task 7

Question 1

describe the passive stretch curve

Answer 1

obtained when one stimulates muscle (with maximal, single impulses), which are passively stretched with varying loads. determine the relative length of the muscle at rest and the passive stretch in comparison to it with adding 50 g weights repeatedly until 300 g.

Question 2

what happens during isotonic contraction

Answer 2

the muscle tone does not change but the muscle length decreases as a result of muscle contraction elicited by the stimulation.

Question 3

what happens during isometric contraction

Answer 3

the muscle length does not change but the muscle tone increases as a result of the stimulation

Question 4

How to examine the isotonic maximum curve?

Answer 4

Apply supramaximal single stimuli and provide isotonic conditions . Register the muscle length for for different preloads from 0-300 g at steps of 50g
