Lab 8 - Length-Tension and Force-Velocity

Question 1

As the joint angle is increased in single joints movements, differences in force production and rate of force development appear due to:

Answer 1

disparities in sarcomere properties

Question 2

Actin and myosin filaments require a certain amount of “………..” to contract with ……… force.

Answer 2

overlapping, optimal

Question 3

Optimal angle of elbow and knee:

Answer 3

approx. 100 degrees

Question 4

Mechanistically, the speed of ……….. determines the number of ………… formed, which ultimately affects the amount of force produced by a contraction.

Answer 4

contractions, crossbridges
