chpt 7 Flashcards
(22 cards)
dynamic excercise
an activity that causes the muscle to contract and shorten
adaption
the systematic application of excercise stress sufficient to stimulate muscle fatigue
isokenitic exercise
type of exercise in which a machine is used to control speed of contraction
motor unit
a motor nerve
prehabillitation
trying to prevent injuries before they occur
rehabillitation
process of restoring function through progrmed exercise
slow twitch fiber
fiber in motor unit that requires a long period of time to generate force
fast twitch fiber
fiber in motor unit that produces quick and forceful contractions
static stretching
gradual, slow stretching of muscle
cardiorespieratory conditioning
activity that puts an increased demand on the lungs, heart, and other body systems
proprioceptive neuromuscular facilitation
combination if relaxing and contacting muscles
atrophy
weakens and wastens away muscle
circut training
6-10 strength execises one after another
hypertrophy
an increase in sizebof muscle
isometric
activity that causes tension in muscle but does not shorten
overload
progressive outwork on muscles at controlled rate
preaseaon conditioning
program begining 6-8 weeks
reversibility
process of muscle atrophy due to dissue, imoblization.or starvation
specificity
ability of particular muscle group to respond to targeted training
stretching
moving joints beyond normal range of motion
progressive resistance
type of training until muscles work they reach their capacity
manual resistance
form of dynamic exercise using partner
