title: An influence of exercise of increasing intensity on aminotransferase activity and electrolyte level in red blood cells and blood serum in men with average and very high physical working capacity.
abstract: Healthy subjects with average and very high physical working capacity were submitted to two 6-min periods of work on a cycloergometer at the work loads 70 and 90 percent VO2max. Changes in the activity of Asp AT and Al AT as well as in the concentrations of NA, K and lactates in erythrocytes and serum were determined. In the subjects with average physical working capacity the serum concentrations of lactate and sodium, as well as the activity of Asp AT were much more increased than in the highly efficient subjects. In both groups similar changes of electrolyte concentrations in erythrocytes occured. The activity of Al AT was increased only in the group of subjects with high physical working capacity after the first period of work and showed a tendency to return to the resting values after the second period.
