"I know now it is down to conditioning, hydration or food related" - Murray on cramping issues

Andy Murray suffered from cramping issues in the past few weeks derailing a couple of promising performances from the Brit.

It was most recently a problem in Cincinnati where the Brit almost beat Cameron Norrie in two sets before he started up cramping and losing the match. He did some tests and speaking before new york admitted there is nothing wrong:

"The sweat test was good, blood test was good. No illnesses. I know now it is down to conditioning, hydration or food related."

It's a positive result for him because he knows that everything is fine and feels in pretty good shape heading into New York:

"I feel like I am in decent shape, so that is why it is concerning. The results of tests were positive news but I don't really know why it is still happening."

He will pay more attention to what he eats and drinks before matches to try and figure out the possible cause:

"Usually I am pretty precise and good with it, but it is a fine balance to make sure you're getting the right fluids when you're on court," said three-time major champion Murray. I take litre-and-a-half bottles on to the court to make sure I'm drinking enough at the appropriate times. In these conditions I always try to drink a litre and a half of my sports drink in 40 minutes."

And continued:

"But if you have two games which last for 15 or 20 minutes then it is difficult to make sure you're drinking enough. If you take on too much you can feel bloated. The last few days in practice I have actually felt a bit better in the conditions, so hopefully I will be all right on Monday."
