Is eSports real sports? It’s a debate that will not die any time soon.

And one university is set to add more fuel to the already heated debated of whether professional gamers should be considered as athletes.

German broadcaster Deutsche Welle reported that a new study conducted by researchers at the German Sports University found that many eSports players are not fit to face the physical demands of playing in professional tournaments.

GSU Professor Ingo Frobose, who have been studying eSports players for the past five years, discovered professional video game players are exposed to a level of strain that was not present in other sports, even among table tennis players, who require a high level of hand-eye coordination. The professor observed that eSports players’ hands fly on the keyboard or mouse at a maximum of 400 movements per minute which is four times higher than an average computer user.
