Effectiveness of the Involvement Of Selected Muscles During the Pre-Jump and Wind-Up Phase During the Execution of a Spike In U16 ? U18 Female Beach Volleyball Players

Original language description

Background: Laterality in beach volleyball is ma inly ma nifested in the a ttacking activities of a n individual (serving, spiking). Functional asymmetry a ffects the player&apos;s movement ex-pression in all movement situa tions, a nd la terality is also importa nt for the specializa tion of individual players.Objective: The study a ims to assess the la teral involvement of selected muscles (deltoideus, biceps femoris semitendinosus) a nd their efficiency in the phases before the spike jump a nd in the wind-up phase of the spike.Materials and Methods: The resea rch group consisted of 12 female players with a n average age 16.17 (SD= 1.5). The ma in method used for da ta collection was measurement by Norax-on surface electromyography. We entered the tra nsformed da ta into Microsoft Excel 365 for Mac. To evalua te the da ta, we used descriptive (frequency, percentage) a nd inferential (Shapiro-Wilk test, T-test, Ma n Whitney U test a nd correla tion) sta tistical methods. Results: The conclusion of the study is tha t there is no difference between the right a nd left sides in the evalua ted muscle groups (deltoideus= 0.206; biceps femoris=0.569; semitendi-nosus=0.792). An interesting finding of the study is the strong correla tion between the left deltoideus a nd the right biceps is interesting (0.812). The efficiency is higher in the wind-up phase of all the assessed muscles. The highest difference in efficiency is in the biceps femoris on the left leg, where the difference in efficiency of engagement in individual phases is over 25%. Conversely, the lowest difference is for the left semitendinosus (5.5%).Conclusions: The study confirms tha t the effectiveness of muscle activity is more efficient in the wind-up phase, a t the sa me time we add tha t in this phase the muscles work more symmetrically.
