The Relation of Systolic Blood Pressure to Accuracy of High Facing Service (Tennis) in Volleyball Players Aging 13-14 Years


Physiological studies are in sports are regarded of the focal studies for those working in the field of physical education and physical training. Through them, one can identify the effect of corporeal effort on athlete's biological systems during competitions or when practicing physical activities. Problem of the study lies in the lack of accuracy of high facing service. The two researchers think that systolic pressure is of vital relation to this deficiency. They have delineated the descriptive approach of associative relations due to its suitability to the study procedures. The research population is identified to be the (12) players of Diyala General Directorate of Education Volleyball team/ Intermediate Level. The whole population is selected as the sample of the study. Thus, Diyala General Directorate of Education/ Intermediate level (male students) is deliberately selected to be the sample of the study in the intentional approach. After tests processing, it becomes clear that there is a strong relation between the study variables. Therefore, the researchers concluded that there is an inverse relationship between systolic pressure and accuracy, the more pressure is there, the less accuracy achieved and vice versa.
