Will the Olympic Games without fans affect the normal performance of athletes?

Without the audience, fans will not affect the normal performance of athletes in the Tokyo Olympic Games, and some will even play better. Because after years of training and exercise, athletes will produce their best results in the competition, and their normal performance will not be affected by fans. Normal play should not have much impact, but the atmosphere is gone at once. For example, the cheers of the audience in football and basketball games can stimulate the motivation of athletes, but it doesn't really matter whether there are spectators or not for games that need a quiet environment, such as air guns. Some athletes may play better in a quiet environment.
