A group of older ladies meet in the warm water pool every week at the same time on Tuesdays, Thursdays and Fridays. They are all post-therapy patients who are not quite up to the rigorous aqua aerobic classes that the club offers, but they no longer meet 3rd party payer requirements to work with an aquatic physical therapist. And while many have forgotten the exercise routines that their therapists recommended, they are still drawn to the water. A couple of them walk laps, a few bob on noodles as they scissor their legs, and some just hold onto the wall and chat. By all appearances, this is just another social support group. But why meet in the water?
When you immerse yourself in water, the pressure produced by gravity in the water (hydrostatic pressure) provides resistance to the diaphragm from all sides, strengthening this important muscle for breathing. Resting heart rate decreases and you burn more calories. The tissues around the joints relax when underwater and joint pressure lessens. The heat of warm water helps muscles relax and relieves pain.
And add exercise and movement~ and the benefits multiply. Studies show that obese women burned 35% more fat calories exercising in the water than on land. Hydrostatic pressure offsets lower body swelling that sometimes comes along with exercise. The relaxation of muscles allows you to stretch further than you can on land. The water resistance as you move through the water challenges core and extremity muscle strength, balance and endurance. With the decreased effects of gravity in the water, muscle fatigue is postponed and you can exercise more efficiently. At shoulder level, 80% of the effects of gravity are relieved, so even someone with lower extremity joint problems or weight bearing limitations can enjoy the benefits of water. What better place to be?
