what will happen when u don't dive properly?

the harder you hit the water at an odd angle the more youll hurt yourself such as broken ribs and internal bleeding, try to stay completely vertical when your diving to maintain a good position

NO!!!  Many people tell me "Everyone can float on their back."    I tell them I don't float.  So they proceed to tell me how I do it wrong.  \n\nSo they (even swim instructors) get me to float on my back and let go, my legs start sinking and slowly the rest of me sinks. Until my nose is underwater and where I finally stop sinking, but then I can't breathe.

your body is accelerating at the same rate of the car so no matter what you do, you will impact the water at 9.8 meters per second squared. that should kill you. the same happens in falling elevators. if you jump before it hits the bottom, you will break your legs or die.

If you feel like you are going to fall, then your equilibrium might be off.  You should have a physical done soon to get checked out.

You have tired out and possibly sprained your diaphragm, the muscle below your rib cage which expands and contracts your lungs.  This is similar to the shortness of breath people have when the "wind is knocked out of them."\n\nI don't think you can get rid of the groggy feeling you get when you dive a lot.

Not very much.  The water pressure on your body would prevent you from being able to bring in air that is at normal atmospheric pressure.  You need a compressor on the surface and a hose to breath from.

Your lungs will do the same job as the beach ball.  If you can relax and keep air in your lungs, you will float.  Try in shallow water, take a good breath, relax and lay back.  You will be fine.

It's a question of the relative amounts of muscle and fat, together with the density of your bones. Basically, if your overall body density (mass/volume) is >1 you will sink, if it's <1 you will float.\n\nThe air in your lungs *does* make a difference, since taking a deep breath both expands your volume, and increases the amount of low-density stuff in that volume. If I have a lungful of air, I can just about float; breathe out, and I sink.

That happens to me too, after I make any sudden movements. I don't think you're going to drop dead from a heart attack any second now, but I do think if you don't do something about it it could lead to heart/chest problems later in life. I'm assuming it's your heart, unless you have a broken upper rib right in the middle of your chest. It's good that you've gone to a doctor to check things out, because you're better safe than sorry. If looking to be on the safe side, you should probably just drink lots of water and eat bananas or something because water flushes all of the bad toxins out of your body.

you are naturally bouyant, fill your lungs with air as much as you can, and you will float... just dont panic when a wave hits your face

...and what happens if you don't do the exercises??\n\nGo For It!!

No.  There's nowhere near enough pressure.  You need to go down about 50 meters before the bends can hit you upon surfacing.  Depending on your physicall fitness, you may even be able to go deeper.

Yes...more dryland, stretching exercises, and hollow out slightly before entry. Do line ups and get body control. Diving can torque backs either by entries not lined up, or the board's rebound itself.

chlorine would be the number one suspect\n\nnumber 2, you might want to close your eyes when you dive in, change of pressures\n\nnumber 3 dont dive face first

I float in a fresh water pool, don't you?  My head is not above water, but if my lungs are full of air I do not sink.  If I empty my lungs then I will sink.  What is your question?

depends on the kind of fall and the trajectory

The diving speed would be constantly changing. You will need to set up an integral and calculate the volume of crap coming out of the men at each moment... Also were they eating a high fiber diet or more of a liquid type diet. We need more info for a truly correct answer.\n\n\nI have always wanted to know if you are skydiving naked and you crap your pants will the crap float next to you or will it tend to float upward and possibly land on your head once you pull you rip cord?\n\n\n\n\nfunny how toilet humor never gets old!!! keep it up!
