Efeito da dança em ambiente aquático na fibromialgia / Effect of dance in aquatic environment in fibromylgia

A fibromialgia é uma das doenças reumatológicas mais frequentes e com incidência maior na população feminina. A fisioterapia é um dos tratamentos mais procurados para minimizar os sintomas, e a terapia aquática tem apresentado melhores resultados". OBJETIVO: Avaliar a dor, qualidade de vida, fadiga, pressão arterial (PA) sistólica, diastólica e distância total percorrida de mulheres com fibromialgia (FM), antes e após terapia com dança do tipo jazz dance em ambiente aquático. MÉTODOS: Foi realizado um estudo longitudinal com amostra semiprobabilística após aprovação da comissão de ética da Universidade Presbiteriana Mackenzie, por meio da plataforma Brasil. Participaram 10 voluntárias, com idade entre 40 e 70 anos, submetidas a 22 sessões, 2 vezes por semana, com 20 minutos inicias de alongamento, 30 minutos de dança e 10 minutos finais de relaxamento. Para a coleta de dados foi utilizado o Questionário de impacto da Fibromialgia (QIF), Escala Borg (Fadiga), Teste de caminhada de 6 minutos (TC6) e escala análoga de dor (EVA). Os dados obtidos foram inicialmente submetidos ao teste de KS para a verificação da normalidade da amostra, em seguida analisados por testes estatísticos Wilcoxon e T-Student, com nível de significância p≤0.05. RESULTADOS: Houve diferença significativa importante quando comparado o EVA inicial com o EVA final, com p=0,000. Em relação ao QIF não houve diferença significativa quando comparado o inicial com o final, sendo p=0,241. Assim como no TC6 nas variáveis pressão arterial sistólica (p=0,780), pressão arterial diastólica (p=0,257), escala Borg (p=0,435) e distância total percorrida (p=0,765). CONCLUSÃO: A dança como exercício aeróbico em ambiente aquático proporcionou melhora na dor, não apresentando alteração significante nas outras variáveis.

Fibromyalgia is one of the most frequent rheumatological diseases and with a higher incidence in the female population. Physiotherapy in general is one of the treatments used to minimize symptoms and aquatic therapy has been showing better results". OBJECTIVE: To evaluate the pain level, life quality, fatigue, diastolic and systolic blood pressure, and total distance covered of women with fibromyalgic, before and after therapy with jazz dance in aquatic environment. METHOD: A longitudinal study with semiprobabilistic sample was carried out after approval by the Ethics Committee of Universidade Presbiteriana Mackenzie. There were 10 volunteers, aged between 40 and 70 years. They were submitted to 22 sessions, being it twice per week and contemplating 20 minutes of initial stretching, 30 minutes of dance and 10 minutes of relaxation. Data were collected through the use of scales: Fibromyalgia Impact Questionnaire (QIF), Borg Scale (Fatigue) and 6-Minute Walk Test (6MWT) that were applied at the beginning and end of the collections, and analog pain scale (EVA), which was applied at the beginning and at the end of each intervention. The data were initially submitted to the KS test to verify the normality of the sample, then analyzed by Wilcoxon and Student T tests, with significance level p ≤ 0.05 (5%). RESULTS: There was a significant difference when the initial EVA was related to the final EVA, with p = 0.000. Regarding QIF, there was no significant difference when comparing initial and the final EVA, with p = 0.241. Even as the TC6 in the variables systolic blood pressure (P = 0.780), diastolic blood pressure (p = 0.257), Borg scale (p = 0.435), and total distance covered (p = 0.765). CONCLUSION: Dance as an aerobic exercise in aquatic environment provided an improvement in pain.

Effects of exercises on the right ventricle of female micesubmitted to ovarian hormone deprivation

Introduction: Several studies indicate that the estrogen deficiency increase the incidence of the cardiovascular diseases in women in post-menopausal period and that the exercise program may prevent or relieve problems such as cardiovascular disease, obesity, muscle weakness, osteoporosis and depression. The effects of the estrogen deprivation in the myocardium still remain unclear, mainly in the right ventricle. The aim was to investigate the effects of exercises on the right myocardium in the female mice subjected to deprivation of ovarian hormones. Material and methods: A total of 15 female mice at 9 months of age, divided into 3 groups (n = 5) were studied: non-ovariectomized sedentary (S); ovariectomized sedentary (OS), ovariectomized trained (OT) animals. Ovariectomy was performed at 9 months of age and physical training began 7 days after surgery. The animals underwent a physical training protocol for 4 weeks on a treadmill with progressive speed and load (one hour a day/5 days a week at 50 to 65% of the maximum speed of running). After the experimental proceeding, the heart were removed and processed accordingly to conventional protocol for optical microscopy, and the slides stained by the methods of Hematoxylin and Eosin Stereology was used to analyze the components of the myocardium. Results: Ours results indicate that the exercise training promoted cardiomyocyte hypertrophy, increase in connective tissue with decreased cardiomyocytes. Conclusion: Our data suggest that moderate exercise promoted right ventricular remodeling with cardiomyocyte hypertrophy and increase in connective tissue, to fit the modifications promoted by exercise in the left ventricle.
