Item Avaliação da inicialização da marcha na gestante de baixo risco nos três trimestres gestacionais(Universidade Federal de Goiás, 2012-02-17) ANDRADE, Sara Rosa de Sousa; VIEIRA, Marcus Fraga; http://lattes.cnpq.br/4153462617460766; AMARAL, Waldemar Naves do; http://lattes.cnpq.br/4092560599116579Introduction: The pregnant woman's body promotes many changes, including their biomechanics. The hormonal action which increases the laxity causes structural changes in the static and dynamic skeleton. Other factors, such as weight gain, growth of the uterus and the breasts, will help changing the gravitational forces of the pregnant woman and cause large static and dynamic postural adjustments in pregnant women. The startup of gait position is the transition from quasi-static to the first step. It is a task that challenges the postural control, because the demands on the neuromuscular system are increased at the beginning of the march, since it is required a complex integration of neural mechanisms, muscle activity and biomechanical forces. Objective: describe the oscillation amplitude and mean velocity of center of pressure during startup of gait, to compare the behavior of the center of pressure between the three groups at different gestational periods, verify that the changes in the behavior of the center of pressure along the pregnancy is at risk dynamic stability for pregnant women. Methods: A total of oscillation amplitude and velocity of displacement of center of pressure during startup of gait in 57 low-risk pregnancies in three trimesters. Results: Significant differences were found when comparing the groups 1º trimester and 3º trimester for the variable amplitude of oscillation mediolateral and mediolateral displacement speed. Discussion: Pregnant women tend to decrease the amplitude of oscillation mediolateral and mediolateral displacement speed during gestation. Conclusions: The amplitude of oscillation anteroposterior and mediolateral displacement speeds and respective of the first quarter from the third there was, on average, a gradual decrease to a platform and to the platform 2. There were significant differences in the oscillation amplitude variables mediolateral and mediolateral displacement speed when comparing the groups 1° trimester and 3° trimester, being higher in 1º trimester for both variables. The variables analyzed showed minor differences and do not constitute an imminent risk to the dynamic stability of the pregnant woman.Item EFEITOS DO MÉTODO PILATES E DO TREINAMENTO COM PESOS NA MARCHA, NO PESO CORPORAL, NA CAPACIDADE FÍSICA FUNCIONAL E NA QUALIDADE DE VIDA DE MULHERES OBESAS(Universidade Federal de Goiás, 2008-09-29) CARNEIRO, Juliana Alves; VIEIRA, Marcus Fraga; http://lattes.cnpq.br/4153462617460766; SILVA, Maria Sebastiana; http://lattes.cnpq.br/1329422634395496The physical exercise is, currently, a means to intervene in the epidemics of obesity, helping with the weight loss, enhancing the capacity to perform daily activities and decrease the factors of risk of chronicle diseases. Objective: Assess the effectiveness of two programs of physical exercises (Pilates and weight training) and nutritional orientation, in the body weight, in the biomechanics gait, in the functional physical capacity and in the quality of life of obese women. Methodology: For twelve weeks, a group of fifteen obese women participated in a program of aerobic exercises and Pilates method and another group of fourteen obese women participated in a program of aerobic exercises and weight training. The groups participated of nutritional orientation. The exercise training lasted sixty minutes, three times a week. Were evaluated: the body weight, the body mass index (BMI), the six-minute walk test, the stand-up test, the sit-and-reach test, the SF-36(The Medical Outcomes Study 36 item) and the kinematics of the gait through recorded images and digitalized using specific software (Kwon 3D). Results: There was significant reduction of the body weight and the BMI, development in the rates of all tests of functional physical capacity and in the variables of the angular movement of the knee after twelve weeks of intervention in the two groups. The Pilates group showed significant improvement in five domains of SF-36, after twelve weeks and in the domain functional capacity between the two groups. The group trained with weights showed meaningful development in most of the space-time variables of the gait after twelve weeks. Conclusion: Both programs were effective to promote weight loss and enhance the functional physical capacity after twelve weeks. The Pilates method was more effective providing obese women with a better quality of life, mainly in the aspect of physical health. The weight training program was more effective to alter positively the kinematics variable which increased the dynamic stability of the gait of obese women after twelve weeks of intervention.
