Condition physique objective et perçue chez l’adolescent obèse : évaluation et prise en charge par l’exercice intermittent d’intensité vigoureuse / Objective and perceived physical condition in obese adolescents : assessment and follow-up by vigorous intensity intermittent exercise

Rey, Olivier 01 December 2016 (has links)
Cette thèse porte sur l’évaluation et la prise en charge par l’activité physique d’adolescent(e)s obèses. Deux études ont quantifié leurs réponses psychophysiologiques à un test de course intermittent en 15-15 (Rossi et al., 2009), progressif et maximal. Comparé au test navette de 20m (Léger et al., 1988), la pertinence du test 15-15 pour cette population réside dans la production de réponses physiologiques maximales similaires tout en conduisant à des vitesses supérieures et à une meilleure condition physique perçue. Deux autres études ont évalué les effets d’un programme de 5 semaines d’exercices intermittents d’intensité vigoureuse (VIT) sur la composition corporelle et les conditions physiques objective et perçue d’adolescents obèses. Le programme comprenait 3 séances hebdomadaires de types de VIT différant en durée et en activités physiques et sportives. Des améliorations de la composition corporelle, des capacités fonctionnelles, notamment chez les garçons, et de la plupart des échelles de capacités physiques perçues sont obtenues. Le VIT de longue durée engendre des améliorations rapides et régulières des échelles de capacités physiques perçues / This thesis fits the assessment and follow-up by physical activity of obese adolescents. Two studies measured their psychophysiological responses to an intermittent progressive and maximal running test in 15-15 (Rossi et al., 2009). Compared to the 20 m shuttle run test (Léger et al., 1988), the 15-15 test is considered as relevant for such population as it leads to similar maximal physiological responses, but also to higher speeds and better perceived physical condition of the participants. Two other studies evaluated the effects of a 5 week program of intermittent exercises at vigorous intensity (VIT) on body composition, objective and perceived physical conditions of obese adolescents. The program included 3 weekly VIT sessions that differed in the type and duration of the included sport and physical activities. Improvements were obtained in body composition, functional capacities, particularly among boys, and in most of the scales of perceived physical capacities. The longest VIT sessions led to rapid and regular improvements of all scales of perceived physical capacities

Stanovení modulů pružnosti směsí pro podkladní vrstvy vozovek / Determination of elasticity modulus for base layers

Hepner, Urban January 2018 (has links)
The thesis deals with the experimental determination of the resilient modulus using cyclic triaxial test with the selected unbound mixtures of the base course of the pavement. The aim is to verify whether the proposed modulus-resilient in the regulation TP 170 based on the statisticaly verified data dating several decades ago is still valid in the present. Furthermore, the thesis deals with the dependence between the measured and the calculated values of the modulus resilient Mr from the cyclic triaxial test and the California Bearing Ratio tests. For the classification of the selected materials, further tests are used in the thesis, such as granularity and compaction tests.
