The Pretty, Smart People


Why is our group smarter and prettier than other exercise groups? 

We believe that our style of exercise produces the very attractive and popular Middle Distance Runner/ Runway Model physique. But, there is more to it.

Dr Emma Wedgeworth, consultant dermatologist and British Skin Foundation spokesperson, tells us that it's scientific fact that as well as being good for general health, running can also help our skin.

"When we exercise," she explains, "we boost circulation to our skin, increasing oxygen and nutrient delivery, which gives us that immediate post-exercise glow. Enhanced skin blood flow can also help skin cells regenerate and remove toxins more efficiently. All of these changes can help regulate comedogenesis, the pore blockage which is the first stage in acne."

In addition, running - as with all exercise in general - is known to reduce our natural stress hormone cortisol, "which can be pro-inflammatory and make a number of skin conditions worse, including chronic skin conditions such as eczema," Dr Wedgeworth says. Stress is also one of the major triggers for scratching, which is known to make eczema worse. "So managing stress by regular exercise may prevent skin damage from that."

SMARTER:

About three decades of research in neuroscience have identified a robust link between aerobic exercise and subsequent cognitive clarity, and to many in this field the most exciting recent finding in this area is that of neurogenesis. Not so many years ago, the brightest minds in neuroscience thought that our brains got a set amount of neurons, and that by adulthood, no new neurons would be birthed. But this turned out not to be true. Studies in animal models have shown that new neurons are produced in the brain throughout the lifespan, and, so far, only one activity is known to trigger the birth of those new neurons: vigorous aerobic exercise, said Karen Postal, president of the American Academy of Clinical Neuropsychology. “That’s it,” she said. “That’s the only trigger that we know about.”

The other fascinating thing here is where these new cells pop up: in the hippocampus, a region of the brain associated with learning and memory. So this could help explain, at least partially, why so many studies have identified a link between aerobic exercise and improvement in memory. “If you are exercising so that you sweat — about 30 to 40 minutes — new brain cells are being born,” added Postal, who herself is a runner. “And it just happens to be in that memory area.”

Other post-run changes have been recorded in the brain’s frontal lobe, with increased activity seen in this region after people adopt a long-term habit of physical activity. This area of the brain — sometimes called the frontal executive network system — is located, obviously enough, at the very front: It’s right behind your forehead. After about 30 to 40 minutes of a vigorous aerobic workout – enough to make you sweat – studies have recorded increased blood flow to this region, which, incidentally, is associated with many of the attributes we associate with “clear thinking”: planning ahead, focus and concentration, goal-setting, time management.

Getting Higher


Boot Camp Participation is HIGHER. The Basic Training Repetition count is HIGHER. The Paces are HIGHER. The Mileage is HIGHER. Total Fitness is HIGHER!!

The Science behind Elite Group Fitness Training

As kids, we loved to get together to play with our friends. As teenagers, our world revolved around our friends; oftentimes, our friends dictated our choice of activities. As adults, we still enjoy being active with friends, but don’t always feel like we have the time or opportunities to do so. Group exercise provides us with an opportunity to feel young again and be physically active with others.

Endorphins are produced by virtually any vigorous physical activity, but group work appears to enhance the effect dramatically - and there's plenty of evidence that exercise classes meet that description. In a series of studies stretching back more than a decade, University of Saskatchewan professor Kevin Spink has found those who feel a greater sense of "groupness" and cohesion within an exercise class are more punctual, have better attendance and even work harder.

Studies have established why, physiologically, exercising outside improve dispositions or inspire greater commitment to an exercise program. A few small studies have found that people have lower blood levels of cortisol, a hormone related to stress, after exerting themselves outside as compared with inside.

Endorphins get all the attention, but your body also pumps out endocannabinoids, which are a naturally synthesized version of THC, the chemical responsible for the buzz that marijuana produces. The most examined endocannabinoid produced in the body, anandamide, is believed to create a feeling of calmness. Endorphins can be created only by specialized neurons, but pretty much any cell in the body is capable of making endocannabinoids, which means they have the potential to make a bigger impact on your brain. Endocannabinoid production is believed to react more strongly in response to stress as opposed to pain (the stronger endorphin activator). Differentiating between physical stress and discomfort during a run is nearly impossible. Which means the same mechanism that triggers endorphins can also trigger endocannabinoids: a challenging (not killer) workout, running at 70 to 85 percent is optimal in spiking the primary stress hormone cortisol, and producing endocannabinoids.

Serotonin and dopamine are chemicals produced in the brain -- neurotransmitters -- that improve mood and protect against mental health disorders. Serotonin, which is produced by long-term cardio exercise, decreases depression and hostility, and improves agreeable social behavior. Dopamine improves your mood and long-term memory. It stimulates highly pleasurable feelings in the brain and could contribute to what is called "runners high.”
