Inside the Tesla lab where workers train the Optimus robot by doing the Chicken Dance, sprinting, and wiping tables - Business Insider

World Athletics goes inside the numbers behind the disciplines on the Ultimate Championship programme. Guiding us from the starting gun to the finish line in the 100m are Edrick Floreal, coach of Olympic champion Julien Alfred, and former world sprint medallist Craig Pickering, now Director of Performance Sustainability at Australian Athletics. Pickering sees the 100m as akin to a maths problem which needs the perfect equation to solve it. “The person who wins has the highest average velocity,” he explains. “It’s not the person with the best top speed or best acceleration.” Despite his years of coaching experience, Floreal still describes the event as “complicated” and relishes the challenge of unpicking it. For him, it is less a maths equation and more a fast-paced jigsaw puzzle: “There’s elements of the 60m dash in it, elements of the 200m and elements of the 400m. I like the 100m because of the numerous factors that play a part in being good at it. You can’t just get out of the blocks and race as hard as you can.”

Just three minutes of sprinting may produce a molecular response that looks very different from what happens after 90 minutes of moderate exercise. Researchers at Rockefeller University compared how the body responds to exercise performed at different intensities. They found that six 30-second, all-out sprints changed nearly one-quarter of the proteins measured in the blood immediately after exercise. By comparison, 90 minutes of continuous moderate cycling altered less than one-quarter of one percent. Moderate treadmill running affected more proteins than cycling, but still far fewer than the brief sprint session.
