Thanks, Stuart. I think Ege’s point is that there is less variation in activities that humans have done for a long time, which does not apply to all sporty activities. I would say most of olympic gymnastics and professional basketball do not qualify, whereas walking and running do. The fastest marathon was run in around 2 h, whereas a random person with age 30 can maybe complete one in around 9 h moving at a walking pace of 4.67 km/h[1] (= 42⁄9), which is 4.5 (= 9⁄5) times as much time. In contrast, a random person would not beat the best chess players even if they had 4.5 times as much time (unless they had very little time like 4.5 s against 1 s for the top players).

Healthy young people can walk all day if needed even if they do not exercise regularly.
