The strongest evidence to support the argument for 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 provides a direct physiological comparison between video gaming and traditional sports, highlighting the intense physical engagement that can occur during gameplay. It reinforces the idea that video gaming can require similar levels of physical exertion as established sports, making a compelling case for its classification as a sport.
