Wheel pulley made of polyurethane elastic impact on the joint

Roller skating, also known as roller skating and roller skating, is a sport in which special shoes with rollers are used to glide on a hard court. Modern roller skating is divided into five categories: extreme roller skating, speed roller skating, pattern roller skating, leisure roller skating and freestyle roller skating.

As a very popular sport, roller skating is not only the entertainment and excitement of extreme sports, but also a very important reason is that roller skating has a strong security. In a recent study by the University of Massachusetts, USA, an astonishing finding was made that the impact of in-line skates on the joints is about 50% lower than the impact of running on the joints. This is mainly due to the fact that the pulley is not the same as the running, the wheel is rotated when the roller is stepped, the elasticity of the wheel made of polyurethane is very small to the joint, so the elderly and the children are also suitable for this sport. Equipment, the risk of injury after a fall is very small.
