To strike the nearby vertical wickets, players fare better with a fast underhand toss.Īs for the question of whether to throw overarm or underhand, that depends on such factors as the target’s shape, height and distance, said the researchers.
The faster you are, the less accurate you are, so how can we be both? That’s a question we’re pursuing.”Ĭricket fielding is one of the exceptions to the slow-is-more-accurate rule, the study showed. “You don’t just want to be fast or just accurate, you want to be fast and accurate, and this work tells us that this is particularly challenging. Of course, throwing at near-minimal speed wouldn’t work for most baseball pitchers, let alone our rock- and spear-throwing ancestors, whose hunting abilities were crucial to our evolutionary development, he noted. “We’ve compared these calculations to published data of people throwing into wastebaskets we’ve compared it to a study on dart throwing.” “What we find is that almost the slowest arc is often the most accurate,” he said. It's a trade-off that favors slower throws, said Venkadesan. The opposite is true for slow and curved flight paths, with small errors in the angle of release having little effect. The ball travels in a nearly straight line in fast throws, so errors in the angle at which the ball is released are amplified small errors in controlling speed have no effect. “The ball’s just going to carry out the consequences of what you did.” Mahadevan at Harvard University, an applied mathematician who is a member of the Kavli Institute for Bionano Science & Technology and the Wyss Institute for Biologicall Inspired Engineering. “Once you launch the ball, there’s nothing you can do,” said Venkadesan, who worked on the study with L.
The differences in accuracy between a fast throw and a slow one all happen after the ball is released. But lead author Madhusudhan Venkadesan, assistant professor of mechanical engineering & materials science, said the new study actually found that even if a person is equally good at controlling the release at all speeds, faster throws will still be less accurate. One common theory is that the faster one throws a ball, the more difficult it is to release it at exactly the right time. The researchers also explain why certain throwing strategies work best with certain tasks.

accuracy trade-off with a series of calculations that look strictly at the physics of throwing. The study, published April 26 in Royal Society Open Science, focuses on the origins of the speed vs. Throwing fast and accurately is a uniquely human ability (monkeys also throw things, but they’re really bad at it, say scientists). A Yale researcher’s new study looks at why this is. Whether you’re pitching in a major league baseball game or tossing crumpled paper into the trash, the act of throwing is incredibly complex and usually subject to a trade-off between speed and accuracy. Error propagation in throwing depends on the trajectory of the projectile.
