Water Sports - Surfing
The water within the human body has a little less density compared to that of the water outside, which forces the body to the surface. To move forward, the water around should be pushed backward and to float, the water should be pushed downward. The pushing is done by using hands as paddles and kicking with the legs. It takes less effort to swim and float in the ocean than in a swimming pool because salty water has more density than fresh water because of the salts. The basic principle involved in all swimming styles is that the body should be kept parallel to the surface of the water and the hands should be positioned in outward direction, inline with the head, so as to cut though the water and reduce the friction. The more the body is slanted, the more the drag. Also, by extending the hands, the average length at the water line is increased which is directly proportional to the increase in the speed. The sign of a good surfer is that he is able to catch the wave before other surfers can. Beginners find it difficult to catch the wave at all. Once the wave is caught, the surfer can stand on the surfboard and stay in front of the curl of the wave, also known as the white water. The wave carries the surfer and takes him in a forward direction. A skilled surfer is able to take total charge of a challenging situation and at the same time maneuver like curving or turning. Some tricks practiced by experienced surfers are floater, cutback, air and off the lip. The most difficult trick is the surf inside the tube formed by the closed curl of the wave. Surfing has dangers like any other water sport, the major being drowning. The surfer must at all times keep his feet strapped to the surfboard to avoid any mishap during a wipeout. In some cases, the surfers can loose their consciousness and the surfboard can be entangles in a rip current, so it is advisable to not to surf alone. The nose or fins of the surfboard cause nearly sixty six percent of injuries to surfers. The water can infect the cuts caused by them. There can be possibility of colliding with objects under water like corals and rocks, which can sometimes even lead to death. Sea animals, like shark, jellyfish and stingrays, should be watched out for. Surf forecasting is done to aid surfers and help them enjoy their experience. It involves information technology involving mathematical modeling to represent the wave in a graphical manner. This gives an idea about the direction and size of the swells in the oceans around the world. There are many surf forecasting websites where a surfer can get all the necessary information before going out to surf where artificial reefs are constructed with all the factors under control. Wave pools also have been built to attract tourist, but the count is less because of the huge cost involved. The problems and hazards related to swimming are drowning and water inhalation in a contaminated environment. Extreme exhaustion can lead to unconsciousness. Weaker people should avoid it because it can be a cause to heart attacks, stroke, shallow water blackout and carotid sinus syncope. Excess water intake in salty water can form foam in the lungs, which effects breathing badly. Regular swimmers get exostosis or swimmers' ear, which is abnormal growth in the ear canal and athlete's foot, which is bacterial infection in between the toes. Chemicals in the swimming pools can cause skin and eye irritation and can even discolor the hair. Asthmatics should avoid excess swimming in a swimming pool, as the chlorine inhalation will affect their lungs badly. While swimming in the ocean, precautions should be taken, as there is an increased risk of getting jellyfish sting or harm from any other aquatic animal.
