Exercise Physiology Part 1 Quiz: (p.1-2)

What is power influenced by in strength and conditioning?

• Both magnitude of force application and time

• Magnitude of force application only

• Distance

• Time only

What is the work-energy relationship in exercise physiology?

• Power = work / time

• Energy = mass x gravity x height

• Work = force x distance

• Work = time rate of doing work and energy = the capacity to do work

• Lasts more than 2 minutes

• Lasts 9-120 seconds

• Lasts 5 minutes

What is the function of the Gluteus Maximus muscle?

• Knee extension

• Hip abduction

• Hip adduction

• Hip flexion

What is the purpose of the Krebs cycle in energy production?

• Remove hydrogen from macronutrients

• Convert macronutrients into ATP

• Series of chemical reactions

• Transfer of electrons to drive creation of ATP

Which muscle extends the spine in the vertebral column?

• Iliocostalis lumborum

• Quadratus Lumborum

• Spinalis

• Longissimus capitus

What is the metabolic demand formula in exercise physiology?

• Cardiac output x oxygen uptake

• Cardiac output - oxygen uptake

• Cardiac output + oxygen uptake

• Cardiac output / oxygen uptake

Which muscle is responsible for lateral flexion of the vertebral column?

• Spinalis

• Longissimus capitus

• Iliocostalis lumborum

• Quadratus Lumborum

What is the function of the Rectus Abdominis muscle?
