RESUMO
The objective of this study was to observe the home-confinement effects on physical fitness, physical activity (PA), and body composition in active older adults, and to compare physical fitness and PA according to quality of life (QoL) during confinement. A total of 72 physically active older adults (61.1% females; 74.24 ± 5.57 years) were assessed pre- and postconfinement for aerobic capacity (6-min walk test), lower (30-s sit-to-stand), and upper (30-s arm-curl) body strength, PA (short-version of the International Physical Activity Questionnaire), and QoL (EQ-5D-visual analogue scale). The pre- and postconfinement comparisons show declines in upper (-2.24 ± 0.45 repetitions; p < .001; η2 = .276) and lower body strength (-2.65 ± 0.42 repetitions; p < .001; η2 = .378) in both genders, but not in aerobic capacity. Ninety percentage of older adults perceived a decline in PA. Older adults reporting high QoL increased 19.27 ± 97.04 m in the 6-min walk test, while the participants with low QoL reduced 28.32 ± 63.27 m (p = .018; η2 = .090). Previously active older adults did not have their aerobic capacity decrease significantly despite a decline in upper and lower body strength during an 11-week home confinement period.

This study examined the mediating effect of walking on the relationship of social support with vitality and psychological distress. Data from a sample of 2,859 older adults were used. The older adults completed the 36-Item Short-Form Health Survey vitality scale, the Global Health Questionnaire, the International Physical Activity Questionnaire, and a social support attributes questionnaire. All social support variables were positively associated with vitality and negatively associated with psychological distress. Walking mediated the associations of appreciation for (3%) and frequency of (8%) social contacts, participation in group activities (19%), closeness from family and friends (8%), and concern from people around (6%) with vitality. Walking also mediated 33% of the association between participation in group activities and psychological distress. The main findings of this study suggest that participation in group activities, as part of social support, in later life is beneficial to improve older adults' vitality and reduces psychological distress, with walking being a strong mediator of these relationships.

INTRODUCTION: The COVID-19 pandemic led to the implementation of physical-social distancing measures-including self-isolation, home confinement, and quarantine around the world, with psychological consequences such as depression. Older adults are especially likely to develop depressive symptomatology. This study aims to investigate the association between physical activity intensities and sedentary behavior with depression levels among previously active older adults during the COVID-19 lockdown. METHODS: A total of 1,123 physically active older Brazilian adults (67.68 ± 5.91 years, 91.00% female) were interviewed by telephone in regard to sociodemographic, general health status, depression (GDS-15), and physical activity (IPAQ-SV) after being home-confined for 11.59 ± 2.42 weeks. Participants were also asked to self-report changes in their physical activity levels and time spent sitting. Descriptive statistics (mean, frequencies), between-groups comparisons (t-tests and chi-square), and hierarchical regression analysis were used. RESULTS: About 83.80% of older adults self-reported a decrease in daily physical activity levels and 73.90% increased sitting time. Overall, depressive symptoms were observed in 30.40, and 20.80% met physical activity recommendations. Daily moderate (ß = -0.174; 95% CI = -0.026; -0.012) and moderate-to-vigorous (ß = -0.183; 95% CI = -0.023; 0.011) physical activity intensities were negatively associated with depression score explaining 2.6 and 2.9% of depression variability, respectively, after adjusting for age, gender, education level, body mass index, and polypharmacy. Daily walking and sitting time were not associated with the depression score (p > 0.05). CONCLUSION: The results provide empiric suggestion supporting moderate to vigorous physical activity as a way to reduce depressive levels among older adults during COVID-19 confinement. Supervised home-based exercise programs, specifically designed for older adults, might be an important strategy to maintain and improve older adults' mental health.
RESUMO
The aim of this study was to investigate alterations in physical fitness and anthropometric parameters as well as depression symptoms among the elderly after participation in the "National Walking Program" (Portugal). The sample consisted of 26 elderly people over six months with a total of 72 exercise sessions. The exercise sessions consisted of aerobics (walking and running) and strength and flexibility exercises. Participants were assessed pre- and post-intervention for physical fitness with the Rikli & Jones test. The anthropometric measurements were assessed with a bioimpedance scale and a stadiometer, and depression with Yesavage's Geriatric Depression Scale. Physical activity was only assessed with an accelerometer at the pre-intervention phase. For statistical analysis, the student t test for paired samples was performed using SPSS 21 software. Statistically significant improvements were found in depressive symptoms (p ≤ 0.001), and in all physical fitness tests (p ≤ 0.05) except for flexibility tests (p ≥ 0.05). Waist circumference reduction also showed the positive effects of the intervention (p = 0.031). The conclusion drawn is that participation in the "National Walking Program" for 6 months was effective in improving the physical and psychological health of the elderly.

O objetivo do presente estudo foi verificar as alterações nos idosos após a participação no Programa Nacional de Marcha e Corrida de Portugal, em relação ao nível de aptidão física, medidas antropométricas, bem como os sintomas depressivos. Fizeram parte da amostra 26 idosos por um período de 6 meses com total de 72 aulas, que foram conduzidas com exercícios aeróbicos (marcha e corrida), de força e flexibilidade. Os dados de aptidão física foram mensurados pelo teste de Rikli & Jones, os dados antropométricos através de balança de bioimpedância/estadiômetro e a depressão pela Escala de Depressão Geriatria de Yesavage, estas informações foram coletadas pré e pós-intervenção. O nível de atividade física foi avaliado por acelerômetro apenas na pré-intervenção. Para as análises estatísticas foi utilizado o programa SPSS através do teste t-Student para amostras pareadas. Encontramos uma melhora significativa no pré para o pós-teste nos sintomas depressivos (p ≤ 0.001) e em todos os testes de aptidão física (p ≤ 0.05), com exceção dos de flexibilidade (p ≥ 0.05). A redução da circunferência da cintura também demonstrou os efeitos positivos da intervenção (p = 0.031). Podemos concluir que a participação no programa de Marcha e Corrida durante 6 meses foi eficaz na melhora da saúde física e psicológica do idoso.
