This study examined the effects of sensory deprivation and music on perceived exertion and affect. Volunteer women (N=24) performed three 18-min sessions on a cycle ergometer at light, moderate, and heavy workloads during which perceived exertion, affect, and heart rate were monitored. Each subject participated in a control, deprivation, and music condition. No significant differences where found in heart rate between conditions. In contrast, significantly lower perceived exertion existed during the music compared to the deprived condition at the low workload. Similarly, there was lower perceived exertion during the music compared to the control condition at the moderate workload. Also, significantly greater levels of affect were observed during the music compared to the deprived condition at the moderate and heavy workloads. It was concluded that the influence of music and deprivation on perceived exertion and affect was load dependent. These results are discussed with regard to informational processing models of sensory and psychological input.

Fitness Level

This study was conducted to investigate the influence of fitness level and gradually increased amounts of exercise on individuals' ratings of perceived exertion (RPE). 20 men served as paid subjects. They were divided into groups of high (>56 ml/kg/min.) and low fitness (<46 ml/kg/min.) according to their maximal oxygen uptake (VO2 max). Participants were required to pedal on a cycle ergometer at a progressively increased workload (every 10 min.) corresponding to 40, 50, 60, 70, and 80% of individual VO2 max values. Heart rates, RPE, and core temperatures were recorded every 5th minute after the initiation of exercising at a specific workload. Analysis indicated that, when controlling for VO2 max values, elevations of heart rate and core temperature were not affected by fitness. However, highly fit individuals perceived themselves under less exertion than did the group low in fitness. Correlations showed that, taking into consideration fitness, there is a stronger relationship between RPE and heart rate and RPE and core temperature for the highly fit individuals than for the less fit.

This study was designed to examine the audience-pleasing and self-constructional aspects of self-presentation on perceived exertion. Subjects performed two 18-min sessions on a cycle ergometer at light, moderate, and heavy workloads, during which perceived exertion and heart rate were collected. Each subject participated in a male and female experimenter condition. Males reported significantly lower perceived exertion in the female experimenter condition at the heavy load, compared to the same load in the male experimenter condition. There were no other significant differences for males or females at any of the workloads in either condition. Responses on the Self-Monitoring Inventory were used to assign subjects to either a high or low self-construction group. Results indicated that high self-constructors recorded significantly lower perceived exertion, compared to low self-constructors, at the low and moderate workloads.

Target Intensity

The accuracy of regularing exercise intensity by Ratings of Perceived Exertion (RPE) was examined. Subjects underwent 4 production trials, 2 on a treadmill (PIA, P1B) and 2 on a cycle ergometer (P2A, P2B). 9 untrained subjects used only their perceptions of effort to regulate exercise intensity. Target intensity was the RPE equivalent to 60% VO2mx. Exercise intensity (VO2) during P1A, P1B, and P2A did not differ from the target, but during P2B was lower than target. During P1A and P1B heart rate did not differ from the target but was lower than target during P2A and P2B. RPE seems a valid means of regulating exercise intensity during repeated bouts of treadmill exercise at 60% VO2max; however, exercise intensity during repeated bouts on the cycle ergometer may be lower than target.

Video Condition

Two studies were conducted to assess whether indoor video-assisted cycling influenced a person's quality of exercise (subjectively and quantitatively), compared to indoor cycling alone. In the first study 12 recreationally active subjects completed an initial test of VO2max, and three randomized trials of cycling at 70% VO2max (35 min.) watching a commercial cycling tape (cycle video), a test pattern displayed on the ergometer screen (blank video), or no video. Subjects' ratings of perceived exertion (RPE) and Affect were recorded, and heart rate and oxygen consumption (VO2) were measured during testing. The second study required 12 different subjects first to complete an assessment of VO2max and then two randomized trials (cycle video and no video) on a cycle ergometer where they freely set the intensity of their own exercise. Measurements of VO2, heart rate, blood lactate, power output, RPE, and Affect were recorded during testing. Results of Exp. 1 indicated that subjects' perceived effort equally between the two conditions, yet reported significantly ( p <.05) higher affect at 25 and 35 min. of cycling during the cycle video condition than no video condition. Results of Exp. 2 indicated that despite similar levels of blood lactate, subjects exercised at a significantly higher intensity during the cycle video condition compared to no video condition, with a higher VO2 and heart rate. The data support the use of indoor exercise videos to improve the exercise experience and also to increase the physiological demands of indoor exercise.

Rate Of Perceived Exertion

According to the most customary exercise protocols, core temperature (Tc) rises in parallel with workload (WL) and experimental time. Physiological variables, however, may be related to each of these factors. To investigate effects of WL independent of experimental time and body temperature, we employed four moderate WLs in 4-min steps between 35 and 65% peak O2 uptake (VO2 peak) in randomized order. To investigate independent effects of body temperature, the same work protocol was performed both after resting in comfortable ambient temperature [control test (Cont)] and after a double cold exposure [precooling test (Pret)], where Tc and the temperature set point are decreased by approximately 0.6 and 0.3 degrees C, respectively. Eight male subjects (24 +/- 1.9 yr, VO2 peak 4.9 +/- 0.5 l/min) worked on a cycle ergometer in a climatic chamber. Heart rate (HR) and breathing frequency (BF), but not preferred pedal rate (PR), were positively correlated to Tc, the slopes amounting to 17 and 3.75 min-1/degree C for HR and BF, respectively. The regression appeared linear over the whole temperature range, and the regression lines were not shifted by precooling. PR was increased by time, but Pret-Cont differences of PR and Tc were inversely correlated (r = -0.50, P < 0.01). The effects of WL were highly significant on HR, O2 uptake, and rate of perceived exertion but not on BF, PR, and sweat rate. The relation of rate of perceived exertion to HR was shifted by precooling.

Background:The authors sought to evaluate the acceptability and feasibility of maximal fitness testing in sedentary older individuals at risk for mobility disability.Methods:Maximal cycle-ergometer testing was performed at baseline and 6 and 12 months later in a subset of LIFE-P study participants at the Cooper Institute site. The mean age of the 20 participants (80% female) tested was 74.7 ± 3.4 years. The following criteria were used to determine whether participants achieved maximal effort: respiratory-exchange ratio (RER) ≥1.1, heart rate within 10 beats/min of the maximal level predicted by age, and rating of perceived exertion (RPE) >17.Results:Participants’ mean peak VO2 was 12.1 (3.7) mL · kg–1 · min–1. At baseline testing, only 20% of participants attained an RER ≥1.10, only 35% achieved a peak heart rate within 10 beats of their age-predicted maximum, and 18% had an RPE of >17. Subsequent testing at 6 and 12 months produced similar results.Conclusions:In this pilot study of sedentary older persons at risk for mobility disability, very few participants were able to achieve maximal effort during graded cycle-ergometer testing.

The purpose of this study was to examine the relations of ratings of perceived exertion (RPE) of the legs, chest, and overall body with physiological responses (heart rate and oxygen uptake) both during incremental cycling exercise and the recovery stage (submaximal light exercise after total exhaustion). Subjects were 10 healthy university males ages 18 to 23 years ( M age = 20.5 yr., SD= 1.4 yr.) who performed incremental cycling exercise until exhaustion after 1-min. rest and unloaded cycling for 2 min. They then continued to exercise at a constant load of 30 Watts (used for cooling down; recovery stage) for a total of 25 min. Oxygen uptake and heart rate were measured, and three types of RPE were done; Respiratory (chest; RPE-R), Peripheral (legs; RPE-P), and Overall (overall body; RPE-O) during the exercise and recovery stage. All variables during exercise and RPE-R and RPE-P during recovery stage showed significant linear changes. RPE-O and physiological exercise intensity (oxygen uptake and heart rate) in the recovery stage showed significant curvilinear changes (quadratic). RPE-P were significantly higher than RPE-R both during exercise and the recovery stage and the variables highly correlated ( r ≥.88, p <.05). At the point of exhaustion, RPE-P and RPE-O almost reached a peak, but RPE-R did not. In the exercise period until exhaustion, the regression coefficient of RPE-R (.38) was significantly lower than that of RPE-P (.56) and RPE-O (.50), and RPE-R increased according to an increase of the incremental load, but the amount was significantly lower than those of RPE-P and RPE-O. In the recovery stage after exhaustion, the regression coefficient of RPE-O (−1.35) was significantly greater than that of RPE-P (−1.07). A decrease in RPE-O corresponded to a decrease in heart rate and oxygen uptake, but RPE-P did not, and the recovery of RPE-P tended to be late. The results suggest that relations for the physiological responses of heart rate, oxygen uptake, and RPE, and between each RPE in the recovery stage differed from those during exercise until exhaustion.
