HURDLE SPRINT Applying Theory into Practice EUROPEAN HORIZONTAL JUMPS AND HURDLE SYMPOSIUM NOVEMBER 10-12, 2017 FALUN, SCHWEDENNovember 10-12 2017 Falun, Sweden— RRüdiger Harksen, National Coach DLV Presentation prepared by: Rüdiger Harksen Presentation to: UKA Date: November 29th
General comments on speed • Genetically determined • Neurophysiological quality • Speed is the product between stride-length and - frequency • Maximum-strength,speed and technique are a dynamic unity • Muscular dysbalances have a negative impact • Submaximal motions promote submaximal patterns in the brain • Speed can only be learned through specific exercises (conformity with competition performance!!)
Biomecanical correct – individual solutions tTendency to stride lenght in sprinting
This is where the crucial difference between sprint and hurdle sprint begins !
Features of hurdle- sprinting • The hurdles on thelane (height) • The givengaps (distances) • The resulting (sprint)- dilemmasituation • The givenrhythms, optimal path-lengths • The necessitytosprintwith high horizontal speed all the time
Requirements for hurdle sprinting • Constant change of stride length and stride- frequency • Constant change of motion amplitude of arms and legs • Constant change of braking phases and phases of acceleration
Key requirement • The athlete should be able to sprint with different mixing ratios of stride frequency and stride length
Hurdle sprinting • Compared to flat-sprinting a specific nature of sprinting has to be developed • The specific hurdle sprinting can not only be developed through flat-sprinting methods!!! • The fundamental task is the combination of between-hurdle-sprinting (frequency drive) and effective hurdle clearance Consequences for training methodology

Trajectory of centre of mass over hurdle is dependent on: Position (height) at last ground contact take-off angle take-off speed Hurdle clearance Ballistic trajectory is determined after take-off to hurdle ! J.May 2011

Fundamental understanding: Hurdle Clearing AND Sprinting between hurdles
Aims of Technique Training Stability of hurdle clearance Constancy regarding to distance to hurdle, flight time and brake time Combination of hurdle-clearance and between-hurdle sprinting as technical basic quality Stability through variability of movement tasks

Different influence of technique Slighter lift of COM of women Fast female flat sprinters have advantages No changes in hurdle height (female) Same discipline but different ! ! ……. 7 or 8 strides to the first hurdle Consequences
Technical Aspects - The shuffle The basic principles in sprint mechanics are the same, execution is much different. Shufflers keep the same angles as sprinters, except everything is lower. Arm carriage is lower, hands are lower, knee lift is lower, heel recovery is lower Smooth transition to third step Keep the ankles flexed, no rotations
Core stenght – stabilisation • Optimize stride pattern • More feed power • Improve working with arms Improvement ideas shuffle
Hurdle – specific Sprinttraining • Frequent sprints over low hurdles • Combination Rhythms • Flying Sprints (given stride - patterns) • Mixed programms • Overspeed – programms • Contrast – programm • One leg ( non cyclic) – sprint • Stick Drills

Issurin)“ • Development ofabilities not at the same time • (e.g.) • Accumulation 3-4 weeks(e.g. aerobiccapacity, max.strenght) • Transition 2-3 weeks(specific) • Realisation 1-2 week • Working with residual effects…..
