A practice apparatus for a swing type athletic equipment capable of permitting a practicer to accurately know a locus of a ball hit. A triaxial acceleration sensor is mounted in a head of a golf club. Acceleration data in three detection-axis directions outputted from the triaxial acceleration sensor are transmitted to a data processing unit through a data transmission unit arranged in the grip. The data processing unit analyzes a locus of a golf ball hit and swing thereof based on the acceleration data. Results of the analysis are displayed on a monitor.
