NETURAL
BUOYANCY
Neutral
Buoyancy Swim
After
you've established neutral buoyancy,
your instructor will have you swim 10
meters/yards or farther, remaining neutrally
buoyant. During this swim, pretend you're
swimming over a reef with sensitive
aquatic organisms and avoid any contact
with the bottom. This simulates how
you swim avoiding damage to the environment
when making open water dives.
Cramp
Removal
A
cramp is a painful, involuntary muscle
contraction, which, as a diver, you
may experience in your leg or foot muscles.
Several things can contribute to cramps:
dehydration, working the muscle beyond
its fitness level, restricted circulation,
cold water, and all of these working
together. Your fins can contribute to
cramping if the blade is too large for
your leg strength, or if the foot pockets
are too small and your feet don't go
in them properly. Fitness, proper fin
selection, practice, proper insulation
and pacing your activity, will help
you avoid cramps.
But
they can happen anyway. Like most problems,
it's more of an irritation than an emergency
if you stop and think about what to
do. For a cramp, stop and rest the cramped
muscle. Stretch and gently massage it
to increase circulation and pull out
the cramp. If you have a leg cramp in
your calf muscle, you can stretch it
by grasping the fin tip and pulling
it toward you while you push with your
leg. Your buddy can also brace the fin
tip for you
