Objective. To compare resistance bouts performed to failure atlow (60% 1RM) and high (90% 1RM) workloads for acute rate of perceived exertion (RPE) (per exercise), session RPE (S-RPE) (30 min post), HR (per exercise) and total work (per session, and per exercise).Background. RPE is a convenient method for quantifying intensityin aerobic exercise. However, RPE has recently been extended to exercise modalities dominated by anaerobic pathways such as resistance training (RT). Method. Subjects (N=12) were assessed using an exercise-specific1 repetition maximum (1RM) for 6 exercises. On separate days in a counterbalanced order, subjects performed 3 sets of each exercise to volitional failure at a low intensity (LI) and a high intensity (HI) with 2 minutes rest between sets and exercises. At the end of each set, subjects estimated acute RPE for that set using a 10-point numerical scale. Thirty minutes after the end of the exercise session subjects estimated their S-RPE for the entire workout. HR, total work, and acute RPE were compared (HI v. LI) using repeated measures ANOVA.Results. A paired samples t-test showed LI was significantly higher(p=0.039) than HI for session RPE (LI=8.8±0.8, HI=6.3±1.2) andtotal work (LI=17461±4419, HI=8659±2256) (p=0.043). Per exercise,total work and acute RPE were significantly greater (p=0.01) for LI for all exercises. Peak HR was significantly higher per exercise during LI for leg press (p=0.041), bench press (p=0.031), lat pull-down (p=0.037) and shoulder press (p=0.046).

“…[22][23][24][25][26] Test-retest reliability and validity of the Borg RPE has previously been established. 27 Test-retest reliability for the four submaximal tasks in our lab is r ¼ 0.80 for exercise economy, r ¼ 0.93 for ventilation, and r ¼ 0.96 for heart rate. Since maximum heart rate, ventilation, and RPE differed according to age, fitness level, and in the case of RPE race (Black women reported significantly lower RPE than White women at the end of the maximum treadmill exercise test), each of the difficulty measures for these submaximum tasks was adjusted for maximum values from the VO 2 max test.…”

PURPOSE:The purpose of this work was to determine if racial differences in maximum oxygen uptake (VO 2 max) and difficulty in doing submaximum (sub) exercise tasks contribute to activity-related energy expenditure (AEE) and activity-related time equivalent (ARTE) index, an index of time spent in physical activity. METHODS: Subjects were 35 Black and 39 White sedentary premenopausal women group matched for age, weight and body composition. Percent fat was determined by dual energy X-ray absorptiometry, AEE by doubly labeled water and sleeping energy expenditure, ARTE index by AEE and energy cost above sleeping for five exercise tasks, and VO 2 max by a graded exercise test. Subexercise oxygen uptake was measured during walking at 3 mph on the flat and up a 2.5% grade, climbing stairs, and riding a bike ergometer at 50 W. Difficulty of exercise was assessed during the subexercise and taken as heart rate, ventilation, and ratings of perceived exertion (RPE) and expressed as a % of the individual's maximum. RESULTS: VO 2 max was related to AEE (r ¼ 0.29, Po0.04) and to ARTE index (r ¼ 0.37, Po0.01). All three difficulty measures were related to AEE (r ¼ À0.35 to À0.42, P-valueso0.02) and the ARTE index (r ¼ À0.49 to À0.52, all P-valueso0.01), with the exception of RPE with ARTE (r ¼ À0.27, P ¼ 0.10). Compared to Black women, White women had significantly higher VO 2 max (12%), AEE (45%) and ARTE (50%), and significantly less physiologic difficulty of performing the subexercise tasks: heart rate (5%), ventilation (13%), and RPE (8%). Significant racial differences in AEE and ARTE disappeared after adjusting for any of the three difficulty measures. CONCLUSIONS: These results show that more participation in free-living physical activity is related to greater VO 2 max and less difficulty in being active. In addition, lower levels of physical activity found in Black women may be partially explained by lower VO 2 max and increased difficulty of engaging in physical activities.

“…However, there is evidence of child-adult similarities in the RPE during exercise at intensities below, at and above Th vent (Mahon et al 1997). A dierence between groups may have been expected if Th vent occurred at a higher percentage of O 2 max in the children, since RPE is related to the percentage of O 2 max utilized during exercise (Ekblom and Goldbarg 1971;Skinner et al 1973). However, this was not the case in the present study.…”

The purpose of this study was to examine overall, leg and chest ratings of perceived exertion (RPE) at ventilatory threshold (Thvent) in 16 children (mean age 10.9 years) and 17 adults (mean age 24.3 years). Thvent and maximum oxygen consumption (VO2max) were measured during a graded exercise test on a cycle ergometer. Overall, leg and chest RPE were obtained at the end of each exercise stage. VO2max was 49.9 (8.5) and 47.1 (6.1) ml x kg(-1) x min(-1) [mean (SD)] in the adults and children, respectively (P > 0.05). Relative to VO2max, Thvent was 61.7 (5.3)% in the adults and 64.7 (5.2)% in the children (P > 0.05). Overall, leg, and chest RPE values at Thvent for the adults were 11.5 (2.6), 11.9 (2.5), and 10.5 (2.5), while for the children these values were 13.6 (2.2), 14.1 (2.2), and 12.6 (2.3), respectively. All RPE values were higher for the children (P < 0.05). These results suggest that children are able to discriminate levels of exertion in different parts of their body during graded exercise. Furthermore, children rate an intensity corresponding to Thvent to require a greater overall, leg and chest effort than adults exercising at a similar intensity. This indicates that children experience more pronounced cardiorespiratory and muscular sensations during this type of exercise.
