As you can tell by all those But so has the number of studies examining whether consistent endurance racing is healthy. Recent research has raised alarms about the potential for plaque buildup and scarring in the heart in some long-distance runners.

Yet other studies have suggested that when marathoners get heart disease, they may be able to weather it better than non-runners.

It can be relaxing and a stress reliever at times. I find it having as much emotional benefits as physical. The roots of today's modern marathon reach back to the legendary Greek story of the messenger Pheidippides. He ran the distance from Marathon to Athens, about 25 miles, to announce "Nike! And most of the stories say he collapsed from exhaustion after his announcement. Fast forward a few thousand years and, depending on good temperatures and local climate, running season always is in full swing somewhere.

Inabout 25, runners finished marathons in the U. Forty years later, inmore thanpeople had. Peter McCullough, chief of cardiovascular research at Baylor Heart and Vascular Institute in Dallas, has completed 54 marathons, one in every state. But he stopped inafter he said research showing the potential dangers made them not worth the risk.

He'd like to see more research, such as a widespread registry of athletes involved in endurance sports and eventually a clinical trial that includes MRI results. McCullough was part of the study that used MRIs to identify the long-distance runners whose right atrium and ventricle dilated immediately after a marathon and up to 24 hours later.

It also included blood tests that showed an elevation in biomarkers that are indicators of heart stress and injury. A smaller subset, he estimates about 1 percent, could be prone to scarring.

Myocardial fibrosis, or scarring of the heart, can lead to heart failure. A study published in on triathletes showed that 18 percent of the male participants, those who trained and competed the most, had more heart scarring than the other athletes.

Meyer, who has finished 16 marathons tries to keep a daily running streak going, even if it's a few miles a day. He said federal guidelines of at least minutes of moderate-intensity exercise a week or at least 75 minutes at a vigorous intensity "are reasonable and promote heart health for the long-term.

He pointed to a Stanford University study published in that focused on runners and non-runners in their 50s. Researchers tracked them for more than two decades. At the beginning of the study, the runners ran an average of about four hours a week. After 21 years, their running time declined to an average of 76 minutes a week, but they were still seeing health benefits. Nineteen years into the study, 34 percent of non-runners had died compared with 15 percent of runners.

David Sabgir, a cardiologist with Mount Carmel Health Systems in Columbus, Ohio, said he doesn't want studies that apply to one segment of hardcore long-distance runners to dissuade others from getting into exercise. InSabgir founded Walk with a Doca health program that brings doctors and patients together to walk in their communities.

It's now at sites in 25 countries. Sabgir, who has run about 10 marathons, was on a 4-mile run with friends recently and they agreed about the many other benefits. The power of exercise can be miraculous.

Then the researchers split the group into two sets of mice: one that would run for five hours and one that would remain sedentary. Soon after their five-hour run, the rodents in the first group displayed far less anxious behavior than the sedentary set when exposed to a so-called dark-light box test. Similarly, mice in the running group had a higher tolerance for pain than those in the sedentary group, as measured by their tendency to jump or lick their paws when placed on a hot plate.

Finally, the researchers performed these same experiments on mice that were given endocannabinoid and endorphin antagonists—molecules that block cannabinoid and opioid receptors in the brain, respectively. The endorphin antagonists did not significantly affect results, but mice treated with endocannabinoid antagonists and mice genetically engineered to lack endocannabinoid receptors were still anxious and sensitive to pain despite having run for hours.

But this side effect is not exclusive to running. However, the high emerges only after a significant effort.

Why does such a reward exist? Researchers like biologist Dennis Bramble and paleoanthropologist Daniel Lieberman watch his TEDxWilmingtonWomen Talk on dopamine have hypothesized that the neurochemical state which makes running gratifying may have originally served as a reward to keep early humans hunting and gathering. David Raichlenan anthropologist at the University of Southern California, was familiar with the idea that natural selection favored traits that allowed humans to run.

A skeleton that makes running easier is not enough to create an endurance athlete. What would make early humans willing to exert so much effort? If anything, humans seem predisposed to conserve energy. Such a neuro-reward would have to do two things: Relieve pain and induce pleasure. But Raichlen had in mind another candidate, a class of brain chemicals called endocannabinoids.

These are the same chemicals mimicked by cannabis or marijuana. And many of the effects of cannabis are consistent with descriptions of exercise-induced highs, including the disappearance of worries or stress, a reduction in pain, the slowing of time and a heightening of the senses.

Earlier research hinted that exercise might trigger a release of these chemicals, but no one had ever documented it during running. So Raichlen put regular runners through treadmill workouts of differing intensities. Before and after each run, he drew blood to measure endocannabinoid levels.

Walking slowly for 30 minutes had no effect, nor did running at maximum effort. Why did jogging increase endocannabinoids, but walking slowly and running at an exhausting pace did not?

Raichlen speculates that our brains reward us for exercising at intensities similar to those used for hunting and foraging two million years ago. If that is true, then natural selection should have rewarded other animals who hunt or scavenge in similar ways.Second wind is a phenomenon in distance running, such as marathons or road running as well as other sportswhereby an athlete who is out of breath and too tired to continue suddenly finds the strength to press on at top performance with less exertion.

The feeling may be similar to that of a " runner's high ", the most obvious difference being that the runner's high occurs after the race is over. Heavy breathing during exercise is also to provide cooling for the body. After some time the veins and capillaries dilate and cooling takes place more through the skin, so less heavy breathing is needed.

The increase in the temperature of the skin can be felt at the same time as the "second wind" takes place. Documented experiences of the second wind go back at least years, when it was taken to be a commonly held fact of exercise.

A second wind phenomenon is also seen in some medical conditions, such as glycogen storage disease type V. When non-aerobic glycogen metabolism is insufficient to meet energy demands, physiologic mechanisms utilize alternative sources of energy such as fatty acids and proteins via aerobic respiration. Second-wind phenomena in metabolic disorders such as McArdle's disease are attributed to this metabolic switch and the same or a similar phenomenon may occur in healthy individuals see symptoms of McArdle's disease.

Muscular exercise as well as other cellular functions requires oxygen to produce ATP and properly function. This normal function is called aerobic metabolism and does not produce lactic acid if enough oxygen is present.

During heavy exercise such as long distance running or any demanding exercise, the body's need for oxygen to produce energy is higher than the oxygen supplied in the blood from respiration. Anaerobic metabolism to some degree then takes place in the muscle and this less ideal energy production produces lactic acid as a waste metabolite. If the oxygen supply is not soon restored, this may lead to accumulation of lactic acid. This is the case even without exercise in people with respiratory diseasechallenged circulation of blood to parts of the body or any other situation when oxygen cannot be supplied to the tissues involved.

Some people's bodies may take more time than others to be able to balance the amount of oxygen they need to counteract the lactic acid. This theory of the second wind posits that, by pushing past the point of pain and exhaustion, runners may give their systems enough time to warm up and begin to use the oxygen to its fullest potential. For this reason, well-conditioned Olympic-level runners do not generally experience a second wind or they experience it much sooner because their bodies are trained to perform properly from the start of the race.

The idea of "properly trained" athlete delves into the theory of how an amateur athlete can train his or her body to increase the aerobic capacity or aerobic metabolism.

Why does running give you a high? A look at the science

A big push [ clarification needed ] in Ironman Triathlon ten years ago introduced the idea of heart rate training and "tricking" one's body into staying in an aerobic metabolic state for longer periods of time.But we always want it—and more of it.

The desire to live was possibly their motivation to run and run fastand the feel-good brain chemicals released when they did so may have helped them achieve the speed and distances required, says David A.

RaichlenPh. The greater the endorphin surge in these brain areas, the more euphoric the runners reported feeling. Get It: Push yourself hard, but not too hard.

Endorphins are painkillers produced in response to physical discomfort, says Matthew Hill, Ph. Kamphoff, Ph. Hooking up with others could also help: An Oxford University study reported that rowers who exercised together significantly increased their endorphin release compared with solo rowers.

When you are on your own, consider wearing headphones : Research shows that listening to your favorite music may spike endorphins. With 9-hour single-charge battery life and expansive sound, these will sit securely in your ears while running.

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, Hill says. 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.

Get It: 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.

Raichlen says that running at 70 to 85 percent of your age-adjusted maximum heart rate is optimal in spiking the primary stress hormone cortisol, and producing endocannabinoids. So prerace jitters could have a payoff. However, chronic stress can dull this effect. That may be one reason why Cecilia J. Hillard, Ph. We mentioned before that working with a partner may help you out.Or maybe you are brand new to running yourselfand you have heard others talking about it.

Most of us imagined a moment where you feel invincible. You could run with the fastest elites and keep up. You could run for hours and hours without feeling any fatigue. Even non-runners are at least peripherally aware that going for a run boosts your mood, leaving you feeling energized and euphoric. Boecker et al. By injecting ten runners with a slightly radioactive tracer compound designed to bind to endorphin receptors in the brain, Boecker et al.

A 3D radioactivity detector pinpointed the locations where the radioactive tracer was being absorbed in the brain at rest, and again after a two-hour run. That is, the more endorphins in their brain, the happier and more energized the runners felt! Work by P. Sparling and colleagues at the University of California — Irvine suggests that a class of chemicals called endocannabinoids are involved, too. In a study published in the journal Cognitive NeuroscienceSparling et al.

Unlike endorphins, endocannabinoids do cross the blood-brain barrier, so they are easier to measure. Sparling et al. A study even found that an exercise program was just as effective as prescription anti-depressants in patients with major depressive disorder.

This suggests that doing cross-training when you get injured is a good idea not just to maintain your physical fitness, but to maintain your mental well-being too. Running is great, but you can get a similar exercise high from long, continuous aerobic exercise of any type.

Rather than having easy days and hard days, a lot of runners end up running hard days and harder days. Running faster can help in a time crunch, but you are putting yourself at risk of overtraining, and when that happens, your days of enjoying running may be a long time away.

By setting aside a few runs each week to be easy, you will find you enjoy those runs more even if you are soreand this will increase those endorphins for after, and you will run faster on your harder days, increasing the feel good factor on those days too! Those easy days are a great time to get together with friends to catch up. Rather than paying for a meal out, you could meet for a run.

If you are running easy enough, you will be able to have a full conversation, and before you know it, your run will be finished, and you can pat one another on the back for a job well done.Please understand that our phone lines must be clear for urgent medical care needs.

As you hit your stride, your body releases hormones called endorphins. And though endorphins help prevent muscles from feeling pain, it is unlikely that endorphins in the blood contribute to a euphoric feeling, or any mood change at all.

Research shows that endorphins do not pass the blood-brain barrier. That relaxed post-run feeling may instead be due to endocannabinoids — biochemical substances similar to cannabis but naturally produced by the body. Exercise increases the levels of endocannabinoids in the bloodstream, Linden explains. Unlike endorphins, endocannabinoids can move easily through the cellular barrier separating the bloodstream from the brain, where these mood-improving neuromodulators promote short-term psychoactive effects such as reduced anxiety and feelings of calm.

Understanding just how physical activity benefits your heart can be strong motivation to get moving to get moving more. Here's what to know. Exercise may also produce new brain cells in certain locations through a process called neurogenesis, which may lead to an overall improvement in brain performance and prevent cognitive decline.
