Exam 5: Biomechanics of Resistance Training

What are the units of measurement of force?

The newton.meter (N.m) is the SI unit for what mechanical quantity?

The center of gravity is an anatomical landmark that is fixed at one point in the body.

Stability of a body is only affected by the size of the base of support and the mass of the body.

Which of the following is an example of a wheel-axle machine in the musculoskeletal system?

A body is balanced if its line of gravity falls outside its base of support.

Explain the concept of friction.

Explain the difference between an ascending and descending strength curve.

At what percentage of a muscle's resting length is the muscle able to produce the greatest contractile tension?

The effectiveness of a muscle's tension is greatest when the muscle's angle of attachment is greater than 90 degrees to the bone on which it pulls.
