Alright, im new to this site, Im not a usual swimmer but i recently got in the pool and feel in love. I quickly made friends at the local pool on-base. Im a United States Marine with hopes and dreams in Becoming a Reconnaissaince Marine. In other words Marines with Gills. They are like the SEAL's from the Navy and Pararescue from the Air Force. The guys at the pool quickly tought me how to swim "the right way" cross-over and *** stroke as well as the Side-stroke and other technics. i go to the pool everyday. My biggest problem is dealing with the underwater 25 meter swim. To become a Recon Marine i have to accomplish the following....
1) 500 meter swim with out touching the floor in under 17min.
2) 30 min. tread
3) Deep end Rifle retreaval and then treading water for 5 sec.
4) 5 min. water float by using trousers as floating devise
5) 25 Meter underwater swim (my problem)
I have no problem with any of the others but the 25 meter kills me only because i feel like my lungs are going to explode. is there any tips of any kind out there that can prepare me for my "indoc" or evaluation to see if im sea worthy and serve as a Recon Marine. Thanks for hearing me out. :banana:

Syd: there is no solution. You can train your mind to function with an elevated pC02, but as long as you are swimming above a certain effort, you will produce in excess of what you can get rid off. The lack of strengh or the swimming getting slower in a fast 100 or even a 50 is a factor of muscle fatigue, which involves many systems, including the oxygen or lack off. But the pure feeling of being out of breath is always related to your C02 and will only be alleviated by producing less or breathing more. When not in exercise, just pure diving or breath holding when you breathe you immediately feel better...when finishing a fast swim (which purists might say was anaerobic, because you run out of oxygen in the cellular level) you take more than one breath to get into normal breathing because you are eliminating an accumulation of C02 from exercise plus lack of breathing. When you run fast you also take sometime to get back into normal breathing, due to same factors (although the other factors such as oxygen depletion and so forth are also participating in this event).
Jim, excessive hiperventilating can produce light headness or dots. A common finding in panic attacks. This is due to low C02 content in blood (don't know why ). But lack of oxygen is also found in light headness. Also a small disturbance in your balance system (inner ear and so forth) might cause nausea/or light headness, irrespective of ventilation.
This is an extensive and interesting subject matter. Most people think being out of breath is being out of oxygen. But then, most people think the tanks used in Scuba Diving have pure oxygen. Costeau discovered the hard way (passing out) that pure oxygen is detrimental in diving and acts funny when person is under pressure. Last bit of useless information: american space capsules have a mixture of oxygen and nitrogen to make the 20-80 balance; the russians have 100% oxygen with one third atmospheric pressure to make the capsule safe. billy fanstone
