 Healthy Lifestyle Changes Increase Telomerase Length by 10%

Methods This follow-up study compared ten men and 25 external controls who had biopsy-proven low-risk prostate cancer and had chosen to undergo active surveillance. Eligible participants were enrolled between 2003 and 2007 from previous studies and selected according to the same criteria. Men in the intervention group followed a programme of comprehensive lifestyle changes (diet, activity, stress management, and social support), and the men in the control group underwent active surveillance ...

 Exercise Rejuvenates the Body

As noted earlier, mitochondrial degradation is a primary culprit in dwindling muscle mass. But recent evidence indicates that exercise can slow down this effect. According to Mark Tarnopolsky, a professor of pediatrics and medicine at McMaster University in Hamilton, Ontario, resistance training activates a muscle stem cell called a satellite cell. In a physiological process known as ‘gene shifting,' these new cells cause the mitochondria to rejuvenate. Tarnopolsky claims that after six mon...

Strength training specifically prompts the body to produce stem cells that repair motochondria, promotes the production of telomerase to maintain DNA, increase lifespan by six to seven years, and improve cognitive function dramatically as we age.

 Put Your Health Above All Else

With your talents and industry, with science, and that steadfast honesty which eternally pursues right, regardless of consequences, you may promise yourself every thing—but health, without which there is no happiness. An attention to health then should take place of evey other object. The time necessary to secure this by active exercises, should be devoted to it in preference to every other pursuit.

 Exercise Increases the Number of Mitochondria in Brain Ti...

Past experiments have shown persuasively that exercise spurs the birth of new mitochondria in muscle cells and improves the vigor of the existing organelles. This upsurge in mitochondria, in turn, has been linked not only to improvements in exercise endurance but to increased longevity in animals and reduced risk for obesity, diabetes and heart disease in people. It is a very potent cellular reaction. [...] Like muscles, many parts of the brain get a robust physiological workout during exer...

A study on mice finds that exercise increases the production of mitochondria in brain tissue in addition to their production in muscle tissue (I dig the term "mitochondrial biogenesis" as describing the benefit).

 The Brain Consumes Lactose During Exercise

Scientists have discovered that lactose, a byproduct of intense muscular activities, can be used to fuel the brain with energy. When glucose, the natural fuel of the brain, is no longer present in sufficient quantities, the cell tissue can “switch” to alternative energy, to prevent any damage to the brain on account of the lack of energy. [...] Consequently, by consuming the lactose in the blood, the brain clears the way for glucose, the main powering substance in the body, to reach the...

This frees up the body's glucose to fuel the muscles in times of high energy demands on the body (Note: This meme must be wrong in using the term "lactose," because that is a sugar that comes from milk. "Lactate" is a byproduct of muscles consuming glucose that fuels the brain while the muscles take energy-precedence).

 A Succinct Definition of Lactate

Lactate is a dynamic substrate with great potential as an energy source in sports drinks. To date, however, the efficacy of adding lactate to these drinks has been sparsely assessed [5,15,16]. Lactate was once considered a metabolic waste but is now recognized as an important energy substrate in the body. Lactate is the main product of carbohydrate metabolism and can be used as a fuel in working muscle cells shuttled to other tissues such as the heart where lactate is fuel [17], or to the liv...

A byproduct of our muscles converting carbohydrates to energy, which appears to serve as a secondary energy source.

 Studies Showing the Benefits of Exercise

Scientists are also encouraged by studies on mice with a certain genetic mutation that makes them age prematurely — complete with graying and thinning fur, cataracts, hearing loss, smaller brains, enlarged hearts, anemia and thin and weak muscles — hallmark symptoms of growing older. To test whether it was possible to slow or reverse the process in these mice, a team led by Dr. Mark Tarnopolsky, a professor of pediatrics and medicine at McMaster University in Ontario, Canada, had the ro...

 The Effects of Aging and How Exercise Counteracts Them

• Motor neurons die, particularly from age 60 onward. This causes connections between muscle fibers to wither — and that, in turn, eventually leads to loss and shrinking of muscle fibers. As a result, muscles get smaller and a person gets weaker, says Sandra Hunter, an associate professor of exercise science at Marquette University in Milwaukee. "Physical activity can offset some of that," she says. "But there is this biological aging process going on — the neurons will die regardle...
