Question | Answer |
---|---|
What are arthrokinematics | the motions of joints in the body(joint motions) |
What are biomechanics | A stusy that usese the principles of physics to quantitatively study hoe forces interact within a living body |
The human movement system includes | the skeletal,muscular and Nervous systems |
Planes of motion | sagital,frontal and transverse planes |
Muscle Actions | concentric,eccentric and isometric |
Concentric | developing tension while a muscle is shortening;when developed tension overcomes resistive force |
Eccentric | Developing tension while the muscle is lengthening;when resistive force overcomes developed tension |
Isometric | when the contractile force is equal to the resistive force |
Force | an influence applied from one object to another, which results in acceleration or deceleration of the second object |
Human Movement Science | the study of functional anatomy,functional biomechanicsmotio learning and motor control |
Ground Reaction Force | the force the ground exerts back onto the body through the foot |
GFR-Walking | 1 to1.5 times one body weight |
GFR-Running | 2-5 times ones body weight |
GFR-Jumping | 4-11 time ones body weight |
Length-tension relationship | the resting length of a muscle and the tension the muscle can produce at this resting length |
