Power training Flashcards
Maximum strength definition
Greatest amount of force exerted
Power definition
equation
Is the ability to exert force quickly
P=W/t
P=F x V
Reactive power definition
Athletes ability to change from an eccentrci to a concentric contraction
Repetitive power definition
Athletes ability to sustain high power output for an extended period of time e.g. 400m sprinter
Motor unit definition
Motor neuron and all the muscle fibres it innervates
Power training dependent on: (5)
Ability to recruit motor units Motor unit synchronisation Rate coding Cross sectional area (CSA) Maximal strength
Rate coding definition
Recruit large FT fibres generate more power
Power load relationship %
30-80% of max
Mid thigh clean pull 1 RM%
60%
Hang power clean 1RM%
70-80%
Power clean 1 rm%
80%
Squat jump 1rm%
0-60%
Bench throw 1rm%
30-60%
Power training keywords (2)
explosion, acceleration
Power training sets
3-5
Power training reps
1-2, 3-5
Power training rest
2-5 min
Physiology of plyos is based on ____ ____ of muslce fibres
reflex contraction
Rapid loading
stretching
____ _____ detects rapid lengthening
muscle spindle
____ _____ sends sensory info to the ___ via ___ ____
Muscle spindle
brain
spinal cord
Mechanisms for enhanced performance (3)
- Enhanced muscle spindle activity and Neuro muscular efficiency
- Desensitisation of GTO
Enhanced muscle spindle activity
faster loading= greater force
Desensitisation of GTO
increases muscle inhibition stimulation threshold
