The older players have dominated on the women's side in recent years. I think the younger players don't really learn the discipline necessary to be successful until they have been on tour for a while. The younger women like Bouchard are making extraordinary sums of money at a young age and enjoying clubs and shopping. It takes a while for them to become disciplined professionals. A few years ago there was a Chinese player who in her 30s jumped into the top 10 and won a major or two. She then suddenly retired. It's a difficult grind for these women as it takes a lot of hard work to become and remain a top pro.
On the men's side Wawrinka emerged as a top pro at age 30. He was a journeyman player for a long time but worked very hard on his game and became a top pro. He has even won a few majors. This is a trend now in tennis which at one time was dominated by young stars on both sides. It's all the money and the physical demands of the tour. Bouchard is like many other young players who flash potential but then battle these things, conditioning and injuries while also trying to enjoy life.
Regarding Wawrinka, he is a seriously fit man and uses his fitness to outlast opponents. Bjorn Borg was like this when he played. His fitness was better than anyone's and his legs were incredibly well defined. McEnroe once said he was the fittest player he ever saw.
