The strongest support for the argument in favor of making video gaming an official sport would come from:
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 is compelling because it directly correlates the physical exertion experienced during gaming with that of traditional sports, providing a quantifiable measure of the physical engagement that can occur during gameplay. It emphasizes the physiological aspects that are integral to defining a sport, making a stronger case than the other options presented.
