| 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 |
