CARDIOVASCULAR MONITORING IN THE TRAINING OF LONG-DISTANCE RUNNERS

Introduction: Strengthening research on cardiac function risk assessment in running sports is beneficial to prevent sport-related cardiovascular injuries and sudden deaths in sports. Objective: To study changes in cardiovascular response in athletes after long-distance running. Methods: Changes in cardiovascular response indicators of long-distance runners before and after the five-kilometer race were monitored. Analyzed indices included heart rate, blood pressure, hemoglobin, and a cardiac function index. Results:There were no statistically significant differences in heart rate, blood pressure, and hemoglobin levels before and after the long-distance run (P>0.05). There was no significant difference in the proportion of sinus arrhythmia before and after long-distance running (P>0.05). Conclusion: Long-distance running did not cause abnormal changes in blood indicators. No cardiovascular discomfort or changes in the electrocardiogram, heart rate, blood pressure, hemoglobin, and cardiac function index were reported.These young men were not enlisted, despite undergoing adaptive training. In conclusion, the five-kilometer run is safe for young men in the reserve.
