Question

TRUE OR FALSE

1. The longer the time tension is exerted, the greater the muscular endurance. *

2. The greatest amount of torque is produced by maximum tension in a muscle that is oriented at a 90° angle to the bone, and anatomically attached as far from the joint center as possible. *

3.The greater the torque a muscle can produce, the greater the movement it will produce on the body’s levers. *

4. When the fibers of a pennate muscle shorten, they rotate about their tendon attachment or attachments, progressively decreasing the angle of pennation. *

5.The fast-twitch fibers have smaller diameter than the slow-twitch fibers. *

6.At maximum velocity, no cross-bridges can form, so no force is generated, resulting in the production of zero power. *

7.The smaller number of cross-bridges results in a larger amount of force. *

8. A high percentage of slow-twitch fibers is advantageous for generating fast movements, and a low percentage of fast-twitch fibers is beneficial for activities requiring endurance. *
