Effect of implicit theories on judgement of cheating acceptability in physical education: the mediating role of achievement goals.

abstract：:We propose a new method, based on inertial sensors, to automatically measure at high frequency the durations of the main phases of ski jumping (i.e. take-off release, take-off, and early flight). The kinematics of the ski jumping movement were recorded by four inertial sensors, attached to the thigh and shank of junio...
