endurance
It is shown that the rigidity and heat endurance of cryogels rise with an increase in the concentration of initial PVA solution and a decrease in the rate of thawing.
      
Based on this information, the integral self-rating of the intensity of the physical load and its endurance is formed in the sensory CNS sphere, with one of the signals to stop the work being the feeling of shortness of breath.
      
The relationship between the rheological blood properties and several indices of age-related erythrocyte structure was established in endurance-training athletes (n = 21).
      
Erythrocyte aggregation (examined microscopically in diluted blood), lipid and protein plasma profiles, and fibrinolytic activity were studied in endurance athletes.
      
The main bioenergetic qualities-the alactic anaerobic, glycolytic anaerobic, and aerobic potentials-are the main factors of endurance in athletes.
      
The specific expression of endurance in athletes is determined by the ratio between these bioenergetic parameters.
      
It has been found that the aforementioned criteria of endurance are expressed in different forms in the cases of critical modes of muscular activity and considerably affect performance in representatives of cyclic sports.
      
Free Fatty Acids and Ca2+ in Blood Plasma of Endurance-Trained Athletes after Prolonged Physical Exercise
      
A study was made of the effects of prolonged physical exercise (90 min at a power of 17 kgm min-1 kg-1) on plasma free fatty acids (FFAs), blood Ca2+, oxygen consumption (OC), and body temperature of endurance-trained athletes and untrained subjects.
      
Electrocardiographic studies were performed in 85 endurance-training athletes with chronic physical overexertion.
      
The stimulated subjects demonstrated a marked tendency towards increasing endurance and a significant increase (by 10%) in both succinate dehydrogenase activity and the percentage of muscle fibers containing slow myosin heavy chain (MHC) isoforms.
      
The results of this study may be used for professional selection or development of criteria of the endurance of athletes with regard to high cyclic exercise intensities.
      
Dependence of endurance performance on ACE gene polymorphism in athletes
      
The frequency of PPARD allele C (with a higher transcriptional activity compared to allele T) in the group of endurance-oriented athletes (N = 898) was significantly higher than in controls (18.3% vs.
      
Moreover, in the group of endurance-oriented athletes participating in cyclic sports, the frequency of allele C increased with growing skill level.
      
Thus, PPARD allele C was associated with predisposition to endurance performance.
      
It is shown that a decrease in their endurance limit in chloride media is determined by their structure, rather than chemical composition and strength.
      
The criterion is based on the mutual correlation between the metals' relative deformation-dissolution at the strain equal to the fatigue limit on one hand and the degree of decrease in their endurance under the effect of environment on the other.
      
In dependence on endurance, the reaction of chalcones with thiosemicarbazide resulted in chalcone or flavanone thiosemicarbazones, whose structures were proven by 1H NMR.
      
Inspection of Fatigue Defects in Endurance Testing of Half-Axles of Maneuverable Aircraft's Stabilizers by Means of Acoustic Emi
