Modelos matemáticos para estimativa do consumo máximo de oxigênio pela ventilometria de esforço em indivíduos saudáveis

The relation between metabolic demand and maximal oxygen consumption during exercise have been investigated in different areas of knowledge. In the health field, the determination of maximal oxygen consumption (VO2max) is considered a method to classify the level of physical fitness or the risk of cardiocirculatory diseases. The accuracy to obtain data provides a better evaluation of functional responses and allows a reduction in the error margin at the moment of risk classification, as well as, at the moment of determination of aerobic exercise work load. In Brasil, the use of respirometry associated to ergometric test became an opition in the cardiorespiratory evaluation. This equipment allows predictions concerning the oxyredutase process, making it possible to identify physiological responses to physical effort as the respiratory threshold. This thesis focused in the development of mathematical models developed by multiple regression validated by the stepwise method, aiming to predict the VO2max based on respiratory responses to physical effort. The sample was composed of a ramdom sample of 181 healthy individuals, men and women, that were randomized to two groups: regression group and cross validation group (GV). The voluntiars were submitted to a incremental treadmill test; objetiving to determinate of the second respiratory threshold (LVII) and the Peak VO2max. Using the método forward addition method 11 models of VO2max prediction in trendmill were developded. No significative differences were found between the VO2max meansured and the predicted by models when they were compared using ANOVA One-Way and the Post Hoc test of Turkey. We concluded that the developed mathematical models allow a prediction of the VO2max of healthy young individuals based on the LVII

Apitidão funcional e comportamentos relacionados à saúde em mulheres idosas do município de Jequié-BA

The identification of the factors that interfere in the decline of functional conditions is useful in the planning of actions addressing the improvement in the conditions of the lives of elderly people. The purpose of this investigation was to analyze the relationship between social demographics and health aspects of the functional condition in elderly women of low income of the Brazilian northeast. This crosssectional study involved a representative sample of 222 women with an average age of 70 years (± 7.1), belonging to coexisting groups and that were resident in the urban area of the municipal district of Jequié /Bahia. In order to achieve this objective, a battery of physical tests of functional aptitude was carried out previously tested in pilot study, anthropometric measurements collected with a comparison of the measures referred to the reported weight and height as well as the application of an interview with questions containing subjects related to social demographic variables, clinical conditions and health, physical conditions and behaviors. Descriptive statistics Proceedings (frequency, average, standard deviation and percent distribution) were used for statistic analysis, and the calculation of the respective odds ratio by binary logistics regression, for the analysis of factors hierarchically grouped; p<0.05. The prevalence of 56% (n=122) of women considered with moderated or serious type of functional limitations was found, In which from multi-varied hierarchical analysis, significant association was verified with the age group over 80 years (p=0.02), conditions of widowhood (p=0.04), presence of arterial hypertension (p=0.001), and physical inactivity during leisure time (p=0.03). On the other hand for functional incapacities the prevalence was of 46.8% (n=104) being associated to the increase of the age (p=0.01), hospitalization (p=0.02), absence of physical activities along their lives (p=0.001) and the occurrence of alterations in the cognitive function (p=0.001). The normative table for the parameters of physical fitness generated conducive to health professionals in the diagnosis of health conditions and the prescription of physical exercises. The identified characteristics that are associated with the functional limitations / functional incapacities suggest a complex causal net in the determination of the functional condition in elderly women. However, actions addressed to the incentive of the practice of physical activities in the leisure time and the preservation of the cognitive function can contribute to a life with more quality for these people. This research was multidisciplinary approach to involve elements of psychology, nutrition and Physical Education in the elucidation of the object of study related to the functional condition of elderly women

Marcas dermatoglíficas, Antropometria e as qualidades físicas básicas dos escolares da rede municipal da cidade de Manaus

The objective of this study of comparative descriptive character went aimed at to analyze the characteristics dermatoglyphics, anthropometrics and the basic physical qualities, in 180 selected scholars in a stratified way, distributed like this: 10 year-old boys = 32; 09 years = 32; 08 years = 32; 10 year-old girls = 28; 09 years = 28; 08 years = 28), studying the fundamental teaching of the School Good Municipal Hope, located in the area east, in the Neighborhood of the Crowned, in the city of Manaus, Amazon. For identification of the dermatoglyphics characteristics collected, was the fingerprints; for evaluation of the corporal mass, height and IMC, they were used a digital scale with an estadiometer of the mark Filizola. The tests: to sit down and to reach flexibility); Horizontal Impulse or I jump in distance stopped (force of inferior members); Flex and extension of the trunk (it Forces abdominal); Flexion and extension of the arms in suspension in the bar (Force of superior members); 30 meters (Speed) and 9 minutes (Resistance applied aerobic) was to evaluate the basic physical qualities. The results demonstrated that differences didn't exist among the goods, in most of the studied variables, and the existent differences among the ages of 8, 9 and 10 years, they demonstrate a normality tendency in the infantile development

Marcadores genéticos, antropometria e qualidades físicas básicas nos estágios maturacionais de nadadores paraibanos

The aim of this research was to analyse genetic markers, anthropometry and basic physical qualities in the differret stages of sexual maturation in swimmers in Paraíba. It is characterised as a descriptive cross sectional study. The sample was composed of 119 swimmers (males) that were divided among the stages of sexual maturation, from 7 to 17,9 years of age. They were associated to a local federation, the Confederação Brasileira de Desportes Aquáticos. The tests used were: genetic markers dermatoglyphics; Anthropometry body mass, stature, arm span, fat percentage and somatotype; physical qualities speed tests (25 meters crawl), strength (vertical jump) to inferior limbs, verarm throwing arremesso of a 2kg medicineball to superior limbs and abdominal), resistence (12 minutes to swimming), agility (he multistage 20-meter shuttle run test), flexibility (sit and reach test ) and coodination (stroke index); power of swimming (mean velocity in 25 meters mutiplied by body mass) and the self assessment of the sexual maturation supervised by a pediatric specialist. In the analyses we used the test normality of Shapiro-Wilk, then, we used ANOVA- one way followed by Post-Hoc test of Scheffé. The data showed in dermatogliphics a genetic tendence to velocity (L>W) with a predominance of the meso-ectomorphic somatotype profile; in relation to the physical qualities there was an evolution of the results in every stage due to the antropometric variables, except in the coordination tests. There were no significative differences between the stages. We conclude that swimming in Paraíba is composed of a signicative number of velocists with a mesomorph somatotype profile and low fat percentage, and that made it posssible to us to recomend that the trainings must be individual and according to personal characteristics of each athlete, and that the used variables must be specific for every region of the country. This dissertation presents a relation of multidiciplinar interface and its content has an application in Physical Education and Medicine

Força muscular respiratória e capacidade funcional em idosas hipertensas com sonolência diurna excessiva

The restriction of physical fitness is directly related with hypertension and sleep disorders, while the respiratory muscle strength is associated with hypertension, but the literature is scarce regarding its relationship with sleep disorders and particularly with excessive daytime sleepiness. Objectives: To compare physical fitness and strength of respiratory muscles between people with hypertension with excessive daytime sleepiness (EDS) and non EDS people, those who do not feel excessive daytime sleepiness, in addition to relate aerobics resistance and functional mobility of patients. Methods: An observational, analytical and transversal study, evaluated 32 elderly with hypertension, divided into two groups (EDS and non EDS), in which the following topics were measured; respiratory muscular strength, functional fitness, level of physical activity, level of excessive daytime sleepiness, quality of sleep and intensity of the patients snoring. Results: There was a significant difference in the level of EDS (P=0,00) and quality of sleep (p=0,03), however, the data related to snoring intensity (p=0,18), maximum inspiratory pressure PImax (p=0,39) and maximum expiratory pressure PEmax (p=0,98) did not show any difference. Also, no significant difference was observed concerning physical fitness, presenting p=0,08 for the sitting and getting up test on the chair in 30 ; p=0,54 for the extension and flexing of the elbow test in 30 ; p=0,38 for the walking test 6 ; p=0,38 for the parking gear test 2 , p=0,08 for the sitting and reaching test; p=0,42 for the scratching the back test; p=0,49 for the getting up and walking test; and p=0,62 for the global rate of activity limitation. There was moderate positive correlation between 6MWT and 2MST, r=0,54 (p=0,01) and negative moderate correlation between 6MWT and TUG, r=-0,61 (p=0,000) and between 2MST and TUG, r=-0,60 (p=0,000). Conclusion: The presence of EDS in the hypertension people studied, showed a bad quality of sleep, however this sleepiness did not influence the strength of the respiratory muscles. The physical fitness came out diminished in all hypertension people, regardless of the presence or non presence of sleep disturbance; and there is a close relationship between cardiovascular resistance and physical mobility, since when there is less cardiovascular resistance, there is precarious physical mobility and vice-versa

Avaliação da capacidade de caminhar do portador de obesidade mórbida utilizando teste de caminhada de 6 minutos

Introduction: The ability to walk is impaired in obese by anthropometric factors (BMI and height), musculoskeletal pain and level of inactivity. Little is known about the influence of body adiposity and the acute response of the cardiovascular system during whole the 6-minute walk test (6mWT). Objective: To evaluate the effect of anthropometric measures (BMI and WHR waist-to-hip ratio), the effort heart and inactivity in ability to walk the morbidly obese. Materials and Methods: a total 36 morbidly obese (36.23 + 11.82 years old, BMI 49.16 kg/m2) were recruited from outpatient department of treatment of obesity and bariatric surgery in University Hospital Onofre Lopes and anthropometric measurements of obesity (BMI and WHR), pulmonary function, pattern habitual physical activity (Baecke Questionnaire) and walking capacity (6mWT). The patient was checking to measure: heart rate (HR), breathing frequency (BF), peripheral oxygen saturation, level of perceived exertion, systemic arterial pressure and duplo-produto (DP), moreover the average speed development and total distance walking. The data were analysed between gender and pattern of body adiposity, measuring the behavior minute by minute of walking. The Pearson and Spearmam correlation coefficients were calculated, and stepwise multiple Regression examined the predictors of walking capacity. All analyses were performed en software Statistic 6.0. Results: 20 obese patients had abdominal adiposity (WHR = 1.01), waist circumference was 135.8 cm in women (25) and 139.8 cm in men (10). Walked to the end of 6mWT 412.43 m, with no differences between gender and adiposity. The total distance walked by obesity alone was explained by BMI (45%), HR in the sixth minute (43%), the Baecke (24%) and fatigue (-23%). 88.6% of obese (31) performed the test above 60% of maximal HR, while the peak HR achieved at 5-minute of 6mWT. Systemic arterial pressure and DP rised after walking, but with no differences between gender and adiposity. Conclusion: The walk of obese didn´t suffers influence of gender or the pattern of body adiposity. The final distance walked is attributed to excess body weight, stress heart, the feeling of effort required by physical activity and level of sedentary to obese. With a minute of walking, the obeses achieved a range of intensity cardiovascular trainning
