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.

Folic acid should be added to bread on a mandatory basis, the Food Standards Agency has advised government. It says the move could cut the number of babies being born with spina bifida by nearly two thirds, as the vitamin plays a key role in foetal development. Women are advised to take supplements before becoming pregnant, but many do not do so, or take them too late.

Research has linked folic acid to a raised cancer risk, but the FSA said the evidence was not convincing. The US and Canada started fortification of bread flour in the late 1990s, and some of the subsequent research has pointed to an increase in cases of bowel cancer. However the Scientific Advisory Committee on Nutrition, which advises the FSA, said this evidence was insubstantial and that any increase in cases could be down to improved screening. It did, however, recommend that those deemed to be at greater risk of colon cancer should receive precautionary advice on taking extra supplements containing folic acid, and that the situation should be monitored.

Unplanned pregnancies

Last month there were calls for all Scottish women to take folic acid – even those not planning a family – after 15 babies were born with the condition since the start of the year.

Folic acid is a synthetic form of folate, a B vitamin found in a wide variety of foods including liver and green leafy vegetables. The body cannot store it, so it must be ingested daily via supplements or folate-rich foods. The vitamin is known to prevent neural tube defects in foetuses, but many women do not take it – in part because pregnancies are often unplanned and can go unnoticed for many weeks.

As well as cutting the incidence of spina bifida, latest research from Canada also suggests it can reduce the risk of congenital heart problems in babies. But while cereal has long been fortified, suggestions that bread should be supplemented have been rejected by those who argue it is tantamount to mass medication. The FSA’s advice has been sent to the UK’s chief medical officer – Sir Liam Donaldson, who is known to be an advocate of fortification. Legislation would be needed however for the move to go ahead.

A spokesman for the Department of Health said: “We will now consider their recommendation for the introduction of mandatory fortification of flour with folic acid alongside controls on voluntary fortification.”

In many countries around the world, convenience has made real solid nutritional food take the back seat and created many problems in its wake.  Fast food, preservatives, and processed foods may create low-cost, long-lasting products that make the act of eating a cinch, but the long-term effects of ingesting these “foods” can be extremely hazardous and even life threatening.

So many people are now trying to watch their weight and eat right.  It is certainly the right thing to do for your health and for the environment, especially if your tastes include organic fruits, vegetables, and grains that promote sustainability in the process.  The problems start, however, when diet is not enough.

Supplementing Your Diet

So you think you’re eating well; you eat three squares a day and still perhaps feel sluggish and unable to get on the right track with your health.  Chances are you are now experiencing deficiencies in vital vitamins and trace minerals that your body was oblivious to when you were consuming processed foods.  Now that you are eating well, your body is trying to tell you that you’re missing something.

This is where supplements come in.

People often don’t realize that taking multivitamins and minerals is often the only way to get these substances into your body.  Over time, our bodies relied on certain things to achieve homeostasis, which included actually ingesting trace amounts of minerals on our foods.  With our focus on cleanliness these days, this is nearly impossible to achieve without supplements.

Help in a Pinch or On the Go

Additionally, it may not be entirely possible to consume all of the vitamins your body needs in raw form without running the gamut of the produce aisle in an attempt to ingest as much as possible.  Finding ways to supplement your protein and fiber intake is also far easier when using supplements and satisfies the need to get some fuel in a fast and convenient manner.

Smoothies and shakes are a great way to get the extra daily requirements in without having to slow down on the busiest of days.  Once your body adjusts to receiving these extra little boosts that it really needs to stay fully operational, you will begin to see and feel the difference.

Of course, no change in diet is complete without proper physical fitness and regular exercise.  Always consult a physician when making major lifestyle changes and try to avoid making abrupt changes, as serious complications can occur.

It seems that Winter is well on its way – not only is it dark and cold outside, but bugs are EVERYWHERE! Even various friends with the strongest of constitutions tell me they feel they are fighting something off, have a tickle in their throat or have families with all sorts of viruses and sniffles. If like me, you have a susceptible toddler (not to mention a personal immune system weakened by pregnancy) going out in public seems like a game of Russian roulette!

There are some things you can do to help protect yourself and your family from the afflictions associated with the cold weather, so here are a few tips: (more…)

Another interesting article on the BBC Health pages today. Here’s an extract….

Low levels of the sunshine vitamin, vitamin D, may contribute to chronic pain among women, scientists believe.

The link does not apply to men, suggesting hormones may be involved, according to a study published in the Annals of Rheumatic Diseases said. The team from the Institute of Child Health in London said studies were now needed to see if vitamin D supplements can guard against chronic pain.

About one in 10 people are affected by chronic pain at any one time in the UK. The causes are not well understood and much of the focus to date has been on emotional factors. Dr Elina Hyppönen and colleagues believe, at least in women, vitamin D levels could play a role in some cases of chronic pain. (more…)
