Training Tips: HydrationOctober 9, 2003Sport Nutrition Advisory Committee of the Coaching Association of Canada Fluids for Athletes - how much should an active person drink? Recent articles have reported that "too much water can make you sick". While it is possible to consume too much water, dehydration continues to be a much greater threat to performance and health. How do you know how much to consume? The Position of Dieticians of Canada, the American Dietetic Association and the American College of Sport Medicine "Nutrition and Athletic Performance" was published in 2000. The Sport Nutrition Advisory Committee (SNAC) of the Coaching Association of Canada has produced a nutrition tip sheet "Fluids for Athletes". It summarizes the recommendations from the three professional organizations, providing a quick reference for coaches, athletes and active Canadians. This nutrition tip sheet is available on www.coach.ca/e/nutrition/resources.htm.The amount of fluid you need depends on a number of factors - the weather conditions (temperature and humidity), the activity (type and duration) and your body (age, size, gender and sweat rate). A person needs fluid before, during and after exercise. Consuming 150 to 350 mL every 15 to 20 minutes during physical activity is recommended. In general, individuals should strive to keep their body weight loss during physical activity in the heat to less than 2% of total body mass - i.e. for a 70 kg person this is less than 1.4 kg body weight loss (or 1.4 L water) due to sweating. In some situations, carbohydrate added to the fluid will benefit performance. Electrolytes can also play a role. Talk to an expert to understand your needs.

Training Tips: Freestyle TurnsBy Gary Vandermeulen Hydro Dynamics Consulting gmeulen@seaside.net Freestyle
turns can become your greatest strength.
However you must decide to dedicate yourself to making them better. With
everything that you have done thousands of times it becomes harder and harder to
change because the number of poor turns compared to good turns is against you.
So the first thing you have to do is be prepared to dedicate yourself to
making every single turn as good as you can.
Once you have made the decision to do that, this is what you do: Divide
your turn into phases, 1.Swim
up. Your
turn is all of these things. It is not just a flip over.
In the
Swim up (1) you have to look for the wall and your brain will
automatically give you a feel for how many strokes it is until the wall.
This needs to be done just outside the flags.
It is very important not to lift your head to do this, so you must use
your peripheral vision and the 'T' on the bottom of the pool.
For some turns, where the wall meets the bottom is an even better
indictor.
In this swim up phase you need to take your last breathe two or three
strokes before the wall.
You need to do this so you can keep your concentration on how far you are
away.
If you breathe just before the wall or at the wall you have given your
turn no chance of being fast.
You might as well do a hand touch turn if you breathe on your last
stroke. In the
Arm action
(2) part of your turn you will need to be able to turn on either arm.
That means you will have an extra option compared to a one armed turner.
Most swimmers are.
In the arm action into the wall your second last stroke stays at your
side with the hand remaining palm up.
Your last stroke will follow a normal stroke pattern but your head
follows your arm down into a tuck.
Your last stroke will then meet up with your second last stroke which is
still at your side.
Your two arms now STAY in the same position at your sides, while your
body flips over them.
Your two arms help your flip over while remaining in basically the same
position.
Once your legs get onto the wall your hands will still be together but
waiting for your push off, over your head.
In the
Leg action (3) phase, your legs will be doing their flip part of the
turn.
The quicker this is, the faster your turn.
Immediately once your two arms are at your sides, you do a very quick
dolphin kick to initiate your flip.
Tuck your forehead towards your knees after the dolphin kick.
Your arms will push against the water in an upward scull and you will
drive your feet towards the wall.
You should continue to be looking at your knees until your feet are on
the wall.
If you were to swim in freestyle and out backstroke your feet would be
best planted upside-down.
For freestyle, your feet should be about 45 degrees but not sideways.
Keep your tuck position moving until your feet are directly opposite the
best streamlining tangent.
The Plant
on the wall (4) portion is now the beginning of the changed direction of
your turn.
The first half with practice will be done without The Push
off (5) is set by lining up the hands-shoulders-hips-feet.
This line has to be parallel to the surface.
You must squeeze your ears before you push off.
Most people streamline ‘after’ they push off.
This is obvious when you see turns in slow motion underwater.
However, once your feet have left the wall you immediately begin to slow
down.
If your head is squeezed then you will slow down less.
Just after you push off one foot needs to cross the other slightly.
This will make a slight spin onto your front from your upside-down
position.
Do not try to set your self on your front during the plant.
This is a common mistake.
During the push off you need to be aware of your position in the water.
Begin to spin towards the side you are leaning by angling your feet over
each other. You will want to be going in a straight line.
You may have to adjust using your arms and legs to get that straight line
but eventually you can use this part of your turn as a very fast moving rest!
WHAT!?
A rest, yes indeed, squeeze your head take a half second to two second
rest and when you feel your speed decrease begin to add your kick.
In the sprint events you will want to kick sooner.
Since you should be traveling faster than 2 meters per second you will be
going faster that you can swim.
So enjoy the product of an excellent turn by not slowing yourself down
with an immediate leg kick.
You
are not finished your turn until you have done your Swim out (6). Good
luck, Gary

Running guidelines for Modern Pentathlon Edition I (Jan94)Written by Phil McOrmand, Coach NCCP 2 Novices: Juniors: Seniors: General Guidelines: Don’t run alone unless you
are in familiar areas or not far from home. Always let your parents know where
you are and when you will be done. Don’t run in the dark unless you are
wearing a reflexive vest. Try to run with a friend, it’s more fun that way. Air Pistol Shooting for Modern PentathlonBy Art Tomsett, Shooting Coach, NCCP Level 2 Coming soon... |
