Optimal rhythm zone for competitive weightlifting

BACKGROUND: Success in weightlifting is determined by the execution of two lifts, the clean and jerk and the snatch. However, an effective lift may be affected by various factors, from body type differences to the cross-effect of lifts. The latter is an urgent issue in competitive weightlifting research. AIM: This study aimed to assess the effectiveness of the developed uniform tools and methods for assessing the biomechanics of lifts in weightlifting competitions to determine the optimal rhythm and tempo zone, analyze the cross-effect of lifts, and improve the technique of weightlifters for competitions. METHODS: The experiment involved the two rated athletes (athlete A, First Class, and athlete B, a Candidate Master of Sports, competing in the same weight class of up to 81 kg) and 22 weightlifters of various classes, ages, genders, and weight. We analysed scientific and instructional publications and conducted tests, pedagogical observations, a pedagogical experiment, and a correlation analysis. RESULTS: The study showed the need to consider the cross-effect zone of competitive lifts in weightlifting when preparing for competitions. Experiments prove that there is an optimal rhythm zone, i.e. a zone of equipment (barbell) weights with the least cross-effect of competitive lifts and no effect on the lift structure. As a result, competitive reliability increases. CONCLUSION: The proposed tools and methods for assessing the biomechanics of lifts in weightlifting competitions allow for the most effective combination of both special (auxiliary) and basic training for competitions and the effective use of the order of exercises and their intensity in planning training sessions and promptly assessing the physical fitness of athletes and their technique.
