摘要：

1. The aim of this study was to find out whether the anaerobic threshold (AT) can be estimated in rats running at increasing speed and if so what is the reproducibility of the measurements. 2. Lactate (LA) concentrations in blood taken from 11 rats were determined during a discontinued, multistage treadmill exercise test repeated four times in each animal. 3. It was found that blood LA changes vs speed have an exponential pattern with a distinct, rapid rise at the speed above 25 m/min which corresponds to blood LA of approx. 4 mmol/l. 4. The variation coefficient of the speed at which AT occurred in individual animals ranged between 10 and 20%. 5. These results offer a potential application of AT determination in the animal studies concerning mechanisms controlling exercise metabolism.
