Explanation:
The lever gets more effective the longer the moment arm of the muscular force is. Fewer muscles are required when efficiency is higher.
Explanation:
True. Muscle force has a more significant mechanical advantage since it has a more extended moment arm than resistive force in a second-class lever.
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).
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.
Explanation:
The sternum, ribs, and vertebral column comprise the "axial" skeleton. The "appendicular" structure includes all the remaining bones in the body.
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?
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.
