I got a lot of replies on that post and would like to comment on some ones.
Alex Y. tennis professional: “It depends also on age and what are they training for. There is not one define answer. It also depends on how athletic the individual is”.
Of course it depends on, Alex. But any organism has its own resource, right? I said that a lot of young tennis players especially in tennis academies train too much, sometimes show very good results and win those who train less. But a few of them play on pro level successively for a long time. Look at Agnieszka Radwanska, she has always cares about herself and she is #4 in the world now. Where all those extremely talented young players like Nicole Vaidišová or Tatiana Golovin who started to play pro level in 14 years old?
Nick Muresan, tennis professional “I have 3 kids. All three kids played with scholarship at NCAA Div.I, two of them played pro circuits. I never train them more then 1 1/2h /day, except Sunday.I will say , 10 hours a week of intensive and quality practice, will be enough for a junior not to get burned out, and still to love tennis”.
Nick, you just confirmed the opinion that talented kids show very good results with 10 hours training a week of very qualitative training process. Good luck for your kids Nick.
Diana Chalikov, fitness professional: “I believe 15 hours a week combined with 5 hours a week of strength training off the court. Off court exercise is also very important to develop muscles that are otherwise not engaged during regular practice, but will be helpful during tournament play. Plus one day off to reboot”.
Diana one more time concentrates our attention on a very important factor in tennis player development – specialized tennis fitness. Thank you for your point.
Lester Yesnick, tennis professional “It is the quality of training, not the amount that is most important”.
Lester has the same opinion as John Evert, who said in his interview “Quality over quantity”.
I am very thankful for your comments and hope that readers of the blog will find them helpful for organization training program of junior tennis players.
