    Physical exertion decreases the consciousness index, affecting perceived time. This study explored consciousness during aerobic exercise, finding significant changes regardless of exertion intensity.

    Area of Science:

    • Physiology
    • Psychology
    • Complexity Theory

    Background:

    • Newman's model of health emphasizes holistic well-being.
    • Prigogine's theory of dissipative structures explains self-organization in complex systems.
    • Understanding consciousness during physical exertion is crucial for health and performance.

    Purpose of the Study:

    • To investigate how physical exertion affects consciousness indexes, specifically the perceived duration of time.
    • To analyze these effects within the theoretical frameworks of Newman's model and Prigogine's theory.
    • To correlate changes in consciousness with perceived exertion and physiological parameters.

    Main Methods:

    • 100 volunteers engaged in regular aerobic exercise.
    • Measurements included stationary bicycles, blood pressure/pulse monitors, time estimation, and perceived exertion.

  • Repeated measures ANOVA and paired t-tests analyzed consciousness indexes at rest and various exertion levels.

    • Main Results:

    • Significant differences in consciousness indexes were observed during physical exertion (p < .00001).
    • The consciousness index decreased with physical exertion, irrespective of intensity (p = .000).
    • Changes in perceived exertion and physiological data indicated expanding consciousness.

    Conclusions:

    • Physical exertion demonstrably alters the consciousness index, specifically reducing the perception of time.
    • The observed changes align with theories of complex systems and expanding consciousness.
    • This suggests a dynamic interplay between physical activity, perception, and physiological states.
