摘要
The invention relates to sports training devices and can be used for training a volleyball spike-motion. The inventive device comprises a bearing frame, a ball, and a unit for returning the ball to the initial position thereof, which unit is provided with an elastic stretching connected to the frame by one end thereof, a rod whose one end is fixed to the frame in such a way that it has at least two degrees of freedom, whereas the second end of the rod is connected to the ball, and the second end of the stretching is connected to the rod. The frame is also provided with a limiter of traveling the rod. The device enables the ball to be moved along an arc, thereby increasing the quality of the spike-motion training, and improves effectiveness and safety of the training.
