O objetivo deste estudo foi avaliar as características músculo esqueléticase fisiológicas das bailarinas clássicas, e verificar se houve melhora destas características frente ao treinamento de quatorze semanas, aplicado com base no déficit físico-funcional de cada bailarina. Melhoras significativas foram observadas na capacidade aeróbica e nas amplitudes de movimentos de flexão, extensão e rotação externa dos quadris no grupo experimental no reteste. Não houve diferença significativa na força muscular, na flexibilidade músculo-esquelética geral e nas medidas antropométricas intragrupos e intergrupos no teste e reteste, enquanto a avaliação da composição corporal revelou uma diferença significativa dos percentuais de massa gorda e de massa magra entre os dois grupos no reteste. Os resultados encontrados sugerem que um treinamento complementar da aptidão física melhora a capacidade físico-funcional e a performance de bailarinas, o que pode contribuir na prevenção de lesões. The purpose of this study was to evaluate the physical and physiological characteristics of ten classical ballerinas, and verify if there was an improvement of these characteristics after a training period of fourteen weeks, which was based on the physical-functional deficits of each ballerina. Significant improvement was observed in aerobic capacity and joint range of motion for hip flexion, extension and externai rotation in the experimental group on the retest. There was no difference in the flexibility, in the muscular strength and in the anthropometric measurements both intragroup and intergroup on the test and retest, although body composition showed a difference in the fat content and in the percentage of the thin mass between the groups on the retest. The results suggest that a complementary training of the physical fitness improves the physical and functional capacities and the performance of the ballerinas, which may contribute in injury prevention.
OBJECTIVE: To evaluate the applicability of the London Chest Activity of Daily Living (LCADL) scale in patients on the waiting list for lung transplantation. METHODS: This was a cross-sectional study, conducted between May and September of 2010, involving 26 male and female patients on the waiting list for lung transplantation and treated at the Pulmonary Rehabilitation Program in the Complexo Hospitalar Santa Casa de Misericórdia de Porto Alegre, located in the city of Porto Alegre, Brazil. We evaluated the patients using the six-minute walk test (6MWT) and pulmonary function tests. We also obtained the LCADL scores, as well as the modified Borg scale scores for sensation of dyspnea and leg fatigue. Cronbach's alpha coefficient was used to determine the internal consistency of the LCADL scale. Linear regression analysis was used in order to identify associations between the total LCADL score (expressed as a percentage) and the variables studied. RESULTS: According to the LCADL scale results, 69% of the patients reported that the performance of their activities of daily living was significantly impaired by their dyspnea. The internal consistency of the LCADL scale was 0.89. After adjusting for age and FEV1, we found that the total LCADL scale score showed statistically significant negative associations with the six-minute walk distance (β = −0.087; p < 0.001) and the six-minute walk work (β = −0.285; p < 0.001). CONCLUSIONS: Our findings suggest that the LCADL scale is a useful tool for assessing patients on the waiting list for lung transplantation.
The objective of this study was to verify the possible association between Glutathione Stransferase genetic polymorphism and functional physical aspects in the elderly with and without type 2 diabetes mellitus (DM2), as well as the increased susceptibility to its development. To carry out this cross-sectional study, 5 mL of blood was collected from 45 elderly people. The polymorphism was detected by the multiplex polymerase chain reaction (GSTM1 and GSTT1 polymorphisms). Functional physical aspects were assessed using physical tests. For statistical analysis, the Shapiro-and Qui Square tests )²א( were used. The presence of the GSTM1 and GSTT1 genes were more prevalent. There was a significant association between GSTT1 null genotypes and the presence / absence of DM2. No association was found between genotypes and functional physical aspects. It is concluded that the nullity of the GSTT1 genotype is associated with the susceptibility of DM2, but without a statistically significant relationship with functional physical aspects.
