    Abstract: Accelerometers are widely used to measure physical activity and sedentary behaviour amongst youth, and research participants have to wear the accelerometer for enough time to provide valid estimates of their habitual behaviour. This study aimed to identify correlates of accelerometer wear time in a sample (n = 142) of Brazilian adolescents of the 7th to the 9th grade. Students of two middle schools of Florianopolis were invited to participate. The participants answered a questionnaire, wore an accelerometer on the right hip for 10-12 days, and had their height and weight measured. The association of gender, age, socioeconomic position, mother education, conicity index, and self-reported physical activity with accelerometer wear time (minutes), number of days with ≥ 10h of valid accelerometer data, and compliance with validation criteria (≥ 4 days with ≥ 10h of wear time, including a weekend day) were tested. Accelerometer wear time in minutes was lower in boys than girls (-1014.14, 95%CI: -1822.91; -205.37). Boys also had less valid days compared to girls (Incidence Risk Ratio = 0.70; 95%CI: 0.52; 0.94) and were less likely to comply with validation criteria (Odds Ratio = 0.29; 95%CI: 0.12; 0.68). Higher mother education was associated with increased odds of meeting validation criteria. Factors associated with compliance with accelerometer protocol were sex and mother education. Thus, analyzes should consider the difference in representation of such groups.

    Abstract: RESUMEN La autoliberación miofascial con foam roller se ha utilizado como estrategia para acelerar el proceso de recuperación. Esta revisión sistemática tuvo como objetivo investigar cómo una o varias sesiones de autoliberación miofascial con foam roller afectan la recuperación del desempeño de los atletas. La investigación se llevó a cabo en las bases de datos PubMed, Scopus, Cochrane Library, BVS, Embase, SPORTDiscus, ScienceDirect y Google Scholar utilizando los términos: “foam rolling”; “foam roller”; “self-myofascial release” combinados con “recovery”, “exercise”, “fatigue”, “sport”; y “acute effects”, “chronic effects”, “performance”, que dan como resultado 12.020 artículos. Tras verificar los criterios de inclusión, se seleccionaron y analizaron 40 estudios. Se concluyó que las sesiones múltiples de autoliberación miofascial con foam roller son más efectivas para recuperar el desempeño de potencia de las extremidades inferiores y velocidad que una sola sesión. Una sesión es más efectiva para recuperar el desempeño de fuerza que múltiples sesiones. Además, una sesión y varias sesiones demostraron resultados similares en la recuperación de la agilidad, el dolor, la flexibilidad, la eliminación del lactato en sangre y la percepción de recuperación. Por último, las sesiones múltiples entre series de ejercicios de resistencia parecen reducir el desempeño, al disminuir el número de repeticiones y la resistencia a la fatiga, mientras que una sola sesión no causó un efecto significativo. La autoliberación miofascial con foam roller demuestra su potencial de acelerar el proceso de recuperación de los atletas. Estudios futuros deberán evaluar el efecto del uso crónico de la autoliberación miofascial con foam roller en la recuperación del desempeño. Nivel de evidencia II; Revisión sistemática.

    Abstract: Os distúrbios do sono são considerados um dos problemas que mais afetam a população idosa no mundo e estão relacionados a consequências negativas para saúde, como depressão, incapacidade funcional e disfunções cognitivas. Um dos fatos relacionados com o surgimento de distúrbios envolve a insuficiência do dispêndio enérgico advindo do baixo nível de atividade física, porém ainda não se sabe a quantificação exata para ocasionar este desfecho. Nesse sentido, o objetivo do estudo foi analisar o poder preditivo e identificar os pontos de corte do número de passos (NP) para a percepção negativa de sono (PNS) em idosas. Participaram 122 mulheres (68,5±5,12 anos), que fizeram o uso de sensores de movimento (pedômetro) para medida do NP durante uma semana. Para o cálculo do número de passos/dia foi realizada pela média do número de passos durante sete dias de uso do pedômetro. A qualidade do sono foi avaliada por uma questão integrada ao questionário sociodemográfico, na qual arguia: “Nos últimos 30 dias com que frequência a senhora considera que dorme bem?”. A partir das respostas, foram dicotomizados dois grupos, o de percepção positiva do sono e PNS. Para estimar o poder discriminatório e pontos de corte para NP e a PNS foram construída curva ROC (p

    Abstract: The aim of this study was to examine the association of physical activity with depression and cognition deficit, separately and combined, in Brazilian older adults. We analyzed data from 622 older adults. Physical activity was assessed using the International Physical Activity Questionnaire. Depressive symptoms were assessed using the Geriatric Depression Scale, while cognitive deficit was assessed using the Mini-Mental State Examination. Multinomial logistic regressions were used to assess associations of depression and cognitive deficit with sociodemographic, health, and behavioral variables. Prevalence of physical inactivity ( 〈 150 min of moderate-to-vigorous physical activity/week), depression, and cognitive deficit were 35.7%, 37.4%, and 16.7%. Physical inactivity was associated with depression (OR: 1.83, 95% CI: 1.14–2.94) and with depression and cognitive deficit combined (OR: 4.23, 95% CI: 2.01–8.91). Physically inactive participants were also more likely to present limitations in orientation and language functions. Physical inactivity was associated with depression and also with depression and cognitive deficit combined in older adults.

    In: Journal of Aging and Physical Activity, Human Kinetics, Vol. 31, No. 5 ( 2023-10-1), p. 733-742
    Abstract: This study investigated the direct and indirect associations of physical activity and sedentary behavior with survival time in older adults. Prospective population-based cohort study used exploratory survey-type methods and physical performance tests in 319 adults aged ≥60 years. Trajectory diagrams were used to represent the initial hypothetical and final models with the relationships of independent, mediating, and dependent variables. Physical activity was indirectly associated with survival time and was mediated by instrumental activities of daily living and functional performance. In contrast, instrumental activities of daily living, functional performance, the number of hospitalizations, and medications mediated the association between duration of sedentary behavior and survival time. The explanatory power of the final model was 19%. Future efforts should focus on increasing the participation and adherence of older adults to exercise programs to improve their physical functions and general health, which may increase their health period and, consequently, their survival time.

    In: Journal of Physical Activity and Health, Human Kinetics, ( 2023), p. 1-8
    Abstract: Background : Recent statistical approaches have allowed consideration of the integrated relationships between sedentary behavior (SB) and physical activity (PA) with different health outcomes. The present paper aimed to systematically review the literature and synthesize evidence about associations between hypothetical reallocations from SB to different PA intensities and cardiovascular risk factors in youth. Methods : A systematic search of 8 databases was performed. Observational studies with a population of children and/or adolescents and based on statistical analysis that investigated the associations between time reallocations from SB to PA and cardiovascular risk factors were included. Results : Twenty-eight studies met the inclusion criteria. Level of evidence (derived from cross-sectional studies) indicated that the reallocation from SB to moderate to vigorous PA was beneficially associated with adiposity, cardiorespiratory fitness, and cardiometabolic biomarkers in youth. Reallocation from SB to light PA was not associated with the analyzed outcomes. Associations derived from longitudinal studies were mostly inconclusive. Conclusion : Cardiovascular risk factors could be improved by increasing moderate to vigorous PA at the expense of time spent in SB in pediatric populations. Prospective studies or studies investigating the effects of reallocating sedentary bouts to PA are needed.

    Abstract: Quality of life is influenced by several factors and one aspect that has been negatively associated with health is sedentary behavior. Thus, the purpose of this study was to investigate the association between sitting time and quality of life in older adults. Methods: This was a cross-sectional study conducted with individuals ≥60 years old residing in 24 Brazilian municipalities. Total sitting time was evaluated according to self-report of sitting time on a regular weekday and usual weekend day. The quality of life was evaluated by the WHOQOL-BREF and WHOQOL-OLD instruments. Results: 3206 older adults were analyzed. In the univariate logistic regression analysis, all domain and facets of quality of life were associated to the longest sitting time; however, in the multivariate analysis, only the physical domain and the social participation facet remained significant in the model. After adjustment for sex, age group, education and regular practice of physical activity, longest sitting time remained associated with the lowest score for the physical domain (OR = 1.80; 95% CI: 1.39–2.34) and social participation facet (OR = 1.42; 95% CI: 1.10–1.84). Conclusions: In this study, older adults who sat the most presented the worst scores in the physical domain and social participation facet of quality of life.

    Abstract: O objetivo deste estudo foi analisar o comportamento da pressão arterial (PA) em adolescentes com excesso de peso após uma sessão de high intensity interval training (HIIT) na esteira ergométrica. Trata-se de uma pesquisa com delineamento cross-over aleatorizado, a amostra foi formada por 11 adolescentes do sexo masculino, 81,81% com obesidade e idade entre 15 e 18 anos. Os voluntários realizaram dois protocolos experimentais: controle e HIT. O protocolo HIIT foi constituído de cinco séries de 85 a 95% do VO2pico por um minuto, intercalados por três minutos de recuperação de 40 a 50% do VO2pico. Antes e após os protocolos, os  parâmetros  hemodinâmicos  foram  obtidas  por  meio  de  um  monitor  automático  (SpaceLabs  90207),  programado para realizar medidas a cada 20 minutos no período das 12:00 às 22:00 horas. Foi observado diferença signifi  cativa entre as médias da pressão sistólica nos protocolos controle e HIIT somente na primeira hora após o fi nal do exercício (131,90±7,93 vs 124,18±7,56 mmHg). A comparação entre os protocolos e as medidas hemodinâmicas pré-sessão e média pós-sessão (10 horas) demonstrou que o HIIT promoveu uma redução signifi cativa na pressão arterial média em comparação a pré-sessão. Em conclusão, o protocolo HIIT empregado promoveu efeito hipotensor de baixa magnitude sobre as medidas hemodinâmicas pós-exercício no que diz respeito a PAS.
