If you managed to get a Nintendo Wii this holiday season, make sure you warm up before playing it.  Wii gamers are reporting a more physical workout than they expected to get with the new console.  With some describing it as more vigorous than basketball.  But then that wouldn’t take much.

 …as players spend more time with the Wii, some are noticing that hours waving the game’s controller around can add up to fairly intense exertion — resulting in aches and pains common in more familiar forms of exercise. They’re reporting aching backs, sore shoulders — even something some have dubbed “Wii elbow.”

Nintendo says players who get aches and pains from playing the Wii may need to get more exercise.

 Doctors advice: Stretch out and be sure to take care of any injuries afterwards. “It’s just like athletic play,” says Lana Kang, an orthopedic hand surgeon at the Hospital for Special Surgery in New York City.
