Public Open Spaces and Leisure-Time Walking: A Longitudinal Study With Brazilian People in the COVID-19 Pandemic.

Aim: To examine whether changes in public open spaces (POS) were associated with leisure-time walking (LTW) between 2014 and 2021.

Methods: The sample comprised a prospective cohort of individuals living in São Paulo City, Brazil. The baseline sample was collected in 2014/2015 (4042 people aged 12 y or older) and the second wave in 2020/2021 (1431 people aged 18 y or older, 35.

Validity of self-reported body mass and height: relation with sex, age, physical activity, and cardiometabolic risk factors.

Objective: To evaluate the validity of self-reported body mass and height measurements in adolescents, adults and older adults according to sex, age, leisure-time physical activity level, nutritional status, and cardiometabolic risk factors.

Methods: The study included 856 subjects, aged 12 years or older, who participated in the São Paulo Health Survey (ISA-2015) and who had their body mass and height measured and self-reported. Based on the Body Mass Index (BMI), a classification of nutritional status was made according to standardized criteria for each phase of life.

Study protocol: health survey of Sao Paulo: ISA-Physical Activity and Environment.

Background: Many studies have investigated the association between the built environment and physical activity behavior in urban settings. However, most of the studies conducted in low- and middle-income countries were cross-sectional, which are limited to identify behavioral determinants. We propose a prospective cohort study to verify the relationship between built environment features and leisure-time and transport-related physical activity in adults from Sao Paulo city, Brazil.

Cyclists' noise exposure in a Brazilian medium-sized city.

This study aimed to assess cyclists' exposure to noise in a medium-sized Brazilian city. Mobile sensors were used to conduct noise measurements in streets with and without dedicated cycling infrastructures. The method can be summarized in the following procedures: i) characterization of the study area; ii) data collection and validation; iii) calculation of exposure indicators; and iv) comparison and representation of the results on maps.

Health related quality of life is differently associated with leisure-time physical activity intensities according to gender: a cross-sectional approach.

Background: Several studies have demonstrated a positive association between physical activity (PA) and health-related quality of life (HRQL). However, studies have suggested that this association depends both on the PA intensity and the domain of HRQL evaluated. This study aimed to explore the association between physical, mental and overall HRQL with recommended levels of PA.

Effect on physical fitness of a 10-year physical activity intervention in primary health care settings.

Background: Interventions in primary health care settings have been effective in increasing physical fitness. In 2001, the Programa de Exercício Físico em Unidades de Saúde (Physical Exercise in Health Primary Care Program-PEHPCP) was launched in Rio Claro City, Brazil. The intervention consisted of biweekly, 60-minute group sessions in all primary health care settings in the city.

Cultural adaptation and validation of the KINDL questionnaire in Brazil for adolescents between 12 and 16 years of age.

Objective: Obtain a Portuguese version of the Kiddo-KINDL questionnaire that is semantic and culturally equivalent to the original version.

Methods: For the adaptation, the methodology of direct and inverse translation was used. The questionnaire was applied to groups from three schools in Uberlândia, MG - Brazil, and comprised of 378 children and adolescents aged between 12 and 16.

Effects of swimming training on tissue glycogen content in experimental thyrotoxic rats.

Thyrotoxicosis, a condition in which there is an excessive amount of circulating thyroid hormones, leads to reduced glycogen content in different tissues. In this study we analyzed the effects of aerobic swimming training on liver, heart, and skeletal muscle glycogen content in experimentally induced thyrotoxicosis. Wistar male rats were divided into euthyroid sedentary (ES, n = 12), euthyroid trained (ET, n = 11), thyrotoxic sedentary (TS, n = 12), and thyrotoxic trained (TT, n = 10) groups.

Exercise and spirulina control non-alcoholic hepatic steatosis and lipid profile in diabetic Wistar rats.

Background: Diabetes mellitus is associated with metabolic dysfunctions, including alterations in circulating lipid levels and fat tissue accumulation, which causes, among other pathologies, non-alcoholic fatty liver disease (NAFLD).

Aim Of The Study: The objective of this study was to analyse the effects of physical exercise and spirulina intake on the control of NAFLD in diabetic Wistar rats.

Methods: Diabetes was induced in the animals through intravenous administration of alloxan.
