resistance exercise Flashcards
key elements x3
strength, power, endurance
resistance exercise
activity in which muscle contraction is resisted by & outside force
functional strength
ability of NM system to produce the appropriate amount of force to accomplish functional tasks smoothly
strength training
space using muscle force to raise, lower, or control heavy load over a short period of time
power training
ballistic movements involving strength + and speed
muscle endurance
the ability of a muscle to contract repeatedly against an external load & resist fatigue over time
endurance training
using muscle force over an extended period of time
overload principle
resistance > metabolic capacity to improve muscle performance
SAID principle
- task-specific training = practice of actual task
reversibility principle
adaptive changes in response to a resistance exercise program are transient
- if you don’t use it, you lose it
- reg. exercising to keep mm
- detraining = 1-2 weeks
type I mm fibers
slow twitch
high resistance to fatigue (postural mm)
type II mm fibers
fast twitch
low resistance to fatigue
hypertrophy
increase in size of mm fibers
- 4 to 8 weeks
hyperplasia
increase # of mm fibers
external stabilization
therapist/equipment
