A number of factors go into speed.
One is resistance, or streamlining to minimize resistance.
One is strength.
One is reaction time.
One is intensity.
I can be the best swimmer in the group and no where near the fastest. I'm older than most of my teammates. I keep trying to recruit more of us old timers, with little luck. I never competed when I was young, so I don't have the intensity of my peers.
