N2 - The purpose of this investigation was to compare the Counting Talk Test (CTT) method to the Heart Rate Reserve (HRR) method for estimating exercise intensity. Thirty-four healthy individuals (21 F and 13 M) aged 20-31 years old participated in two separate treadmill trials. During the first trial subjects walked/jogged on a treadmill at 50%, 60%, 75% and 85% of their HRR. Blood pressure (BP), heart rate (HR), CTT score and rating of perceived exertion (RPE) were obtained at each workload. During the second trial subjects again walked/jogged on the treadmill at four different intensities based on the CTT values obtained during the first trial. BP, HR, and RPE were recorded. Two-way repeated measures ANOVA were used to compare variables. Moderate Pearson correlations (r) were found between the CTT and HRR, RPE and MET level, and that exercising at 30%-55% of the resting CTT value corresponded to the American College of Sports Medicine recommendations for moderate to vigorous exercise intensity. Strong correlations were found between the two treadmill trials for; 1) %HRR (r= 0.90), 2) RPE (r= 0.83), and 3) MET levels (r= 0.88). Comparing the CTT method to the HRR method, the CTT appears to be a reasonable means of estimating exercise intensity.
