Final Exam Aquatics

Question 1

How does percentage of BW change with immersion level?

Answer 1

hip- 50% BW
chest- 33% BW
neck- 10% BW

Question 2

What are the magic numbers for water temp?

Answer 2

25 - 37 degrees Celcius

25 = hard to maintain core warmth during immersed exercise
37 = hard to cool yourself off because you can't sweat

Question 3

How do you gauge exercise intensity during aquatic exercise?

Answer 3

• HR intensity is 7-20 bpm lower for full body immersion
• RPE is special for beginners because they will think it is harder that it is aerobically
• talk test

Question 4

How do you progress intensity for resistance exercise in aquatic environment?

Answer 4

increase surface area of speed to increase resistance

Question 5

Properties of Water and Why are They Important

Answer 5

1. buoyancy- decreases BW, buoyancy assisted, resisted, super resisted
2. viscosity- make movement harder by increasing surface area or speed or both
3. surface tension- hard to break so activity at surface is harder rather than under water
4. hydrostatic pressure- don’t want to put someone with compromised heart or lungs in water because system isn’t good enough to overcome pressure, good for swelling/edema, comforting and soothing
