STAY HEALTHY , LIVE LONGER

Tuesday, 19 May 2009 20:31

TUESDAY, May 19 (HealthDay News) -- Getting in shape really does help you live longer, new research says.

People with high levels of physical fitness, called cardiorespiratory fitness, have a lower risk of dying from all causes of death, including coronary heart disease and cardiovascular disease, than people with low levels of cardiorespiratory fitness.

Researchers analyzed data from 33 previous studies that included 102,980 participants and 6,910 deaths from a variety of causes and 84,323 people with coronary heart disease or cardiovascular disease and 4,485 deaths caused by those conditions.

Cardiorespiratory fitness (CRF) was estimated as maximal aerobic capacity (MAC) expressed in metabolic equivalent (MET) units.

Participants were categorized as having low CRF (less than 7.9 METs), intermediate CRF (7.9-10.8 METs), or high CRF (10.9 METs or greater).

Participants with low CRF had a 70 percent higher risk for all-cause death and a 56 percent higher risk for coronary heart disease and cardiovascular disease events than those with high CRF, according to the study, published in the May 20 issue of the Journal of the American Medical Association.

Those with low CRF had a 40 percent higher risk for all-cause death and a 47 percent increased risk for cardiovascular disease than those with intermediate CRF.

The analysis suggest that a minimal CRF of 7.9 METs may be important to prevent mortality from all causes, including coronary heart disease and cardiovascular disease, the researchers wrote.

To have adequate CRF, men around 50 years of age must be capable of continuous walking at a speed of 4 m.p.h. and women at 3 m.p.h.

CRF can be assessed by exercise tolerance testing, researchers said. Still, it's rare for clinicians to consider CRF when evaluating future risk of coronary heart disease.

"It is possible that consideration of low CRF as a major coronary risk factor could be put into practical use in the clinical setting through identification of low exercise tolerance by exercise stress testing or in daily life by the speed at which a person can walk before experiencing exhaustion," the researchers wrote.

The analysis also found that a 1-MET higher level of MAC, which corresponds to 0.6 mile/hour higher running/jogging speed, was associated with a decrease of 13 percent in risk of all-cause mortality and a 15 percent decrease in risk of coronary heart disease and cardiovascular disease.

Creatine Supplements...

So, what is creatine? Our bodies naturally make the compound, which is used to supply energy to our muscles. It is produced in the liver, pancreas, and kidneys, and is transported to the body's muscles through the bloodstream. Once it reaches the muscles, it is converted into phosphocreatine (creatine phosphate). This high-powered metabolite is used to regenerate the muscles' ultimate energy source, ATP (adenosine triphosphate).

Unlike steroids or drugs, creatine is 100% natural and occurs naturally in many foods; therefore, it can never be banned from any sports or international competitions (unless they banned eating meat). Many foods especially herring, salmon, tuna, and beef contain some creatine. However, the very best source of creatine by far is creatine monohydrate because it contains more creatine per weight of material than any other source. Bodybuilding.com sells only high quality 99.9% pure pharmaceutical-grade creatine monohydrate.

Nitric Oxide Supplements

1. What is it and where does it come from?
Nitric Oxide is a free form gas that is produced in the body and is used by the body to communicate with other cells in the body. To produce this gas, enzymes in the body break down the amino acid Arginine.

Nitric Oxide is a molecule consisting of one atom of nitrogen and one atom of oxygen. The production of Nitric Oxide occurs when the amino acid L-arginine is converted into L-citruline through an enzyme group known as Nitric Oxide Synthase (NOS). The chemical process of conversion is shown in figure 1.

Protein Supplements...

High protein diets, like Atkins Diet and South Beach, continue to gain in popularity among many dieters. Some athletes even use these diets and find they lose weight. Depending upon the type of athlete you are and what sort of sport you play, you might want to question the role of the high protein eating plan. Athletes should realize that much of the weight lost on these diets is a result of a decrease in total calories and the water loss that occurs with muscle glycogen depletion. If you perform high intensity or endurance training you probably know that glycogen depletion is one of the reasons athletes 'bonk' or 'hit the wall' in endurance competition. Without enough easy to access energy, in the form of glycogen, we simply run out of fuel.
