CH.11 PLYOMETRIC (REACTIVE) TRAINING CONCEPTS Flashcards
ALSO KNOWN AS JUMP OR REACTIVE TRAINING, FORM OF EXERCISE THAT USES EXPLOSIVE MOVEMENTS SUCH AS BOUNDING, HOPPING, AND JUMPING TO DEVELOP MUSCULAR POWER
PLYOMETRIC TRAINING
TRAINING IN WHICH INDIVIDUAL REACTS TO GROUND SURFACE IN SUCH A WAY THAT THEY DEVELOP LARGER THAN NORMAL GROUND FORCES THAT CAN BE USED TO PROJECT BODY WITH GREATER VELOCITY OR SPEED OF MOVEMENT
PLYOMETRIC TRAINING
REACTION STIMULUS CLIENTS ENCOUNTER DURING PLYOMETRIC TRAINING (GROUND SURFACE)
REACTIVE TRAINING
BEFORE PERFORMING PLYOMETRIC EXERCISE, CLIENTS MUST POSSES ADEQUATE WHAT ?
CORE STRENGTH, JOINT STABILITY, ROM, AND ABILITY TO BALANCE EFFICIENTLY
ABILITY OF MUSCLES TO EXERT MAXIMAL FORCE OUTPUT IN MINIMAL AMOUNT OF TIME
RATE OF FORCE PRODUCTION
EXERCISES THAT GENERATE QUICK, POWERFUL MOVEMENTS INVOLVING EXPLOSIVE CONCENTRIC MUSCLE CONTRACTION PRECEDED BY ECCENTRIC MUSCLE ACTION
PLYOMETRIC (REACTIVE) TRAINING
TO MOVE WITH EFFICIENCY (OR PRECISION), FORCES MUST BE DAMPENED (ECCENTRICALLY), STABILIZED (ISOMETRICALLY), AND THEN ACCELERATED (CONCENTRICALLY)
INTEGRATED PERFORMANCE PARADIGM
FUNCTION OF MUSCULAR DEVELOPMENT AND NEURAL CONTROL
SPEED OF MOVEMENT AND REACTIVE NEUROMUSCULAR CONTROL
3 PHASES OF PLYOMETRIC TRAINING
ECCENTRIC OR LOADING PHASE
AMORTIZATION PHASE OR TRANSITION PHASE
CONCENTRIC OR UNLOADING PHASE
FIRST STAGE OF PLYOMETRIC MOVEMENT, ALSO CALLED DECELERATION, LOADING, YIELDING, COUNTER MOVEMENT OR COCKING PHASE
ECCENTRIC PHASE
PHASE IN PLYOMETRIC TRAINING THAT INCREASES MUSCLE SPINDLE ACTIVITY BY PRESTRETCHING MUSCLE BEFORE ACTIVATION
ECCENTRIC PHASE
STORED IN ELASTIC COMPONENTS OF MUSCLE DURING LOADING PHASE (LIKE STRETCHING A RUBBER BAND)
POTENTIAL ENERGY
PHASE THAT INVOLVES DYNAMIC STABILIZATION AND TIME B/W END OF ECCENTRIC MUSCLE ACTION (LOADING OR DECELERATION PHASE) AND INITIATION OF CONCENTRIC CONTRACTION (UNLOADING FORCE PRODUCTION PHASE)
AMORTIZATION PHASE
KNOWN AS TRANSITION PHASE OR REFERRED TO AS ELECTROMECHANICAL DELAY B/W ECCENTRIC AND CONCENTRIC CONTRACTION DURING WHICH MUSCLE MUST SWITCH FROM OVERCOMING FORCE TO IMPARTING FORCE IN THE INTENDED DIRECTION
AMORTIZATION PHASE
A PROLONGED AMORTIZATION PHASE RESULTS IN LESS WHAT DUE TO WHAT ?
LESS OPTIMAL NEUROMUSCULAR EFFICIENCY FROM LOSS OF ELASTIC POTENTIAL ENERGY
A RAPID SWITCH FROM ECCENTRIC LOADING PHASE TO CONCENTRIC CONTRACTION LEADS TO WHAT ?
MORE POWERFUL RESPONSE
OCCURS IMMEDIATELY AFTER AMORTIZATION PHASE AND INVOLVES CONCENTRIC CONTRACTION RESULTING IN ENHANCED MUSCULAR PERFORMANCE AFTER ECCENTRIC PHASE OF MUSCLE CONTRACTION
CONCENTRIC PHASE (UNLOADING PHASE)
ENHANCES EXCITABILITY, SENSITIVITY, AND REACTIVITY OF NEUROMUSCULAR SYSTEM AND INCREASES RATE OF FORCE PRODUCTION (POWER), MOTOR UNIT RECRUITMENT, FIRING FREQUENCY, (RATE CODING) AND MOTOR UNIT SYNCHRONIZATION
