 note = {Effects of exercises and sleep deprivation on serum zinc were studied in 8 healthy male volunteers with a mean age of 44 (experimental group). Circadian rhythm of serum zinc was also studied in other 7 subjects without exercises or sleep deprivation (control group). Submaximal exercises were conducted with a bicycle ergometer. Exercises were repeated at 6 pm on the 1st day, at 6 am, 12 pm, and 6 pm on the 2nd day and at 6 am and 6 pm on the 3rd day. Subjects of the experimental group were not allowed to sleep at night on the 1st day, but slept for 8h on the 2nd day. Blood was drawn before and after each exercise. In the control group, blood was drawn before each meal and at midnight. Serum zinc was above the mean from 6 am to 6 pm and below the mean at midnight on the 2nd day. It was above the mean at 6 am and below the mean at 12 pm and 6 pm on the 3rd day. There were no significant differences in serum zinc before and after exercises. Sleep deprivation, on the other hand, significantly depressed serum zinc. Serum zinc has a circadian rhythm, highest in the early morning and lowest in the midnight. Sleep deprivation, but not exercise lowered serum zinc. To assess the zinc status by the serum zinc, these factors should be considered.},
