Abstract: A system for analyzing starts and acceleration phases in squat-style track and field events has: a launching stand, a plurality of wireless cameras, a technical analysis host, two foot tracking devices and a gyro group. The launching stand has at least one acceleration sensor and an adjusting support connected to two pedals. The technical analysis host is connected to the acceleration sensor and the wireless cameras, the acceleration sensor actives the wireless cameras to collect instantaneous speed data of a runner, and the technical analysis host generates a 100 m speed curve L1 of the runner, and the 100 m speed curve L1 includes a continuous reduced acceleration section L2. The two foot tracking devices are installed on two feet of each runner. The gyro group have a first gyro, a second gyro, a third gyro and a fourth gyro.
