At Massey University in Palmerston North, sports and exercise scientist Paul Macdermid is testing how vibrations effect mountain bike riders. Volunteers such as Steve Stannard are being kitted out with hi-tech equipment to measure things like breath-by-breath VO2, heart rate, and vibrations in different planes, and are then riding uphill on both a road and an off-road track while keeping a steady 80% performance to determine the differences between the two. While it may seem obvious that mountain bike riders would expend more energy riding on the rough terrain of a cross-country track as compared with a road track, if the effects of increased vibrations can be measured and correlated, then steps can be taken to improve the performance of mountain bike racers.
