effects of immobilization
metabolism, duration of immobilization, degree of stretch, fiber distribution, and protein turnover rate are factors of this effect
what is muscle atrophy?
this effect on bones is reduced with immobilization
what is piezo-electric?
this type of contraction activates slow twitch fibers first
what is isometric?
how many steps are there in re-entry to sport
what is 6?
this fiber type will atrophy quicker because they are used to constant stimulation and affererent feedback
what is type slow twitch
this connective tissue decreases with immobilization creating joint stiffness
what is articular cartilage?
this strategy activates fast twicth fibers first
what is electrical stimulation?
this type of training keeps the distal portion still while the proximal moves
what is closed kinetic chain?
this type of fracture will have the biggest decrease in activation due to pressure, pain, priprioception problems, and joint distribution
what is fixated?
this type of protein decreases with immobilization
what is myofibrilar?
this strategy works by myokines and growth hormones
what is cross-education?
in the first 2 weeks after surgery this % of MVC and ROM should be regained
what is 50?
true or false: muscles are faster to fatigue after immobilization
what is false?
this joint position is best to reduce atrophy during immpobilization
what is equal stretch of agonist and antagonist?
this strategy works by activating integrin
what is stretching?
this is the most important factor of velocity specificity in training
what is contraction speed?
this connective tissue increases with immobilization causing stiffness
what is collagen?
muscle metabolism does this with immobiliztion
what is decrease?
this strategy turns on the supplementary motor area and helps with motor control
what is mental imagery?
these strategies should be used 24 hours post surgery
what is isometric contraction, electrical stimulation, and cross education
