[Effect of exercise on vitamin A utilization by rats].
The effect of exercise was studies on vitamin A utilization by rat organism. The biological experiment was done using 64 growing Wistar rats with initial vitamin A levels in the liver 380 and 790 i.u. The rats were subjected during 12 days to 30, 60 and 90 minute exercise on moving track at 20 m/min speed. The rats were exercised in groups. During the experiment they were given water and food ad libitum but without vitamin A, for controlling its intake. The measure of vitamin A utilization by rat organism after its addition to the diet was determination of its level in plasma, liver and kidneys. No evident differences were found in diet intake and body mass and in vitamin A levels in plasma and kidneys in the groups of rats differing in exercise duration. Increased duration of the exercise reduced vitamin A content in the liver, and this reduction was significant in the group subjected to exercise during 90 minutes daily.
