Organisers have unmasked a”more extensive” Extreme Heat Policy after temperatures from the shade approached 40C throughout the 2018 tournament.
A 10-minute fracture was in place for women’s and junior singles, and a fracture for wheelchair singles.
January, the Australian Open gets under way in Melbourne on 14.
Tournament director Craig Tiley claimed that the health of players was the”utmost priority”.
Under the new policy, even when a reading of 4.0 is recorded on the Australian Open Heat Anxiety Scale within a men’s singles match, then a 10-minute fracture will be allowed after the next group.
If the reading does occur within a women’s or singles match, this break will take place between the third and second collections, and also will the 15-minute break in wheelchair singles.
If a reading of 5.0 is recorded, the championship referee can suspend play.
Other variations to this policy for 2019 include broader measuring of an upsurge and weather conditions in measuring apparatus.
“The AO Heat Anxiety Scale takes advantage of the latest clinical study into the effects of heat to the human body including the maximum heat stress an athlete can safely resist, the sweat rate of that person and their core temperature,” said Dr Carolyn Broderick, Tennis Australia’s chief medical officer.
“The scale also accounts for the physiological variances between adults, wheelchair and junior athletes while also taking in to account the 4 climate factors – air temperature, radiant heat and also the intensity of the sun, humidity and windspeed – that influence a person’s ability to disperse heat from their body”
