◉Muscles are generally found in pairs in the body on either side of a
joint, allowing them to move bones in both directions. Paired muscles
have a relationship that allows one muscle to relax (antagonist) or stretch
while the other muscle is shortening or contracting (agonist). These
actions create concentric and eccentric muscle actions. Answer: What
muscles are responsible for primary movements in exercise?
◉Movement on land is affected by the pull of gravity. Any movement
performed away from the ground is gravity resisted. This movement
creates a concentric muscle action. Any movement performed toward the
ground is gravity assisted. Because gravity assists downward movement,
there is an eccentric muscle action to lower a limb or weight toward the
earth with control. Answer: How does gravity affect the muscle being
used and the type of the muscle action?
◉Introducing drag equipment simply increases the drag forces of the
water. The muscle equation becomes the same as the equation for
moving in the water without equipment; however the resistance force
,has been magnified. Answer: How do the water's viscosity and drag
affect the muscle use equation when submerged?
◉Buoyed muscle action is opposite of weighted muscle action. The
buoyancy vector is vertical, points upward, and buoyancy affects
movement toward the surface and bottom of the pool. Any movement
toward the bottom of the pool with a buoyant object is buoyancy resisted
and usually creates a concentric muscle action. Any movement toward
the surface of the water is buoyancy assisted and usually creates
eccentric muscle action. Answer: When using buoyant equipment, in
which direction is the movement resisted and in which direction is the
movement assisted?
◉Muscle action for weighted resistance in the water is very similar to
land. Weighted equipment sinks in the water and is influenced by the
forces of gravity. As long as the weighted resistance is denser than water
and sinks, it will be affected by gravity. Any movement performed
upward against the forces of gravity is gravity resisted and usually
creates a concentric muscle action. Any movement performed downward
is assisted by the forces of gravity and usually creates eccentric muscle
action. Answer: How does using weighted equipment in the water differ
from using weighted equipment on land?
◉Drag coefficient is an experimentally determined value that represents
the relative effect of an object's frontal profile on its fluid drag. This
value varies with it's shape. These numerical drag coefficient values
indicate the relative difficulty of the respective shape to be moved
through the water. These values presume that all objects have the same
, projected area. Answer: What is "drag coefficient"? What affects the
intensity of drag equipment?
◉No. The muscle action created by rubberized equipment, is virtually
the same regardless of the environment. Any muscle action away from
the anchored point is resisted and concentric. Any muscle action toward
the anchored point is assisted and eccentric. Answer: Is using
rubberized equipment in the pool any different from using it on land?
◉Flotation equipment is generally not used to increase resistance, rather
it is primarily used to create normal buoyancy. The type and size of
flotation equipment can affect neutral positioning in the water. Body
composition, in particular fat deposits and muscle density, affect the
placement and use of flotation equipment. Answer: How does the type
and size of flotation equipment affect positioning in the water?
