Fourty-eight Wistar rats were divided at random into three trained groups and three controlgroups, each consisting of eight rats, 4 females and 4 males. Those in the trained groups swam 30minutes per day, 45 days continuously without break. Then the levels of the serum myoglobin weredetermined for the rats in both the trained and the control groups at rest and under different load.Results showed that, at rest, there was no significant difference in the serum myoglobin between thetrained groups and the control groups after 30-minute swimming, there was no significant increase in serum myoglobin between the trained groups and the control groups either, but after exhaustiveswimming, there was a significant increase in the serum myoglobin between the trained groups and thecontrol groups. Through research made with cortisol as a contrasting indicator, it has now been proved thatserum myoglobin is the sensitive and specific indicator of physical exhaustion.
