RELATIONS OF BIOCHEMICAL PARAMETERS IN THE ENDURANCE AND PHYSICAL FITNESS OF SOCCER PLAYERS

ABSTRACT Introduction: Many factors restrict the development of soccer technology. An athlete’s body constitution, quality, and physical function are essential for achieving technical development. Objective: Analyze the relationship between biochemical parameters on sports endurance and the physical fitness of soccer players. Methods: Samples were collected from volunteer players 20 days before the game, during the adjustment period, and on the morning of the intensive game. Enzyme staining and immunofluorescence method were used for hemoglobin detection. Results: Male soccer players had an average Hb of 15.18 g/dl in pregame preparations and dropped to 13.97 g/dl in high-level games. These data were statistically significant (P<0.01). Conclusion: Cortisol in high-level soccer players rapidly produces several stressful substances in the body. The blood sugar content of participants from elite youth soccer teams in China is within the normal range. The research findings of this paper can provide a theoretical basis for the formulation of soccer training strategies. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
