food a month. But the typical 50-year-old has only 1,990 calories each day, does at least four forms of exercise and treats themselves to just one piece of junk food each week. And while those in their mid-20s have three takeaways a month, the older generation have only one.

The study, commissioned by global nutrition and direct selling company Herbalife, quizzed 4,000 Brits on their diet and lifestyle. Neil Spiers, Herbalife’s Regional Vice President, said: “The results of the study will be surprising to most as it’s natural to think that the younger you are, the fitter you are. It seems many young people are making the mistake of underestimating the benefit of a more balanced, holistic approach to diet and lifestyle. It’s great to think that the older generation are showing the youngsters the way when it comes to healthier living.”

The nationwide research of 16-80 year olds quizzed them on their health and exercise habits. It found the over-50s are more likely to walk as much as they can during the day – to the shops or with the dog – while those in their 20s tend to drive everywhere. But when it comes to excuses for not exercising, over a third (36 per cent) of 25 year olds blame not having enough time, compared to 22 per cent of over-50s. The research found 70 per cent of Brits see themselves as healthy – exercising for 27 minutes a day, at least three times a week, opting to go for a walk, run, cycle or gym. A quarter of Brits polled cycle to see friends or go to the shops, and 70 per cent take the stairs instead of the lift. Nearly four in 10 walk to the train station or to work in a bid to keep fit.

The study also found the average Brit believes they are overweight by nine pounds. Over a quarter of the population are currently on a diet – with the ‘low fat’ (30 per cent), ‘low carb’ (14 per cent) and ‘detox’ (eight per cent) diets being the most popular. And they would wish to lose 13 pounds for them to be their ideal weight.

The study also highlighted the lengths people will go to in order to hide their flab. Nearly a quarter have fibbed about the amount they eat, one in five has lied about their weight and 12 per cent have cut labels out of clothing which revealed their real size. A cheeky 16 per cent have turned to slimming aids without telling anyone and seven per cent have uploaded misleading pictures on Facebook.

And 30 per cent have ‘binge dieted’ to fit into a dress or to look good in a bikini in time for a holiday.

Very interesting reading, and not wholly suprising, judging from the conversations I’ve had with some of my clients.

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.

Older people with lower than average vitamin B12 levels were more than six times more likely to experience brain shrinkage, researchers concluded. The University of Oxford study, published in the journal Neurology, tested the 107 apparently healthy volunteers over a five-year period.

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