	Underwater swimming pool illumination systems - Patent 4053758
		An underwater swimming pool illumination system includes a lighting assembly having a lamp unit installed within its rear portion in a waterproof enclosure; and the lamp is connected to a low voltage battery.
		In a normal installation of a swimming pool lighting assembly 10 or 22 according to this invention, the assembly is installed at the swimming pool by being fitted to a pad 16 or 16.1 respectively, which is in turn, secured to the swimming pool deck 18.
		The bayonet-like assembly of the base to a pad which is secured to the swimming pool deck assists in overcoming or absorbing the force of a rocking motion which may be imposed upon the lighting assembly due to the wave action of water in the swimming pool.

	Computational fluid dynamics ? A tool for future swimming technique analysis
		The underwater phase of swimming forms a large component of the total event time in modern swimming and can often lead to the difference between a medal and finishing with the rest of the pack.
		To make this model specific to elite swimming performance, it is necessary to apply the movement patterns which are typical of an elite swimmer with a proficient underwater dolphin kicking technique.
		Due to the unavailability of empirical testing to accurately measure drag while swimming throughout an underwater kick cycle, the model was calibrated using steady- state tests (passive drag recorded while in a prone streamlined position).

	Swimming
		Swimming penguins change the angle of the leading edge of their wings, lowering them on the downstroke and raising them on the upstroke, so that both strokes propel the bird forward, resulting in smooth progression through the water.
		Underwater "fliers" are mostly seabirds with short wings, including cormorants, guillemots, auks, shearwaters, and diving petrels.
		Birds that are foot-propelled in water generally hold their wings tightly while diving and swimming, so as to streamline the body.

	Underwater diving - Wikipedia, the free encyclopedia
		The ability to dive and swim underwater can be a useful emergency skill, and is an important part of watersport and navy safety training.
		Assuming that you can swim on the surface, the main obstacle to diving is likely to be the psychological barrier of immersing your head.
		Strokes used in surface swimming must be adapted somewhat, and some arm movements (such as the crawl) cannot be used.

	Swimming pool for rhesus
		Simple immersion in the water and swimming on the surface were generally rare, and did not vary according to social status or conditions.
		The results of this brief study further indicate that provision of a small swimming pool for juvenile rhesus macaques increases play activities and induces recreational diving and underwater swimming, while reducing cage manipulation and the overall incidence of social grooming.
		When a small swimming pool was available, the members of a group of young rhesus monkeys engaged in less social grooming and cage manipulation, and more play activities.

	UNDERWATER SWIMMING BEHAVIOR OF AMERICAN BLACK OYSTERCATCHER CHICKS (Site not responding. Last check: 2007-09-17)
		The method of swimming was very similar to that of Common Murres (Uria aalge), as described by Johnsgard (1987).
		Other than the initial kicks to attain a swimming depth, no further movements of the bird's feet, as either paddles or rudders, were observed.
		This bird proved to be as elusive as the first and larger chick, diving and swimming competently.

	La Vida Crafty - swimming underwater
		the question that actually has to do with swimming underwater: this never happened to me growing up, but now, water comes into and down through my nose every time i go underwater, and i feel like i end up inhaling it, and it's icky.
		The trick to swimming underwater and not getting water up your nose is to constantly keep a little bit of air blowing into your nose from your lungs..it doesn't have to actually escape..but just enough so that the water can't get in, and remember to keep doing it when you come up for air!
		Certain movements, like backflips underwater require additional pressure, but just swimming a bit under water is not a big problem.

	Portable underwater swimming pool light - Patent 5299103
		Underwater pool lighting serves two purposes: it beautifies the pool water at night and also makes it safer for nocturnal swimming since bathers become plainly visible underwater.
		Conventional underwater pool lighting technology generally requires that a sealed lighting unit be submerged and built into the pool wall.
		Since the underwater portion of the apparatus' volume floods with the water, the unit has no positive buoyancy that would require a robust mounting bracket assembly.

		Wolf was doing underwater swimming with his two young brothers and some neighborhood kids, when he fainted.
		Shallow Water Blackout is most commonly associated with skin diving, but the more swimming coaches I speak with, the more I have come to realize that underwater fainting is not at all uncommon in the world of competitive aquatic sports.
		While the underwater swimmer burns up oxygen through exertion, he never gets the signal from the brain — the "bursting lung" sensation — because of the low level of C02 in the lungs and blood.

	Swimming & Diving: butterfly and underwater swimming
		The best way to swim 25 yards is to maintain a streamlined position, relax and use a smooth flutter or dolphin kick to get the distance you are looking for, be careful and never hold your breath in a pool without at least one other person to keep an eye on you.
		The reason that it can be dangerous is that if you push even a little too far you can lose consciousness and drown, that is why it is important to have someone around when you are training.
		Being able to hold your breath doesn't help your swimming to a significant degree, being able to utilize the oxygen is. Every time you hold your breath you build up lactic acid in your muscles which tires them out faster.

		Because drag underwater is lower than drag at the surface, the secret to success in the wave style breaststroke is how much time you spend underwater in a streamlined gliding position, compared to the amount of time spent above the surface.

	Two GUARANTEED Ways To Profoundly Increase Your Intelligence
		This should be well underwater across the bottom of the pool, because we find a distinct difference in response elicited between people who do this and people who simply swim head-down across the surface.
		It is also true that if the underwater swimming were widely adopted at a school, the need for expensive remedial programs would sharply decrease and with it, possibly the school budget accordingly.
		Held-breath underwater swimming, though, is much the stronger procedure for CO2 enrichment and, further, engages that marine diving response to further expand circulation to the brain.

	Visualization For Improved Swimming Efficiency
		In general, when swimming underwater with fins, almost all arm movements are wasted: they add very little to propulsion, but working the arm muscles can consume enormous amounts of energy (as indicated by increased air consumption).
		So, efficiently swimming divers not only have more time to visit underwater splendor, but they often interact with reef inhabitants that would flee from the offending pressure waves generated by divers broadcasting their presence with unnecessary arm and leg movements.
		This is also a time when I point out that swimming on the surface without fins is primarily an upper body skill, whereas swimming underwater with fins is primarily a lower body activity.
