Objective of the study was to theoretically substantiate and analyze practical benefits of a new training model for the weightlifting elite. Methods and structure of the study. We analyzed for the purposes of the study the relevant study reports on the modern training technologies and human body adaptability issues in extreme weightlifting training cycles. We gave a special priority to the specific cellular-level adaptation mechanisms in our study. The study included findings of a long-term new training model testing experiment. The model was designed with account the theoretical and practical research findings analyzed herein. Results and conclusions. In the experimental training model design, the most important task was to ensure selective hypertrophy of the fast muscle fibers in those muscle groups that determine the working effect of the competitive exercises. We also considered the mechanisms of reaction of the endocrine system to stress loads and the targeted assimilation of hormones into the "target cells" - in this case, into the fast muscle fibers. The study made it possible to systematize the factors that promote the synthesis of nucleic acids and proteins in the muscle fibers, on which the intensity of myofibril mass accumulation depends, and which, in turn, affects the strength of muscle contraction. We also studied the factors that suppress the effects of intracellular synthesis of structural proteins and reduce the intensity of accumulation of myofibril mass. The new weightlifting training model piloting experiment showed the model being beneficial as verified by the competitive progress of the Kazakhstan Republican weightlifting elite that won since then quite a few medals at the Asian Weightlifting Championships, Asian Games, World Championships and Olympic Games.
