Short and stocky footballers like Lionel Messi will be outnumbered by taller and leaner athletes like Erling Haaland in the future due to global warming, according to a new study in the US. Weak tennis players like Andy Murray will be more successful in warmer sports.
A new study on the link between the performance of professional athletes in the US and climate change has found that men with longer, longer limbs, such as Cristiano Ronaldo and Erling Haaland, run faster when temperatures are warmer.
It has been shown that smaller, stout men like Lionel Messi perform better when it’s cold.
Humans are stocky in colder regions, like polar bears, the new study finds. showed that their performance improved when they were weaker, like grizzly bears, in warmer places. The study looked at 173 athletes who have performed in various fields over the past two decades.
Tall, thin men move about 2.5 percent faster when the temperature is higher than short, stocky men, according to study author Professor Ryan Calsbeek of Dartmouth University in the US.
This is because taller men have a larger surface area, so they can dissipate heat from more skin and produce more sweat to cool down.
However, female athletes were also found to run faster in hot weather if they had longer legs, but the difference was not as great as men. Experts explained the reason for this situation as women produce less sweat than men.
On the other hand, the study found that football players grew taller and slimmer from 1973 to 2014. This shows that the muscle and strength of players like Alan Shearer have been replaced by the slim, petite bodies of players like Harry Kane and Marcus Rashford.
“These results definitely show that a weaker tennis player like Andy Murray can outperform Wimbledon in the warmer US Open, or that a cyclist like Chris Froome can do well if he wants to run marathons in hot countries,” said Calsbeek. said.
On the other hand, the scientists compared the performance of athletes in extremely hot places like Hawaii and South Africa and colder countries like Finland and Canada. Peak temperatures in these countries were reported to range from 18 degrees to 39 degrees.
The study compared the athletes’ recorded heights to their leg and arm lengths, measured digitally from race photos.
