Isotonic Contraction

16. In Activity 9, which weight resulted in the highest initial vlocity of shortening?

17. Explain the relationship between the amount of resistance and the initial velocity of shortening.

18. Explain why it will take you longer to perform 10 repetition lfting a 20-pound weight than it would to perform the same numer of repetition with a 5 pound weight.

Thanks for your assistance

This is because a heavier weight will have a slower velocity for the repetitions, so it will take you longer to repeat the same number of repetitions of a heavier weight.

As the weight of the load increases, the initial velocity to move the weight decreases.
