    Self-rated alertness, not physiological measures alone, predicted performance during bedrest. An "alertness" factor combining both measures improved performance prediction in men undergoing bedrest.

    Area of Science:

    • Physiology
    • Psychology
    • Human Performance

    Background:

    • Bedrest studies are crucial for understanding physiological and psychological changes during inactivity.
    • Assessing the relationship between physiological states and cognitive/motor performance is important for various fields.

    Purpose of the Study:

    • To investigate the relationship between physiological measurements, self-assessed arousal, and performance on memory and dexterity tasks during bedrest.
    • To determine if physiological variables or self-ratings are better predictors of performance.
    • To explore the predictive utility of an "alertness" factor derived from combined measures.

    Main Methods:

    • Eight men participated in a bedrest study over five days.
    • Physiological measurements and self-rated arousal were recorded on days 1, 3, and 5.

  • Performance on memory and dexterity tasks was assessed on day 3.
  • Univariate and principal components analyses were employed.

    • Main Results:

    • No single physiological variable consistently predicted or correlated with performance.
    • Self-rated arousal scores effectively predicted subsequent performance.
    • An "alertness" factor, combining physiological and self-rated data, showed improved performance prediction.
    • Significant inter-subject variability in performance was observed, potentially due to common temporal trends.

    Conclusions:

    • Subjective self-assessments of arousal are valuable predictors of performance during bedrest.
    • A combined "alertness" factor offers enhanced predictive power for performance compared to physiological measures alone.
    • Variability in performance suggests complex interactions and potential confounding factors in bedrest studies.
