  The present study investigated the circadian rhythm variations of heart rate and blood pressure due to 1 (60 minutes) and 2 split exercise sessions (2 × 30 minutes) a day. Fourteen healthy students from the University of Tabriz volunteered to participate in current study. Two groups of subjects in a crossover design were randomly allocated as group I (one session per day, twice a day) and vice versa for group II. Having completed the test (treadmill running with an intensity of 70 per cent of Maximum Heart rate), heart rate and blood pressure (both systolic and diastolic) were measured every two hours for 24 hours. Repeated measure (ANOVA) was used for analysis. Each of variables showed normal circadian rhythm. Compared to two split exercise sessions a day, one session a day demonstrated that the level of heart rate circadian rhythm has been set at a rate of five percent below. C.. Read More»
