QUESTION 1 OF 2
Which PNF technique uses alternating isometric resistance to encourage holding a position?
A. Rhythmic initiation
Check answer
Have another look.
Rhythmic initiation helps teach a movement sequence, progressing from passive assistance toward active performance.
Best answer: D. Rhythmic stabilization
Rhythmic stabilization challenges holding a position using alternating isometric resistance.
What this tests: Match a PNF technique to its purpose.
B. Contract-relax
Check answer
Have another look.
Contract-relax combines a contraction with a subsequent stretch for a mobility purpose.
Best answer: D. Rhythmic stabilization
Rhythmic stabilization challenges holding a position using alternating isometric resistance.
What this tests: Match a PNF technique to its purpose.
C. Passive ROM
Check answer
Have another look.
Passive motion does not describe alternating active isometric resistance.
Best answer: D. Rhythmic stabilization
Rhythmic stabilization challenges holding a position using alternating isometric resistance.
What this tests: Match a PNF technique to its purpose.
D. Rhythmic stabilization
Check answer
That’s right.
Rhythmic stabilization challenges holding a position using alternating isometric resistance.
What this tests: Match a PNF technique to its purpose.
QUESTION 2 OF 2
With other conditions held constant, which change generally increases drag during an aquatic exercise?
A. Increasing movement speed
Check answer
That’s right.
Faster movement generally increases drag; larger surface area can also increase resistance.
What this tests: Understand aquatic resistance.
B. Moving more slowly
Check answer
Have another look.
Slower movement generally reduces drag under the stated conditions.
Best answer: A. Increasing movement speed
Faster movement generally increases drag; larger surface area can also increase resistance.
What this tests: Understand aquatic resistance.
C. Reducing the surface area moving through water
Check answer
Have another look.
A smaller surface area generally reduces drag.
Best answer: A. Increasing movement speed
Faster movement generally increases drag; larger surface area can also increase resistance.
What this tests: Understand aquatic resistance.
D. Stopping the movement
Check answer
Have another look.
Stopping removes the movement producing drag; buoyancy can still exert force.
Best answer: A. Increasing movement speed
Faster movement generally increases drag; larger surface area can also increase resistance.
What this tests: Understand aquatic resistance.
