06_Fundamentals of Biomechanics

What principle is the resistance to change in motion?

• force-motion

• force-time

• inertia

• range of motion

What is the ability to main control of joint/body position by resisting forces?

• balance

• stability

• mobility

• base of support

Which principle indicates the optimal timing of muscle activation and segment rotations is dependent on the movement goal?

• coordination continuum

• segmental interaction

• optimal projection

• spin

What period of the qualitative movement diagnosis involves identifying strengths and weaknesses and the source of errors?

• preparation

• observation

• evaluation/diagnosis

• intervention

Consider the downward phase of a pull-up. The elbow is ​ (a)   , the motion is produced by​ (b)   , ​ (c)   muscle actions are occurring , and the active muscle group is the​ elbow​ (d)
