Strength and power
Strength

Power
● Science and practice of power expression● Force-velocity profiling● Classification of training means● Volume and intensity guidelines● 4 Phase progression for power development
Strength defined
Strength is simply the body’s ability to apply muscular force against an external source of resistance e.g. gravity, opposing player, the ball, friction, air resistance etc.
Louie Simmons:
“Strength matters. It’s why women don’t compete with men. It’s why we have weight classes. And it’s why you can’t weigh 130
fucking lbs and play in the NFL.”
It’s that man again
● To create movement we have to apply forces and create impulse
● Greater force in the same time = greater impulse and momentum change
● A stronger athlete is usually a better athlete
Strength as a reserve
• You cannot change the demands of the game• You can only change the difference between your
capacities and the demands of the game• Increasing strength directly and indirectly increase the
reserve of key physical abilities on the field• Enables higher outputs during maximal efforts• Reduces intensity of submax efforts relative to max• Lays foundation for more specific qualities• Increases robustness
Strength is important…
• Correlation between relative strength and jumping, sprinting and change of direction ability
• Strength work will even benefit endurance performance• It’s tough to be strong and small (maintenance & development
of LBM)• Psychological benefits
*Correlation strongest with novice performers
Force-velocity curve
● We are training for a rightward shift● Max strength initially raises all points on the curve (bang for $)● Strong correlation between strength and power expression
Strength expression
• CNS is the driver:• Motor unit recruitment (more horsepower)• Rate coding (increase the revs)• Motor unit synchronisation (better engine tuning)
The size principle
• The brain is lazy and always uses the minimal effort to complete the task
• More force and/or velocity:• More motor units recruited in sequential fashion• Fatigue increases CNS output and recruitment
• Recruitment ➡ fatigue ➡ adaptation• You can’t fatigue it if you don’t recruit it
The size principle
This means
• Strength may be trained via:• Force• Speed• Fatigue (failure or close to it)• Any combination of the above
Strength training methods
1. The maximal effort method- 85%+ of 1RM2. The repetition effort method- sub maximal loads lifted
for repetitions at or close to failure3. The sub-maximal effort method- sub maximal loads
lifted for low reps, perfect technique and minimal fatigue (movement efficiency)
4. The dynamic effort method- sub maximal loads accelerated with maximal intent (power section)
On hypertrophy
• Some is helpful (GPP, collisions, connective tissue strength etc.)
• A lot can be counterproductive (energy cost of locomotion & detraction from other training means)
• Not a big relationship to speed and power output
• IMHO let the position pick the athlete
The max effort method
• High intensity loads, low reps, moderate to high sets• % of 1RM- 85%+, <6RM loads• VBT: <0.5ms mean velocity• Prilepin’s chart is a good guide• One exercise- focussed stimulus, managed fatigue• Intensification focus- aim for kg on the bar• Advanced training method, lots of fatigue• Popular schemes: 5*5, 5/3/1, 3*3, waves, APRE etc.
Prilepin’s table
• Additional reps- bar speed slows, technique worsens• Additional sets- bar speed slows, excessive fatigue• Err on the lower end for field sport athletes
The sub-max effort method
• The skill of strength- perfect technique with minimal fatigue
• Low reps, moderate load, high sets• % of 1RM- 70-85%, 6-12RM loads• VBT: 0.5-0.75ms mean velocity• Use Prilepin’s chart• Volumisation/frequency focus- reps under the belt• Good for retention loads/beginners• Can train multiple lifts on a daily basis
Repetition effort method
• Not bodybuilding, but can be useful for LBM
• Moderate to high reps, moderate load, high sets• % of 1RM- 70-85%, 6-12RM loads• VBT: irrelevant! • Useful in-season or with developing athletes• Volumisation/frequency focus- tonnage• Can train multiple lifts on a daily basis• Pick adaptations carefully (intensity first, volume second)
Repetition effort method
Phase 1- technique and work capacity
• General exercises at 70-85% of maximum• Weekly volume or density progression• Deload may not be necessary• Possible to combine multiple lifts• Higher volume accessories• Greater prominence of tranverse/frontal plane work• Accessories serve to address individual weakness
Phase 2- maximal output
• General exercises at 85-100% of maximum• Maximal intent on all reps• Weekly intensity progression• Deload often necessary, particularly in longer cycles• Single lifts advisable• Accessories serve to maximise adaptation of main lift
Phase 3- position specific output
• General exercises at 70-85% of maximum• Maximal intent on all reps• Adjust according to readiness/feel each week• Concentrate recovery resources in SDP• Deload unnecessary, as followed by peaking cycle• Single lifts advisable• Accessories serve to promote balance and retention
Phase 4- realisation of adaptation
• General exercises at 30-40% of maximum• Maximal intent on all reps for time• Adjust according to readiness/feel each week• Deload unnecessary (peaking phase)• Single lifts advisable• Accessories performed according to individual
preference, serve to promote balance and retention
Strength is important… but power matters more
• Stronger correlation between power output and jumping, sprinting and change of direction ability than strength
• Especially under highly specific conditions• Inherent time limits to nearly all sporting actions• Transfer of training necessitates a more specific approach
Dynamic effort method
• Simple approach: max power (40-60% UB, 30-50% LB)• Complex approach: address measured or perceived f/v
weaknesses (Morin)• Specific approach: address positional demands• Use Prilepin’s chart, 95% method or timed sets• Lends itself to ballistics and accommodating resistance
tools

Ballistics & Accommodating Resistance
• Traditional lifts end with zero velocity (deceleration)• Ballistics project the load
• Jump and throw variations, Olympic lifts, pneumatic resistance machines
• Accommodating resistance tools• Bands (overspeed eccentrics & soreness issue)• Chains (noise, cost & logistics)• Manual resistance (technical issues)• Increased load requires more force to maintain
constant bar velocity
Phase 1- technique and work capacity
• General exercises at maximum power output• Weekly volume or density progression• Cement technique, develop work capacity• Measurement of outputs not primary concern
Phase 2- maximal output
• General exercises at maximum power output• Weekly intensity progression• Full rest periods• Measurement of outputs wherever possible• Outputs may also govern volume in developmental blocks
Phase 3- position specific output
• Specialised developmental exercises• Performed in contrast with SST• Weekly attempt to progress intent• Full rest periods• Measurement of outputs wherever possible• Outputs may also govern volume in developmental blocks
Phase 4- realisation of adaptation
• Specialised developmental exercises• Performed in contrast with SST• Near max effort is acceptable• Full rest periods• Measurement of outputs wherever possible• Minimal volume (Readiness = fitness - fatigue)
Specialised strength drills
• What is it you or your position does better than anyone else?
• What are the movement characteristics of that skill?• What are the force characteristics of that skill?• What exercises can you use to raise the weak links in that
skill?
Dynamic correspondence criteria
• Range of movement• Working range of movement• Magnitude and direction of force• Movement velocity• Contact time• Regime of muscular work• Muscles used
