Principles Of Human Movement Flashcards
Length tension relationship
The length at which muscle can produce the most tension
Force couple
Muscles moving together to produce movement
Reciprocal inhibition
Agonist (prime mover) contracts while antagonist (oppose prime mover) relaxes to allow movement
General adaptation syndrome
How the body responds to stress
Phase ?
Initial response to exercise 2-3 weeks
Alarm phase
Phase ?
Body adapts to stimuli, progressive improvement 4-12 weeks
Adaptation phase
Phase ?
Body no longer tolerates demand of training, adaptations may halt, overtraining syndrome risk increases
Exhaustion phase
SAID
{Specific Adaptation to Imposed Demands} principle (principle of specificity)
The type of stimulus placed on the body determines expected physiological outcome
“Weight and movement placed on body”
Mechanical specificity
“Specific exercises using different speeds”
Neuromuscular specificity
“Energy demand placed on body”
Metabolic specificity
The overload principle states that to…
Create physiological change, exercise stimuli must be at a greater intensity level than body is used to receiving
Concentric
Produces tension while SHORTENING to overcome external resistance
Isometric
Produces tensions whole MAINTAINING constant length
Eccentric
Produces tension while LENGTHENING
