Abstract

The purpose of this study was to assess the consistency of the Counting Talk Test (CTT) method for estimating exercise intensity across various modes of exercise in healthy young adults. Thirty-six individuals completed the study which required participation in three separate sessions within a two-week time period. During the first session, individuals completed a maximal effort treadmill test from which each individual's heart rate reserve (HRR) was calculated. During the second and third sessions, subjects participated in two modes of exercise at each session for a total of four different modes of exercise. Individuals exercised at 40% HRR, 50% HRR, 60% HRR, 75% HRR and 85% HRR. The heart rate (HR), CTT and rating of perceived exertion (RPE) were recorded at each workload. Based on the individual's resting CTT (CTTrest), the %CTT for each exercise stage was then calculated. Pearson correlations demonstrated moderate to good correlations between the CTT and HRR methods, and the CTT and RPE methods for estimating exercise intensity. This study found for individuals with CTTrest <25, moderate to vigorous intensity exercise as recommended by the American College of Sports Medicine HRR guidelines could be achieved by exercising at a level of 40-50% CTTrest. Individuals with a CTTrest ≥ 25, exercising at a level of 30%-40% CTTrest would place them in moderate to vigorous exercise intensity range. A high degree of reliability was demonstrated utilizing the CTT method across the various modes of aerobic exercise. As such, independent of exercise mode, the CTT was found to be an easy and consistent method for prescribing moderate to vigorous aerobic exercise intensity.
