APPLICATION OF POST-ACTIVATION STIMULATION METHOD FOR HIGHLY QUALIFIED SKI JUMPERS’ STRENGTH TRAINING

The purpose of the research is to evaluate the effect of exercises performed within the framework of the post-activation stimulation method on the manifestation of various forms of strength abilities in highly qualified ski jumpers.

Methods and organization of the research. 6 highly qualified female ski jumpers from the Russian national team (4 Masters of Sports, 1 Master of Sports of International level and 1 Merited Master of Sports) were involved in the pedagogical experiment. The experiment lasted 21 days (competitive period). The influence assessment of three sets of exercises performed within the post-activation stimulation method on the strength abilities manifestation was carried out by the method of control tests (upward jump from the basic stance, upward jump from the inrun position) done on a tensoplatform.
To present the data obtained, we used the descriptive statistics indicators (median values (Me) and dynamics statistics indicators (growth rate Tg, %). The Wilcoxon W-test was applied to check the reliability of the changes occurred.

Research results and their discussion. Exercises performed by the post-activation stimulation method aimed at correcting technique errors do not have a high stimulating effect on the athletes’ neuromuscular apparatus in terms of maximum strength, power and speed compared to the other post-activation stimulation method modifications (PASM).
Exercises performed through the post-activation stimulation method aimed at increasing the muscle contraction power have the maximum stimulating impact on the maximum and starting performance manifestation in the non-specific control test «Upward jump from the basic stance».
Exercises performed by the post-activation stimulation method aimed at improving the biodynamic movements have a stimulating effect on the maximum and starting performance manifestation in the specific control test «Upward jump from the inrun position».

Conclusion. The impact of exercises performed by the post-activation stimulation method on various forms of manifestation of the strength abilities of the highly qualified ski jumpers is determined by their kinematics, the muscle work mode and the external resistance magnitude.
