Swimming Technology Research
Typically, poor technique and over excessive use of the muscle group can be the primary causes of injury. Through communication between swimmers, coaches, parents, and medical professionals, any issue can be diagnosed prior to a serious injury. Additionally, proper warm-up, stretches, and strength training exercises should be completed before any rigorous movements. In treating a rotator cuff injury, the most important factor is time. Due to the nature of the joint being primarily stabilized by muscle and tendon, the injury must be fully healed to prevent recurrence. Returning to swimming or other demanding exercises too soon can result in degeneration of a tendon which might result in a rupture.
During the rehabilitation period, focus should be placed on rotator cuff and scapular strengthening. Another common injury is breaststroke knee, also known as swimmer's knee. This injury is caused by the kicking movement used while swimming breaststroke. The kicking movement will cause wear and tear on the knee and it will eventually lead to constant pain. In recent studies it has been found that initially, the pain is only experienced when the kick was executed, but eventually the pain spread to other regular day-to-day activities, athletic and non-athletic.

Disinfection is critical to protect against pathogens, and is best managed through routine monitoring and maintenance of chemical feed equipment to ensure optimum chemical levels in accordance with state and local regulations.
Chemical parameters include disinfectant levels according to regulated pesticide label directions. Human tears have a pH of 7. Total alkalinity should be 80— ppm and calcium hardness between and ppm. Good hygienic behavior at swimming pools is also important for reducing health risk factors at swimming pools and spas. Showering before swimming can reduce introduction of contaminants to the pool, and showering again after swimming will help to remove any that may have been picked up by the swimmer. Those with diarrhea or other gastroenteritis illnesses should not swim within 2 weeks of an outbreak, especially children.
Cryptosporidium is chlorine resistant. To minimize exposure to pathogens, swimmers should avoid getting water into their mouths and never swallow pool or spa water. Maintaining an effective concentration of disinfectant is critically important in assuring the safety and health of swimming pool and spa users. When any of these pool chemicals are used, it is very important to keep the pH of the pool in the range 7. However, according to the Hamilton Index, a higher pH can reduce unnecessary chlorine consumption while still remaining effective at preventing algae and bacteria growth. To help ensure the health of bathers and protect pool equipment, it is essential to perform routine monitoring of water quality factors or "parameters" on a regular basis.
This process becomes the essence of an optimum water quality management program. Conventional halogen-based oxidizers such as chlorine and bromine are convenient and economical primary sanitizers for swimming pools and provide a residual level of sanitizer that remains in the water. Chlorine-releasing compounds are the most popular and frequently used in swimming pools whereas bromine-releasing compounds have found heightened popularity in spas and hot tubs.
Both are members of the halogen group with demonstrated ability to destroy and deactivate a wide range of potentially dangerous bacteria and viruses in swimming pools and spas. Both exhibit three essential elements as ideal first-line-of-defense sanitizers for swimming pools and spas: they are fast-acting and enduring, they are effective algaecides, and they oxidize undesired contaminants. Swimming pools can be disinfected with a variety of chlorine-releasing compounds. The most basic of these compounds is molecular chlorine Cl 2 ; however, its application is primarily in large commercial public swimming pools.
Inorganic forms of chlorine-releasing compounds frequently used in residential and public swimming pools include sodium hypochlorite commonly known as liquid bleach or simply bleach , calcium hypochlorite and lithium hypochlorite. Chlorine residuals from Cl 2 and inorganic chlorine-releasing compounds break down rapidly in sunlight. Chlorinated isocyanurates, a family of organic chlorine-releasing compounds, are stabilized to prevent UV degradation due to the presence of cyanurate as part of their chemical backbone.
These are commonly sold for general use in small summer pools, where the water is expected to be used for only a few months and is expected to be regularly topped up with fresh, due to evaporation and splash loss. It is important to change the water frequently, otherwise, levels of cyanuric acid will build up to beyond the point at which the mechanism functions. Excess cyanurates will actually work in reverse and will inhibit the chlorine. A steadily lowering pH value of the water may at first be noticed. Algal growth may become visible, even though chlorine tests show sufficient levels.
Chlorine reacting with urea in urine and other nitrogen-containing wastes from bathers can produce chloramines. Chloramines typically occur when an insufficient amount of chlorine is used to disinfect a contaminated pool. Chloramines are generally responsible for the noxious, irritating smell prominently occurring in indoor pool settings. A common way to remove chloramines is to "superchlorinate" commonly called "shocking" the pool with a high dose of inorganic chlorine sufficient to deliver 10 ppm chlorine.
Regular superchlorination every two weeks in summer helps to eliminate these unpleasant odors in the pool. Levels of chloramines and other volatile compounds in water can be minimized by reducing contaminants that lead to their formation e. Medium pressure UV technology is used to control the level of chloramines in indoor pools. It is also used as a secondary form of disinfection to address chlorine-tolerant pathogens.
A properly sized and maintained UV system should remove the need to shock for chloramines, although shocking would still be used to address a fecal accident in the pool. UV will not replace chlorine but is used to control the level of chloramines, which are responsible for the odor, irritation, and enhanced corrosion at an indoor pool. Copper ion systems use a v current across. Alternative systems also use titanium plates to produce oxygen in the water to help degrade organic compounds. An electrically operated water pump is the prime motivator in recirculating the water from the pool.
Water is forced through a filter and then returned to the pool. Using a water pump by itself is often not sufficient to completely sanitize a pool. Commercial and public pool pumps usually run 24 hours a day for the entire operating season of the pool. Residential pool pumps are typically run for 4 hours per day in winter when the pool is not in use and up to 24 hours in summer. To save electricity costs, most pools run water pumps for between 6 hours and 12 hours in summer with the pump being controlled by an electronic timer. Most pool pumps available today incorporate a small filter basket as the last effort to avoid leaf or hair contamination reaching the close-tolerance impeller section of the pump.
A pressure-fed sand filter is typically placed in line immediately after the water pump. A pressure fed sand filter is termed a 'High Rate' sand filter, and will generally filter turbid water of particulates no less than 10 micrometers in size. Indicated by a pressure gauge on the pressure side of the filter reaching into the 'red line' area, the pool owner is alerted to the need to 'backwash' the unit. The sand in the filter will typically last five to seven years before all the "rough edges" are worn off and the more tightly packed sand no longer works as intended [ citation needed ]. As there is no pressure inside this tank, they were also known as "gravity filters".
These types of filters are not greatly effective, and are no longer common in home swimming pools, being replaced by the pressure-fed type filter. Some filters use diatomaceous earth to help filter out contaminants. Commonly referred to as 'D. As of , several companies now produce regenerative media filters, sometimes called precoat media filters, which use perlite as the filtration media rather than diatomaceous earth. As of , perlite can safely be flushed down the sewer and is approved and NSF listed for use in the United States.
Other filter media that have been introduced to the residential swimming pool market since include sand particles and paper type cartridge filters of 50 to square feet 4. Some of the best examples include:. Some people decry the use of technology to improve sports performance but in reality it is inevitable. The research and development of sport apparatus and apparel is an industry in itself which creates opportunity for investment and employment.
