44) The major factors in accurate throwing include: a. upright posture, opposed big toe, large saddle joint on greater multangular. b. Glenoid fossa laterally directed, mental ability, crisis c. Glenoid fossa directed upward, forward facing eyes, analogous thinking d. Glenoid fossa directed downward, large brain, forward facing eyes. e. None of the above

Answer 1

The accuracy of throwing in games and sports is governed by how errors in planning and initial conditions are propagated by the dynamics of the projectile. In the simplest setting, the projectile path is typically described by a deterministic parabolic trajectory which has the potential to amplify noisy launch conditions. By analysing how parabolic trajectories propagate errors, we show how to devise optimal strategies for a throwing task demanding accuracy. Our calculations explain observed speed–accuracy trade-offs, preferred throwing style of overarm versus underarm, and strategies for games such as dart throwing, despite having left out most biological complexities. As our criteria for optimal performance depend on the target location, shape and the level of uncertainty in planning, they also naturally suggest an iterative scheme to learn throwing strategies by trial and error.
