| What is Radius? Radius and Hollow are terms often used to describe a figure skating blade. The main effect for a skater of both radius and hollow is mostly on edges and control. Radius, is a measure of the curvature of the ice skating blade from front to back. Radius determines the amount of blade that actually touches the ice. The radius at the front of the blades can be different than the radius toward the back of the blades. The radius at the front of the blades is typically measured in inches and determines blade profile . For instance the most common front profile radiuses are 12", 17" and 27". This front profile radius is where skaters do the majority of the spinning and jumping. The smaller the radius will give more clearance from the toe pick to the ice and a better ability to spin. The larger the radius the flatter the blade and the less clearance from the toe pick to the ice. The radius that is measured toward the back of the blades is commonly measured in feet and is called the rocker. The back of the blades are where most of the gliding, stroking takes place. If you drew a circle with a 7 foot radius and aligned a blade to the inside of that curve, the blade would match the curve. A radius of 8 feet is less curved, or flatter, than a radius of 7 feet. A radius of 8' will give you more speed. A smaller radius of 7 feet, will make you more mobile. For the beginner or petite skater, a 7' radius is fine. |
Прыгать можно и на ширпотребе. Когда я писал про первое поверхностное впечатление, я имел в виду в первую очередь именно вращения. Как мне кажется, именно для вращений они менее удобны, чем традиционные одиночные лезвия. Возможно, на них легче делать твиззлы и т.п. Но — еще раз, по первому впечатлению — для вращений они не кажутся удобными.
