Questions and Answers

What is the definition of task failure?

  • Inability to perform the exercise or contraction anymore (correct)
  • Decrease in force generating capacity
  • Complete muscle fatigue
  • Reduction in rate of force development

    • During isometric contractions, what does fatigue result in?

  • Reduced force, reduced rate of force development (RFD), and reduced rate of force relaxation (RFR) (correct)
  • Reduced force and reduced power
  • Increased force and increased rate of force development (RFD)
  • Reduced force, reduced velocity, and reduced power

    • What happens to fatigue during concentric contractions?

  • Results in increased force and reduced power
  • Results in reduced force and increased velocity
  • Results in reduced force, reduced velocity, and reduced power (correct)
  • Results in increased force and increased power
