What Role Does Science Play in the World Cup?
Jul 10 2018 Read 1118 Times
For most football fans, watching the 2018 World Cup calls for HD televisions and plenty of beer. Unless of course, you're one of the scientists hired to meticulously follow and analyse every move of the players and the ball. Representing a host of disciplines, many sports scientists will be analysing all facets of the beautiful game, including ball aerodynamics, player psychology and the human physique.
Want to know more? Here's a glimpse at the science behind a FIFA match.
Since 1970, Adidas has designed the balls used in the FIFA tournament. While years of research was channelled into developing 2018's offering, the Telstar 18 has received heavy criticism from some goalkeepers who claim it's erratic and hard to grip.
Not everyone agrees, with some experts maintaining that it offers goalies a significant advantage over previous World Cup balls. Compared to the Brazuca, the predecessor ball used for the Brazil 2014 tournament, the Telstar 18 creates more drag as it flies though the air which means it covers eight to 10% less distance when kicked at speeds of over 90 kilometres per hour.
"That could be bad for strikers who kick from a great distance and must therefore kick the ball very hard," explains Eric Goff, a physics professor at Virginia's University of Lynchburg.
According to some sports psychologists donning red can be a genuine advantage. Research from England's University of Chichester suggests that players wearing red jerseys are seen as more skilled and dominant by their opponents and enjoy an internal self-confidence boost.
"An alternative explanation is that we have simply learnt from a very young age that red is associated with danger (warning signs are red) and failure (teachers may mark with a red pen)," comments British sports psychologist Iain Greenlees.
Creativity on the field
Other experts maintain that tactical creativity is the key to success, as demonstrated by dynamic players like Messi, Ronaldo and Neymar. All have the scope, skills and flamboyance to pull of surprise moves in high-pressure situations, thus firing up fans and taking opponents by surprise. A recent study published in the Journal of Sports Sciences confirms this theory, concluding that "high creativity" is a solid predictor for victory.
Spectrochemistry can also play an important role in the sports science sphere, with recent findings warning that "heading" footballs can cause brain injury.
