ANALYSIS AND RESEARCH ON FITNESS BIOMARKERS IN VOLLEYBALL ATHLETES DURING COMPETITION

Abstract

ABSTRACT Introduction: Athletes’ physical conditioning is closely related to the type of sport dedicated, training levels, intrinsic conditions of the athletes, type of load, and recovery status after exercise training. There is ample documentation on the physical conditioning of volleyball athletes in normal situations, but the literature is lacking in surveys during competition periods. Objective: To explore the physical conditioning through analysis of body biomarkers in volleyball athletes in competition. Methods: Before and after the summer training, fasting urine and blood samples were collected from five female volleyball players. Biomarkers involving white blood cells, red blood cells, hemoglobin, etc., were detected, recorded, and the data were statistically analyzed. After the general analysis of the sample, a case study of two elite female athletes was conducted. Results: The urea nitrogen value of athlete A decreased from 7.62mmol/L to 4.91mmol/L, and the urea nitrogen value of athlete B decreased from 6.91mmol/L to 6.57mmol/L; the urea nitrogen values of both athletes showed a downward trend. Athlete A’s physical function status decreased significantly after summer training, while Athlete B’s physical function status improved slightly. Conclusion: During the summer training period, it is necessary to perform continuous index measurements on the athletes to increase the timeliness of the data, which is conducive to in-depth analysis of the athletes’ fitness status.
