Realization of Speed-strength Manifestations at Improvement of Metabolism of Energy of Muscle Contraction

The aim of the study is to: improve the speed-strength qualities of freestyle wrestlers and judokas; develop their endurance in anaerobic exercises; and increase lactate utilization during speed-strength exercises and during the recovery period during the improvement stage of athletic skill. Methods and organization of the study. Analysis and synthesis of scientific and methodological literary sources. Pedagogical observations, an experimental study, and physiological and biochemical (lactic acid (lactate) concentration levels in capillary blood) methods were used. A comparison of the effectiveness of speed-strength exercises, including wrestling techniques, and blood lactate levels during the recovery period. Freestyle wrestlers and judokas in the experimental group performed aerobic exercises during the recovery process with movement coordination similar to the exercise being trained. Wrestlers in the control group used passive rest to recover from anaerobic exercise. Study results and conclusions. As a result of performing control anaerobic exercises at the end of the experimental training session, subjects who used active rest for recovery demonstrated a significant positive improvement in their results. Moreover, blood lactate levels remained virtually unchanged during the first minutes, but starting from the third minute, lactate utilization significantly (p<0.05) improved compared to baseline. At the end of the experiment, wrestlers who used passive rest demonstrated significantly (p<0.05) lower performance in control exercises than wrestlers who used active rest, while their blood lactate levels increased significantly (p<0.05) compared to baseline.
