What is swimming and why is it important?
Swimming is a form of whole-body exercise, using most of the main muscle groups in the body and helping to strengthen cardiovascular health. Considered one of the least impactful physical activities, swimming is suitable for obese people because it reduces pressure on joints and burns calories effectively. Swimming not only supports weight loss but also brings many other health benefits, helping to improve muscle strength, increase flexibility and improve endurance.
Benefits of swimming for weight loss and obesity
Burn calories effectively
Swimming is an effective calorie burning exercise. A person weighing about 70 kg can burn 400–600 calories in an hour of moderate intensity swimming. For obese people, calorie burns can be higher due to larger body mass, which makes swimming a great option for weight loss.
Boost metabolism and reduce body fat
Swimming helps increase basal metabolic rate (BMR), helping the body burn more calories even when resting. Research from the Journal of Exercise Rehabilitation shows that regular swimming can help reduce body fat, especially visceral fat, thereby improving body composition.
Less impact on joints, suitable for obese people
One of the biggest benefits of swimming is that it has less impact on joints. Water supports body weight, helping to reduce pressure on joints. This is especially important for obese people, who are at high risk of joint pain and injury. Research from Archives of Physical Medicine and Rehabilitation shows that swimming can improve joint function and reduce pain in obese people.
Improve cardiovascular health
Swimming is an aerobic exercise that helps strengthen cardiovascular health, reduce blood pressure and improve respiratory function. A study in the American Journal of Cardiology shows that regular swimmers have a lower risk of cardiovascular disease than those who are less active.
Reduce stress and improve mood
Swimming helps relax the body and stimulate endorphin release, thereby reducing stress and improving mood. A study from the International Journal of Stress Management shows that swimming can help reduce symptoms of anxiety, depression and improve quality of life.
