Background: Our body is under the influence of a 24-hour period which regulates body temperature, blood pressure, metabolism, hormone secretion and their functions. Thus, it is probable that while doing exercise or following that the function of the body varies in different parts of the day. The goal of the present study was to assess the effect of the time of exercise (morning or evening) on the amount of Troponin T in men with cardiovascular diseases.

Methods: To carry out this semi-experimental study, 15 men with cardiovascular diseases were selected as the participants of the research. On the day of the test, the participants gave a blood test at 7 o’clock in the morning and then carried the exercise protocol out in presence of a physician. Then, the participants gave blood tests immediately after exercising and 3 hours after that. A week later the participants took the same steps with the same method but at 7 o’clock in the evening. Through SPSS v.20, the data were analyzed using dependent T test for comparing average of pretest and posttest of anytime (morning and evening) and comparing both tests in both morning and evening.

Results: The results of the present study revealed that there was no significant difference in the amount of Troponin T in the morning and evening before (p= 0.15), immediately after and 3 hours after the same maximum exhaustive exercise (p= 0.22, p= 0.30).

Conclusion: Based on the findings of the present study, the circadian rhythm and day-and-night cycle are not affected by intense exercise in response to the myocardial tissue. Consequently, patients with cardiovascular diseases can exercise either in the morning or in the evening as they wish.
