What are water sports activities?
Water sports or aquatic sports are sports activities conducted on waterbodies and can be categorized according to the degree of immersion by the participants. A variety of water sports; from top left: diving, surfing, water polo, synchronized swimming, swimming, rowing, yacht racing, dragon boat racing, kayaking. The term “Aquatic Activities” covers all these plus swimming, and can be defined as motor activities performed in water for purposes that may be utilitarian, competitive, educational, therapeutic, or recreational.Aquatic Activities means all water-related activities including swimming, boating, fishing, hot tubs, water parks and those activities that take place near to water.The term air sports covers a range of aerial activities, including air racing, aerobatics, aeromodelling, hang gliding, human-powered aircraft, parachuting, paragliding, soaring, and skydiving. Air Sports.The types of activities include scuba diving, snorkeling, surfing, bodyboarding, wakeboarding, kiteboarding, kite surfing, stand-up paddleboarding (SUP), canoeing, kayaking, sail boating, water skiing, personal watercraft (PWC), fishing and more. New marine sports are also being created one after another.
Why is water activity 1?
Water activity is based on a scale of 0 to 1. It is defined as the vapor pressure of water over a sample divided by the vapor pressure of pure water at the same temperature. In other words, the more unbound water we have, the more likelihood we have of microbial spoilage. In food science, water activity (aw) of a food is the ratio of its vapor pressure to the vapor pressure of water at the same temperature, both taken at equilibrium. Pure water has a water activity of one. Put another way, aw is the equilibrium relative humidity (ERH) expressed as a fraction instead of as a percentage.The formula for calculating water activity is: aw = p/ps. These results are presented on scale of 0-1, where 0 shows that there is no available free water, while 1 indicates that all of the water in the product is available.In food science, water activity (aw) of a food is the ratio of its vapor pressure to the vapor pressure of water at the same temperature, both taken at equilibrium. Pure water has a water activity of one. Put another way, aw is the equilibrium relative humidity (ERH) expressed as a fraction instead of as a percentage.Water activity (aw) is the measure of the energy status of water in a system. It is a principle of thermodynamics and follows the same rules. A higher water activity means more energy and the water can do more work, such as microbial growth, moisture migration, or chemical and physical reactions.
What is a good water activity?
The moisture condition of a product can be measured as the equilibrium relative humidity (ERH) expressed in percentage or as the water activity expressed as a decimal. Most foods have a water activity above 0. In food science, water activity (aw) of a food is the ratio of its vapor pressure to the vapor pressure of water at the same temperature, both taken at equilibrium. Pure water has a water activity of one. Put another way, aw is the equilibrium relative humidity (ERH) expressed as a fraction instead of as a percentage.Water activity is equal to equilibrium relative humidity divided by 100: (a w = ERH/100) where ERH is the equilibrium relative humidity (%).
What are the benefits of aquatic activities?
Water also offers natural resistance, which can help strengthen the muscles. Aquatic exercise can have many health benefits, such as improved heart health, reduced stress, and improved muscular endurance and strength. Exercising in the water can be a great way to add physical activity into your life. In conclusion, practicing watersports is a fun and exciting way to improve your physical and mental health. Whether you are looking to improve your cardiovascular health, build strength and endurance, or simply relieve stress, there is a watersport activity that is right for you.
