Swimming - Hi

Swimming is a good form of exercise. Because the density of the human body is approximately similar to that of water, the body is supported by the water and less stress is therefore placed on joints and bones. Therefore, swimming is frequently used as an exercise in rehabilitation after injuries or for the disabled. Resistance swimming is one form of swimming exercise. It is done either for training purposes, to hold the swimmer in place for stroke analysis, or to enable swimming in a confined space for athletic or therapeutic reasons. Resistance swimming can be done either against a stream of water set in motion by a (usually) self-contained mechanical device (often termed a swimming machine) or by holding the swimmer stationary by means of elastic attachments. Swimming is primarily an aerobic exercise due to the relatively long exercise time, requiring a constant oxygen supply to the muscles, except for short sprints where the muscles work anaerobically. As with most aerobic exercise it is believed to reduce the harmful effects of stress. While aerobic exercises usually burn fat and help with losing weight, this effect is limited in swimming, even though being in cold water burns more food energy to maintain body temperature. The reason that swimming does not significantly reduce weight is still poorly understood, but seems to be related to the better heat conduction of water. A number of reasons are suspected. Water cools the body much faster than air and most researchers believe that subsequently the body aims to maintain a layer of fat under the skin for insulation. It is believed that appetite decreases as the body temperature increases, as for example during exercise. However, during swimming the body is cooled down almost instantly as the surrounding water is usually cooler than the body temperature, and some researchers believe that this may actually increase the appetite. This assumption is not yet proven by research. Fast swimming requires a high level of effort, meaning glycogen rather than fat is burned. Prolonged exercise at lower intensity is better for fat-burning. Some researchers also believe that the metabolism of the body increases at higher body temperature, burning more food energy. Again, during swimming the body is cooled down by the surrounding water, reducing the metabolism, and subsequently the amount of food energy burnt. This assumption is also not yet proven by research. There is also a theory that people with a genetically higher body fat content tend to be more successful as swimmers since the increased buoyancy of the fat aids in floatation or the rounder shapes offer less resistance to the water. Swimming exercises almost all muscles in the body. Usually, the arms and upper body are exercised more than the legs. In competitive swimming, excessive leg muscles can be seen as a disadvantage as they consume more oxygen, which would be needed for the muscles in the arms, although this depends on the swimming style. While breaststroke generates significant movement with the legs, front crawl propels the body mainly with the arms. Sometimes the swimming consists of swimming laps using a conventional stroke, such as the front crawl; other forms can include different forms of exercise performed in the water, such as water aerobics. Swimming may be good for asthma sufferers. Swimming uses all three energy systems, which are the creatine phosphate system, anaerobic glycolysis (also known as Lactic acid system), and the aerobic system. These three systems require energy in form of ATP to function.

Swimming is great exercise for me and is also very fun to do during the summer or throughout the year depending on where you live and if you have any indoor pools. I love it a lot and wish that I had a bigger home and had a pool with it.

I love to swim. I have started swimming when I was 8 years old. My friends taught me how to swim. However, they were not good teachers though they can swim well. What they did to me is they told me to swim halfway of the pool while they hold my legs, in case I panic. What they did to me is they let go of my legs but I didn't know they were already far. I was swimming by myself that time and when the time I want to take a breather, I noticed that no one was with me, I panicked and I nearly drowned. My friends were laughing, but they dived in and rescued me. I beat them to pieces after that.

that was an interesting piece of info vinay and thank you for that. i was long distance runner and capable of lapping up 7 kms in less than 18 mins on an average but i found that i wasn't able to swim even for 500 metres without a break. even plain floating isn't possible for more than 2/3 mins and rush to the shore. i have been in 'troubled waters' in the sea and at those times i have managed to come out safe. but why is that when i can run half and full marathons comfortably, i wasn't able to measure up to this water sport ?
