Absolute Angle
Branch of mechanics that describes the motion of a body without regard to the forces that produce that motion
Kinematics
______ is described as a change in length while force remains constant
Creep
These are 2 neurologic strategies to increase muscle force production
Rate Coding and Recruitment
This type of muscle allows for increased force production due to it’s large CSA
