Sotomaior BB, da Silva JKF, Enes AAN, Palumbo DP, Carneiro CF, Osiecki R. Correlation between the Heart Rate Deflection Point and the Rating of Perceived Exertion Threshold in an Arm Ergometer Protocol. JEPonline 2018;21(4):143-149. The purpose of this study was to verify the intensity of occurrence of the heart rate deflection point (HRDP) and the rating of perceived exertion threshold (DmaxRPE) in college students and to verify its correlation in the arm ergometer. Twelve male college students (age = 21.15 [+ or -] 3.13 yrs, weight = 80.79 [+ or -] 11.1 kg, height = 175.13 [+ or -] 3.84 cm, and body fat = 13.9 [+ or -] 3.86%) were subjected to a continuous test with an arm ergometer with initial workload of 12.5 W with increments of 5 W every 1 min until voluntary exhaustion. No meaningful differences in the intensity of occurrence of HRDP and DmaxRPE and the HR values related to HRDP and DmaxRPE (P>0.05) were found. Significant correlation was found between the intensity of occurrence of the HRDP and DmaxRPE (r = 0.887, P
