Outline

Text

Objective: Better performance is often related to lactate clearance from the blood. The increase in blood lactate levels during exercise is reduced by acclimatization. The aim of our study was to examine the relationship of training to physical performance by lactate determination.

Material/Methods: For a control group we examine 24 male sedentary volunteers of age 25±3 years exposed to treadmill stress test up to sub-maximum heart rate level (I group). A number of 28 male physically active subjects were examined (21±2 years old). They were divided in 2 groups: II – exposed to treadmill stress test for 20 minutes (n=13) and III – exposed to cycle ergometer for 15 minutes (n=15). For the lactate test the photometric enzyme method by Boehringer Mannheim was used.

Results: Increase of lactate concentration was found: in the I group from 2.71±1.5 to 12.59±3.2 μmol/L (p<0.01); in the II group from 3.17±1.6 to 9.31±3.2 μmol/L (p<0.05); and in the III group from 2.36±2.2 to 6.63±2.3 μmol/L with no significant difference.

Conclusion: In the study, the pattern of lactate increase due to exercise is described. From the obtained results we may conclude that lactate variable is highly correlated with the physical performance. There is a strong relationship between lactate and its related variables: condition level and exercise type performance, respectively.
