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

What is Speed?

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 m 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

Reactive Strength/Max Velocity

Workout Design 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
