The current investigation compared percent of maximal oxygen uptake in recreationally trained (RT) versus untrained (UT) men at selected criterion RPE during graded, treadmill exercise following memory anchoring to the Borg 15-category scale. Eight men were assigned to each group. The RT (23.88 + or - 6.03 yrs.) and UT groups (19.5 + or - 1.77 yrs.) each received memory anchoring instructions. The experimental trial consisted of a graded, treadmill exercise test with small increases in intensity between stages. Linear regression with RPE as the independent variable and oxygen consumption as the dependent variable was used to calculate percent VO sub(2max) for each criterion RPE (7, 9, 11, 13, 15 17, and 19). An independent samples t-test was used to compare percent VO sub(2max) between RT and UT at each criterion RPE. As expected, VO sub(2max) was higher for the RT than the UT. All other descriptive variables were similar between groups. Relative oxygen uptake at each criterion RPE was also similar.
