! Mel Siff detailed this concept in a more complex, neurophysiologic manner
! “it is vital to remember that all exercise involves information processing in the central nervous and neuromuscular systems, so that all training should be regarded as a way in which the body’s extremely complex computing systems are programmed and applied in the solution of all motor tasks”. ! Supertraining

! Information gathering and interpretation
! Response generation
! Muscle Activation ! Proprioception ! Graded response ! Muscle coordination ! Motor unit synchronization
! Altered responses based on environmental variations
Training presents specific stimuli that can promote improved function in one or more of these factors

! Relatestospecificityoftraining

! The deeper the squat, the less it transfers to jumping and sprinting
! Consider transfer, value, and Stress ! Do squats at different depths have different value?
! Deeper squats = more glute activation ! Caterisano, A, Moss, R, Pellinger, T, Woodruff, K, Lewis, V, Booth, W, and Khadra, T. The effect of back squat depth on the EMG
activity of 4 superficial hip and thigh muscles. J Strength Cond Res 16:428-432, 2002.
! Different stresses at each different range of motion. Variation of stress? ! Qtr squats = greater anterior shear ! Full squats = greater posterior shear
! Schoenfeld, BJ. Squatting kinematics and kinetics and their application to exercise performance. J Strength Cond Res 24:3497-3506, 2010.
! Angles trained?
! Angles overloaded? ! If training loads calculated based on full squat 1RM, loads in quarter squat angles
represent only 60-70% of strength capacity at those angles
Full Squat 1RM Quarter Squat 1RM
172 kg 232 kg
**********JOINT-ANGLE OVERLOAD************
85% = 146 kg 146 kg = 62%
Loads must be calculated based on the 1RM at the depth to be trained!

HOW TO DEVELOP DYNAMIC SPEED &

Overload & Specificity § Force = Strength Training § Power = Plyometrics & Explosive Work § Speed Strength – Weighted Movements § Force Orientation – Mechanics/Technique
ú Possibly the most important….and most often ignored….trainable attribute.
Speed Science § JB Morin, et al (2011) – Definitively showed that
force application technique and the orientation of the force were more important than the total amount of force applied. Horizontal force application was found to be correlated to sprinting speed, but vertical force and total force were NOT.
§ Weyand, et al (2014) – Elite sprinters run differently and have a different force orientation than other runners. Ground contact time, leg speed and GRF are only about 30% greater for elite sprinters compared to normal people, but their speed is 80% greater.
Creating Horizontal Power § Great sprinters cover 1.5 meters on 1st step
§ Foot height is only 12-‐30 centimeters on 1st step
§ Ground contact time is .17 sec on 1st step compared to .08 sec at max velocity
§ Push -‐ Impulses
2/27/17
3
What to Look For
§ Forward Lean § Knee Drive § Positive Shin Angles § Braking vs Propulsion § Ankle Dorsiflexion § Covering Ground
Teaching Cues & Progression
§ 1st step ú Foot poppers ú Wall drills ú Starting stance ú Push, not step
§ 2nd step ú Wait to finish the first ú Drive knee forward ú Push backward
Weighted Sleds § 15-‐20% BW
ú Shown to improve acceleration speed (Alcaraz, et al, Harrison, et al, West et al, Cottle et al, Bolger et al)
§ 45-‐50% BW ú Shown to improve
horizontal force strategies (Kawamori, et al)
§ Short distances § Long rest periods
2/27/17

Improve Neural Efficiency
§ Train acceleration early in the workout
§ Focus on quality § Short distances § Long rest periods § Lots of feedback § Start young § Include football

Unitilateral Leg Strength: Step Up Test
I Prefer This As A Test & Training Because Of The Co-contraction Of Hamstring Due To
The Proximity Of The Foot To The Butt Which Helps Stabilize The Knee And Reduces
Strain On The Patella (R Panariello)
Start With A Low Box And Progress To A Higher Box Height With 4 To 6 InchesIncrements.
Emphasize Eccentric Strength And Control, Go Down Slowly Just Tap The Floor And Come Back Up. Keep All The Load On The Upper Leg. Observe The Support Knee For Any Deviation. You Can Start Training With Just Doing The Eccentric Phase
Squat Vertical Jump Test: Maximum, Explosive And Explosive Speed Strength
Squat Jump Test:
The Athlete Starts With Their Legs Flexed To Position They Want Jump From, And Hands On Hip.
They Hold This Squat Position For 4 Seconds And Jump Straight Up Without Any Further Downward
Movement
To Prevent A Counter Movement The Tester Should Place There Hand Underneath The Athletes Chin
Norms Vary Depending On The Sport, Position & Size Of The Athlete
Male 16-20"
Female 12-16“
For Linear Explosive Strength Use Standing Long Jumps
Male 7’ 6” –9’ 6”
Female 6’ 6”-8’ 6”

Counter Movement Vertical Jump Test: Stretch
Shortening Cycle Complex Height/ Distance
Counter Movement Vertical Jumps The Athlete Starts From Standing Straight
Up, Hands On Hip, Squats Down And Jumps Upward
Measure Rapid Eccentric Over Load Of Extensors. Males Should Improve 15%
To 20%. Females Should Improve 11% To 15%, 4 Inches More Then Static VJ
Male 23-26"
Female 15—20"
You Can Break These Scores Down Further By Size, Sport And Position

Repeat Counter Movement Vertical Jump:Stretch Shortening Cycle Complex (Muscle Elasticity/Stretch Reflex)
MAY BE NOT APPROPRIATE FOR ALL ATHLETES
Hands Must Stay On The Hip For All Four Jumps. They Should Try And Jump As Has High
They Can On The First Jump And As Has High And As Fast Has They Can 2,3,and 4 Jump
Take The Total Distance For 2,3 & 4 Jump I.E. 60"and Divide Total Distance By Time On The
Ground .6 And Reactive Strength Index Score = 100.
Step Close Vertical Jump Test:
Stretch Shortening Cycle Complex (Muscle Elasticity/Stretch Reflex)
Step Close Vertical Jumps, The Ability To Covert The From Linear To

Calf Muscles Very Involved In The ‘Landing-Shock Absorbing’ Phase Of Running, Jumping & CD.That’s The Preliminary Reason For Strengthening Of Calf Muscles, Before The Use Of JumpingExercises To Improve Eccentric Control, & To Avoid Calf Muscle Strains.Y. Verkhoshansky.
For speeds up to 7.69 Yards Per Sec, The Ankle Plantarflexors, Soleus And Gastrocnemius,Contributed Most Significantly To Vertical Support Forces And Hence Increases In Stride Length
The Arch Of The Foot & Achilles Tendon Contribute 30-40% Elastic Energy To High IntensityActivities.

Hurdle Jumps: Stretch Shortening Cycle
Complex (Muscle Elasticity/Stretch Reflex)
For A Linear Test Use 5 Hurdle Jumps Height Depends On The Age And Size Of The Athlete
Start at a height of 60% Of Their Best Vertical Jump
Look For Ground Contact Times Of.17 Or Less
Progress The Hurdle Height Until The Time Becomes Greater The .15
Train At Hurdle Height That The Contact Is Short.
To Long A Contact Time Means Your Not Training Stretch Shortening Cycle Effectively
Single Leg Hurdle Hops: Stretch Shortening Cycle
Complex (Muscle Elasticity/Stretch Reflex)
You Can Also Use A 6-12" Cone For Hurdle Hops Test
Hops Test Should Be Only With A Well Prepared Athlete
Hops: Are Unilateral, Take Off And Landing On The Same Leg
Listen For The Sound Of When They Land. An Athlete Who Use The Stretch Shortening Cycle Efficiently Will Have A Quieter Landing, Than An Athlete Who Is Inefficient Using The Stretch Shortening Cycle
CAUTION

Don Chu Drop & Freeze Pre Test Any Use Of Boxes
In Training Stretch Shortening Cycle Complex: The Beginning Athlete Must First Show The Ability To Land And To Deaccelerate Using
Eccentric Contraction To Control Landing Forces.
Start With A Box 6-8’ Lower Then Their Best Vertical Jump
Minimum Strength Level Require For Test, Squat Body 1.25 Mass x1.
Drop and Freeze
Step Off The Box “Freezing”, The
Downward Movement By Using
Eccentric And Isometric
Contractions. This Can Be
Incorporated In Any Jump.
They Should Stick The Landing & Be In
Athletic Position Ready To Move.
Landing Should Be Soft And Quiet
There Should Be No Buckling Of The
Body & No Inward Or Outward Flaring
Of The Knees
Don Chu In Depth Jump Stretch Shortening Cycle Complex Test Test
(Ploys)Do In Depth Jump From 18” Box. If They Can Equal Their Best Vertical Jump Form 18” Female
Start At 12 “
If They Failed To Equal Best Vertical Jump At 18” Box Don’t Proceed To Next Height
They Need More Maximal Strength Squat Minimum 1.5 Body Mass Progress 2x Body Mass
If They Equal Best Vertical Jump From 18” Repeat Test From 24” Box
If They Equal Their Best Vertical From 24” They Are Prepared To Do In-Depth Training, Has Long
Has the Meet The Strength Requirement
If They Failed To Equal Best Vertical Jump At 24” From Box, Don’t Proceed To Next Height. For
Large Athletes Over 220+ Use 18” Box Height For Test
