This weekend I’m playing in my first junior tennis tournament and I really need some tips and ideas on how to stay calm and relaxed during the matches. Please help.
There will be a best answer given out.
i play a ton of tennis, its my life pretty much so i hope that i can help you! if you’ve had any serious injuries in the past make sure the ice them the night before- drink lots of water, but not TOO much. gatorade/powerrade/vitamin water are the best liquids to drink while on the court. dont get worked up if you miss a shot and dont get over confident if you make a really good shot- tennis can go well as easily as it can go bad- focus – keep your eye on the ball and don’t let your opponent intimidate you! if you have trouble keeping calm take a really deep breath also- make sure when warming up with your opponent you just try to be consistent- don’t waste all your energy in the first five/ten minutes of the match! just hit like your hitting with a friend or somethhing! warm up your serves slowly and then hit ‘em hard! its about progression! one more thing- if your parents or friends and family are watching, don’t look at their reaction after ever shot, it just doesn’t help! concentrate on the court, the ball, and that’s it!!! dont’ take too much water in during breaks
p.s. GOOD LUCK!
