Swimming offers something no other aerobic exercise does: the ability to work your body without harsh impact to your skeletal system. When the human body is submerged in water, it automatically becomes lighter. When immersed to the waist, your body bears just 50 percent of its weight; dunk yourself to the chest and that number reduces to around 25 to 35 percent; with water all the way to the neck, you only have to bear 10 percent of your own weight. The other 90 percent is handled by the pool.
This means that the pool provides an ideal place to work stiff muscles and sore joints, especially if you're overweight or suffer from arthritis.
In its recommendation for the right types of exercise for people with arthritis, the Arthritis Foundation suggests those that stretch muscles, those that strengthen muscles, and those that provide an aerobic workout. A few laps in the pool combine all three!
If the pool is heated, so much the better for arthritis sufferers, as the warm water can help loosen stiff joints. In fact, people with rheumatoid arthritis receive greater benefits to their health after participating in hydrotherapy than with other activities. It's also been proven that water-based exercise improves the use of affected joints and decreases pain from osteoarthritis [source: CDC].
Swimming is also a great way to increase muscle strength and tone. Have you ever seen a flabby competitive swimmer? Yea I didn't think so. For example when you are running you are only moving your body through air, but when swimming you are propelling yourself through water, which is about 12 times as dense as air. So every kick and arm stroke become a resistance exercise. Resistance exercises are the best way to build muscle strength and tone. Swimming has also been proven to help increase bone strength.
Unlike doing a machine exercise in a gym where you are only working one body part at a time, swimming is working your whole body at once. You are increasing your flexibility while swimming through water as you are stretching your whole body all at the same time.
In addition to helping tone the visible muscles you are also building up your cardiovascular health. Because swimming is an aerobic exercise you are increasing the strength of your heart. You are making it more efficient in pumping which leads to better blood flow throughout your body. The American Heart Association reports that just 30 minutes of exercising a day, such as swimming, can reduce coronary heart disease in women by 30 to 40 percent.
Swimming is one of the biggest calorie burners out there. So it is great in helping keep your weight under control. The exact number of calories you burn is based on your own physiology and the intensity in which you are swimming. A general rule is, however, for every 10 minutes a breast stroke burns 60 calories, backstroke 80 calories, freestyle 100 calories, and the butterfly 150 calories. That sounds fantastic right? To boost those calories try intervals. Work hard for short bursts then recover. Go all out for 50 yards then rest for 10-15 seconds, then repeat. You will be tired at the end, but will have burned a lot of calories. Make sure you refuel with healthy snacks and plenty of water afterwards.
There is also research that shows you can help lower your cholesterol, help control asthma symptoms, lower your risk of diabetes, and help lower stress. So it sounds like one of the perfect exercises right? So get out and swim swim swim!! Your body will thank you.
