1. Starting Aim – development of max horizontal velocity
Achieved by placing body in best biomechanical position to apply force

2. Types of Sprint Starts Aim to develop max impulse
Impulse = Force x Time
Distance between blocks – bullet (<30cm), medium (30-50cm), elongated (>50cm)
Medium – best combination of body position to develop force and time on blocks

3. Pedal Angle/Foot Placement
Stretch Shortening Cycle
Front Block - >45 deg
Front Spikes in ground
Rear Block – low as flexibility allows (c35 deg)
Foot position depends upon pedal height

4. Set Position Shoulders over hands – elbow’s not locked
Hips above shoulders
Flat back – neutral head position
Lower legs c45 degree
Front knee 90 – 110 degree
Rear knee 120 – 135 degree
Body weight evenly on feet and hands
Hold breath/tighten stomach muscles

5. After the Gun Focus on motor task – front arm/rear leg
Hips projecting forwards not up
Arms above parallel
Front arm – forearm lead
Rear arm – straight arm sweep back
Low rear heel recovery
c45 degree take off angle

6. Determining Best Start Position for your Athlete
Fit the biomechanical model
Time to 10m
Changes with strength/growth
