If you take an average player, it might cover 10km.
that might drop off by around about 10%.
The approach to the game might change substantially as well.
Although there's some cognitive and decision-making declines that come with heat stress, we know that actually an interesting proxy to that pass accuracy tends to go up when the conditions are hot.
And that reflects players making more conservative passing decisions to retain possession and avoid the need to do lots of high-speed running to recover the ball.
There is a chance, I think the spectator might observe, that the games feel a little bit less thrilling, for want of a better word.
To spend longer periods than FIFA have currently mandated, they have a three-minute cooling break, which potentially is insufficient, and a six-minute break would allow for more meaningful rehydration and cooling.
potentially there is a scenario that we haven't really seen in football in the same way we might have seen it in endurance sports like marathon running, for example, where we receive pictures of a player collapsing in the game and there's a suspension of play.
Perhaps the temperature and the heat stress conditions mean that games are postponed and or delayed in game for substantial periods of time.
All of those are really concerning scenarios.
focused our letter and the research on a metric called wet bulb globe temperature, which encapsulates all of the environmental conditions that the players will experience.
So it takes into account the air temperature of the environment that the players are playing in.
But it also acknowledges that heat stress goes beyond just temperature.
So there's a need to acknowledge the impact of humidity on the players, the impact of solar radiation.
So effectively feeling the sun on your skin and the heat stress that that imparts.
as well as the potentially helpful cooling effect that comes from airflow and the wind speed that affects players.
In that scenario, the body temperatures increase quite substantially, one, maybe two or even three degrees Celsius above its resting levels.
The body also has what we call a reflex response to increase body temperature.
So we'll see redistribution of cardiac output or the blood flow away from what the body deems to be non-essential organs in that moment.
So, for example, the gut, the gastrointestinal tract, the kidneys and the liver, that's not without complications in its own right.
