1
Q

principles of rehabilitation and reconditioning

A
  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
Q

macrotrauma

A

specific sudden episode of overload

3
Q

sprain

A

partial tear of a ligament LPLPLPLP

4
Q

strain

A

tears of muscle fibers TMTMTMTM

5
Q

microtrauma

A

overuse injury

6
Q

difference between macrotrauma and microtrama

A

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

7
Q

process of tissue healing

A

inflamation
repair
remodel

8
Q

treatment goal of inflammation phase

A

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

9
Q

treatment goal of repair phase

A

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

10
Q

treatment goal of remodel phase

A

optimizing tissue function, replacing damaged tissues with collagen fibers.

11
Q

closed kinetic chain

A

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

12
Q

open kinetic chain

A

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

13
Q

exercise options in repair phase

A

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

14
Q

exercise selection for remodel phase

A

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

15
Q

mechanical model

A

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

16
Q

neurophysiological model

A

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

17
Q

muscle spindle

A

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
Q

phase I of plyo

A

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

19
Q

Phase II of plyo

A

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
Q

phase III of plyo

A

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
