Tennis great Martina Navratilova has posted her thoughts about the tennis calendar and its effect on players. You can read the article on Newsweek.com.
When I won my 18 Grand Slam singles titles between 1978 and 1987, I was the fittest woman in tennis, but the global circuit was far less developed, and there was not the demand to play every week of the year. Even then the tour was too long. After 1989, the only way I could get the physical and mental break I needed was to stop playing in the Australian Open and start the tour in February. Today’s athletes can’t do that.
She was indeed the most fit woman on the tour and if she couldn’t handle a tour that was less demanding and with fewer required tournaments, it does beg the question: why the heck should we expect the current players to?
