Relationships between RPE and HR The relationships between RPE and HR could be described by the same linear regression including all the exercises (160 and 240 W; 5 th and 10 th minutes): RPE = - 0.998 + 0.0935 HR r=0.729; n = 132; p<0.001 Although one or several dummy variables corresponding to APO (D 1 ), time (D 2 ) and protocol (D 3 ) were included in multiple regressions, the effects of D 1 and D 2 on RPE were always highly significant (p<0.001).
