# AQUATIC ACTIVITIES ## PE and Health 4 ## AQUATICS - Water has special characteristics that provide a unique environment for activities and good workout. - These characteristics include buoyancy, hydrostatic pressure and enhance cooling. ## BUOYANCY - It is the upward force of the water on an object. - This is the reason why boats and people float on water. - It also gives a weightless feeling, which makes it easier to move, lift knees or even jog in water. ## HYDROSTATIC PRESSURE - The pressure exerted by the water at equilibrium due to the force of gravity. - It is the weight of the water pressed down on the object. - Hydrostatic pressure exerted on the body from all sides and this pressure, combined with buoyancy, helps keep standing balance in water. ## ENHANCE COOLING - Transfers heat away from the body much quickly than air given in the same temperature. - This is the reason we can stay longer in water and can tolerate longer workouts without feeling being overheated. ## AQUATICS ACTIVITIES ### SNORKELING - Snorkeling is peeking through life underneath water by swimming with the aid of a snorkel and mask. Through snorkeling, one can observe the underwater attractions for a longer period of time, without the need to constantly resurface to gasp for air, and with relatively lesser effort. - Snorkeling helps the overall fitness of a person. It works out the quadriceps, hamstrings, calves, ankles, hip, flexors, core muscles, and shoulders while swimming. ### CANOEING - The word 'canoe' originated from the Carib word 'kenu' which means dugout. - Canoes were originally made from large tree trunks. - The more well-known version of the canoe was introduced by the North American Indians where the frame was built from wooden ribs. - The oldest known canoe, Pesse Canoe, believed to be constructed between 8200 and 7600 B.C. was found in the Netherlands ### KAYAK - Also called qajak, means “man's boat" or "hunter's boat" originated from the Inuit and Aleut tribes of Arctic North America. - The early kayaks were very individualized as each kayak was crafted by the user, basing the measurement to the frame of his body and not on any standard. - The oldest existing kayaks are exhibited in North America Department of the State Museum of Ethnology Munich. ### SCUBA Diving - Scuba is an acronym for Self-Contained Underwater Breathing Apparatus. - Scuba diving is a diving method where a diver uses a regulator as the breathing apparatus and a tank with compressed air which enables the diver to breathe normally underwater. With this equipment, a diver can explore the waters for a longer period of time and at greater depths.
