Standard parameters of external respiration at the aerobic–anaerobic transition and above the anaerobic (ventilatory) threshold (AT) were studied in highly trained athletes during an incremental treadmill test. The efficiency of the adaptive response (AR) was inferred from changes in the heart rate and VO2gradients beyond the AT. Several AR types differing(More)
The aim of this work was to detect changes in proteasome pools of brain parts of August rats with monoamine metabolism violations in comparison with that of control Wistar rats. To reveal active proteasome structures, a method of native electrophoresis for the analysis of crude tissue fractions was developed. By means of this method and following Western(More)
Spectral, coherent, and phase analysis within the low-frequency range of ECG records of athletic runners revealed that oscillations of ECG intervals (PQ-, RT-, P–T-, TP, and PP-intervals) were observed during orthostasis. These data were compared with the results of athletic exercise tests performed after the ECG examination. It was shown that the most(More)
