Pool pull
Question: The density of saltwater is higher than that of freshwater, so
swimming in saltwater should be marginally faster than in freshwater because
swimmers are carried slightly higher in the water and suffer less friction.
Given the split-second timing of world records, are the water densities of
the various competition pools measured and controlled in the same way that wind
speeds for athletic track events are kept within limits?
Answer: It is a misconception that the higher you are in the water, the
faster you can swim. On the contrary, the highest speeds are reached by swimming
completely…
