BENEFITS OF SWIMMING

Introduction
Swimming is an activity that burns lots of calories, is easy on the joints, supports your weight, builds muscular strength and endurance, improves cardiovascular fitness, cools you off and refreshes you in summer, and one that you can do safely into old age. By the 20th century, swimming had become mainstream. Indoor pools were beginning to appear, most towns with populations over 20,000 had public outdoor pools, and swimming clubs became increasingly popular for recreation. Women participated for the first time in swimming in the Olympic Games in Stockholm in 1912,and Johnny Weissmuller(considered by many authorities to be the greatest swimmer of all time and who later went on to Tarzan fame in movies)became the first person to swim 100 meters in less than one minute. Today swimming is the second most popular exercise activity in the United States, with approximately 360 million annual visits to recreational water venues. Swim clubs, recreation centers, Y’s and many other facilities feature swimming pools. Many high schools and colleges have competitive swim teams, and of course, swimming is one of the most popular Olympic sports. Millions of Americans are swimming each year.

Benefits of Swimming
Low Impact
There’s no ground impact when you swim, and so you protect the joints from stress and strain. In fact, the Arthritis Foundation strongly recommends swimming and water activities for this reason, so much so that they sponsor water classes all over the country. Water aerobics classes are also desirable for this reason, because even if you do jump and hit the bottom of the pool, you do so with less force because you’re buoyant in the water. Not only that, but if you wear or hold a flotation devise during a water aerobics class, the impact is even less.
Builds cardio respiratory fitness
Swimming improves endurance. In one study of sedentary middle-aged men and women who did swim training for 12 weeks, maximal oxygen consumption improved 10% and stroke volume (the amount of blood pumped with each beat which indicates heart strength) improved as much as 18%.

Builds muscle mass
In a study of men who completed an eight-week swimming program, there was a 23.8% increase in the triceps muscle (the back of the arm). My take on muscle mass and swimming is that if you have been doing no resistance exercise at all and you start to swim, you will certainly get more toned and you may even gain mass like the men in this study. But even without the gain in mass, its well worth the strength and tone that you will almost certainly gain.
An alternative when injured
When athletes are injured, particularly in the lower extremities, they are frequently told to swim to maintain their fitness level. Swimming helps them stay in shape, and it’s even part of the rehabilitation. That’s because the resistance of the water makes the muscles work hard without the strain or impact that is experienced in land. It’s a break from the summer heat
There’s nothing like it during the hot days of summer, whether it’s at the beach or in the pool. It’s relaxing, the movements are smooth and rhythmic, and it’s a great workout.

It’s a family affair
Swimming and other water activities are something the entire family can share. With rising levels of obesity in children as well as adults in the United States, family physical activities and good role-modeling may be one way to stem the epidemic of inactivity and obesity facing our nation.
Burns calories
Swimming burns lots of calories, anywhere from 500-650 per hour depending on how efficiently you swim (you burn more flopping around than swimming cleanly!) and how buoyant you are (the more body fat you have, the more you float and the fewer calories it takes to swim). Very early and original research on swimming and calorie expenditure showed that swimming, regardless of the stroke, burned about 89% of the calories burned during running and 97% of the calories burned during cycling for the same time period. Stated another way, swimming burns about 11% fewer calories than running but only 3% fewer calories than biking. One important caveat about this data is that calorie expenditure is dependent on the intensity of exercise, and so it’s entirely possible to burn more calories swimming than running in the same period of time as long as you swim hard enough, and particularly so if compared to running at light intensity.
Conclusion
Swimming is an activity that builds strength, endurance, and muscle tone. It’s an activity that you can do all year long, inside or outside, it burns lots of calories, you can share it with your family, it’s low-impact (just in case your bones are creaky), and you can do it until you’re 100!
Swimming is a low-impact form of exercise that’s easy to the joints builds cardiorespiratory fitness and muscles mass, and is an excellent way to maintain fitness during rehabilitation for an injury. Swimming is not recommended for children under 4 years old.
