'Hot pants' plan to boost cyclists

With Team GB's medal tally growing on a daily basis, a pair of battery-powered "hot pants" could help track cyclists continue the country's Olympic glory.

The heated trousers, which are being used by Team GB's track sprint cyclists, including triple Olympic gold medallist Sir Chris Hoy, have special heated filaments which help to keep athletes' core muscles warm between warm-up and the start of an event.

Developed by experts from Loughborough University, British Cycling and adidas, the Adipower muscle-warming pants are said to perform a job similar to tyre warmers in Formula 1 racing, keeping the muscles heated in a bid to improve performance.
