Development of Aid Training Equipment for Improving the Short Track Speed Skaters' Ankle Support Ability

As a key of short track speed skating techniques,the reasonable ankle joint angle will be changed into improper position which resulting in worse performance because of the skaters' lacking ability to maintain the ankle at reasonable angle in actual movement.The aid equipments are very rare for Chinese skaters to improve the ankle support ability in dry-land or ice training,so it's is in dire need of any related aid training equipments.According to the ankle biomechanics principle of short track speed skating,the paper designs an aid training equipment of ankle support ability,which structure relates to 3 parts: shoe block,roller and baffle.When a skater has a training on the ice,he may fix the shoe block in the shoe tongue and lace,adjust the link angle of roller and baffle to meet the coach's requirement.The equipment is helpful for the skaters to not only master reasonable ankle angle,but also ensure correct skating technique with better ankle support,thereby it can improve the skaters' skating performance.
