Question 1

principles of rehabilitation and reconditioning

Answer 1

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

Question 2

macrotrauma

Answer 2

specific sudden episode of overload

Question 3

sprain

Answer 3

partial tear of a ligament LPLPLPLP

Question 4

strain

Answer 4

tears of muscle fibers TMTMTMTM

Question 5

microtrauma

Answer 5

overuse injury

Question 6

difference between macrotrauma and microtrama

Answer 6

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

Question 7

process of tissue healing

Answer 7

inflamation
repair
remodel

Question 8

treatment goal of inflammation phase

Answer 8

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

Question 9

treatment goal of repair phase

Answer 9

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

Question 10

treatment goal of remodel phase

Answer 10

optimizing tissue function, replacing damaged tissues with collagen fibers.

Question 11

closed kinetic chain

Answer 11

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

Question 12

open kinetic chain

Answer 12

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

Question 13

exercise options in repair phase

Answer 13

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

Question 14

exercise selection for remodel phase

Answer 14

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

Question 15

mechanical model

Answer 15

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

Question 16

neurophysiological model

Answer 16

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

Question 17

muscle spindle

Answer 17

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

Question 18

phase I of plyo

Answer 18

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

Question 19

Phase II of plyo

Answer 19

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

Question 20

phase III of plyo

Answer 20

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
