دراسة مقارنة لبعض المؤشرات الكيميائية والوظيفية لأنظمة الطاقة الغالبة لمهارتي الارسال القاطع و الساحق في التنس الارضي

Abstract EN

The aim of the research is to identify the differences in some components of the blood between the two energy systems (oxygen and non-oxygen) for the skills of categorical and overwhelming transmission, and on the differences in some functional components of the heart between the two energy systems (oxygen and non-oxygen) for the skills of categorical and non-oxygenic transmission.

The researcher used the descriptive approach in the style of survey studies.

To suit the nature of the research problem, the research sample was intentional and consisted of (20) players from Baghdad tennis clubs for the year (2020-2021) and divided into two groups according to energy production systems, the first group (10) players with the oxygen energy production system and the second group ( 10) players with anoxic energy production system, and the researcher concluded that there are significant differences in the ratios of red and white blood cells between the two energy production systems (oxygenic and non-oxygenic) and in favor of the oxygenic system, with significant differences in the number of heartbeats for the two research groups between the two energy systems (oxygenic) and anoxic), and he recommended paying attention to oxygenic activities and skills to increase the number of red and white blood cells and the volume of the left heart ventricle, with studies on the activities of other ri.
