A good follow on to this study, along the lines of tennis, would be how the introduction of polyester strings to the pro game about 20 years ago [1] impacted the game, for younger and older players - to see if similar conclusions can be reached. For myself as an older tennis player with a well developed game, I had a much harder time adjusting to this newer type of strings than many younger players. Even though the theory and what had to be done made sense, overcoming muscle memory and ingrained habits proved very difficult - of course I'm just a sample size of 1.
