Question 1: What happens when the latent period gets longer?

Answer:

The weight of the load gets larger Question 2: How does the shortening distance change as the load becomes heavier?

Answer:

The shortening distance decreases as load becomes heavier

Question 3: What happens to the muscle when load is increased?

Answer:

If the load is increased, the muscle must generate more force to move it and & the latent period will therefore get longer b/c it will take more time ton

Question 4: When does an isotonic concentric contraction occur?

Answer:

When a muscle generates a force greater than the load attached to the muscle's end. After the muscle tension exceeds the weight of load, an isotonic concentric contraction can begin

Question 5: What happens during isotonic contractions?

Answer:

The skeletal muscle length changes & thus the load moves a measurable distance

Question 6: What does the shortening-velocity refer to?

Answer:

The shortening velocity refers to the speed of the contraction from the muscle shortening while lifting a load.

Question 7: Explain why the latent period becomes longer as the load increases

Answer:

Cross bridges cycle and when the muscle tension exceeds the load, muscle shortening happens. The latent period increases as the weight of the load gets heavier, this is for the necessary force to be generated by the muscle.

Question 8: Describe an isotonic concentric contraction

Answer:

The muscle length shortens as the load moves Question 9: Explain why the shortening load becomes slower as the load becomes heavier.

Answer:

When the weight is heavy, the speed in which the muscle lifts the weight decreases in speed at a slower velocity.Question 10: Explain why it would take you longer to perform 10 repetitions lifting a 10kg weight than it would to perform the same number of repetitions with a 5kg weight

Answer:

because as the weight of the load increases, so does the latent period time and the shortening velocity speeds. With the lighter weight, the muscle is contracted quicker in both latent and shortening velocity speeds.

Question 11: When does the latent period occur?

Answer:

The latent period occurs when there is a rise in muscle tension but no movement or contraction of the muscle.
