Abstract:
Background:Elite athletes regularly participate in national and international sporting competitions while simultaneously engaging in high-intensity and intensified training programs. Therefore, assessing changes in blood biochemical parameters is of considerable importance for evaluating athletes’ physiological adaptation to training loads. In particular, determining the activity of lactate dehydrogenase enzyme in athletes’ blood plasma provides a scientific basis for improving individual performance, evaluating sports performance, and enhancing the effectiveness of future training programs.
Aim:To examine plasma lactate dehydrogenase enzyme activity in athletes of the Mongolian National Team.
Materials and Methods:A total of 51 athletes, including 26 men and 25 women from 6 types of sports of the Mongolian National Team included in the study. Anaerobic capacity was assessed using a Monark 894E Ergomedic Peak Bike, designed to apply exercise load. Blood serum lactate level and lactate dehydrogenase enzyme activity were determined using a Biobase BK-280 fully automated biochemical analyzer. Heart rate, peripheral blood oxygen levels, and oxygen saturation were measured using a pulse oximeter.
Result:The average age of the participating was 24.04±4.15 years, with average height of 168±8.78 cm and average weight of 71.01±7.69 kg. The average BMI was 24.82±4.12 kg/m². Pre-exercise lactate dehydrogenase enzyme activity averaged 177.1±28.96 U/L, while post-exercise lactate dehydrogenase activity averaged 223.5±51.56 U/L. The average heart rate before exercise was 66.04±8.9 bpm, while post-exercise heart rate was 123.6±16.06 bpm. The average VO2 max was 95.18±2.48.
Conclusion:The activity of the enzyme lactate dehydrogenase before and after exercise showed significant differences in the age groups 20-29 (p<0.01). When comparing lactate dehydrogenase enzyme activity before and after exercise by sport, statistically significant increases were observed in freestyle wrestling and judo athletes (p<0.01).
