Oxygen Transport System

The study of the dependence of the dynamics of change of indicators of the gas transportation system from the power of physical exercise in the athletes of different sports was carried out. It was identified non-linear character of changes at speed - increasing workload, strong and positive correlation with the load power and their relationship at various levels of maximal oxygen consumption. The regression equations derived in the form of polynomials of the third degree, describing the revealed features with a high degree of importance were presented. The coefficients of regression equations define the peculiarities of dynamics of parameters of separate links of the gas transportation system when increasing the load capacity. It was established that representatives of cyclic sports with a high level aerobic capacity for oxygen consumption, in conditions of step-increasing load to the level of maximum oxygen consumption equally optimally functioning links of the gas transportation system, which provides the delivery of oxygen and its disposal at the limiting physical activity at various stages of its implementation in comparison with the representatives of acyclic sports. The obtained results are consistent with survey data of reactive types of oxygen transport systems of the body at a maximum physical load. The authors suggest to using them in evaluating the functional possibilities of the oxygen transport system with subsequent identification of the factors limiting the maximum oxygen consumption at full load.

In the study, we investigated the association of polymorphic locus CMA 1/B (G1903A) with indicators of oxygen transport system of the body. To determine the nucleotide substitutions in the gene CMA1/B, we used RFLP- analysis, PCR products were digested with the restriction enzyme BstXI. Analysis of the distribution of frequencies of alleles and genotypes CMA1/B showed statistically significant differences in the frequency of polymorphic variants of genotypes between athletes and controls. Athletes have predominant genotype A/A (0,52), and G/G (0,4), whereas in the control group, the most common genotype A/G (0,58). Using factor analysis, we revealed differences in the structure of the association between indicators of oxygen transport system depending on the genotype of the gene CMA. It was revealed the association of polymorphic gene variants with red blood parameters, hemodynamic and respiratory systems, as well as with physical endurance and tolerance to the muscular load. The closest connection between the studied traits detected at polymorphic variants CMA A/A. At this genotype physical endurance largely depends on the state of the circulatory system and the respiratory system functional reserves. It was also shown the correlation between adaptive capabilities of cardiovascular system and efficiency of the heart functioning with the level of motor activity. The interaction complex of the features that characterize the activities of the cardiorespiratory system, system, causes the formation of the final phenotype, which obviously explains the detected frequency distribution of different genotypes in athletes.

Background and Study Aim: The somatotype determines not only physical development, but also the functional capabilities of the organism. Investigation of the correlation relations between the component of body and VO2 max will reveal the influence of each of the components on the aerobic capacity of men in the first period of mature age. The aim of the work – to detect the peculiarities of manifestation of maximum oxygen consumption of men with different somatotypes and to investigate the relationship with the component composition of the body. Material and Methods: The study involved 150 men aged 25-35 years. The somatotype was determined by the Heath-Carter method. The component composition of the body was determined by the bioelectrical impedance method. The VO2 max indicator was determined, metered loads were performed on a bicycle ergometer. A correlation analysis of the absolute and relative VO2 max values with the fat and muscle components of the body was performed. Results. A high degree of inverse correlation between the relative VO2 max indicator with body mass in men of mesomorphic somatotype was established and a high degree of inverse correlation between the relative VO2 max indicator with body mass and BMI in men of endomorphic-mesomorphic somatotype. Conclusions: For representatives of the mesomorphic and endomorphic-mesomorphic somatotype, a larger body mass and a high degree of correlation between body mass and relative VO2 max indicator are characteristic. For representatives of the ectomorphic and balanced somatotype, a smaller body mass and a lower degree of correlation between body mass and relative VO2 max indicator max are characteristic.

Tanaka, T., Y. Ohira, M. Danda, H. Hatta, and I. Nishi.Improved fatigue resistance not associated with maximum oxygen consumption in creatine-depleted rats. J. Appl. Physiol. 82 (6): 1911–1917, 1997.—Effects of feeding of either creatine or its analog β-guanidinopropionic acid (β-GPA) on endurance work capacity and oxygen consumption were studied in rats. Resting high-energy phosphate contents in hindlimb muscles were lower in the β-GPA group and higher in the creatine group than in controls. The glycogen contents in resting hindlimb muscles of rats fed β-GPA were significantly higher than those in controls. The endurance run and swimming times to exhaustion were significantly greater (32–70%) in the β-GPA group than in the control and creatine groups. However, there were no beneficial effects on the maximum oxygen consumption (V˙o 2 max) and oxygen transport capacity of blood by the feeding of β-GPA. None of these parameters were significantly influenced by creatine supply. Both maximum exercise time andV˙o 2 max in the β-GPA group were not changed by normalization of glycogen levels. The activities of mitochondrial enzymes in skeletal muscles were higher in the β-GPA group than in the controls. Thus endurance capacity is improved if the respiratory capacity of muscles is increased, even when the contents of high-energy phosphates in muscles are lower. Increased endurance capacity was not directly associated with the elevated levels of muscle glycogen, oxygen transport capacity of blood, orV˙o 2 max.

Oxygen Transport System

1. The capabilities of the oxygen transport system of rainbow trout in supplying the increased oxygen demands in exercise, in a water tunnel at 9–10.5 °C, have been investigated by increasing the velocity of water flow, with a 1 h period between increments, up to the maximum swimming speed (critical velocity, Ucrit). 2. At Ucrit, NO2 was elevated above the resting level by 7.5 times. The logarithm of NOO2 was linearly related to the swimming speed expressed as a proportion of Ucrit. Vg increased in almost direct proportion to the increase in NOO2. 3. Heart rate rose slightly at half Ucrit and reached a maximum, 1.6 times the resting rate, as Ucrit was approached. Ventral and dorsal aortic mean blood pressures rose by 60% and 20% respectively at Ucrit while their pulse pressures doubled. Central venous pressure was virtually unchanged. 4. P a, Oa, O2 fell slightly during exercise but Ca, Oa, O2 was unaffected. On the other hand Pv, Ov, O2 halved and Cv, Ov, O2 fell from 3.17 (S.E. = 0.3) to 0.6(S.E. = 0.7) mmol/1. Cardiac output increased by about 3 times resting values. 5. The results are discussed and an attempt is made to estimate the maximum capabilities of the components of the oxygen transport system in sustained exercise.
