What is isometric?
Muscle tension stays constant, no movement or change in angle of joint, maintains posture and stability, controlled by nervous system
What is isokinetic?
Speed of the contraction is constant, same speed, length and tension.
Example of isometric
Downward dog
Example of isotonic
Biceps brachii muscle shortens (Load is moved upwards)
Example of isokinetic
Breaststroke
What do muscles act on to move the body?
synovial joints
