The evidence that would give the strongest support for the argument in favor of making video gaming an official sport is:
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 relates to the physical exertion and competitive nature often associated with traditional sports. By demonstrating that video gaming can elicit a physical response similar to that of conventional sports, it supports the idea that video gaming meets criteria commonly applied to sports, such as physical intensity and competition.
