Aim. This research was undertaken to measure the heart rate (HR) response performing indoor cycling session, and to determine the validity of Borg scale of Rating of Perceived Exertion (RPE) as a measure of exercise intensity in subjects who have had a 6-month experience in the indoor cycling activity.
Methods. Eighty healthy subjects, including 19 males and 61 females (mean age: 32.3±9.5 years), were recruited from a private fitness club. The indoor cycling session consisted of a warm-up, cardiovascular phase and a cool down and, finally, stretching exercises off of the bikes, with a total duration of 45 minutes.
Results. The mean HR in the cardiovascular phase was 144.11±13.8 bpm. The mean values of the percentage of heart rate reserve (% HRR) and overall RPE in the cardiovascular phase were 77.8±7.2% and 14.3±1.7 points, respectively. The correlation value between overall RPE and %HRR, was r=0.18 (P>0.05).
Conclusion. The reduced validity obtained for the overall RPE and the high intensity reached in adults during indoor cycling session suggest a more importance of controlling the intensity of this activity for adult subjects.
