This experimental study aimed to examine the effect of fasting throughout the month of Ramadan month on Heart Rate (HR) during endurance exercise and Heart Rate Recovery (HRR) after exercise. 27 participants were included in the study. The participants were separated into two groups as the experimental group fasting before the experimental study(F; n: 13; 20,22 ± 1,58 years; 179,84 ± 5,99 cm, body weight 7169 ± 8,48 kg; BMI 22,12 ± 1,91) and the non-fasting control group (NF; n:14; 19,64 ± 1,15 years; 182,42 ± 3,79 cm, body weight 72,20 ± 4,75 kg; BMI 21,64 ± 1,50). In the experimental study, the HR ( during the endurance exercise of 5,000 m and HRR ( values after the exercise of the F and NF groups were recorded by using a heart rate monitor (Polar V800, Lake Success, NY, USA),which records once per second. Descriptive statistics and an independent sample t-test were used in the statistical analysis. During the endurance exercise, there was no significant difference in terms of HR between the participants of F and NF (p>0,05). By the end of the endurance exercise, there was a significant difference over the HRR in the 1st minute (p=0.018; t=2,505 p<0,05) and in the 2nd minute (p=0.031; t=2.270 p<0,05) within F. There was no difference between these two groups in terms of HRR in the 3rd, 4th and 5th minutes. While fasting has no positive or negative effects on HR during endurance exercises, it has a restrictive effect in the first minutes of HRR after exercise.
