Full textThe main goal of this study was to investigate excess oxygen consumption above the anaerobic (VT) threshold during a maximal incremental exercise test and the slow component of VO2 kinetics during a constant intensity exercise test. 45 elite cyclists were recruited to perform two separate tests with maximal incremental and constant intensity (3 bouts x 10 min exercise with intensity 25 W < VT, = VT, and 25 W > VT). 12 subjects showed no significant changes in oxygen consumption slope above VT. However 15 subjects demonstrate a significant increase in oxygen consumption slope and 18 showed a significant decrease in oxygen consumption slope. Nonlinear regression modelling was also used to analyse oxygen consumption data. It showed that the exact time of changes in oxygen consumption is independent of the anaerobic threshold. These results present a new theory for VO2 kinetics and suggest that further investigations are required. The oxygen consumption kinetics was also investigated during 3 constant intensity exercise tests with fast and slow adaptation components by bi-exponential model. In contrast with previous studies the magnitude of oxygen consumption during slow components was neither 200 ml/min nor 10% of fast adaptation. The Gaussian model was also applied to oxygen consumption kinetics and appeared to model oxygen consumption slopes better than the bi-exponential model (higher R²), suggesting an adaptive mechanisms to energy requirements rather than a slow excess of VO2

Full textThe aim of this thesis was threefold 1)- To study the ventilatory function during a maximal incremental exercise and a prolonged submaximal exercise in athletes with sickle cell trait (SCT), 2)- To study the performance of the ventilatory function during a constant load exercise in subjects with minor β-thalassemia, 3)- Evaluate the physiological adaptation during prolonged submaximal exercise in athletes with heterozygous sickle cell disease. The first study showed that maximal incremental exercise and constant load exercise induce spirometric fatigue, and decreased strength and endurance of the respiratory muscles in subjects with sickle cell trait. Rectangular exercise significantly affects respiratory muscle strength and endurance than triangular exercise. The second study was showed an impairment of the performance of ventilatory function after performing prolonged submaximal exercise in subjects with minor β-thalassemia. Thus, a significant decrease in the endurance of the respiratory muscles was observed in these pathological individuals in response to constant load exercise compared to healthy subjects. These results confirm that hemoglobinopathic subjects do not have the ability to maintain high levels of ventilation during intense physical exercise. Then, in the third study, the determination of the MAP confirmed that the heterozygous form of sickle cell disease is not a limiting factor in maximal aerobic physical fitness. Adaptation to submaximal effort, assessed by the rapid phase, is perfectly normal in subjects with sickle cell trait. In contrast, the amplitude of the slow component of VO2, which is higher in SCT, suggests that these pathological individuals are characterized by weak tolerance to exercise. This rise was correlated with HbO2 and HHb which were satble during exercise. This stability confirms the generation of the vascular remodeling mechanism in SCT in response to hemorheological problems produced by exercise. An precocious increase in RMS and a 25.63% linear decrease in MPF correlated with HHb, were observed during exercise in pathologic individuals compared to subjects without hemoglobinopathy, affirming that the decrease in erythrocyte deformabilities which are generally reported in subjects with sickle cell trait disrupts the muscular microcirculation in an increased manner which could be responsible for the slow component of VO2. These results show that subjects with hemoglobinopathy could have a less efficient ventilatory function during intense physical exertion than healthy subjects. Also, these individuals might have more significant peripheral muscle fatigue than subjects with normal hemoglobin and stable muscle oxygenation during rectangular exercise. They exhibit aerobic capacity and tolerance to endurance effort inferior than healthy subjects during submaximal effort
