The relationship of systolic blood pressure with the accuracy of the serve from above (tennis) in volleyball at the ages of 13-14 years

Abstract

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.
