CONCEPTS
◉How is motion in the aquatic environment affected by the water's
viscosity? Answer: Water is more viscous than air. The friction between
molecules in water is what causes resistance to motion when exercising.
A combination of the surface area of an object and its speed determines
the resistance to the motion caused by the fluid viscosity (drag). During
exercise, additional resistance increases the intensity of the movement
and thus requires greater muscular effort.
◉How do body, water, and limb inertia affect intensity in aquatic
exercise? Answer: Because the water offers resistance, it takes more
force or energy to initiate and change movement than continuing to use
the same movement. The primary resistance to the limbs in the water is
from drag, which relates to a combination of viscosity of the water and
the relative speed of the motion between the limb and the water.
◉How does changing the body's position when traveling affect intensity
Answer: (1) Changing frontal resistance when traveling, (2) changing
,the length of the lever or limb, or (3) adjusting hand positions can alter
intensity.
◉Which hand position is most effective for pulling water and adding to
the upper torso training effect? Answer: An open, slightly cupped hand
with fingers relaxed and slightly spread
◉Why is simply increasing the speed of movement not the best
alternative for increasing intensity in the aquatic environment? Answer:
ROM and body position (form) can be compromised
◉How can you apply the concept of acceleration in aquatic movement?
Answer: You can increase intensity using the law of acceleration by
applying more force to the pool bottom to jump higher at the same
tempo.
◉What influence does the combination of arm and leg movements have
on the intensity of aquatic exercise? Answer: When the arms and legs
are used to create opposing reactions, the arms are considered to be
impeding the leg movements and thus raising the intensity level.
Assisting arm or leg movements create less turbulence and resistance
and, therefore, less intense. Impeding arms/legs create more turbulence
and resistance and are, therefore, more intense.
◉Why is a knee lift a less-intense movement than a front kick? Answer:
The system of levers in the body are what allows movement. The ratio
, between the length of the force arm and the resistance arm is what
determines mechanical advantage. In exercise, the length of the
resistance arm of the lever affects intensity of the amount of energy
required by the muscle to move the limb or body part. A knee lift
(shorter resistance arm) requires less effort from the iliopsoas muscle
than a straight leg kick (longer resistance arm)
◉TRUE OR FALSE: Motion occurs when there is a change in location
in space and is a relative, rather than absolute, term. Answer: True
◉Research studies on joint motion when walking in a pool have shown
that individuals have more than ______ percent higher joint motions
(range of motion) than when walking on land. Answer: 30
◉Name Sir Isaac Newton's three Laws of Motion. Answer: Law of
Inertia
Law of Acceleration
Law of Action and Reaction
◉Explain the Law of Inertia. Answer: An object remains stationary
unless a force causes it to move; i.e., object remains at rest or in motion
with constant velocity unless acted on by a net external force.
