Speed Development Steve Blocker
Introduction • Why Important? • What is speed? • Limiting Factors • How to improve • Technique • Training methods • Periodization
Importance of Speed • Improving all around performance • Possible difference maker • Taking performance to higher level
Terminology • Speed: ability to achieve high velocity or stride length x stride frequency • Speed Endurance: Metabolic capacity to maintain performance (Conditioning) • Ability to repeatedly accelerate (6+s bouts)
Terminology • Speed Strength: ability to apply force rapidly- Rate of Force Development (RFD) • Special Endurance: sport-specific exercise-relief patterns • Drive Phase: initial acceleration phase approximately 30-50m • May be shorter for non-track sprinters
Terminology cont’d • Max Velocity Phase: occurs as the athlete achieves maximal velocity or “top end” speed • Occurs at approximately 40-50m for elite sprinters • Occurs earlier in non-track athletes (25-30m) • Mero, Komi & Gregor, 1992
Factors That Affect Speed Technical vs. Physiological
Technique & Physiology • Different phases of sprinting • acceleration & max velocity • Strength • Maximal-relative/absolute • Reactive-stretch-shortening cycle (SSC) • Rate of Force Development (RFD)
Importance of Technique • Maximize efficiency of movement • Minimize flight time • Minimize ground contact time • Results in optimal stride length and stride frequency Faccioni
Acceleration-General Concepts • Explode from start position • Accelerating as rapidly as possible • Stride length emphasized • An emphasized horizontal displacement
Common Problems-Acceleration Phase • Athlete stands up too early • First stride is too long/short • “Skating” action in initial steps
Acceleration Technique • Acceleration Phase • Maximize arm/knee drive • Emphasize horizontal displacement • Tucked chin with eyes focused up • Forward lean • References
Acceleration Drills Push-Up Starts Resisted Sprints Hill Running Sprints to 10/20/30/40m from a 3-pt start
Maximal Velocity-General Concepts • Occurs at approximately 40-50m in elite sprinters • Attempt to maintain maximal velocity as long as possible • Stride Frequency emphasized
Common Problems-Max Velocity Phase • Over striding • Breaking forces • Rotational movement • Arms cross mid-line of body • Heel Strike • Lordosis • Arched back
Max-Velocity Technique • Emphasize “rotary” running action • Keep relaxed • Maximize stride frequency • “Chin to Pocket” (Shoulder ROM)
Physiological Aspects • STRENGTH • Maximal absolute/relative • Reactive strength-SSC • RFD
Physiological Aspects • Accelerate quickly • Reach a high velocity • Greater level of force production (strength) • Apply force as fast as possible (RFD)
Max Strength • Get Strong!!! • Maximize force output • Elite sprinters can minimize ground time w/out reducing stride length-requires leg strength • Mero, Komi & Gregor 1992
Reactive Strength • Plyometric Training • Improves reactive strength • Improves rate of force development • Bounding/Box Jumping
Workout Design • Train for speed/agility early in session/week • Least amount of fatigue • Greater risk of injury • Poor kinematics/technique Plisk, 2000.
Periodization • 4-8 week mesocycles • USAW Level I • Base, Volume, Unload, Peak • 1-3 days/week • Volume depends on: • Sport • Position • Time of training year
Training Session • Begin with a dynamic warm-up • Slow & general exercises • Dynamic & specific • Opportunity to teach technique
Speed Training Methods • Varied pace sprints ins & outs • Bounding & plyometrics • Fliers-sprints from on the fly • Push up sprints-acceleration phase • Sprints from 3-pt start position
Conclusions • Keep it simple • Specific • Progressive • Scientific • Do Research
