Resistance and Viscosity
What are Resistance and Viscosity, and How Do They Affect Water Exercise?
Resistance actually occurs between the molecules of a liquid, effecting how a liquid flows. Viscosity can be thought of as a measure of a fluid’s resistance to flow. Liquids of high viscosity, such as syrup, flow slowly.
Liquids of a low viscosity flow fast, such as mercury. Water is 790 times more viscous, and provides twelve times the resistance than the air normal exercise is performed in. The density of water is approximately 1,000 times greater than air.
