Multi-stiffness thigh support for the 2012 Olympic sailors

Abstract

Magic Marine and TU Delft worked together to create a new innovative hiking pad that effectively reduces the pressure on the thighs. The key design factors have been a reduction of pressure, (larger pressure spread), leg support and a comfortable contact areas. Hiking is one of the most demanding activities during a race. With wind speeds over 8 knots, 29-94 percent of the total race time is spend hiking. Hiking causes a lot of injuries, especially in the thigh area. The pressure on the leg influences the sailors performance while it causes muscle fatigue, inner tissue damage and overall discomfort. The Olympic thighpads consist of four layers; a supportive lining, protective layer, pressure reduction layer and connection layer. A - The inner lining is constructed without seams, a soft top layer and smooth edges, all to reduce friction and leg deformation. B - A canvas layer protects the battens from sticking into the leg. C - The tapered glassfibre battens effectively reduces pressure by spreading it over the entire leg surface. D - The outer lining supports the thigh. The pads are connected to the suit by Velcro, keeping them securely in place during the race. The Olympic pad will improve the sailors hiking endurance while providing optimal comfort and keeping all focus on the race.
