Coordination of movement

3 important questions on Coordination of movement

Describe the three types of motor units

  • Type S = Slow
Low force, slower contraction speed, highly fatigue resistant
  • Type FR = Fatigue Resistant
Intermediate force, fatigue resistant, fast contraction speed
  • Type FF = Fast Fatigable
High force, fast contraction speed but fatigue in a few seconds

What is the relation between maximal tetanic tension and the contraction time?

The tetanic tension is an inverse function of the contraction time.

Describe the two mechanisms to regulate muscle force

  1. Recruitment of motor units according tot the size principle of Henneman
  2. Summation of force as a function of firing frequency (temporal summation)

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
