Electric Swimming Pool Covers

!: Electric Swimming Pool Covers

Why? It cannot be argued that swimming pool covers are an essential addition to any pool. No matter what the weather, you'll want to keep the elements and the debris out of the water, keeping it clean for your family.

Swimming pool covers are heavy - those designed with safety in mind can be especially cumbersome - and easing the process of ravelling and unravelling the large cover may be a priority for many people. Why not opt for an electric swimming pool cover. These electric covers are essentially the same as other covers, but when you want to put them over or drag them off the pool it's as simple as pressing a button.

Who would use them? Electric covers are often popular in public pools where it must go on every evening, and come off every morning - electricity greatly assists this tedious and difficult process.

But they can be used in the home, too. Unlike with standard manual covers, neither strength nor dexterity is required to use electric swimming pool covers. This makes them ideal for elderly or disabled people, especially those that require frequent dips into the pool for therapeutic reasons. If retracting the cover is too much for some people on their own, then an electric swimming pool cover would be an ideal solution.

How do they work? A motorised pole the turns a reel, either pulling the cover in or pushing it out along rails. The electric pole will be versatile enough to fit a range of pool widths and lengths (and should be easily adjusted by the purchaser or the installer) This increases the choice available for those seeking to buy one, as they are not restricted to a particular make or brand that is made specifically for a certain sized pool.

The aesthetics of the cover will often be more pleasing if electric swimming pool covers are integrated into newly built pools, but if the pool is aleady installed and working, a retro-fit version may be your only choice.

This electric, automated action means that electric swimming pool covers are often referred to as "automatic pool covers", since they automatically deploy and retract. The two terms can often be used interchangeably, though it is important to note that by 'automatic' we do not mean that it performs the action without any prompting. While this behaviour is, conceivably, possible, it is not within the standard function of an electric cover.

Some Things to Consider Before Buying a Swimming Pool

!: Some Things to Consider Before Buying a Swimming Pool

Owning a swimming pool is an aspiration for many people. It can provide many hours of family fun. A summer barbecue by the pool can be enjoyed by everyone. However, don't get carried away by the dream. There are several things you need to know of.

First of, swimming pools are extremely expensive. The initial construction will run into thousands of dollars. Many people would love to have an in ground pool. These can easily run into the tens of thousands because of the work involved. But most people forget of the ongoing maintenance costs. You will constantly need to buy new filtration chemicals and be filling it up with water. Because the equipment will be under constant use, it will break down regularly and need to be repaired or replaced. After the spring the water will be especially dirty. Unless you have special equipment (very pricey) it might be best for it to be cleaned by a professional. Many people look at the initial price tag, imagine the fun it will bring and be fine with it. It's the ongoing costs that people don't consider that breaks people.

Second, remember that pools are a lot of maintenance. The water must be constantly monitored and kept clean. You need to change the filters and use an automatic cleaner. I know many people who installed pools in their back yards. They loved it for awhile. But after several years they tired of all the work that needed to be done. Eventually many of them had them removed because they no longer thought it was worth it.

Swimming pools can be a lot of fun. However, look before you leap. Consider both the amount of time and money it will fully cost you before proceeding.

Before 1970, scientific research in swimming was poor and anecdotal, and the improvements of performance were linked firstly to the swimmer's experience and, secondly, as a result of permanent research for speed. Before and after the Second World War, scientific studies were conducted by pioneers and marked the beginning of research in stroke mechanics and swimming physiology exercise. This book reviews research on the body of knowledge available for the improvement of sports coaching and training practice in swimming, which seems to be relevant, numerous, and diversified enough to help swimming coaches bridge the gap between theory and practice.

History of English Channel Swimming

!: History of English Channel Swimming

When thinking about swimming feats, the English channel swim always comes first to mind. At its shortest point, the distance between the English and French coastlines is only 22 miles, but a combination of cold and strong currents mean that only 10% of people who attempt this feat actually make it to the other side.

The first channel attempt was by J.B Johnson, who had to pull out after just over an hour. Three years later, Paul Boyton made it to the other side using a special prototype buoyancy suit. However the first unaided swim went to Captain Matthew Webb, who swam from Dover to Calais in 21 hours and 45 minutes on his second attempt.

Curiously, after this success it was to be 35 years before another was registered, although there were plenty of attempts. One man, Jabez Wolffe tried and failed on no less than 22 occasions, four of them by less than a mile! Thomas Burgess had better success, becoming the second man to swim the channel on is 13th attempt.

The first man to swim in the reverse direction from France to England was Enrico Tiraboschi in 1923 - nowadays France-England is recognised as the 'easy' route because of favourable tides. In 1926 Gertrude Ederle became the first woman to complete the distance.

The popularity of channel swimming reached new heights with the staging of a cross-Channel race in 1950; 20 entrants took part in the inaugural race, 9 of whom finished. In 1972, 15-year old Lynne Cox became the youngest person to swim the channel, breaking the men's and women's speed records in the process, and in 1988 Thomas Gregory swum the channel aged just 11.

To date, over 1200 people have completed this challenge since the first success more than 130 years ago. The team with the record for the most swims is the Sri Chinmoy Marathon Team with now almost forty swims completed by its members. The current speed record is held by Christof Wandratsch in a staggering time of 7 hours and 3 minutes. However, the undisputed channel crossing champion is Alison Streeter, who originally hails from Dover and has crossed the channel 43 times, in addition to setting the first three-way channel crossing - a return journey to Dover and then back to France again! The popularity of Channel swimming is now such that hopeful swimmers must go on a waiting list to secure a boat crew to escort them across.
