Abnormalities in the modulation of parasympathetic activity have been identified as a possible pathophysiological link with the association between decreases in heart rate recovery after exercise test. Hypothesis: To investigate if the application of different protocols of active recovery promotes difference in reducing Heart Rate (HR) in Post-Exercise (PE). This was a prospective, randomized trial of patients undergoing Exercise Testing (ET) and applied to two different protocols of active recovery. They were divided into G1 with recovery of 1.5 mph/2.5% and G2 40% of the speed and slope of the peak in the PE. Variables were evaluated pre-test and intrinsic to the TE. We compared the recovery of FC 1 and 2 min in the PE. Statistical analysis used the chi-square test, Student’s t test and considered p<0.05. We analyzed 939 patients and 852 selected for randomization. Were allocated to G1 403 patients with mean age 47.86±14.31 years, 53.35% female and G2 with 449 patients with mean age 48.56±14.23 years and 51.7% were female. In the analysis of HR recovery of first (22.00 Vs. 23.57; p = 0.315) and second (36.17 Vs. 37.70, p = 0.06) minutes, G1 and G2 did not obtain differences. The use of different models of active recovery, applying fixed workload of 1.5 mph/2.5% slope or individually in 40% of the workload of the peak stress does not alter the recovery of HR in first or second minutes in the PE.
