Question 1

Which of the following doesn't represent a particular kind of muscle action?

Accepted Answer

Plyometric

Answer

Explanation:
The term "plyometric" refers to a particular workout style that uses the stretch-shortening cycle to enable the rapid generation of peak force. Which of the following doesn't represent a specific kind of muscle action?

Question 2

A muscle that "agonists"...

Accepted Answer

…is primarily responsible for a given movement

Answer

Explanation:
...is mainly in charge of a specific movement. The "agonist" is the muscle most directly responsible for moving. The "antagonist" muscle is the one that can inhibit that movement. A "synergist" is a muscle that indirectly aids in movement.

Question 3

Meaning of Distal...

Accepted Answer

Further from the trunk

Answer

Explanation:
More distant from the trunk. Distal refers to how far away from the trunk a physical component is (relative to another body part). For instance, the elbow is "proximal" when compared to the wrist yet distal when compared to the upper arm (closer to the trunk).

Question 4

The longer the moment arm of muscle force when working with levers...

Accepted Answer

…the less force needed to overcome the resistive force

Answer

Explanation:
The lever gets more effective the longer the moment arm of the muscular force is. Fewer muscles are required when efficiency is higher.

Question 5

Which position on a barbell curl by an athlete has the most extended moment arm of resistive force?

Accepted Answer

At the midpoint of the exercise

Answer

Explanation:
The resistive force (the barbell) is at its most significant horizontal distance from the fulcrum at the halfway point of the activity (elbow). At this point in the range of motion, the moment arm of the resistive force is the longest.
