| Resumen |
Results of observations made in 3 groups of 5 subjects (age 20 to 28). The first 4 days of the experiment they slept at night and worked during the day, on the 5th night they slept 3h before starting a 10-day period in which the cycle was altered by 12h. The total fatigue for the awake periods was not altered; the times within days for greatest fatigue were changed and 9 days were required for a complete reversal of the daily pattern. Mean rephasal times varied for different parameters in ascending order as follows: heart rate, norepinephrine, epinephrine, potassium, sodium, internal body temperature, and 17-ketosteroids. Performance data were based on the Civil Aeromedical Institute Multiple Task Performance Battery. No critical tasks should be performed during the first awake period following a 12-h change. After the first full sleep, performance is satisfactory. For the first week after the change, 8h should be the maximum working period. |
