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.

Background Repeated measures analysis of covariance and three-way analysis of variance with repeated measures are common statistical methods. For a valid interpretation of blood pressure (BP) response to exercise, a variety of additional statistical methods must be implemented. Four additional statistical methods are presented: technical error of measurement (SEM), smallest real difference (SRD), magnitude-based inference and mixed effect modeling technique (MEM). The aim of this perspective article is to demonstrate how to apply already known statistical analyses regarding BP responsiveness in order to improve interpretation and achieve higher reliability for future studies in exercise science. Methods A total of 27 hypertensive older women (aged 68.37 ± 5.55 years) participated in the present study. A whole-body resistance training (RT) program was performed on two nonconsecutive days per week for 10 weeks. BP was monitored during the 10-week RT intervention and after 15 weeks of detraining. First, individuals were classified as high and low responders, then statistical methods to analyze data included the use of SEM, SRD, magnitude-based inference and MEM. Results When magnitude-based inference was used to classify responsiveness, most participants displayed a trivial response. Decrements in SBP between 1 and 10 mmHg were not clinically meaningful but fell within the measurement error of the SBP measurements. Baseline SBP and time of training predicted post-SBP response. Conclusion Changes over time and declines in SBP might not be a SRD and fell in the SEM. Moreover, SBP responsiveness was the result of inappropriate control of covariates such as period of training.

-The aim of the present study was to compare differences in heart rate (HR) response during and following exercise in obese older women with different percent body fat levels. Ninety older, obese women aged 60-87 years participated in the study, were categorized, and enrolled to one of two groups based on a lower percent body fat (LPBF ≤ 41.10 %) or higher percent body fat (HPBF > 41.10 %) as measured by dual-energy x-ray absorptiometry. The peak HR during exercise and in the first and second minutes of recovery period were compared between groups. The HPBF group presented a lower peak HR during exercise (p =.001) and an impaired HR recovery (p =.001) when compared to LPBF group. The present study demonstrated that older women who were in exceedingly obese level have an impaired heart rate response during exercise and in the recovery period, indicating possible autonomic dysfunction.Key words: Aging; Obesity; Heart rate.

<p class="ResumoAbstract">The heart rate variability (HRV) and surface electromyography (sEMG) are important tools in the evaluation of cardiac autonomic system and neuromuscular parameters, respectively. The aim of the study was to evaluate the behavior of HRV and sEMG of the vastus lateralis in two exercise protocols on a cycle ergometer at 60 and 80 rpm. Eight healthy men cyclists who have trained for at least two years were evaluated. Reduction was observed followed by stabilization of RMSSD and SDNN indices of HRV (p&lt;0.05) along with increases in the amplitude of the sEMG signal (p&lt;0.05) in both protocols. Significant correlations were observed between the responses of HRV and sEMG in the cadence of 60 rpm (RMSSD and sEMG: r = -0.42, p=0.03; SDNN and sEMG: r = -0.45, p=0.01) and 80 rpm (RMSSD and sEMG: r = -0.47, p=0.02; SDNN and sEMG: r = -0.49, p=0.01), yet no difference was observed for these variables between the two protocols. We concluded that the parasympathetic cardiac responses and sEMG are independent of cadences applied at the same power output.</p>

Introduction: It is known that physical exercise is beneficial and precipitates adjustments to the autonomic nervous system. However, the effect of exercise on cardiac autonomic modulation in children, despite its importance, is poorly investigated. Objective: To bring together current information about the effects of exercise on heart rate variability in healthy and obese children. Methods: The literature update was performed through a search for articles in the following databases; PubMed, PEDro, SciELO and Lilacs, using the descriptors "exercise" and "child" in conjunction with the descriptors "autonomic nervous system", "sympathetic nervous system", "parasympathetic nervous system" and also with no descriptor, but the key word of this study, "heart rate variability", from January 2005 to December 2012. Results: After removal of items that did not fit the subject of the study, a total of 9 articles were selected, 5 with healthy and 4 with obese

Purpose. The purpose was to investigate an adapted pre-exercise screening tool to evaluate musculoskeletal injury in elderly women before starting a resistance training (rT) program, and to verify whether the tool could detect subjects not eligible for rT research on the basis of the rT program injury rate. Methods. Overall, 74 subjects participated in an orthopaedic evaluation by a certified physical therapist. History was taken of injury, dysfunction and related musculoskeletal diseases, surgeries, fractures, and falls. A series of tests was applied to identify potential risks and injuries. Results. Owing to history of falls and fractures and poor mobility and performance in physical function tests, 14 patients were excluded. The most common deficits were: rotator cuff tendinopathy (n = 2), knee osteoarthritis (n = 3), both rotator cuff tendinopathy and knee osteoarthritis (n = 3), lumbar discopathy (n = 2), cervicalgia (n = 1), back pain sciatica (n = 1), rotator cuff injury (n = 1), wrist and knee pain (n = 1). The main joints affected were: knees (n = 7), shoulders (n = 6), lumbar spine (n = 5), thoracic spine (n = 1), and cervical spine (n = 2). Overall, 60 elderly women started the rT program, while 39 had an adherence of > 90%. Conclusions. The adapted tool was effective in recruiting subjects, who had a lower injury rate during rT. It helped to identify musculoskeletal dysfunction and improved safety and adherence outcomes in elderly women.

Contextualização: O Contrato Social Moderno durante e após a Pandemia da Covid-19 ainda é o marco político e jurídico para a compreensão da importância histórico-civilizacional do fenômeno constitucional, é dizer, do Constitucionalismo e da linearidade das suas transformações, estas caracterizadas, no presente estudo, por meio da transição do Estado-Constitucionalismo democrático ao Estado-Constitucionalismo da exceção, especialmente entre o período relativo aos anos de 2020 e início do ano de 2022. Objetivos: Discorrer, com base no pensamento de Paolo Prodi, acerca do Contrato Social Moderno durante e após a Pandemia; analisar a concepção de Constitucionalismo enquanto fenômeno histórico de limitação do poder; efetuar uma abordagem do Estado de Exceção permanente, terminologia empregada pelo filósofo Carl Schmitt, adotando como parâmetro de observação, que levará em consideração a trajetória do Constitucionalismo Democrático ao Constitucionalismo da Exceção, o arcabouço político e jurídico destinado ao enfrentamento dos efeitos da Pandemia causada pelo vírus SARS-CoV-2. Metodologia: Será utilizada uma metodologia de abordagem fenomenológico-hermenêutica, métodos de procedimento histórico e monográfico, juntamente com a técnica de pesquisa por documentação indireta. Resultado: Uma primeira conclusão, que sobrevêm deste trabalho, realizada na forma de questionamento, é a seguinte: o que resta do Contrato Social Moderno em face dos Decretos editados durante a Pandemia?
