The effects of intake of oyster extract in pill form on various parameters of physical condition including the basal metabolic rate and arterial pulse wave were studied in 5 male students (mean age, 19.8 years.; mean height, 168.4 cm; mean body weight, 61.0 kg; mean 12-minute running record, 2459 .2 m) attending Medical Science College.

The use of drugs was prohibited from one month prior to the beginning of the 10”week experimental period, which lasted from late June to late August in 1983. The first 2 weeks of the period was the control stage, during which no oyster extract pills were administered. For the 4 weeks from the 3rd to the 6th experimental week, the subjects received 12 oyster extract pills every day before breakfast (200 mg x 12; once a day). No pills were given during the 4-week follow-up period from the 7th to 10th week.

On the day before the examination, the subjects took an early dinner, met at the lodging facility in the laboratory before 9 p.m., and went to bed at 10. Blood pressure, arterial pulse wave, oxygen consumption, and basal metabolic rate were measured once a week during the experimental period.

No significant changes were observed in blood pressure.

Compared to the control level (2nd week), arterial pulse wave was elevated in the 3rd week, the week immediately following the start of the administration, as well as in the 6th and the 8th weeks; these increases were all statistically significant (p<0.05).

Oxygen consumption and the basal metabolic rate, calculated from oxygen consumption, decreased notably (p<0.001) during the 5th experimental week (the 3rd week of administration) compared to the control values: significant decreases (p<0.05) were observed again during the 8th week (the 2nd week after the termina- tion of administration). Although responses to oyster extract pills varied among individuals, the basal metabolic rate was generally lowest during the 3rd week of administration.
