Anaerobic Exercise HGH Link

I love this stuff. A recent study published in the British Journal of Sports Medicine may help explain what I have been saying for quite some time here: that exercise stimulates the natural production of growth hormone (the very same HGH we just wrote about yesterday). But it’s the type of exercise that makes all the difference. And this further confirms something else we’ve been saying: that it’s short intense bursts that work the best.

Study Finds Exercise Prolongs Lifespan

A study published Tuesday in the online edition of the American Heart Association’s journal Circulation suggests that frequent exercise can reduce the risk of death in men.

To examine the link between fitness and mortality, Veterans Affairs (VA) researchers gathered fitness data on 15,660 male VA patients undergoing treadmill testing for various medical reasons. The men, who had an average age of 60, where then assigned to one of four groups based on their level of fitness.

According to the results, mortality risk directly correlated with fitness level, with men in the highest fitness category being the least likely to die when compared to their less fit counterparts. For example, across the eight year study period, 44% of the men in the least fit group died, compared to 30% in the moderately fit group, 15% in the highly fit group, and 8% in the very highly fit group.

The Hype Over Human Growth Hormone

A lot of questions hit the MDA doorstep about HGH, Human Growth Hormone, and with good reason. It’s been touted in some circles as a bottled fountain of youth among other grandiose claims. Countless companies have jumped on that bandwagon, peddling worthless products with HGH labels.

We love to take on the propagandists and snake oil sales industries, and today will be no exception. Shall we begin?

The Basics of HGH
The natural HGH coursing through your body right now is, indeed, a perfectly remarkable anabolic hormone. It’s produced by the pituitary gland throughout life, but the levels gradually decline with age. The hormone is key for children’s growth and the health of the body’s organs. It stimulates the growth of muscle, bone and cartilage and enhances immune function. HGH is prescribed for children who are abnormally short in stature and for adults with diagnosed pituitary deficiency.

Study Finds Fitness Best Determinant of Future Cancer Risk

A study in the most recent edition of Obesity for the first time finds that fitness is more important than fatness in decreasing cancer mortality in men.

For the study, researchers from the not-for-profit Cooper Institute in Dallas tracked 38,410 men who completed a comprehensive baseline physical examination at Cooper Clinic in Dallas that included a maximal treadmill exercise test and measures of body mass index (BMI), percent body fat, and waist circumference. The men were then followed for an average of 17.2 years, during which 1,032 deaths from cancer occurred.

According to the researchers, there was a direct correlation between all measures of adiposity (body fat) and cancer mortality, with leaner men registering a significantly lower risk of cancer mortality than their fatter counterparts. In addition, the researchers also found a strong inverse relationship between cardio-respiratory fitness level and cancer mortality, with less fit men having a higher risk of cancer mortality than their fitter counterparts.
