1

principles of rehabilitation and reconditioning

1. healing tissues must not be overstressed
2. the athlete must fulfill criteria before moving to the next phase of treatment
3. must be based on clinical and scientific research
4. must be adaptable to the indiviuals needs
5. rehabing is a team-oriented process

2

macrotrauma

specific sudden episode of overload

3

sprain

partial tear of a ligament LPLPLPLP

4

strain

tears of muscle fibers TMTMTMTM

5

microtrauma

overuse injury

6

difference between macrotrauma and microtrama

micro is overuse (micro=small, small injury develops over time) marcro is a sudden injury (big injury all of a sudden)

7

process of tissue healing

inflamation
repair
remodel

8

treatment goal of inflammation phase

to prevent disruption of a new tissue, cscs should prescibe excersies that are indicated and not contraindicated

9

treatment goal of repair phase

to prevent excessive muscle atrophy and joint deterioration cscs should add low-load stresses, promote collagen snthesis

10

treatment goal of remodel phase

optimizing tissue function, replacing damaged tissues with collagen fibers.

11

closed kinetic chain

more functional that open, squat, advantage: increased joint stability and functional movement patterns

12

open kinetic chain

isolation of one muscle machine leg extension open (you have to open the lever before you use the machine)

13

exercise options in repair phase

submaximal isometric, isokinetic and isotone exercise, balance and proprioceptive training

14

exercise selection for remodel phase

joint-angle-specific training, velocity-specific muscle activity, closed and open kinectic chain excersie proprioceptive training activities

15

mechanical model

elastic energy in the musculotendinous components is increased with a rapid stretch and then stored

16

neurophysiological model

the potentiation of the concentric muscle action by use of the stretch reflex, muscle spindle plays a role

17

muscle spindle

proprioceptive organs that are sensitive to the rate and magnitude of a stretch, when a quick streetch is detected, muscle muscular activity relexicely increases

18

phase I of plyo

eccentric
action: stretch of the agonist muslce
physiological event: elastic energy is store int he series elastic component and muscle spindles are stimulated

19

Phase II of plyo

amortization
action: pause between phases I and III
physiological event: type Ia afferent nerves synapse with alpha motor neurons
alpha motor neurons transmit signals to agonist muscle group

20

phase III of plyo

concentric
action: shortening of agonist muscle fibers
physiological event: elastic energy is released from the series elastic component
alpha motor neurons stimulate the agonist muscle group
