The effect of natural training and electrostimulation on changes of alanine transaminase and aspartate transaminase activity in rat skeletal muscles.
Wistar rats were trained on a moving track or/and had stimulation of the crural muscles with electric current of 50 Hz frequency for 14 days. Dramatic changes were observed in the activity of alanine transaminase (AlAT) and aspartate transaminase (AspAT), which was particularly pronounced during 16 days of follow-up after completion of training and stimulation. Persisting high activity of the enzymes in the white muscle fibres exceeding 2-3 times the control values showed a significant effect of electrostimulation on the metabolism of amino acids enabling the muscles to obtain energy for contraction from non-glycolytic source.
