Water’s buoyancy lessens the effects of gravity on your body. In essence, your weight is reduced when you are in water. Depending on how deeply you are immersed in water, you can significantly reduce the amount of weight your body bears. When waist-deep in water, your body only has to handle approximately 50 per cent of your body’s mass weight; in neck-deep water, only 10 per cent.
Buoyancy also decreases the amount of shock absorbed by your bones, muscles, joints and ligaments. When swimming in deep water, your body suffers virtually no impact at all.
This makes water-based fitness programs ideal for individuals who have difficulty moving on dry land. Swimmers who are overweight, elderly or suffer from ailments such as arthritis, fragile bones, injuries or other disabilities, can all benefit movement in the water. Special lifts and other accessibility equipment is even available to help these bathers get into the pool.
