Swimming is one of the most popular recreational activities in the world. But swimming is far more than just a sport.
While swimming is a potentially lifesaving skill and a great physical fitness activity, it also can be a tremendous source of fun, a rehabilitation tool, a confidence builder for kids, a lifetime hobby or an ultra competitive sport.
And the good news is you don’t have to swim laps to reap the benefits of swimming.
“There are a wide variety of health and fitness benefits of swimming or physical activity in water,” says physical therapist Basil Strasburg, PT, of Cleveland Clinic Rehabilitation and Sports Therapy.
Swimming also is one of the few physical activities that kids can enjoy without feeling as though they are working out in a structured setting, such as a weight-lifting session at the gym or a dance aerobics class. Playing water games with friends, racing, retrieving rings and other games put kids through a workout that few other forms of exercise can rival.
“So it’s a great way for kids to stay active and be more fit,” he says.
Total core training
One aspect of swimming that makes it a great form of exercise is that when you swim, you are using practically your entire body.
As swimmers propel themselves through the water, the arms pull and the ligs kick against the resistance of the water. Meanwhile, the hip, back and abdominal muscles stabilize the head, trunk and spine, providing a total body work out.
Because water is denser than air, every kick and arm stroke is a resistance exercise, which is the best way to build muscle tone and strength.
And, as an aerobic exercise, swimming strengthens the heart and lungs while promoting better blood flow throughout the body, Mr. Strasburg says.
“Swimming is a total-body sport,” Mr. Strasburg says.
Low-impact training
Unlike running and jumping activities, swimming is minimally stressful on the body’s joints. There’s no ground impact, so your joints are protected from stress and strain, Mr. Strasburg says.
In addition, your body becomes lighter when submerged in water. A body in water up to the chest bears just 25 percent to 35 percent of its weight. When immersed to the neck, the body bears 10 percent of its own weight. The water handles the other 90 percent.
The lack of wear and tear on the body is what makes swimming an excellent form of exercise for young children as well as older adults. Swimming also provides a great form of rehabilitation for injured athletes.
Injuries in swimming
Injuries occur far less often in swimming than in most land sports, but injuries do tend to increase as athletes get more competitive. Shoulder injuries are the most common among swimmers.
“Sports that demand overhead motions, such as baseball, tennis, gymnastics or swimming, can put an athlete’s shoulder through the same motion over and over,” says Paul M. Saluan, MD, Director of Pediatric and Adolescent Sports Medicine at Cleveland Clinic. “This can place significant stress on the shoulder, leading to overuse injury.”
Shoulder pain, often called swimmer’s shoulder, is common, Dr. Saluan says.
Overuse of the rotator cuff muscles, scapular muscles and muscles of the upper and lower back can cause pain from fatigue and lead to tendonitis or bursitis. In more severe cases, dislocations or rotator cuff tears are possible, though not common, Dr. Saluan says.
Knee injuries, known as breaststroke knee, can occur when the legs extend and are brought back together during the push-off phase of the kick. This motion puts the inner ligament of the knee, called the medial collateral ligament), under stress, Dr. Saluan says.
