PurposeThe purpose of the present study was to identify the variability of blood pressure response to a 10-week resistance training (RT) program in hypertensive and normotensive elderly women.Participants and methodsTwenty-seven untrained hypertensive and 12 normotensive elderly women participated in the present study. A whole-body RT program was performed on two nonconsecutive days per week for 10 weeks. The responsiveness of resting systolic blood pressure (SBP) was determined based on the percent decline between the pre- and post-training time points T1 and T4. The term responders were used to describe subjects who exhibited a percent SBP decline ≥−2.58% and the term nonresponders for subjects who exhibited a percent SBP decline <−2.58%, respectively.ResultsBoth the responders and nonresponders in the hypertensive group presented significant changes in SBP (−7.83 ± 5.70 mmHg vs 3.78 ± 7.42 mmHg), respectively. Moreover, the responders and nonresponders in the normotensive group presented significant changes in SBP as well (−8.58 ± 5.52 mmHg vs 5.71 ± 3.84 mmHg).ConclusionSBP presents a heterogeneous response to a controlled RT program in hypertensive and normotensive elderly women. A different modality of training and additional therapies should be used for nonresponders in order to decrease resting SBP.

Objective:To compare the metabolic, anthropometric, arterial blood pressure, and muscle strength parameters of elderly women with and without metabolic syndrome.Methods:A case-control study with 27 (67.3±4.8 years of age, 31.0±5.0kg/m2) elderly women with metabolic syndrome and 33 (68.8±5.6 years of age, 27.2±5.3kg/m2) sedentary control elderly women. They were submitted to an evaluation of body composition by means of dual-energy X-ray absorptiometry and muscle strength testing with 10 maximal repetitions of knee extension.Results:When compared to the elderly women without metabolic syndrome, those with the metabolic syndrome had higher levels for body mass (72.2±13.5 versus 63.4±14.6kg, p=0.03), body mass index (31.0±5.0 versus 27.2±5.3kg/m2, p=0.007), fat mass (30.9±9.9 versus 24.4±8.5kg, p=0.01), systolic arterial pressure (125.1±8.2 versus 119.3±8.7mmHg, p=0.01), diastolic arterial pressure (75.5±6.9 versus 71.4±6.7mmHg, p=0.03), mean arterial pressure (92.5±6.2 versus 87.1±6.7mmHg, p=0.004), blood glucose (103.8±19.1 versus 91.1±5.9mg/dL, p=0.001), triglycerides (187.1±70.2 versus 116.3±36.7mg/dL, p=0.001), and creatine kinase (122.6±58.6 versus 89.8±32.5U/L, p=0.01); lower levels were found for fat-free mass (55.9±5.8 versus 59.3±6.7%; p=0.05), HDL-C (40.7±5.0 versus 50.5±10.1mg/dL, p=0.001), and relative muscle strength (0.53±0.14 versus 0.62±0.12, p=0.01).Conclusion:Elderly women with metabolic syndrome have a higher cardiovascular risk and less relative muscle strength when compared to those without metabolic syndrome. Relative muscle strength may be related to the cardiovascularr risk factors of the metabolic syndrome.

ObjectiveThe objective of this study was to apply the newly standardized definition for sarcopenia from the Foundation for the National Institutes of Health (FNIH) and the current definition for obesity to 1) determine the prevalence of sarcopenic obesity (SO) in obese elderly women; 2) compare the muscle strength, lean body mass, and markers of inflammation between obese elderly women with SO and nonsarcopenic obesity (NSO), and 3) elucidate the relationship between appendicular lean mass adjusted for body mass index (aLM/BMI) with muscle strength, lean body mass, and obesity indices.MethodsA total of 64 elderly obese women (age: 68.35±6.04 years) underwent body composition analysis by dual-energy X-ray absorptiometry. Participants were classified into two groups according to the definition of SO and NSO. Blood samples were collected for total cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, uric acid, urea, interleukin-6 (IL-6), glucose, and creatine kinase (CK) measurements.ResultsThe SO group presented a significantly greater BMI, fat (%), glucose, a marginal trend toward significance for uric acid, and IL-6 compared to the NSO group. In addition, the SO group displayed lower values for muscle strength and lean body mass. From a correlation standpoint, a higher aLM/BMI was positively associated with lean body mass and muscle strength and negatively associated with a lower BMI and percentage body fat.ConclusionThe definition criteria from FNIH and obesity permit the ability to illustrate the prevalence and identify SO in elderly women with low muscle mass, low muscle strength, and impaired markers of inflammation.

Resumo-A hipercifose torácica é uma das alterações posturais mais comuns, sendo definida como um aumento da curvatura torácica no plano sagital da coluna vertebral. Com o envelhecimento, ocorrem alterações no sistema de controle postural que influenciam a mobilidade funcional e o déficit de equilíbrio em idosos. O objetivo do estudo foi comparar a cifose torácica de idosos praticantes de atividade física com idosos sedentários, determinando, assim, a influência da atividade física na cifose dorsal do idoso. Através de um estudo transversal, avaliaram-se 40 voluntários de ambos os sexos e sadios, que foram divididos em dois grupos, um de praticantes de atividades físicas (G1) e outro de sedentários (G2) com idade a partir de 60 anos e inferior a 69, que foram alocados aleatoriamente para aplicação do método flexicurva. Para a análise foram utilizados estatística descritiva, com média e desvio padrão, e o teste t independente de Student. Verificou-se que os indivíduos praticantes de atividade física foram os que menos sofreram com as alterações da curvatura da cifose torácica, mas não houve diferença significativa entre os grupos, indicando que idosos ativos e sedentários possuem características similares quanto à cifose torácica. Podese concluir que idosos ativos e sedentários apresentam características similares quanto à cifose torácica.
