Former Czechoslovak and later American tennis player. She is considered one of the best tennis players of all time, who holds the absolute record for the number of tournaments won among tennis players.
Six weeks before her 50th birthday, she won the US Open (the last of four top-tier tennis tournaments). One of her key successes is a plant-based diet, of which Navrátilová is a supporter.
“I am sure that the shift in my diet to a plant-based diet was the main reason why I was able to play tennis at a professional level even after my forties. Thanks to it, my mind is sharper and I can withstand the training load.” (Source: soucitne.cz)
