The new coronavirus (SARS‐CoV‐2) appearance in Wuhan, China, did rise the new virus disease (COVID‐19), which spread globally in a short time, leading the World Health Organization to declare a new global pandemic. To contain and mitigate the spread of SARS‐CoV‐2, specific public health procedures were implemented in virtually all countries, with a significant impact on society, making it difficult to keep the regular practice of physical activity. It is widely accepted that an active lifestyle contributes to the improvement of general health and preservation of cardiovascular, respiratory, osteo‐muscular and immune system capacities. The positive effects of regular physical activity on the immune system have emerged as a pivotal trigger of general health, underlying the beneficial effects of physical activity on multiple physiological systems. Accordingly, recent studies have already pointed out the negative impact of physical inactivity caused by the social isolation imposed by the public sanitary authorities due to COVID‐19. Nevertheless, there are still no current narrative reviews evaluating the real impact of COVID‐19 on active lifestyle or even discussing the possible beneficial effects of exercise‐promoted immune upgrade against the severity or progression of COVID‐19. Based on the consensus in the scientific literature, in this review, we discuss how an exercise adherence could adequately improve immune responses in times of the ‘COVID‐19 Era and beyond’.

Purpose: The aim of this study was to test the effects of chair-based exercise programs on salivary stress hormones, physical fitness, and functional autonomy of institutionalized older women. Method: In total, 47 participants (80 ± 8.04 years old) were recruited and allocated into three groups: chair-based aerobic exercises (CAE, n = 19), chair-based elastic-band strength exercises (CSE, n = 15), and a control group (CG, n = 13). A 14-week exercise intervention was done for the CAE and CSE groups, two times per week, in no consecutive days. Members of the CG did not participate in any type of exercise but kept their regular lifestyle. Fear of falling, autonomy, physical fitness, salivary cortisol, and alpha-amylase levels were assessed before and after the intervention. Results: The CAE group improved upper and lower body strength, agility–dynamic balance, and autonomy, with fear of falling decreasing significantly (p < .05, moderate effect size). Both exercise groups showed a trend toward an increase in salivary alpha-amylase levels (CAE = 43%, d = .31, and CSE = 44%, d = .41). Conclusion: Both exercise programs were able to improve functional autonomy, even in elders older than 80 years of age. It might be interesting to investigate the effectiveness of combining both aerobic and strength exercises in a unique protocol. The modulation effect of exercise in the hormonal responses needs to be further explored.

Resumo O presente estudo teve como objetivo analisar a magnitude do efeito estatístico das diferenças de média na avaliação do desempenho cognitivo em idosos-fragilizados. A pesquisa foi realizada nas bases de dados PubMed, B-on, Ebsco, Scielo, Eric, Lilacs e Sportdiscus. Foram incluídos estudos observacionais, coorte ou transversal, selecionados a partir do título, resumo e leitura do manuscrito. Os principais descritores utilizados foram: idoso, idoso-fragilizado, cognição, avaliação geriátrica e outros termos adicionais. De 1078 manuscritos identificados, 12 foram selecionados. Quando comparados os valores de média do desempenho cognitivo dos pré-fragilizados (n = 11265) e fragilizados (n = 2460) foram encontradas diferenças significantes (p < 0,001), com valores mais baixos emergindo no grupo dos idosos-fragilizados. Os resultados demostraram que o baixo desempenho cognitivo está relacionado à condição de idoso-fragilizado, sendo um desfecho clínico provável em idosos. Nestas circunstâncias, qualquer estratégia que vise atenuar ou reverter a incidência desta condição deve ter em consideração que durante o processo de envelhecimento, a fragilidade física e a cognitiva parecem ter trajetórias temporais similares.

The aim of this study was to analyze the effects of treatment by hydrotherapy on quality of life, perception of pain and the severity of depression in a group of patients with fibromyalgia. We evaluated 64 females divided into two groups: hydrocinesiotherapy (n = 33, 58.2 ± 10.6 years) and control group (n = 31 with 59.6 ± 9.4 years) with clinical diagnosis of fibromyalgia. Individuals were assessed by Visual Analog Scale of Pain (VAS), the Fibromyalgia Impact Questionnaire (FIQ) and the Beck Depression Inventory. Participants underwent a treatment in a hydrotherapy pool heated to 33ºC over a period of 15 weeks, two sessions per week of 45 minutes, a total of 30 sessions. The exercises were underwater: cardiovascular conditioning, strength training, mobility, coordination, balance and still, stretching exercises and muscle relaxation. The ANOVA 2 × 2 and Kruskall-Wallis was used for statistical analysis There were statistically significant improvements in the perception of pain intensity (Δ% = -28.2%, p < 0, 01), quality of life (Δ% = -32.4%, p < 0, 05) and depression symptoms (Δ% = -35.4%, p < 0, 05) in favor of the Hydrotherapy group compared to the control group. The study suggests that hydrocinesiotherapy was effective as an alternative therapy for fibromyalgia, however further studies are recommended to test the associations between the variables and intervention programs and using the water activities, and the modifiability of the parameters of physical and mental health when these individuals undergo programs of short, medium and long duration.
