Which is better for speed: salt water or a chlorinated pool?
On One Hand: Salt Water is More BuoyantSalt water is almost 2 lbs. heavier per cubic foot than chlorinated water. This makes salt water more buoyant than chlorine water. The increased buoyancy will make an overwater swimmer faster, according to Marietta College.On the Other: Chlorinated Water Causes Less ResistanceCompared to chlorine water, denser salt water may slow a swimmer underwater. The increased density requires more work to traverse, explains Tara Koff, Eddy Matkovich and Kristin McPhillips of the University of North Carolina.
