Abstract des Autors

Training process can be controlled effectively, especially with elite athletes in case of constantly available actual information on their state, comparing it with training loads and, if necessary, correction of training plan. Three types of control are defined in sport: on-line, current and phased. In sports biomechanics, mainly studying technique of sports exercises and athlete's motor capacities, these types of control have its peculiarities. On-line control is aimed at estimation of the quality of performance of sport exercise after a motor task. Current control provides information of the athlete's state in weekly training cycles. Phased control is to estimate athlete's fitness level after long-term training. The purpose of the present research was to work the method of on-line and current biomechanical control of technical and speed-power fitness of weightlifters, satisfying the requirements stipulated above. The worked method of instrumental biomechanical monitoring can be used not only within the training process but also in official competitions. But nowadays it is possible only based on the weightlifting hall of Russian state university of physical culture, sport, youth and tourism, where a force platform is arranged. The advantage of this method compared to the existing ones consists in the capacity of immediate (within 2 minutes) receipt of information on movement of general center of mass of the "weightlifter-bar" system and motor dynamic indices.
