The Roblox Studio interface as of August 2024. Roblox Studio is the platforms game engine [26] and game development software. [27] [28] The engine and all games made on Roblox predominantly uses Luau, [29] a dialect of the Lua 5.1 programming language. [30] Since November 2021, the programming language has been open sourced under the MIT License.
In the Drownproofing survival technique, the subject floats in a relaxed, near-vertical posture, with the top of the head just above the surface. Using the arms or legs to exert a downward pressure, the subject raises himself sufficiently so that the mouth is above the surface and a breath is taken, before dropping back into the relaxed float.
In ordinary swimming on the right side, the left arm moves gently in the water, almost at rest. [3] Then, when the used arm becomes tired, the swimmer turns on the other side, and the left arm works while the right arm rests. [3] The legs move in opposite directions with legs bent, and straighten as they come together.
Swimming underwater is faster than swimming on the surface. Underwater swimming is not its own category in the Olympics, but in the 1988 Olympics several competitors swam much of the backstroke race underwater. After that, the Olympics created a rule that swimmers are only allowed to stay underwater for the first 10 meters (later changed to 15 ...
The eggbeater kick is an efficient method of treading water. It involves the swimmer in a "sitting position" in the water. The swimmer's back must be straight, knees bent so that the thighs are parallel to the surface of the water, and lower legs perpendicular to the surface.
To an untrained observer, it may not be obvious that a drowning person is in distress. The victim may appear to be swimming safely, but the victim is actually within 20–60 seconds of sinking under the surface and thus dying. [3] They extend their arms laterally and press down on the water's surface in order to lift their mouth out of the water.
Swimming classification generally has three components. The first is a bench press. The second is water test. The third is in competition observation. [48] As part of the water test, swimmers are often required to demonstrate their swimming technique for all four strokes. They usually swim a distance of 25 meters for each stroke.
The swimmer travels up with arms along their sides, rotating to breathe bi-laterally. A variation on this is swimming with one arm along their side and one arm performing the arm action. At the end of the length, the swimmer swaps sides. This drill supports rotation and breathing, single arm training, and streamlining in front crawl. [14]
