Evaluating the Size of the Effect of the Quantitative Contribution of Some Biochemical Variables to the Jump Shooting of Back Line Players in Handball

Abstract

His study included the problems that the researchers were trying to answer, namely: Is there a relationship between biochemical variables (LDH, catalase, lactic acid, cortisol) and jump shooting for young players? In order to broadly understand the impact of these variables on performance tolerance in order to benefit from their influence. The most important objectives of the research were to identify the relationship and contribution rates of biochemical variables (LDH, catalase, lactic acid, cortisol) to jump shooting.

The researchers chose the descriptive approach using the survey method and correlational relationships, for its suitability and the nature of the research. The research sample was representative of the research community itself. For the purpose of ensuring the efficiency of the equipment’s work and ensuring the integrity of the procedures for the experiment and the efficiency of the auxiliary work team, the researchers conducted the exploratory experiment with 10 players from the research community. After ensuring the integrity of the procedures in the exploratory experiment and the results that he benefited from, there was nothing left for the researcher but to carry out the main experiment.

The most important conclusions: There is a strong correlation between cardiac energy and the investigated biochemical variables (lactic dehydrogenase, catalase, lactic acid, and cortisol) and jump shooting. The most important recommendations were to study the physical and physiological aspects in addition to the motor, physical, mental and skill capabilities in order to determine the performance levels of players, especially in the youth category.
