The highest possible tension can be achieved if all possible cross-bridges are formed prior to stimulation. Explanation: To produce the strongest possible contraction when needed, it is important that a resting muscle be stretched to an optimal length, but not too far. The relationship between resting length and the ability to generate tension is called the length–tension relationship. References Classification eBook & Resources Section: 11.04 ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
