Same Length: Pushing agains and inmoveable object
Same Resistance: Use of free weights
Same Tension: Machines which eliminate sticking point
The muscles exert force, SHORTENS
The muscle exerts force, and lenghtens
Exerts force, but there is NO change in length.
Males/Females have the same
Muscle that contracts concentrically to accomplish a movement
Oposite action to the prime mover muscle, ads balance
Movement in some joints, others remained fixed. (I.e wrists/arm curl)
Is at that bone which remains stationary
Is at that bone which moves durning the same movement
Fast Twitch Fibers
Responsible for ANAEROBIC enery production.
Slow Twitch Fibers
Responsible for aerobic energy production.
the natural, inactive state of a muscle is termed relaxation. When a muscle is conditioned, even in a state of relaxation, one can detect a certain amount of firmness
1) the frequency of nerve impulses
2) the number of motor units that are activated
3) the synchronization of nerve impulses
Factors of Force Production:
muscles become stronger as they are systematically subjected to progressively heavier workloads. This is the principle of...?
a) the tissues to recover
b) positive physiological adaptations to take place
Why is recovery time important?
. Lifting should take 1 ½ secs., while lowering should take 3 secs. ie 10 reps = 45 secs.
How long should controlled movement be?
Range of Motion, Work = Force x Distance
What is R.O.M, and what is the formula?
