"Later in the session, Williamson completed what is known as a box jump, in which he jumped down from an 18-inch box before quickly leaping as high as possible. When he did, those force plates recorded that he had created 4,900 newtons worth of force — about twice the amount needed to crack a brick with a karate punch. It was also the highest such figure the P3 officials had ever seen.

Says Dr. Marcus Elliott, founder of P3: "Zion has the highest peak force of any athlete we've ever assessed — and he was still in high school."
