What are the four physical properties of water
buoyancy
hydrostatic pressure
viscosity
surface tension
What are the three types of buoyancy
positive, negative, and neutral
which type of buoyancy will an object have if it floats
positive
which type of buoyancy will an object have if it sinks
negative
which type of buoyancy will an object have if it will remain suspended in water
neutral
Objects with positive buoyancy will:
Assist movement toward the pool _____
Resist movement toward the pool ____
Support movement on the ____ of the water
surface
bottom
surface
Which muscle group is working during bicep curls with foam dumbbells that have a positive buoyancy
Concentric triceps and eccentric triceps
Objects with negative buoyancy will:
Assist movement toward the pool ____
Resist movement toward the pool _____
bottom
surface
Which muscle group is working during bicep curls with water weights that have a negative buoyancy
concentric biceps and eccentric biceps
Objects with neutral buoyancy will:
Move with the ____ amount of resistance in all directions independent of the direction of the water surface
same
Which muscle group is working during bicep curls with water paddles that have a neutral buoyancy
concentric biceps and concentric triceps
Which term is defined as the center of volume of the body displacing the water
center of buoyancy
Where is the center of buoyancy located
in the chest area (lungs, air pockets)
buoyancy bodies have more (muscle/fat)
fat
During aquatic therapy joint capsules are (open/closed) which allows the patient to have greater flexibility
open
____ ____ represents the ratio of density of the substance to the density of water
specific gravity
What is the specific gravity of water
1.0
(higher/lower) lean body mass athletes have a SG greater than 1 which makes them not as buoyant
higher`
what is the average SG for the human body
,97-,95
Does hydrostatic pressure increase or decrease with depth
increases
What are the affects of hydrostatic pressure on the body
increased blood flow
improvement with dependent edema
renal blood flow increased by 10%
Friction between molecules of a liquid cause them to adhere to each other which is called _____ or to a submerged body which is called _____
cohesion and adhesion
____ of the water can be used to either assist or impede movement
viscosity
what is the term that is defined as the force exerted between the surface molecules of a liquid
surface tension
avoid ____ out of the water
snapping
Does it take more or less force to move an object from out of the water to underneath the water’s surface in comparison to the other way around
more
______ are the properties of fluid in motion
hydromechanics
What are the three types of hydromechanics in the PP
laminar flow
turbulent flow
drag
What type of hydromechanics occur when all molecules move parallel to each other
laminar flow
what type of hydromechanics occur when all molecules are not moving parallel to each other
turbulent flow
____ is the cumulative effects of turbulence and viscosity acting on an object in motion
drag
____ is the force you feel that opposes your movements in the water
drag
What is drag affected by?
frontal surface area, velocity, and shape of objects
Water retains heat _____ more times than air
1000
Water conducts head ____ times faster than ait
25
what is the clinical significance of thermodynamics of water
patients body temp rapidly affected by water temp while the water itself remains minimally effected
What type of equipment can be used to aquatic therapy
weights finds hydrotones paddles noodles foam dumbbells kick board thera tube belts cervical float
What is the goal of the protection phase in aquatic therapy
to get pain to decrease
