Opis:: Complex methodology was applied to study a movement structure in the standing back tuck somersault (SBTS). We have checked the usefulness of the multi-modular measuring system (SMART-E, BTS, Company, Italy) consisting of six infrared cameras, and the wireless module Pocket EMG, for measuring muscle bioelectric activity and force plate (AMTI, USA). Software Smart Analyser was used to create a database allowing the chosen parameters to be compared. Using a comprehensive methodology in the studies of the back somersault, performed with the landing at the same place (salto – S), allows for the presentation of the external and internal structure of the movement of this exercise.

Opis:: The purpose of the study was to determine velocity changes in relation to the load lifted along with their muscular activity. Twenty athletes representing different sport disciplines, familiar with the flat bench press took part in the research project. The ANOVA analysis revealed a significantly higher effect on range of mean velocity (F = 128.34; η2 = 1.22 with p = 0.001) and maximal velocity (F = 7 3.31; η 2 = 0 .81 w ith p = 0 .001) t o m easured l oads ( 70÷100% 1-RM) i n a scending p hase. Tukey’s p ost-hoc t ests revealed a statistically significant difference between 70% and 100% 1-RM loads, in mean velocity with p = 0.001 and maximal velocity with p = 0.001. Similarly the results revealed a statistically significant difference between 80% and 100% 1-RM loads in mean velocity (p = 0,012) and maximal velocity (p = 0,021) during the ascending phase. Relationship between velocity and the muscles activity indicates that the anterior deltoid and latissimus dorsi muscles show synergy and a significant relationship for loads 90 and 100% 1-RM. The triceps brachii muscle shows a higher relationship with velocity of the barbell for loads 70% and 80%, then the relationship of the pectoralis major muscle with velocity only for 90% 1-RM.
