دراسة تحليلية للإيقاع الحيوي حول تسجيل ركلات الجزاء و علاقتها بالدورات الأساسية الإيجابية للاعبي كرة القدم في كأس أمم إفريقيا 2019

Abstract EN

This study aimed to analyze the relationship of basic biorhythm cycles in scoring goals for players who took penalty kicks in the 2019 Africa nations cup.

the study relied on the descriptive analytical method, and the research sample consisted of (14) penalty kicks that were done by (11) players from (9) teams.

the SPSS (25) package was used in the statistical aspect for the purpose of reaching the desired research results.

after analyzing the results, the study record that (8) penalty kicks were recorded out of the total (14) penalty kicks, at a rate of (57%), while the missed kicks amounted to (6) penalty kicks at a rate of (43%) of the total penalty kicks.

the biorhythm cycles also achieved varying percentages in the positive and negative curves of the players executing the recorded and missed penalty kicks, while the rate of the general positive and negative vital cycles was 50% for each.

the recommendations were to rely on the biorhythm program in choosing athletes who enjoy positive vital cycles (physical, psychological and mental) to increase the effectiveness of players in sports performance and the ability to score penalty kicks, especially in decisive and final matches.
