Abstract

Salto forward tucked is one of the most spectacular elements of acrobatics. During her performance, gymnast manifests her technical skills by coordinating every movement of her body parts with maximum precision. With the system for kinematic analysis - APAS (Ariel Performance Analysis System), was analyzed the performance of salto forward tucked by a quality gymnast. The results of the body position and the trajectory of her movement show greater displacement of the body's gravity center in the anteroposterior direction - forward (208 cm), then in the vertical-high (60 cm) direction, while in the mediolateral direction - the displacement value is symbolic (3 cm), which shows the high precision of performing salto forward tucked. The highest point of the center of gravity of the body from the carpet during the flight phase is 154cm and is reached for 2.16 seconds of the fly-off phase that represents 55% of the flight phase time (3.92 seconds).At the top of the center of gravity trajectory, the angles in the angles are: knees-64 °, thigh-75 °, arms-20 ° and elbows-139 °.These values ??confirm correct performance, while the kinematic analysis of the salto forward tucked gives a very useful insight into the technique of performing, finding errors and improving them during the training process.
