HIGH JUMP An analysis of the approach, takeoff, and bar clearance Ryan Koch & Heather Miller-Koch The Model Model (definition) ● – “A system or thing used as an example to follow or imitate.” ALWAYS HAVE A MODEL ● – Guides athlete development – Structures coaching progression – Provides feedback Our high jump models ● – Derek Drouin (takeoff) – Stefan Holm (bar clearance) – Antonietta DiMartino (complete jump, female) Important Concepts Vector ● – A measurement that has both magnitude and direction – Examples: Velocity ● Acceleration ● Center of Mass ● – A point representing the mean position of the matter in a body or system. Angular Momentum ● – Figure Skater Example Arms out = slow ● Arms in = fast ● Components of the High Jump i. Approach ii. Takeoff iii. Bar Clearance Components of the High Jump i. Approach ii. Takeoff iii. Bar Clearance Approach What is the purpose/goal of the approach? ● – Posture The approach must prepare the athlete for proper take-off positions ● The single most important result of the approach is the athlete's body ● position leaning away from the bar at take-off – Tempo/Rhythm The approach must build toward ● the takeoff – Speed Less critical for younger jumpers, ● but necessary for elite-level heights ● Approach Approach Length ● – A longer approach almost always equates to more speed at takeoff, and too much speed will limit performance, especially for a younger athlete – Common stride counts High School = 8-10 ● College = 8-12 ● Elite = 10-14 ● Approach Approach Phases ● – Straight Generate enough speed so as to not have to over-work the corner ● Generate rhythm ● The initial phase of the high jump approach is among the most ● varied technique in all of track and field; it is very much affected by athlete comfort and preference This is the part of the approach most prone to inconsistencies ● – Corner Run a true corner to generate the desired body lean ● – Cannot be an “L” or anything comprised of straight line segments; this will take the athlete out of the desired body position A quality high jump cannot be achieved without a quality corner ● Components of the High Jump i. Approach ii. Takeoff iii. Bar Clearance Takeoff What is the goal of the takeoff? ● – Add a vertical component to the athlete's velocity Takeoff – in any jump – is the process of increasing the angle of the ● athlete's velocity vector “Convert” or “block” ●
