Andy Murray has revealed that he will go through sweat testing in an attempt to solve his recurring cramping issues ahead of the US Open.
The former world No 1 will be unseeded going into next week’s tournament, meaning that he could potentially face an opening round clash with some of the competition’s leading contenders.
The 35-year-old has overcome a number of career-threatening injuries in the last few years, yet he has suffered from cramp since arriving in the United States last month.

However, Murray has revealed the extents that he is set to go to in order to try and solve the problem before the tournament’s start date on Monday.
He said: ‘I’m doing sweat testing in these conditions to see if anything has changed in that respect because the sports drinks and the electrolytes is made specifically on my sweat tests, but I haven’t done sweat testing for quite a number of years.
‘I don’t know if anything has changed in that respect but we’ll try and get to the bottom of it.

‘Because let’s say if it was purely from hydration, then obviously after I got cramp like in Washington I made sure that I was not dehydrated going into the next matches.
‘And if it was eating related then I made sure all of those boxes were ticked. It’s not just been as simple as changing how much I’ve been drinking or what I’m drinking so I need to get some answers.’
Murray has failed to claim an ATP title this year for the first time since 2019 – despite reaching finals in both Sydney and Stuttgart.

The 35-year-old is also attempting to reach the second week of a Grand Slam for the first time since 2017 in New York next week, yet the Scotsman does believe that the tournament is the ‘most open’ it has ever been.
He added: ‘I would imagine some of the guys who you would expect to go deep, will do. [Daniil] Medvedev, Rafa [Nadal], [Carlos] Alcaraz and [Stefanos] Tsitsipas – these guys.
‘I do think there will be an opportunity for Cam [Norrie]. He’s been very consistent against the guys ranked beneath him for the most part this year.
‘He’s definitely got a chance of a good run. When it’s hot and humid that can help his game and the courts here are quite fast.’
He added: ‘Physically I feel pretty good in terms of discomfort and pain and everything but then I’ve been having the cramping the last few weeks so that’s been frustrating.
‘I’ve had cramp before but not consistently so I’m just trying to understand and get to the bottom of that.’
