LIFTING PERFORMANCE IN AQUATIC SPORTS

摘要: Performance in aquatic sports is limited by the ability to maximize propulsive forces and minimize resistive forces. Propulsive may be generated moving body parts or paddles a direction opposite of desired travel, that is, using ‘drag’ ‘Lift’ are perpendicular motion. Thus, if lateral motions used, lift contribute force. Direct quantification drag realistic settings problematic. Therefore, scientists have relied on indirect evidence assess relative importance propulsion sports. The purpose this presentation review relating use three skills. These skills freestyle swimming, flatwater kayak paddling, water polo ‘eggbeater’ kick. implications for technique discussed. Given lack definitive findings, presenter seeks stimulate further investigation into rather than draw conclusions. Since early 1970s, view good swimming involves sculling actions hands preference has predominated. Recent three-dimensional studies contradicted indicate need investigation. Flatwater changed greatly during last 15 years following introduction ‘wing’ blade. wing blade, shaped like an airfoil generate Bernoulli Principle, resulted improved performances. However, based small amount available, it not yet clear whether more Some possible reasons performances kayaking since blade discussed.
