QuestionAnswer
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
