Hydrostatic pressure from immersion in water forces more blood to the central organs, increasing cardiac stroke volume and cardiac output, which is a similar effect caused by exercise. In addition, immersion also impacts liver and hormone production (endocrine system) and respirator exercise to breathe against the pressure imparted by the water. As with any exercise, […]
It’s not just about cloudy water. Ten years ago the term Recreational Water Illness (RWI) was not even a commonly used term.

If you read the papers (or Internet), you would think the aquatics field is all about death and pain. The exception is during an Olympic year when we witness some amazing athletes in bathing suits. I have the privilege and blessing to speak to groups around the world. Most people in the pool and spa […]
Two-thirds of Americans are afraid of deep water in lakes, rivers, and oceans A study performed by Gallup (n-815) and presented at the 2008 World Aquatic Health Conference (Melon Dash) indicates that 64% of Americans are afraid in the deep, open water (lakes, rivers, oceans, etc.) Forty-six percent are afraid in deep water in pools. Even […]
My recollection of Coach Vornbrock is during a swim meet in the 1950’s when he is walking along the pool deck, carrying a stop watch, wearing the obligatory white shirt, white trousers and white tennis shoes. Ernie, who was in his 50’s, was a tall lanky man who wore wire rimmed glasses on his angular […]
