Great Britain's Fed Cup captain Judy Murray has called for a heat break to be introduced in the men's game amid concerns over high temperatures at Wimbledon.
Female players can call for a break after two sets when playing in hot conditions, but there is no provision for a similar interval in the men's game, despite male players competing over five sets at the Grand Slams.
"I think the men should adopt it as well, especially because they have to play five sets," BT Sport quotes Murray as saying.
"And a slam is such a tough thing to play in, I know you get a day in between matches but if you're going to win a slam you need to play seven matches in 13 days.
"And for the men working across the best of five sets it's incredibly physically and mentally draining, so I think the men should take advantage of it as well."
Murray was at Centre Court to watch son Andy Murray defeat Mikhail Kukushkin in straight sets in the first round yesterday.
