How does science contribute to cycling, tennis and basketball?
I don’t know about basketball, but tennis has improved racket design, new materials etc, compared to the wooden rackets they used to use back in the days. Cycling, at the pro level, they not only have new bike design, the suits are designed to reduce drag. The rider would ride a stationary bike inside a wind tunnel to improve his form. Out of the 3 I think cycling has improved more with technology.
