Real-Time Data for Going Big in the Half-pipe

摘要

Don't let the headphones and baggy pants fool you. Snowboarders are intensely competitive. Last fall, members of the U.S. team began recording their velocity, body angle, and G-force with a wearable device to gain an advantage. The Catapult Sports Minimax S4 contains an accelerometer, gyroscope, and magnetometer; during training runs in the half-pipe, it takes readings every tenth of a second. Athletes can then match the data to video footage to pinpoint areas for improvement.
