Utilisation des substrats énergétiques à l'exercice chez la femme : influence de la contraception orale, de la prise alimentaire et de la localisation des graisses

Isacco, Laurie 07 June 2012 (has links)
La production endogène ou la prise exogène d’hormones sexuelles chez la femme génère un climat hormonal qui lui est propre. Ces particularités endocriniennes influent sur la composition corporelle et modifient les sécrétions et/ou la sensibilité de certaines hormones clés du métabolisme énergétique pouvant conduire à une utilisation spécifique des substrats énergétiques à l’exercice. L’objectif de ce travail était d’étudier l’influence d’une contraception orale (CO : mini dosée monophasique), de la prise alimentaire pré-exercice et de la localisation des graisses sur les réponses métaboliques et hormonales de la femme préménopausée et normo-pondérée à l’exercice (45 min à 65% de O2max). Nos résultats ont montré que la prise d’une CO ne modifiait pas les réponses métaboliques et hormonales et l’utilisation des substrats énergétiques à l’exercice quel que soit le statut nutritionnel des sujets (exercice à jeun ou en situation postprandiale). Cependant, à l’exercice, une situation de jeûne a favorisé une augmentation de l’oxydation lipidique et cela quel que soit le statut hormonal des sujets (CO+ ou CO-). En situation postprandiale, l’exercice physique a stimulé l’activité lipolytique chez des femmes CO+ et CO- sans distinction entre les deux groupes. Enfin, quand l’utilisation des substrats énergétiques à l’exercice est appréhendée en fonction du rapport de la masse grasse abdominale/masse grasse des membres inférieurs (A/MI), nos travaux ont montré une augmentation de la mobilisation et de l’oxydation des lipides chez les femmes présentant un plus faible rapport A/MI (malgré des masses corporelles et des tours de taille normaux). Ainsi, au sein d’une population féminine normo-pondérée, les CO minidosées monophasiques ne semblent pas influer sur l’utilisation des substrats énergétiques à l’exercice, alors que la prise alimentaire pré-exercice et la localisation des graisses semblent avoir un impact plus important sur le métabolisme énergétique à l’exercice. / In the female population, sexual hormones (endogen production or exogenous consumption) induce particular hormonal status leading to specific body composition and metabolic and hormonal responses at rest and during exercise. The aim of this work was to determine the influence of oral contraception (low dose monophasic combined OC), pre-exercise food intake and body fat mass localization on metabolic and hormonal responses during exercise (45 min at 65% of O2max) in normal weight premenopausal women. Our results showed that OC did not alter substrate mobilization and oxidation during exercise (in fast and postprandial conditions). However, during exercise performed in fast condition, women exhibited greater lipid oxidation rates whatever their hormonal status (OC+ vs OC-). In postprandial condition, exercise increased lipolytic activity in OC+ and OC- women without differences between both groups. Finally, it has been observed that abdominal to lower body (A/LB) fat mass ratio influenced substrate mobilization and oxidation in premenopausal women with normal weights and waist circumferences. Subjects with a lower ratio exhibited greater lipid mobilization and oxidation than those with a higher ratio. Therefore, in normal weight women, low dose monophasic combined OC do not appear to influence substrate oxidation whereas pre-exercise food intake and body fat mass localization may have an important impact on substrate metabolism during exercise.

BIRTHWEIGHT AND SUSCEPTIBILITY TO CHRONIC DISEASE

Issa Al Salmi Unknown Date (has links)
The thesis examines the relationship of birthweight to risk factors and markers, such as proteinuria and glomerular filtration rate, for chronic disease in postnatal life. It made use of the Australian Diabetes, Obesity and Lifestyle Study (AusDiab). The AusDiab study is a cross sectional study where baseline data on 11,247 participants were collected in 1999-2000. Participants were recruited from a stratified sample of Australians aged ≥ 25 years, residing in 42 randomly selected urban and non-urban areas (Census Collector Districts) of the six states of Australia and the Northern Territory. The AusDiab study collected an enormous amount of clinical and laboratory data. During the 2004-05 follow-up AusDiab survey, questions about birthweight were included. Participants were asked to state their birthweight, the likely accuracy of the stated birthweight and the source of their stated birthweight. Four hundred and twelve chronic kidney disease (CKD) patients were approached, and 339 agreed to participate in the study. The patients completed the same questionnaire. Medical records were reviewed to check the diagnoses, causes of kidney trouble and SCr levels. Two control subjects, matched for gender and age, were selected for each CKD patient from participants in the AusDiab study who reported their birthweight. Among 7,157 AusDiab participants who responded to the questionnaire, 4,502 reported their birthweights, with a mean (standard deviation) of 3.4 (0.7) kg. The benefit and disadvantages of these data are discussed in chapter three. The data were analysed for the relationship between birthweight and adult body size and composition, disorders of glucose regulation, blood pressure, lipid abnormalities, cardiovascular diseases and glomerular filtration rate. Low birthweight was associated with smaller body build and lower lean mass and total body water in both females and males. In addition low birthweight was associated with central obesity and higher body fat percentage in females, even after taking into account current physical activity and socioeconomic status. Fasting plasma glucose, post load glucose and glycosylated haemoglobin were strongly and inversely correlated with birthweight. In those with low birthweight (< 2.5 kg), the risks for having impaired fasting glucose, impaired glucose tolerance, diabetes and all abnormalities combined were increased by 1.75, 2.22, 2.76 and 2.28 for females and by 1.40, 1.32, 1.98 and 1.49 for males compared to those with normal birthweight (≥ 2.5 kg), respectively. Low birthweight individuals were at higher risk for having high blood pressure ≥ 140/90 mmHg and ≥ 130/85 mmHg compared to those with normal birthweight. People with low birthweight showed a trend towards increased risk for high cholesterol (≥ 5.5 mmol/l) compared to those of normal birthweight. Females with low birthweight had increased risk for high low density lipoprotein cholesterol (≥ 3.5 mmol/l) and triglyceride levels (≥ 1.7 mmol/l) when compared to those with normal birthweight. Males with low birthweight exhibited increased risk for low levels of high density lipoprotein cholesterol (<0.9 mmol/l) than those with normal birthweight. Females with low birthweight were at least 1.39, 1.40, 2.30 and 1.47 times more likely to have angina, coronary artery disease, stroke and overall cardiovascular diseases respectively, compared to those ≥ 2.5 kg. Similarly, males with low birthweight were 1.76, 1.48, 3.34 and 1.70 times more likely to have angina, coronary artery disease, stroke and overall cardiovascular diseases compared to those ≥ 2.5 kg, respectively. The estimated glomerular filtration rate was strongly and positively associated with birthweight, with a predicted increase of 2.6 ml/min (CI 2.1, 3.2) and 3.8 (3.0, 4.5) for each kg of birthweight for females and males, respectively. The odd ratio (95% confidence interval) for low glomerular filtration rate (<61.0 ml/min for female and < 87.4 male) in people of low birthweight compared with those of normal birthweight was 2.04 (1.45, 2.88) for female and 3.4 (2.11, 5.36) for male. One hundred and eighty-nineCKD patients reported their birthweight; 106 were male. Their age was 60.3(15) years. Their birthweight was 3.27 (0.62) kg, vs 3.46 (0.6) kg for their AusDiab controls, p<0.001 and the proportions with birthweight<2.5 kg were 12.17% and 4.44%, p<0.001. Among CKD patients, 22.8%, 21.7%, 18% and 37.6% were in CKD stages 2, 3, 4 and 5 respectively. Birthweights by CKD stage and their AusDiab controls were as follows: 3.38 (0.52) vs 3.49 (0.52), p=0.251 for CKD2; 3.28 (0.54) vs 3.44 (0.54), p=0.121 for CKD3; 3.19 (0.72) vs 3.43 (0.56), p= 0.112 for CKD4 and 3.09 (0.65) vs 3.47 (0.67), p<0.001 for CKD5. The results demonstrate that in an affluent Western country with a good adult health profile, low birthweight people were predisposed to higher rates of glycaemic dysregulation, high blood pressure, dyslipidaemia, cardiovascular diseases and lower glomerular filtration rate in adult life. In all instances it would be prudent to adopt policies of intensified whole of life surveillance of lower birthweight people, anticipating this risk. The general public awareness of the effect of low birthweight on development of chronic diseases in later life is of vital importance. The general public, in addition to the awareness of people in medical practice of the role of low birthweight, will lead to a better management of this group of our population that is increasingly surviving into adulthood.
