The aim of this study was to compare the physical fitness and cardiac autonomic activity among women with moderate and severe fibromyalgia (FM) and healthy women. This study included 35 women with FM (age: 46.2±8.9 years) and 17 healthy women (age: 44.3±9.9 years). Participants with FM were divided into moderate FM (n=15) and severe FM (n=20) according to the total score obtained in FM impact questionnaire. The heart rate variability was monitored using a portable cardiac monitor with participants resting in supine position during 10 min. Thereafter, the participants performed the chair sit and reach test, the chair stand test, and the 6-min walk test to measure the lower-body flexibility, lower-body muscle strength, and cardiorespiratory fitness, respectively. The lower-body muscle strength and cardiorespiratory fitness were both reduced in moderate and severe FM compared to healthy women (p<0.01), with greater reduction in severe FM when compared to moderate FM (p<0.05). In addition, the parasympathetic indexes of heart rate variability were all similarly decreased in both moderate and severe FM, when compared to healthy women (p<0.05). The cardiac parasympathetic activity is similarly decreased in women with both moderate and severe FM in comparison to healthy women, despite a greater physical deconditioning in severe FM.

A sarcopenia constitui a redução da massa muscular esquelética associada à perda da força muscular e/ou redução do desempenho físico relacionada com o decorrer da idade. A hospitalização e suas consequências são fatores importantes no desenvolvimento ou avançados estágios da sarcopenia. O objetivo desta pesquisa foi determinar o índice de massa muscular esquelética, o desempenho físico e a força muscular e então identificar a sarcopenia de idosos hospitalizados. A amostra foi constituída de 27 participantes divididos em três grupos: grupo de estudo (GE) com idosos hospitalizados (n=10); grupo controle de adultos hospitalizados (GCA) (n=9) e; grupo controle de idosos de comunidade (GCI) (n=8). Foram coletados dados antropométricos, realizada avaliação da massa muscular esquelética, da força muscular (preensão palmar) e do desempenho físico (Timed Up and Go). As avaliações foram realizadas em dois momentos com diferença de cinco dias entre a primeira e segunda avaliação. As idosas do GE desenvolveram sarcopenia grave durante a hospitalização com valores finais de TUG 18,33s (p=0,069); FPP 6,33 kg (p=0,625); IMME 6,34 kg/m 2 (p=0,156). Os idosos do mesmo grupo apresentaram os seguintes valores: TUG 16,86s (p=0,656); FPP 21 kg (p=0,741); IMME 9,71 kg/m 2 (p=0,501). Durante o internamento, os idosos do GE mantiveram os valores de força muscular, desempenho físico e índice de massa muscular esquelética dentro dos valores de referências, em contrapartida as idosas do mesmo grupo, desenvolveram sarcopenia grave em cinco dias.

The purpose of this study was to investigate the effects of supervised moderate combined exercise training in patients with post-COVID in the physical and functional capacity. Forty-one patients completed 6-week combined moderate exercise training. In baseline and after intervention, patients were assessments of screening, including clinical data and anthropometrics performed functional tests, which consisted of handgrip strength test, chair sit and reach test, arm curl test, 30-sec sit to stand test, timed up and go, and six-minute walk test (6MWT). Primary outcomes were results of functional tests, and secondary outcomes were clinical data. Handgrip strength (p < 0.001), flexibility (p = 0.01), strength of upper (p = 0.01) and lower limbs (p < 0.001), gait speed (p < 0.001) and 6MWT (p < 0.001) improved after rehabilitation. Resting heart rate, systolic and diastolic blood pressure were lower after intervention (p = 0.01; p = 0.05; p = 0.03, respectively). No one difference was observed in persistent symptoms (p > 0.05). In conclusion, exercise training promoted great physical, functional and cardiovascular benefits for post-COVID patients.
