FIELD: sports, in particular, training apparatuses for controlling and working out of strikes in boxing and other combat events. ^ SUBSTANCE: exerciser has striking apparatus provided with housing and filler and incorporating pressure sensor connected through analog-to-digital converter of its signal to indicating device. Sensor has at least two inductance coils arranged along common axis in spaced relation with respect to each other, said space being restricted by layers of resilient filler. Alternating electric current is supplied to transmission coil while other receiving coil receives electromagnetic oscillations emitted by transmission coil. Filler may be formed from set of layers and comprises spring layers of various densities. Coils may be arranged coaxially with respect to each other. Sensor may additionally comprise at least one auxiliary compensation coil coaxial with respect to receiving or transmitting coil. According to other version, sensor has additional current-conductive member made as closed contour or plate, and at least two inductance coils spaced apart from additional member. Said additional member may be formed as ring, and plate may be made from aluminum foil laminated in film. ^ EFFECT: increased efficiency of exercising process owing to increased information content and precise investigation of strike delivered by sportsman to exerciser. ^ 13 cl, 2 dwg |
