| Abstract | ||
| The objective of this research was to identify the impact of pre-competition in some electrical activity (EMG) variables of deltoid muscle in serving skill of sitting volleyball, and the research hypotheses that there are significant differences between pre-competition and subsequent changes of electrical activity (EMG) of deltoid muscle in the skill of sitting volleyball serve. The sample included 8 players of the Iraqi national volleyball setting team, who were disabled, experiment was carried out in the interior hall of the Physical Education for girls - University of Baghdad, from 1 25 2010 to 2 27 2010, and the variables of the study: Electric peak, root mean square (RMS), and area of muscle activity in serving skill. The researcher concluded the following conclusions: A significant effect of pre-competition in the electrical activity variables (Electric peak, root mean square (RMS), and area of muscle activity) of deltoid muscle in the skill of the serving. And recommendations: - Involve other muscles of the arm conscious volleyball sitting for ID characteristics of each player and the establishing training schedule to improve the muscles, and paying attention to their studies, especially studies of EMG to improve their completion. | ||
