Module 2 Flashcards
Why is evolution important to sport and exercise
It explains why humans move as we do
How much and what kinds of PA are humans built to perform?
Many different types - eg running, climbing, playing but there is no universal exercise prescription
To what extent are humans also adapted to be physically inactive?
Trade off energy utilisation between PA and reproduction
Why do most humans avoid PA when it is so good for you?
Perceived by some as unpleasant or wasteful use of energy and society often marginalises PA
What is torque?
The turning effect
What is the torque equation
T = F x r
What does r stand for?
Moment arm
A greater torque is dependant on what?
The greater the moment arm, the greater torque can be produced
The best form of exercise to “burn” fat energy stores is:
Prolonged, medium intensity
What type of symmetry do humans and other mammals exhibit that allows them to move purposefully and economically?
Bilateral
Which method of measuring two compartment body mass (FM and FFM) is more reliable?
Dual Energy X-ray Absorbtiometry (DEXA or DXA)
Which one of these is NOT an evolutionary adaptation that favours endurance running?
Arched feet
Mobile shoulder
Relatively hairless
Inner ear
Mobile shoulder
Fat secretes what?
Chemicals
Fat metabolises what?
Sex hormones
Fat is a valuble source of what in the body
Energy/fuel
