    Abstract The pandemic of the new coronavirus (COVID-19) may be affecting the physical activity (PA) level in much of the population. This study aimed to investigate the prevalence of physical inactivity and sedentary behavior (SB) among adults with chronic diseases and their associations with sociodemographic factors during the COVID-19 pandemic. This cross-sectional study included 249 participants (age: 18–91 years; 61.4% female) with chronic conditions and attended the Family Health Strategy program in a small town in Brazil. Data were collected between 2020-07–13 and 2020-07-24 by face-to-face interviews. Self-reported PA, sitting time, chronic diseases, medication use, sociodemographic data, and self-isolation adherence were obtained by questionnaire. During this specific time point of the COVID-19 pandemic, 71.5% of participants did not meet the PA recommendations (≥500 METs-min/week), and the prevalence of SB risk (≥4 h sitting) was 62.7%. Adjusted logistic regression indicated that male participants (odds ratio [OR]: 1.89 [95% CI 1.02–3.53]), living alone (OR: 2.92 [95% CI 1.03–8.30]) or in a two-person household (OR: 2.32 [95% CI 1.16–4.63]), and those who reported sometimes performing self-isolation (OR: 3.07 [95% CI 1.47–6.40]) were more likely to meet the minimum PA recommendations. Current smokers had a lower odds (OR: 0.36 [95% CI 0.14–0.95]) of meeting the PA recommendations. Older participants (OR: 2.18 [95% CI 1.06–4.50]) and those who had multimorbidity (OR: 1.92 [95% CI 1.07–3.44]) were more likely to have a higher degree of SB. There is an urgent need to mitigate physical inactivity and SB, and public health interventions must take into account sociodemographic status.

    Abstract Objetivo: O objetivo do estudo foi analisar a associação entre equilí­brio dinâmico e idade e massa corporal em crianças. Materiais e Métodos: Nesta pesquisa primária, quantitativa e de corte transversal, participaram 40 crianças de ambos os gêneros, sendo 20 do gênero masculino e 20 do gênero feminino. Para análise da massa corporal, utilizou-se uma balança antropométrica mecânica da marca Filizola®, com capacidade para 150 kg. Para análise do equilí­brio foi utilizado o teste de equilí­brio dinâmico de Johnson e Nelson. Resultados: Os resultados demonstram que o equilí­brio dinâmico apresenta correlação com idade (r=0,336; p=0,034*), porém não apresenta relação com massa corporal (r=-0,019; p=0,455). Conclusão: Por fim, conclui-se que há uma associação do equilí­brio dinâmico com a idade. As sugestões para estudos futuros são associações de outras habilidades fí­sicas com a idade e massas corporal.

    Abstract The aim of this study was to investigate the effect of post-activation potentiation (PAP), carbohydrate (CHO) mouth rinse, and the combination of both strategies on repeated sprint ability (RSA). Twenty male soccer players (age = 18.9 ± 0.9 years, body mass = 71.8 ± 5.2 kg, height = 178.2 ± 6.3 cm) randomly performed four experimental conditions before RSA test (six sets of 40 m): (I) placebo (PLA) control, (II) CHO mouth rinse (6% maltodextrin), (III) PAP + PLA, and (IV) PAP + CHO. The PAP protocol involved two sets of five repetitions (80% 1RM) of the back squat exercise. A one-way repeated measures analysis of variance followed by Bonferroni post hoc test was used to compare the experimental conditions. Results indicated that PAP + CHO and PAP + PLA had better results for the variables best sprint time, mean sprint time, and total sprint time compared with CHO and PLA (p < 0.001; small effect size). No significant interaction between the experimental conditions was observed for the variable RSA performance decrement, and no significant difference between conditions, i.e., PAP + CHO vs. PAP + PLA and CHO vs. PLA control was found. In conclusion, PAP positively affects RSA performance in soccer players; however, the combination of PAP and CHO mouth rinse showed no additional effect.
