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 (2530m)
Mero, Komi & Gregor, 1992
Factors That Affect
Speed
Technical vs. Physiological
Technique & Physiology
Different phases of
sprinting
– acceleration & max
velocity
Strength
– Maximalrelative/absolute
– Reactive-stretchshortening 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 4050m 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 strengthSSC
– 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 lengthrequires 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
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
