    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 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.

    Abstract Exercícios multiarticulares (MULTI) e monoarticulares (MONO) são comumente utilizados na prescrição do treinamento de força (TF). O objetivo do presente estudo foi investigar os efeitos dos exercícios MULTI e MONO sobre a carga total levantada (CTL) e a resposta do lactato sanguíneo, em sujeitos treinados em força. Participaram do estudo dez homens (idade: 28,0 ± 5,0 anos, estatura: 179,1 ± 5,9 cm, massa corporal total: 82,3 ± 8,8 kg) com experiência em TF (5,1 ± 1,1 anos). De maneira aleatorizada e cruzada, as sessões de exercício MULTI (supino reto) e MONO (crucifixo com halteres) consistiram na realização de 4 séries de 10 repetições máximas, com 90 segundos de pausa entre as séries. A CTL de cada sessão foi calculada e. a coleta de sangue foi conduzida nos momentos: antes, imediatamente, 5 e 10 minutos após cada sessão, para posterior determinação da concentração de lactato sanguíneo. A CTL foi maior (p<0,001) no exercício MULTI (2620,0 ± 416,5 vs. 1308,0 ± 148,5 kg; d=4,20) em comparação ao exercício MONO. Foi observado aumento na concentração do lactato sanguíneo após a execução de ambas sessões. No entanto, a magnitude de aumento do lactato foi maior no MULTI (6,3±1,2 vs. 3,5±0,5 mMol.L-1; d=3,05) em comparação ao MONO (p<0,001). Em conclusão, o protocolo MULTI propicia maior CTL e induz maior resposta do lactato sanguíneo em comparação ao protocolo MONO em homens treinados.

    Abstract ABSTRACT Objective Obesity can cause systemic arterial hypertension (SAH) and type 2 diabetes mellitus (DM2) factor that is also influenced by genetic variability. The present study aims to investigate the association between gene polymorphisms related with obesity on the prevalence of SAH and DM2 in the preoperative period and 1 year after Roux-en-Y gastric bypass surgery. Subjects and methods In total, 351 obese women in a Brazilian cohort completed the study. The clinical diagnosis of SAH and DM2 was monitored from medical records. Twelve gene polymorphisms (rs26802; rs572169; rs7799039; rs1137101; rs3813929; rs659366; rs660339; rs1800849; rs7498665; rs35874116; rs9701796; and rs9939609) were determined using real-time polymerase chain reaction and TaqMan assay. Results In the preoperative period, prevalence of SAH and DM2 was 57% and 22%, respectively. One year postoperatively, 86.8% subjects had remission of DM2 and 99.5% had control of SAH. Subjects with T allele from the serotonin receptor gene (5-HT2C, rs3813929) had five times greater chance of DM2, and the CC genotype from uncoupling protein 3 gene (UCP3, rs1800849) had three times greater chance in the preoperative period. Conclusion These findings indicate that polymorphisms rs3813929 and rs1800849 from 5-HT2C and UCP3 genes were related to DM2 prevalence among the Brazilian obese women candidates for bariatric surgery.

    Abstract Introduction: People often begin to practice exercises for periods not compatible with their level of trainability, and this could to induce a decrease in immune competence. Objective: To analyze the possible modulations in counts of circulating leukocytes and incidence of infections of the upper respiratory tract symptoms at the end of a week of concurrent training. Methods: A total of ten volunteers and sedentary male gender underwent a week of concurrent training sessions with five sequential days, with moderate intensity and duration of hundred minutes. Results: No changes were observed in leukocyte counts. As symptoms of upper respiratory tract infections, 10% of the volunteers had coryza, 20% nasal congestion, and 40% headache at the end of intervention. Conclusions: Such intervention has no potential to negatively modulate leukocyte counts. However, the incidence of symptoms of upper respiratory tract infections may be associated with decreased cellular functionality, possibly due to the volume outlined in the sessions.

    Abstract A habilidade de se recuperar e reproduzir performance em subsequentes estímulos intensos é uma capacidade demasiadamente importante em diversas modalidades esportivas intermitentes. O objetivo do presente estudo foi revisar os estudos que investigaram de forma crônica os diferentes tempos de pausa passiva no TI, seus mecanismos fisiológicos/adaptativos, a manipulação de suas variáveis e os aspectos de performance. Analisamos os mais relevantes estudos científicos originais publicados nas bases de dados Science Citation, Index, Scopus, The Scielo e National Library of Medicine, combinando as seguintes palavras chave: (recovery, repeated sprint, high intensity, interval training, rest interval). Dois estudos encontraram melhora nas pausas de curta duração e outros três estudos não observaram diferença entre os diferentes tempos de pausa passiva. Ainda não há um consenso na literatura sobre qual tempo de pausa é mais eficiente para a performance crônica do TI de alta intensidade. ABSTRACT Effects of different passive pause time during interval high intensity training The ability to recovery and reproduce performance in subsequent intense stimulus is an important to several intermittent sports. The aim of this study was to review the studies that investigated chronically different pause times passive in TI, its physiological mechanisms / adaptive manipulation of its variables and aspects of performance. Were selected articles published at journals indexed in the basis PubMed, Science Citation, Index, Scopus, The Scielo and National Library of Medicine correlating the key words: recovery, sprint repeated, high intensity, Interval training and rest interval. Two studies found improvement with a short recovery and three other studies found no difference between the different rest passive. There is still no consensus in the literature about what pause time is more efficient for the performance of chronic high intensity TI.

    Abstract INTRODUÇÃO: O intervalo de recuperação entre sessões é uma variável do treinamento de força fundamental para garantir a recuperação da capacidade neuromuscular. OBJETIVO: Comparar o efeito do tempo de recuperação entre sessões consecutivas de exercício de força sobre o desempenho neuromuscular de homens treinados. MÉTODOS: Oito homens treinados em força (21,6 ± 3,3 anos; 75,1 ± 11,3 kg; 178,2 ± 6,8 cm) realizaram duas sessões de exercício de força randomizadas e cruzadas, repetidas com intervalo de recuperação de 24h ou 48h. As sessões consistiram dos exercícios supinos reto, inclinado e declinado executadas em cinco séries de 10 repetições com intensidade de 70% de uma repetição máxima (1RM) para cada exercício. O desempenho neuromuscular pós-sessão de exercício (força, potência e velocidade), foi avaliado por meio de acelerômetro (Myotest(r)), com carga de 50% de 1RM, no exercício supino reto. RESULTADOS: Ambas as sessões (24 e 48h) apresentaram redução significante (P<0,05) na capacidade neuromuscular (força, potência e velocidade) pós-sessão de treinamento, apresentando retorno ao valor pré no intervalo de 24h (P>0,05). CONCLUSÃO: Os resultados sugerem que o intervalo de recuperação de 24h é suficiente para a recuperação do desempenho neuromuscular de membros superiores em homens treinados.
