The strongest evidence to support the argument in favor of making video gaming an official sport would be:
A study conducted by a leading university showed that during gameplay, a gamer's heart rate can rise to the same beats per minute as a runner during a marathon.
This evidence directly relates to the physiological demands of gaming and draws a parallel between video gaming and traditional sports, highlighting the athletic nature of competitive gaming. It provides a concrete metric that suggests gaming can involve intense physical exertion similar to recognized sports.
