Sexercise? Getting Busy Burns Calories, Study Finds
Even with NBA players still on strike, with fall officially here, there's no shortage of sports starting up, from pee-wee leagues all the way up to the pros. But there are also other athletic forms of competition that gain little notice every year despite a dedicated following. Here we explore some sports that you've likely never heard of (and should probably never attempt). We begin with chess and boxing, together at last in a sport whose name is as unlikely as the combination itself: chess boxing. So the name may not be original, but chess boxing is a singular sport that demands brains and brawn like no other athletic competition. Popular in Germany and the United Kingdom, the game is played with alternating rounds of chess and boxing. Competitors can win by winning the chess game, by knocking out an opponent or by judges' decision at the end.
From the looks of this photo, you might think sepak takraw, a sport native to Southeast Asia, is almost a kind of karate volleyball. And you wouldn't be far off. Played with a ball made of dried palm leaves, sepak takraw is popular in Asia and even started to make inroads in North America in the late-1980s and 1990s. Sepak takraw even has a lot in common with similar team sports more familiar to Western audiences. Like soccer, players pass around a ball using anything but their arms. The game is played on a court about the same size as a badminton court. Two teams of three players gather on each side of a net, trying to keep the ball in play. The rules for scoring are similar to that of volleyball.
Given the hard hits and frequent fights so common in ice hockey, it's difficult to believe that anyone could imagine a more potentially hazardous version of the sport. But with the added element of a potential drowning, underwater hockey makes frozen-water hockey look like child's play. The rules of liquid-water hockey are similar to that of it solid-state counterpart. The difference: Players use wooden or plastic sticks about the size of a banana to push around a metal puck around the floor of a pool. The action is especially exciting for spectators, who can only really see ripples on the surface from the action below.
Dog dancing may be more art than sport. But however you classify what could be one of the surest signs yet of the apocalypse, dog dancing, also known as canine freestyle, combines coaching, discipline and dance. Although it may seem like an amateur pastime, dog dancing is actually a competitive sport with contests held in the United States, the United Kingdom, Japan and other countries with pet owners who have too much time on their hands.

Street luge is a sport that combines the safety concerns of the luge with the gentleness of pavement. Participants lie on what is essentially an enlarged skateboard designed to hold the human frame. Gravity does the rest of the work.

The pastime of the wizarding world of the "Harry Potter" series, quidditch combines magic, athleticism, and a touch of violence. Given the sheer impossibility of the sport, you'd think there wouldn't be a real-life equivalent -- and you'd be wrong. There are enthusiastic fans of the series who just wouldn't let reality or the laws of physics stand in their way. And so, these ambitious muggles created their own version of quidditch that might not have all the magic of the dramatic version but certainly isn't lacking for passion. Founded at Middlebury College in Vermont, the International Quidditch Association has grown in just a few short years to include hundreds of teams with a presence on nearly every continent. The game has the same rules and scoring system as the quidditch from the series, with one big difference: no flying.
You sure won't find a chess board -- or anything resembling a board game -- at the annual Summer Redneck Games in East Dublin, Ga. Instead, you'll find the kinds of athletic events that could only come out of Dixie, including toilet seat tossing, seed spitting, and mud belly flops (pictured here). Competitors at the Summer Redneck Games may not get all the attention or the money or the endorsement deals with Nike. As a matter of fact, many of them probably don't even have shoes. But there's no doubt it takes a special kind of athlete to take home glory at the Summer Redneck Games.
Eukonkanto, a sport of Finnish origin, is a simpler than its name implies. Its English translation -- "wife carrying" -- is right on the money, however. Male competitors race across an obstacle course while carrying a female teammate, who grabs onto her partners neck and back while hanging upside-down. Glory isn't the only prize. For those fortunate enough to take home top honors at the Wife Carrying World Championships in Sonkajärvi, Finland, the winning team earns the wife's weight in beer.
Chopping wood may seem like a tireless chore. But at the now retired Great Outdoor Games, there's a lot more to the timber events than that. From log rolling to tree topping to the hot saw and more, the Great Outdoor Games turned lumberjacks into competitive athletes. Each of the timber events was either a race, as was the case with the team relay or speed climbing, or an endurance event, like logrolling.
Played on horseback, the traditional Central Asian sport known as buzkashi may appear to be an eastern variant on polo. But there is one critical difference: Instead of playing with wooden mallets and a ball, participants use the carcass of a cow or goat. Each team consists of 10 players, five of which are in play at any given time. Players score by dragging a carcass across the opposing team's goal line. Given the fact that the game is played with dead animals, it should come as no surprise that the participants can play rough when competing against one another.

Does sex count as exercise? Good news: It might.
A new study finds that, in young people, sex burns an average of 4.2 calories a minute for men and 3.1 calories a minute for women. That intensity is moderate, the researchers reported online Oct. 24 in the open-access journal PLOS ONE. In other words, sex is better exercise than a walk, but not quite as good as a jog.
"These results suggest that sexual activity may potentially be considered, at times, as a significant exercise," the researchers wrote.
Sex as exercise?
Whether sex gets to count as a workout is a long-debated topic. A popular myth holds that a typical session of sex burns between 100 and 300 calories, but no one has ever directly measured the calories burned.
A few brave couples have had sex for science, however. Famed sex researchers William Masters and Virginia Johnson observed couples having sex and noted that heart rates reached as high as 180 beats per minute. For comparison, between 85 and 119 beats per minute count as moderate-intensity exercise for a 50-year-old. (Infographic: How Many Calories Am I Burning?)
In 1984, a study of 10 intrepid married couples published in the journal Archives of Internal Medicine used heart rate and blood pressure monitoring, a fast-responding oxygen gas analyzer and electrocardiography to determine that, for men, self-stimulation increased heart rate by 37 percent. Man-on-top sex increased it by 51 percent.
One problem with these studies, however, is that the couples had to get busy in the lab, hooked up to wires and tubes — imagine the difficulty of reproducing a, ahem, typical sex session. Fortunately, new technology provides a way around this monitoring problem.
Using a wearable armband called SenseWear, University of Montreal researchers tracked the energy expenditures of couples as they had sex in their homes. The researchers recruited 21 heterosexual couples ages 18 to 35, choosing to focus on young people because energy expenditures vary widely across age.
Each person first completed a 30-minute moderate-intensity treadmill workout to provide a baseline measure of their calorie expenditure during exertion. They were then sent home with armbands and instructions to have sex four times over the course of the next month while wearing the sensors.
The SenseWear bands use accelerometers, temperature sensors and galvanic skin response sensors to come up with an accurate measurement of calories expended. Galvanic skin response refers to an increase of electrical conductivity that occurs when a person sweats.
Let's get physical
The recorded sex sessions lasted for an average of 24.7 minutes, with the shortest lasting 10 minutes and the longest stretching out over 57 minutes. Men expended more energy getting busy than women, even after controlling for men's greater body mass. On average, a sexual encounter cost men 101 calories, or 4.2 calories per minute. That's compared with 276 calories, or 9.2 per minute, on the treadmill.
Women expended an average of 69 calories during a session of sex, averaging 3.1 calories per minute. Again, the numbers weren't as high as a sweat-it-out session on the treadmill, during which women expended an average of 213 calories, or 7.1 per minute.
Still, the researchers said, people found sex pleasant (duh) and thus might be more likely to get horizontal than to schlep to the gym. Sex may also be a better way to burn calories than housework, though more research is needed: A study released in October in the journal BMC Public Health found that people overestimated how many calories they were burning while sweeping floors and vacuuming.
