A b st r a ctThe purpose of this study was to develop a virtual cycling system and examine the in uence of virtual reality (VR) on test performance during clinical exercise testing. We aimed to compare the physiological responses of the cardiovascular and ventilatory systems during incremental exercise testing with or without VR, and to measure VR effects on the ratings of perceived exertion (RPE) and cycling duration throughout the test.Twelve healthy senior citizens (ten men and two women) with a mean age of 74.5 6 4.7 years participated in the study. The codes of behavior for this study included a maximum graded exercise tolerance test, a submaximal endurance VR exercise, and a submaximal endurance non-VR exercise. A friction-braked cycle ergometer was used to conduct the exercise tests. For the subject's movement speed to create an appropriate environment ow on the display screen, the bike was connected to a personal computer. The cardiorespiratory and hemodynamic parameters were evaluated at both peak and submaximal exertion.The results show that the VR versus non-VR programs did not differ on submaximal and peak exercise responses during the cycling test. However, signi cant differences were observed between the mean values for cycling duration, distance, and energy consumption. The difference between RPE curves for VR and non-VR protocols revealed promising results within 45 min. of cycling (Breslow test, p 5 .06); however, no statistical signi cance was achieved at the test termination (log rank test, p 5 .17).

Self-Reported Low Vitality, Poor Mental Health, and Low Dietary Restraint Are Associated with Overperception of Physical Exertion

et al. 2010

Objective. We investigated whether perceived exertion, in comparison to the physiological response to exercise, was associated with self-reported vitality, mental health, and physical function during daily activities, or weight control behaviors. Design. Weight-reduced, formerly overweight women (n = 126, aged 22–46 years), completed health and dietary control questionnaires, and underwent a treadmill-walking task while heart rate, ventilation, respiratory exchange ratio, and ratings of perceived exertion were recorded. Results. Overperception of exertion (perceived exertion physiological exertion) was inversely associated with vitality (r = −0.190, P < .05), mental health (r = −0.188, P < .05), and dietary control (r values range −0.231 to −0.317, P < .05). In linear regression modeling, vitality or mental health, and cognitive dietary restraint were independently associated with accuracy of perceived exertion, independent of age, ethnicity, and engagement in exercise during weight loss. Each model explained 7%-8% of the variance in accuracy of perceived exertion. Conclusion. Women with low vitality or poor mental health, and poor dietary control may overperceive exertion. Such overperception may be a barrier to engage in physical activity and thus increase susceptibility to weight gain.

Exploring the potential relationship between mindfulness and ratings of perceived exertion.

This study focuses on an evolving, interdisciplinary area of research involving Exercise Science and Clinical Psychology. It investigated the relationship between the perception of present-moment exertion or effort during exercise and a concept called mindfulness. Exertion is commonly measured more objectively using physiological measures (e.g., heart rate) or more subjectively using self-rated Ratings of Perceived Exertion (RPE). Mindfulness is characterized as "present-moment, non-judgmental awareness," or "living in the present."Despite the acknowledged benefits of physical activity, many people find it burdensome, stressful, and emotionally taxing, especially when first starting an exercise program. Based upon previous research, it was hypothesized that mindfulness would affect RPE during exercise, and that people who by nature are "mindful" would perceive exercise-based exertion more accurately, measured by correlating an objective index of physical exertion (heart rate) and RPE. If true, mindfulness training could: 1) reduce the perception of exercise as burdensome; 2) increase motivation to exercise, and; 3) promote safety during exercise by preventing over-exertion.iv Ninety undergraduate and graduate students ages18-23 were recruited from psychology courses for this study. All were fluent in English, physically healthy, and exercised three or more times per week. They completed a series of self-report paper-andpencil questionnaires measuring mindfulness and related psychological factors. Next, they exercised on a treadmill for between 10 and 20 minutes, during which RPE were periodically assessed. Exercise intensity was gradually increased up to a predetermined heart rate level (76% of their age-predicted maximum heart rate) by varying treadmill speed and elevation. Behaviorally, this involved a transition from walking to jogging or running.
