Benefits of Swimming for Weight Loss
Losing weight requires you to burn more calories than you consume. The American College of Sports Medicine advises performing at least an hour of moderate-intensity exercise five times per week to encourage weight loss. U.S. Masters Swimming notes that swimming is a fun, healthy and challenging form of exercise appropriate for all fitness and experience levels. In addition to helping strengthen your heart, improve flexibility and enhance your mood, swimming encourages weight loss.
A pound of weight is equivalent to 3,500 calories, so to lose pounds you must create a calorie deficit. Physical exercise, particularly cardiovascular work that makes your heart beat faster and that utilizes the large muscles of the body, is recommended to help you create a greater daily calorie burn. An hour of swimming for a 160-lb. person burns about 500 calories, per the Mayo Clinic.
The American Council on Exercise notes that the buoyancy of water reduces your "weight" by approximately 90 percent. The result is a significant reduction in stress on the hips, knees and the back. People who find traditional calorie-burning activities like running, kickboxing and dancing too jarring can still raise their heart rate and burn calories. Obese people may find swimming much more comfortable than work on fitness machines, which involve impact and may not accommodate the size of their bodies.
Builds Lean Muscle Mass
Water provides 12 to 14 percent more resistance than air. The act of swimming -- kicking and moving your arms against the water's resistance -- helps build lean muscle mass and improves your overall body composition. Lean muscle mass is more metabolically active than fat tissue, and thus, you burn more calories when at rest. Adding hand-held buoys, noodles and kickboards to your swim increases the muscle-building effects of swimming.
Even if you do not know how to swim, a pool can help you get an effective calorie-burning workout. Deep water walking burns more calories than walking on solid ground because of the resistance of the water. Water fitness classes also provide an opportunity to exercise in a group setting, without the impact of traditional aerobics. Group exercise promotes adherence, camaraderie and calorie burn.
