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.

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.

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…)

Obesity can increase the risk of Alzheimer’s disease by up to 80 per cent, researchers said today. Cutting the prevalence of obesity in the population could help prevent people progressing to the stage they suffer dementia, they added.

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

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.
