Finishing a marathon is a huge athletic feat, but not everyone who finishes one is in tip-top shape. A new study finds that people who have not trained appropriately and may not be in the best shape could temporarily damage their hearts. The study, presented Monday at the Canadian Cardiovascular Congress 2010 in Montreal, focused on 20 healthy amateur runners who were given exercise, blood and MRI tests six to eight weeks before a marathon, two days after finishing, and some three months later.

You've been dumped by a romantic interest you really liked. You've been passed over for a job by a boss you thought admired you. A group of friends is going out together, leaving you out of their plans. This kind of social rejection prompts your brain to send warning signals to your body that there's been a sudden tear in your personal social fabric, says a new study. Some of those signals you will undeniably feel -- the pain in your gut, the ache in your heart, the lump in your throat.

Whether you're trudging on a treadmill, pedaling on an exercise bike or taking on Roger Federer in a Wii game of Grand Slam Tennis, the machine will probably give you a reading of how many calories are going up in sweat. In fact, no matter what you're doing -- and that includes doing nothing -- you can find a gadget to compute how many calories you're working off. But should you put a lot of weight on these figures? "The short answer is no," says Dr. Chris Cooper, director of the UCLA exercise physiology research laboratory.

Nothing would seem to be more "green" than exercise, which gives off sweat and smell but not pollution. But if you get your cardio on a machine, you're not completely eco-clean unless you use one that doesn't plug into a wall socket, which is at least partially powered by fossil-fuel-burning power plants. Aside from a few categories -- rowing machines, spinning bikes and some high-end self-generating exer-bikes -- there have been no other electricity-free treadmills and ellipticals available until just a few months ago. Here's the first look at the workout world's newest green machines.
