It is thought that measuring electrical activities in muscles during sportive performances and analyzing them with
appropriate methods is one of the new approaches. Serving in volleyball is an effective offense technique. If it is
done with the perfect speed, distance and the technique, it can cause opposing team to lose the point directly. In
this regards, we aimed to study the effects of short and long serves associating them to muscle activation. 12 female
volleyball players from minor league of Turkey Volleyball Association participated in this study. Their average of
age was 20,4±1,6. Their muscles activations of M. Deltoideus, M. Deltoideus Anterior, M. Biceps Brachii, M.
Triceps Brachii, Wrist Extensor Group, Wrist Flexor Group which were in shoulders and arms were checked
during short and long serve. The silver/silver chloride (Ag/AgCl) bipolar superficial electromyography electrodes
(Blue sensor P-00-S Ambu, Denmark) were located in the center of the muscles in parallel with muscle fibrils.
Distance between electrodes was 20 mm. They were located in body-muscle points according to Clinical SEMG
Electrode Sites. Before location of electrodes, the skin was sterilized with alcoholic solution to block the artifacts
and it was shaved to make it smooth. The cable was immobilized so that the hit of electrodes could not cause
something adverse. ME 6000 (Mega Electronics Ltd. Finland) portable EMG device was used in muscle activation
measurement. Data sample speed was 1000 Hz. Device was fastened in subject’s waist with a belt. Data were
checked by considering their descriptive statistics in SPSS software, and they were analyzed with Wilcoxon test.
Significant differences in P<0,05 level were found. It was finally found that M.Triceps Brachii muscle worked
more effectively in long serve while M. Deltoideus Anterior muscle worked more effectively in short serve. In
this regard, creating training and technical abilities may give us better results.
