A Brief Look At The History And Science Of Swimming

Swimming has been around as long as people have been on earth and where ever there is water people are going to be swimming. It was first done in Egypt and then just started getting more and more popular and we have the sport as we have it today. Many people didn't think that swimming started until the 1900s well at least competitive swimming anyways.

The water and liquids in your body are not denser the water because then you wouldn't be able to float and swim. This is what allows you to swim is all your insides being lighter then the water which allows your body to get to the surface if your liquids were denser then water then you wouldn't float you would sink and that wouldn't be swimming.

When you are swimming your body should be straight with the water other words known as parallel to the water. You are going to want to try and stay afloat and try to move your arms and start swimming if you are a big guy with a lot of muscle it is going to be harder for you then for someone that is skinny and with only a little bit of muscle because they are going to be like a fish small but still able to force themselves through the water.

Your hips act like your rudder or speed because the more hip muscles you have the faster you are going to go because of simple propulsion. You are going to be moving through the water fast if you swim correctly. With your arms moving and going forwards with your hips moving you are going to be moving at a good pace.

You should be able to swim fast if you are a swimmer and if you cannot them you are not a good swimmer. Swimmers that compete are swimmers who have been swimming their entire lives and are the ones who actually know how to swim with ease and good. You are going to want to use as less oxygen and force as possible so you can have speed breaks and go for sprints when you are swimming. If you give it all you got at the start then you are not going to be able to finish very well. The trick is to be able to keep up with all the other swimmers then at the last stretch you just cut loose and sprint with your swimming to the end.

The slicker your skin is with the water the faster and easier you will move through the water that is why you always see swimmers with those funny hats on because it makes their hair flat so that they can fly through the water at good speeds. If you are a swimmer and you love to compete then you need to get some of this kind of gear so that you can go faster while swimming.

 


Benefits of Installing An Outdoor Sauna

There are many benefits to installing a sauna. Whether you decide to install one for health reasons, or just for the pure enjoyment and relaxation, justifying such a purchase should not be difficult.

There are also several types from which to choose. Where you install your sauna will most likely depend on the amount of space you have, and how much of it you can devote. You have two basic options when doing so, an indoor sauna, or an outdoor sauna. There are advantages to both, but installing an outdoor sauna may present you with more options.

There is currently a wide variety of pre-fabricated sauna kits available today, and many options where type and size are concerned. Since many outdoor saunas are also designed to be a pool house, you can own both in one unit. This can help take care of your pool needs in the summer, while providing you with the use of a sauna year-round.

Here, you will have a changing room that is separate from the rooms in your house, which will offer guests privacy at the pool area. This can also help to extend your pool season by allowing you to enjoy the heat of a sauna, and then cool down in the pool.

Most of the pre-fabricated kits are designed for easy assembly, and include all the parts you will need to build your outdoor sauna. The kits also come with detailed instructions that will help you along the way. It's quick and easy.

Another benefit of having an outdoor sauna verses an indoor one is the money you can save. If you wish to add a sauna to your home, the cost will dramatically increase, and you will probably have to hire a contractor to do the job unless you are able to do it yourself. By purchasing a pre-fabricated sauna kit, you will be able to build it yourself. Even if you decide not to purchase the kit and just build one from scratch, it can still save you money in the long run.

Another benefit of owning an outdoor sauna is the privacy it will give you. If your sauna is connected to your house, you do not have to leave the building to enter it. You will still be subjected to the noisy activity taking place in your house, and probably won't get the peace and quiet you need to relax. By installing an outdoor sauna, you will be able to enjoy the time you will have to yourself in a quiet, peaceful environment.

 


Pool Solar Heater vs Gas Heaters

A new gas powered heater for your swimming pool will cost upwards of $3000 or more, and heating the pool in this fashion can cost many more hundreds on a monthly basis, so switching to solar heat for your pool may be the best financial option. All you need in order to install a basic solar heating system on your swimming pool is an area relatively close to the pool that is approximately half the square footage or more of the surface area of the pool. This area must be in direct sunlight for the majority of the day in order to realize the full potential of your pool solar heater.

The actual amount of surface area that you will need to cover with solar cells will depend on the size of your pool, howl warm you want the pool to be, as well as the amount of direct sunlight that that area receives. It will also be critically important whether you use a cover nightly on the pool. Without a cover nightly on the swimming pool almost all heat generated from the solar heater will be lost.

Manufactured solar panels are more efficient per given area then most homemade solar heaters. Mostly this boils down to surface area contact between the water and the heat exchanger itself. Manufactured solar heaters for swimming pools take the water from usually a 1.5" pipe and reduce it down to one quarter of an inch or less. Most homemade solar heaters use half inch or 3/4 inch pipe at the least. The more surface contact area the water has with the heated source, the greater the effectiveness of the solar heater.

You can either build a solar heater from scratch or you can buy a manufactured solar panel to heat your pool. Usually if you buy a manufactured product you will need to buy multiple solar cells in order to heat your pool. The amounts of cells that you will need will depend on the size of your pool and the solar panels that you are buying will have this information.

Alternatively you could build your own solar heater out of ABS, PVC or copper pipes. All you need to do is run a grid of plumbing on a hot surface such as a shingle roof. The pipes should be small in diameter to increase the surface area contact with the heat exchanger. In this example the surface of the pipes themselves are the exchanger as the heat from the sun keeps the inside of the pipes well the water on the inside absorbs that heat.

To install the system you will need to tap into the existing circulation system for the pool. You would attach the pipes into the circulation system so that you remove water after it has been filtered to ensure that larger debris does not get stuck in your solar heater. It would also be a good idea to add any chlorine that you are adding to your system after the water as has been heated to avoid sending concentrated chemicals through the heater itself. By adding valves such as ball valves, you can achieve control over the amount of water that you are sending at any given time. This will also allow you to turn off the solar heater altogether as well as provide a point for drainage should you need to winterize your system.

Many solar heaters are installed as a part of a control system that uses either temperature or the time of day to turn on and off the heater. It is not a good idea to cycle water through a solar heater if there is no sun as this will actually reverse the process stealing heat away from the pool. Mechanical actuators are added to the isolation valves which achieve a level of automation. This can be controlled through timers or by manually adjusting the settings for your control system.

It is important to note the limitations of pool solar heaters in that they do not prolong the swimming season. A gas-fired heater can extend your swimming season up by a few months however solar heaters will not do this. They are simply not powerful enough to overcome the cold temperatures however they do make mid season swimming much more enjoyable.
