This study examined differences in consciousness indexes (perceived duration of time) at different levels of physical exertion within the framework of Newman's model of health and with emphasis on Prigogine's theory of dissipative structures. The sample consisted of 100 volunteers participating in regular aerobic exercise. Instruments included 817E Monarch Stationary Bicycles, 1800 Dynamap Automatic Blood Pressure/Pulse Monitors, the production method of time estimation, and the Perceived Exertion Scale. Repeated measures ANOVA revealed significant differences in consciousness indexes during exertion (p less than .00001). Paired t-tests yielded significant differences between the resting consciousness index and consciousness indexes at preferred, increased, and decreased exertion levels (p = .000). Results indicate that the consciousness index decreased with physical exertion regardless of actual exertion level. In addition, changes in perceived exertion and in physiological parameters suggest a pattern of expanding consciousness that is consistent with the theoretical framework.
