Resumo: | The objective of the present study was to evaluate the impact of the level of physical activity and overweight in offspring of normotensives or hypertensives, as well as to validate a scale of prediction of adherence to physical activity. This thesis was divided into two studies. In Study I, we observed that among the twenty items on the adherence scale, ten presented good reproducibility (Kappa> 0.70, Pearson's correlation> 0.81), good internal consistency (Cronbach's Alpha 0.84), good clarity and discriminant validity (p = 0.0006 vs sedentary, t = 4.12), correlation between the sum of the scale and the Mets (metabolic equivalent) evaluated by IPAQ with r = 0.073 and p = 0.048. In Study II, 114 males, young, physically active and insufficiently active adults, offspring of normotensives or hypertensives, overweight or eutrophic were selected. The IPAQ was used for the level of physical activity, the PSS-10 for perceived stress, the WHOQOL for quality of life analysis. Anthropometric, hematological and biochemical analyzes and systemic oxidative stress evaluations were performed. In addition, blood pressure (BP) recording beat-to-beat using the Finometer?? was used for evaluation of hemodynamic parameters and of heart rate (HRV) and BP variability (BPV). The results showed a higher BMI and % of fat, both by folds and Bioelectrical impedance analysis, in the overweight groups compared to the eutrophic groups, as well as higher weekly caloric expenditure among the active groups in relation to the sedentary groups, independently of the familial history of hypertension (FHH). In the hematological and biochemical profile all groups presented values within the normal range. The BP values were similar between the studied groups, but a lower heart rate was observed in the active groups with a negative FHH. There was no difference in perceived stress levels, but the quality of life was better in the active groups, with lower benefits in the group with a positive FHH. In relation to HRV, the active eutrophic groups, both with a positive and negative FHH, had higher values of RMSSD (cardiac parasympathetic modulation) and lower sympatho/vagal balance in relation to their respective eutrophic sedentary groups, which was not observed in overweight groups. The groups with a positive FHH presented higher values of both simpato/vagal balance (eutrophic and overweight), SAP variance (just overweight) and vascular sympathetic modulation (LF) (eutrophic and overweight) compared to the group with negative FHH, and these differences were attenuated in the physically active group with FHH and overweight. The active eutrophic group with a negative FHH presented better baroreflex sensitivity in relation to their respective sedentary group, which was not observed in the group with a FHH. With regard to oxidative stress, active groups with a negative FHH had lower levels of hydrogen peroxide and nitrites and greater activity of the antioxidant enzyme glutathione peroxidase (just eutrophic) when compared to their respective sedentary groups, which was not observed for the offspring of hypertensives (sedentary vs actives). In addition, these two parameters and the oxidation of proteins (carbonyls) were increased in the overweight and non-overweight groups with a FHH in relation to the eutrophic group with a negative FHH, being attenuated in the active group with FHH and overweight. In conclusion, the scale of adherence to the physical active developed in this study showed good reproducibility, good internal consistency, clarity and discriminating validity. In addition, our results showed that even under normal clinical conditions, a positive FHH, regardless of the presence of overweight, induced autonomic dysfunction and increases in oxidative stress markers that may be precursors of cardiometabolic diseases in this genetically predisposed population. On the other hand, a physically active lifestyle improves HRV, baroreflex and parameters related to redox status in individuals with a negative FHH. Such benefits seem to be attenuated by the positive FHH, but a physically active lifestyle seems to prevent/attenuate the dysfunctions observed in this condition. |

Esta tese foi dividida em dois estudos. No Estudo I, nossos resultados demonstram que entre os vinte itens da escala de ader??ncia, dez apresentaram boa reprodutibilidade (Kappa > 0,70, correla????o de Pearson >0,81), boa consist??ncia interna (Alfa de Cronbach 0,84), boa clareza e validade discriminante (ativos p=<0,0006 vs. Sedent??rios; t= 4,12), Correla????o entre o somat??rio da escala e o Mets (equivalente metab??lico) avaliado pelo IPAQ com r=0,073 e p=0,048. No Estudo II, foram selecionados 114 sujeitos do sexo masculino, adultos jovens, fisicamente ativos e insuficientemente ativos, filhos biol??gicos de pais normotensos ou hipertensos, com sobrepeso ou eutr??ficos. Foram utilizados o IPAQ para o n??vel de atividade f??sica, o PSS-10 para estresse percebido, e o WHOQOL para qualidade de vida. Foram realizadas an??lises antropom??trica, hematol??gicas e bioqu??micas sangu??nea e de estresse oxidativo sist??mica, al??m de registro da press??o arterial (PA) batimento-a-batimento utilizando o Finometer?? para avalia????o de par??metros hemodin??micos e avalia????o da variabilidade da frequ??ncia card??aca (VFC) e da PA (VPA). Os resultados evidenciaram conforme esperado maior IMC e %G tanto por dobras quanto por bioimped??ncia, nos grupos com sobrepeso em rela????o aos eutr??ficos, bem como maior gasto cal??rico semanal entre os grupos ativos em rela????o aos grupos sedent??rios, independentemente do hist??rico familiar de hipertens??o (HFH). No perfil hematol??gico e bioqu??mico sangu??neo todos os grupos apresentaram valores dentro da faixa de normalidade. Os valores de PA foram semelhantes entre os grupos estudados, por??m foi observada menor frequ??ncia card??aca nos grupos ativos com hist??rico negativo de hipertens??o. N??o houve diferen??a para n??veis de estresse percebido, mas a qualidade de vida foi melhor nos grupos ativos, com menores benef??cios no grupo com HFH positivo. Em rela????o a VFC, os grupos eutr??ficos ativos, tantos com HFH positivo quanto negativo, apresentaram valores maiores de RMSSD (modula????o parassimp??tica card??aca) e menores de balan??o simpato/vagal em rela????o aos seus respectivos grupos sedent??rios eutr??ficos, o que n??o foi observado nos grupos com sobrepeso. Os grupos com HFH apresentaram maior balan??o simpato/vagal que os eutr??ficos com HFH negativo. Quanto a VPA, os grupos com HFH positivo, eutr??fico e com sobrepeso, apresentaram valores maiores tanto de vari??ncia de PAS quanto modula????o simp??tica vascular (LF) em compara????o ao grupo sem HFH, e essas diferen??as foram atenuadas no grupo fisicamente ativo. O grupo de eutr??fico ativo com HFH negativo apresentou melhor sensibilidade barorreflexa em rela????o ao seu respectivo grupo sedent??rio, o que n??o foi observado no grupo entre os sujeitos com HFH positivo. Com rela????o ao estresse oxidativo, os grupos ativos com HFH negativo apresentaram menores n??veis de per??xido de hidrog??nio e nitritos e maior atividade da enzima antioxidante glutationa peroxidase quando comparados aos seus respectivos grupos sedent??rios, o que n??o foi observado para os filhos de pais hipertensos. Al??m disto, estes dois par??metros e a oxida????o de prote??nas (carbonilas) estavam aumentados nos grupos com e sem sobrepeso com HFH positivo em rela????o ao grupo eutr??fico com HFH negativo, sendo atenuadas no grupo ativo com HFH positivo e sobrepeso. Em conclus??o, a escala de ader??ncia ao exerc??cio desenvolvida neste estudo apresentou boa reprodutibilidade, boa consist??ncia interna, clareza e validade descriminante. Al??m disto, os resultados evidenciam que mesmo sob condi????es cl??nicas de normalidade, o HFH positivo, independentemente da presen??a de sobrepeso, induz disfun????o auton??mica e aumento de marcadores de estresse oxidativo que podem ser precursores de doen??as cardiometab??licas nesta popula????o geneticamente predisposta. Por outro lado, um estilo de vida fisicamente ativo melhora a VFC, o baroreflexo e par??metros relacionados ao estado redox em indiv??duos com HFH negativo. Tais benef??cios parecem atenuados pelo HFH positivo, mas um estilo de vida fisicamente ativo parece prevenir/atenuar as disfun????es observadas nesta condi????o.Submitted by Nadir Basilio (nadirsb@uninove.br) on 2018-07-19T19:15:24Z No. of bitstreams: 1 M??rio C??sar Nascimento.pdf: 1745805 bytes, checksum: ad4c8a4e2dc9ca8de775e2bd0ca30068 (MD5)Made available in DSpace on 2018-07-19T19:15:24Z (GMT).

description |
The objective of the present study was to evaluate the impact of the level of physical activity and overweight in offspring of normotensives or hypertensives, as well as to validate a scale of prediction of adherence to physical activity. This thesis was divided into two studies. In Study I, we observed that among the twenty items on the adherence scale, ten presented good reproducibility (Kappa> 0.70, Pearson's correlation> 0.81), good internal consistency (Cronbach's Alpha 0.84), good clarity and discriminant validity (p = 0.0006 vs sedentary, t = 4.12), correlation between the sum of the scale and the Mets (metabolic equivalent) evaluated by IPAQ with r = 0.073 and p = 0.048. In Study II, 114 males, young, physically active and insufficiently active adults, offspring of normotensives or hypertensives, overweight or eutrophic were selected. The IPAQ was used for the level of physical activity, the PSS-10 for perceived stress, the WHOQOL for quality of life analysis. Anthropometric, hematological and biochemical analyzes and systemic oxidative stress evaluations were performed. In addition, blood pressure (BP) recording beat-to-beat using the Finometer?? was used for evaluation of hemodynamic parameters and of heart rate (HRV) and BP variability (BPV). The results showed a higher BMI and % of fat, both by folds and Bioelectrical impedance analysis, in the overweight groups compared to the eutrophic groups, as well as higher weekly caloric expenditure among the active groups in relation to the sedentary groups, independently of the familial history of hypertension (FHH). In the hematological and biochemical profile all groups presented values within the normal range. The BP values were similar between the studied groups, but a lower heart rate was observed in the active groups with a negative FHH. There was no difference in perceived stress levels, but the quality of life was better in the active groups, with lower benefits in the group with a positive FHH. In relation to HRV, the active eutrophic groups, both with a positive and negative FHH, had higher values of RMSSD (cardiac parasympathetic modulation) and lower sympatho/vagal balance in relation to their respective eutrophic sedentary groups, which was not observed in overweight groups. The groups with a positive FHH presented higher values of both simpato/vagal balance (eutrophic and overweight), SAP variance (just overweight) and vascular sympathetic modulation (LF) (eutrophic and overweight) compared to the group with negative FHH, and these differences were attenuated in the physically active group with FHH and overweight. The active eutrophic group with a negative FHH presented better baroreflex sensitivity in relation to their respective sedentary group, which was not observed in the group with a FHH. With regard to oxidative stress, active groups with a negative FHH had lower levels of hydrogen peroxide and nitrites and greater activity of the antioxidant enzyme glutathione peroxidase (just eutrophic) when compared to their respective sedentary groups, which was not observed for the offspring of hypertensives (sedentary vs actives). In addition, these two parameters and the oxidation of proteins (carbonyls) were increased in the overweight and non-overweight groups with a FHH in relation to the eutrophic group with a negative FHH, being attenuated in the active group with FHH and overweight. In conclusion, the scale of adherence to the physical active developed in this study showed good reproducibility, good internal consistency, clarity and discriminating validity. In addition, our results showed that even under normal clinical conditions, a positive FHH, regardless of the presence of overweight, induced autonomic dysfunction and increases in oxidative stress markers that may be precursors of cardiometabolic diseases in this genetically predisposed population. On the other hand, a physically active lifestyle improves HRV, baroreflex and parameters related to redox status in individuals with a negative FHH. Such benefits seem to be attenuated by the positive FHH, but a physically active lifestyle seems to prevent/attenuate the dysfunctions observed in this condition. |
