People who received the latest must-have games console for Christmas last year have been urged to do a warm up before they start playing in order to avoid injury.The Chartered Society of Physiotherapy (CSP) has urged players to do "appropriate warm-up techniques" before starting to play their favourite game. This warning follows a report in the New Scientist this week which showed that surgeons who played on a Nintendo Wii before carrying out operations on patients helped to improve their medical accuracy."Playing virtual games like tennis or boxing will contribute to the 30 minutes of exercise you should aim for each day," a spokesperson for the CSP said.He added: "The key to using the Wii safely, to avoid any injuries, is to recognise that it can work areas of the body that might not be used to exercise. People should use some appropriate warm-up techniques before playing one of the more demanding sports-based games."Talk to a qualified doctor now about any health matter on 0906 665 8002.
