Exercise in the water puts very little strain on the bones, joints and soft tissues while still allowing for high levels of energy expenditure. The buoyancy and cushioning effect of water is especially beneficial to people at risk when performing weight-bearing exercise such as the elderly or obese. It may help with pain management for individuals with soft tissue injury, rheumatoid arthritis, osteoarthritis or orthopedic disorders.
Exercising in the water decreases the amount of weight the spine and joints have to support. The buoyancy of water supports about 50 percent of body weight for a person immersed waist-deep and 90 percent of body weight for a person immersed up to the neck.
Exercising in water offers many physical and mental health benefits and is a good choice for people who want to be more active. When in the water, remember to protect yourself and others from illness and injury by practicing healthy and safe swimming behaviors.
