Method of phase control of training load when performing a barbell jerk in isokinetic mode

Relevance. t is known that the effectiveness of various modes of muscle strength development increases significantly when combined with the isokinetic technique of muscular motor activity. This feature lies in the fact that the isokinetic technique is based on motor actions, when skeletal muscles in the process of lifting a barbell overcome extreme resistance of a dynamic and isometric nature, regardless of changes in various articular angles, the ratio of levers or the moments of their rotation. The article deals with the actual problem of using an isokinetic method of performing exercises using a simulator when lifting a barbell in a push, since not all weightlifters are able to independently overcome the negative psychological factor that occurs especially in young weightlifters in competitive conditions, due to "fear of weight", "self-doubt", violation techniques for performing individual phases, etc. Research method. The purpose of the study is to substantiate the method of phase-dosed control of the training load in the process of pushing the barbell with two hands in an isokinetic mode using a specially designed device. Research methods. An isokinetic method of dosing the load using a device for weightlifters was used, which allows lifting a barbell of marginal and sub-marginal weights in the following phases without stopping the motor action in a push: traction, undermining, going into a low saddle by the method of a step, half-squat, pushing the barbell onto straight hands into scissors, fixation and completion of the push. The results of the study. The isokinetic method is most effective when using a special device that allows you to provide metered assistance in achieving high maximum results in competitive weightlifting exercises by reducing the influence o f a negative psychological factor, namely, self-doubt, "fear of weight", violations in the technique of performing individual phases, etc. due to repeated successful performance in training conditions lifting barbells for young athletes of maximum weight.
