Explains why I enjoy running to Dark Side of the Moon. Now if you'll excuse me, I'm off to get a black light for beside the treadmill.

"Phys Ed: What Really Causes Runner’s High?
By GRETCHEN REYNOLDS

For decades, endorphins have hogged the credit for producing “runner’s high,” that fleeting sense of euphoria and calm that many people report experiencing after prolonged exercise. Who among us, after an especially satisfying workout, hasn’t thought, “ah, my endorphins are kicking in.” Endorphins are the world’s sole celebrity peptide.
Endorphins first gained notoriety in exercise back in the 1980s when researchers discovered increased blood levels of the substance after prolonged workouts. (Endorphins, for those who know the word but not the molecules’ actual function, are the body’s home-brewed opiates, with receptors and actions much like those of pain-relieving morphine.) Endorphins, however, are composed of relatively large molecules, “which are unable to pass the blood-brain barrier,” said Matthew Hill, a postdoctoral fellow at Rockefeller University in New York. Finding endorphins in the bloodstream after exercise could not, in other words, constitute proof that the substance was having an effect on the mind. So researchers started to look for other candidates to help explain runner’s high. Now an emerging field of neuroscience indicates that an altogether-different neurochemical system within the body and brain, the endocannabinoid system, may be more responsible for that feeling.
In a groundbreaking 2003 experiment, scientists at the Georgia Institute of Technology found that 50 minutes of hard running on a treadmill or riding a stationary bicycle significantly increased blood levels of endocannabinoid molecules in a group of college students. The endocannabinoid system was first mapped some years before that, when scientists set out to determine just how cannabis, a k a marijuana, acts upon the body. They found that a widespread group of receptors, clustered in the brain but also found elsewhere in the body, allow the active ingredient in marijuana to bind to the nervous system and set off reactions that reduce pain and anxiety and produce a floaty, free-form sense of well-being. Even more intriguing, the researchers found that with the right stimuli, the body creates its own cannabinoids (the endocannabinoids). These cannabinoids are composed of molecules known as lipids, which are small enough to cross the blood-brain barrier, so cannabinoids found in the blood after exercise could be affecting the brain.
Since that 2003 study, a flurry of research has been teasing out the role that endocannabinoids play in the body’s reaction to exercise. In some of Dr. Hill’s work, for instance, rats treated with a drug that blocked their endocannabinoid receptors did not experience the increase in new brain cells that usually accompanies running, suggesting that a well-functioning endocannabinoid system may be required for cognitive improvements from exercise. Other researchers have found that endocannabinoids may be what nudge us to tolerate or enjoy exercise in the first place. In an experiment published last year, groups of mice were assigned either to run on wheels or sip a sweetened drink. Running and slurping sugar previously were identified as pleasurable behaviors in animals. Now the researchers saw that both activities lit up and sensitized portions of the animals’ endocannabinoid systems, intimating that the endocannabinoid connection may lend both exercise and dessert their appeal.
But perhaps the most telling experiment was published last year by researchers in France who had bred mice with no functioning endocannabinoid receptors. Mice usually love to run, but the genetically modified animals, given free access to running wheels, ran about half as much as usual. Although the full intricacies of the endocannabinoid system’s role in motivating and rewarding exercise is not yet understood, it seems obvious, the researchers say, that the cannabinoid-deprived mice were not getting some necessary internal message. Typically, the endocannabinoid system “is well known to impact onto central reward networks,” the authors write. Without it, exercise seemed to provide less buzz, and the animals didn’t indulge as much.
Whether this accumulating new science establishes, or ever can establish, definitively, that endocannabinoids are behind runner’s high, is uncertain. As Francis Chaouloff, a researcher at the University of Bordeaux in France and lead author of the genetically modified mouse study, pointed out in an e-mail, rodents, although fine models for studying endocannabinoid action, “do not fill questionnaires to express their feelings related to running,” and runners’ high is a subjective human experience. Still, endocannabinoids are a more persuasive candidate, especially given the overlap between the high associated with marijuana use and descriptions of the euphoria associated with strenuous exercise. One recent review article described them: “pure happiness, elation, a feeling of unity with one’s self and/or nature, endless peacefulness,” and “inner harmony.” Ahhhh."

I remember near the end of one of my runs quite a while ago, Shine On You Crazy Diamond, from Wish You Were Here came on the ipod and I thought how surprised I was that it was such a good song to run too (not your typical upbeat melody). This might explain it. :wink:

When I listen to music when I run (which isn't often) I usually go with mellow stuff rather than upbeat stuff. Grateful Dead works best for me, but I do specifically remember one run listening to Roger Waters' "In the Flesh" live album and thinking it was perfect.

Only 5K at recovery pace this morning. Had to keep it short so I coould get home in time for Mrs McD to get out for her run before I had to leave for work.

Way to go Marg! That's awesome. Hopefully, the trend will continue. :D

Rest day today for me. I'm still focusing on strength and short runs until I can stabilize my left knee through strength improvements. Hopefully, I can finally get a handle on my ongoing knee and hip issues. I'm starting to feel more positive about it.

Happy Friday Maniacs!

It's really snowy out there.... I'm planning 5k and hoping I don't slip on any black ice. Guppy did 10k for the first time last night, and he was so stoked about doing it in under 60 mins that he called me on his phone from the end of the street during his warm-down, just because he HAD TO TELL SOMEONE. It was great to see him having something to smile about.

And I have a new running-partner-in-the-making: Ruby, the 11-week-old Labradoodle. Apparently, I can't take her on a 5k run until she's close to a year because running with her too early is bad for her joints, but you'd never know it from how she was running in the snow on our "walk" this morning!

We all need a little something positive in our lives, and I need it now more than ever, so, for me, a nutty little puppy is good for the soul.

When I left for the gym at 6:15AM it wasn't snowing (and there was nothing new on the ground), but when I left the gym at 8AM it was starting to come down... Snow, snow, stay away! :evil:

Ran 3.7 miles (~6K) in 36 minutes. About 5 minutes into my run my lower legs (from just above my knees to my ankles - basically, whatever skin on my legs was exposed) became really itchy! It was actually quite painful and distracting. :? It eventually subsided, but it took at least 10 minutes to go away. I did have little red marks on my skin, but it didn't really look like a rash, more like just "flushing" skin. Weird.

Got up early and ran 2hrs on the treadmill in the garage. Put incline at 7% for the whole run. Watched a movie to keep me company. Getting ready to pack the car and head to TO with my family and see my sis.

Yah! puppy!! awesome DLS!

and Yah! Marg and Nancy!

Last night - got over to the Y and did a run/walk on the treadmill of 5.1k. slowly getting back - all is well. Today - plan to walk home from work - but it's freaking frigid here (currently -26) -so it might be another trip to the Y instead.
Race Hard. Race Happy.
