Comparison of the Effect of Endurance and Speed Training Session on Plasma ANP in Male Athletic Students in Yazd

The ANP is a cardiac neutrodiortic peptide which is secreted from the granules in atrial muscle cells during atrial expansion which helps balance the body's fluids by affecting the kidney. Studies have linked this hormone to cardiovascular disease. This study aimed to compare the effect of one session of endurance and speed training on the ANP in male athlete men. For this purpose, 90 male athletes were randomly selected and divided into three groups of endurance, speed, and control. Third, the heart rate was reduced, and they ran. Blood samples were taken 10 minutes before and 10 minutes after the exercise to measure plasma ANP. The results showed that one session of endurance and speed activity significantly increased the plasma ANP levels compared to the pre-test (p < 0.05). There was training (p < 0.05). However, the difference between the endurance and speed groups was not significant (p < 0.05). Consequently, it can be stated that a session of endurance and speed activity increases the plasma ANP of athletic students, and there is no difference between the effect of endurance and speed on ANP increase.
