Objective: to investigate the association between body mass index (BMI) and functional fitness levels linked to the Elderly in Movement Program of the city of Curitiba, in the state of Paraná, Brazil. Methods: The study is characterized as correlational and crosssectional. The sample consisted of 1,806 elderly female participants of the Elderly in Movement Program. The short version of the IPAQ was used to evaluate participation in physical activities; body weight (kg) and height (m) were measured to calculate BMI (kg/m²), while the motor tests proposed in the Senior Fitness Test were used to evaluate the functional fitness of the elderly women. Descriptive statistics, the chi-squared test and binary logistic regression were used for data analysis. Results: The results showed that 24.0% of the sample exhibited eutrophic nutritional status, 42.9% were overweight and 33.1% were obese. The elderly women classified as overweight and obese had lower functional fitness scores, based on the rating of Rikli and Jones, while the elderly women classified as eutrophic exhibited levels within the normal range. Obese elderly women were more likely to have low scores in the following functional fitness tests: Walk for 6 minutes, Chair Stand, Chair Sit and Reach, Back Scratch and 8-Foot Up and Go. Conclusion: The study indicated an association between, BMI and functional fitness in the elderly women participating in the program, where the majority of elderly women classified as obese exhibited low fitness in all tests.
Accurate predictive tools are key factors for cancer care. Phase angle (PhA) has been proposed as a marker of cellular health, particularly of cell-membrane integrity. Cutoff values have been proposed, including for cancer survivors. This study aimed to assess the usefulness of the proposed PhA cutoff, as a marker of bioelectrical impedance analysis (BIA) assessed health-status, and functional capacity in breast cancer (BC) survivors. This cross-sectional study included 25 women (50.6 ± 8.6 yrs) survivors of BC, divided into two groups according to the PhA reference value of 5.6 et al. 2008). BIA-assessed health status parameters included: extracellular water (ECW), intracellular water (ICW), total body water (TBW), PhA, body mass, fat-free mass, muscle mass, body cell mass (BCM). Four functional tests were performed: 30 s chair-stand test, timed up and go test, ball throw test and 6-minute walking test. Results showed G2 had lower ECW/ICW ratio (p=0.001; ES=1.2), ECW/BCM ratio (p=0.001; ES=3.2) and ECW/TBW ratio (p=0.001; ES=4.8). There was no difference in functional capacity between groups. The results of the present study show that patients with higher PhA values have a higher ICW values and preservation in the ECW/ICW ratio, suggesting it's a better cell membrane quality and integrity. Relation of both PhA and cell membrane integrity with functional capacity warrants further research.
Resumo Introdução O processo de envelhecimento ocasiona redução da função física podendo o indivíduo ter uma diminuição na percepção da qualidade de vida. Sendo assim, realizar atividade física regular pode ser um fator favorável a uma melhor percepção de qualidade de vida. Objetivo comparar a percepção da qualidade de vida em idosas praticantes e não praticantes do método Pilates. Método as idosas foram separadas em grupo Pilates (n = 60), ginástica (n = 63) e não praticantes de atividades físicas regulares (n = 62) e pelas faixas etárias de 60 a 64,9 anos e 70 a 74,9 anos. A percepção da qualidade de vida foi estimada pelo questionário WHOQOL-OLD e WHOQOL-BREF. A distribuição dos dados foi verificada com o teste de Shapiro-Wilk, além disso, foi utilizado o teste de Kruskal-Wallis com post hoc de Mann-Whitney e correção de Bonferroni. Resultados para a faixa etária de 60 a 64,9 anos avaliada pelo questionário WHOQOL-OLD, as idosas que não praticavam atividade física regular apresentaram uma melhor percepção no domínio de participação social do que o grupo da ginástica. Para a faixa etária de 70 a 74,9 anos, avaliada pelo mesmo questionário, o grupo de Pilates apresentou melhores percepções na maioria dos domínios de qualidade de vida. Conclusão o grupo das idosas praticantes do Método Pilates apresentou os maiores escores na maioria dos domínios de qualidade de vida para a faixa etária de 70 a 74,9 anos.
