The aim was to examine the sociodemographic predictors associated with changes in movement behaviors (physical activity, screen time, and sleep) among toddlers preschoolers during early stages of coronavirus disease 2019 pandemic Chile. Caregivers 1- 5-year-old children completed an online survey between 30 March 27 April 2020. Information about child's before (retrospectively) pandemic, as well family characteristics were reported. In total, 3157 participants provided complete data (mean...
Latin America and the Caribbean (LAC) countries, have been historically under-represented due to lack of surveillance physical behaviours in young populations. Therefore, aim this study was describe compare overall activity (PA), active transportation from school (i.e. walking or cycling), education (PE) participation, sedentary behaviour (SB) adolescents 26 countries LAC.Data were collected Global School-based Student Health Survey (2007-13). Prevalences for each compared by sex across...
Unhealthy lifestyles risk factors, such as smoking, alcohol consumption, physical inactivity, poor diet, and obesity, have been associated with a higher of all-cause cause-specific mortality. However, composite score these unhealthy behaviours has not considered, particularly in Latin American populations. Herein, we examined the association lifestyle factors mortality Mexican adults. A total 159,517 adults from Mexico City Prospective Study (MCPS) were included. Data on sociodemographic,...
Background: Body composition is a determinant of physical fitness and sports performance. Aim: To describe the anthropometric characteristics, body composition, somatotype, asymmetries 2023 world champion in C1-1000 canoeing event. Methods: Dual-energy X-ray absorptiometry (DXA), bioelectrical impedance analysis (BIA), anthropometry were used to athlete's composition. Results: The results showed fat tissue distribution 16.3% by DXA, 15.9% BIA, 19.0% anthropometry. Muscle was reported at 32.0...
Sedentary lifestyle is associated with metabolic and cardiovascular risk factors independent of physical activityBackground: behavior a main factor for disease mortality.Aim: To investigate the association between sedentary factors.Material Methods: We assessed 322 participants aged 18 to 65 years.Physical activity were measured accelerometers (Actigraph ® ).Body mass index (BMI), waist circumference, percentage body fat, diet blood markers (glucose, lipid profile, insulin HOMA-IR)...
Physical activity (PA) and sedentary behaviours (SB) are two independent risk factors for non-communicable diseases. However, there is a lack of objectively measured information on PA SB in low- middle-income countries. The aim this study was to use objective data characterise socio-demographic patterns eight Latin American 2732 participants (aged 15-65 years) from the Study Nutrition Health (ELANS) were included. collected using accelerometers. Overall country-specific average levels time...
The beneficial relationship between physical fitness and cognitive performance is affected modulated by a wide diversity of factors that seem to be more sensitive during the development stage, particularly early adolescence. This study aimed examine role considering multivariate association age, health-related quality life (HRQOL), school vulnerability index (SVI), body mass z-score (BMIz), activity, sleep problems with in boys girls.
A Mediterranean diet (MedDiet) has emerged as a crucial dietary choice, not only in attenuating various adolescents’ metabolic health issues but it also been associated with improved cognitive and academic achievement. However, few studies have established patterns of food consumption linked to both achievement adolescents living developing country non-Mediterranean-based food. Methods: This cross-sectional study included 1296 Chilean (50% girls) aged 10–14 years. The MedDiet Quality Index...
This study aims to compare adolescents' cardiometabolic risk score through an integrative classification of physical activity (PA), which involves the combination moderate-to-vigorous (MVPA) and sedentary behavior (SB).A cross-sectional derived from Healthy Lifestyle in Europe by Nutrition Adolescence Cross-Sectional Study database (2006-2008) was conducted adolescents (n = 548; boys, 47.3%; 14.7 ± 1.2 years) 10 European cities. MVPA SB were objectively measured using accelerometry....
Objective: This study aimed to compare the effects of two frequencies high-speed resistance training (HSRT) on physical performance and quality life older women. Methods: A total 24 women participated in a 12-week HSRT program composed either or three sessions/week (equated for volume intensity). Women were randomized into arms: control group (CG, n=8), performing (RT2, (RT3, n=8). The both experimental groups included exercises that required concentric muscle actions. Results: No baseline...

J Strength Cond Res 31(3): 765-772, 2017-The purpose this study was determine the adaptive response ratings perceived exertion (RPE) pain over 6 consecutive training sessions. Thirty subjects were assigned either a (BFRT) group or high-intensity resistance (HIT) group. Blood flow-restricted...
The aim was to examine the sociodemographic predictors associated with changes in movement behaviours (physical activity, screen time and sleep) among toddlers pre-schoolers during early stages of coronavirus disease 2019 pandemic Chile. Caregivers 1- 5-year-old children completed an online survey between March 30th April 27th, 2020. Information about child's before (retrospectively) pandemic, as well family characteristics were reported. In total, 3,157 participants provided complete data...
24-hour movement behaviors, including moderate-to-vigorous physical activity (MVPA), sedentary time (ST), and sleep duration, have important implications for health across the lifespan. However, no studies exist that examined integration of these behaviors in Latin America. The purpose this study was to examine prevalence meeting Canadian 24-Hour Movement Guideline recommendations sociodemographic correlates guidelines adults from eight American countries.This a multi-national...
To summarize the results of Chile's 2022 Report Card (RC) on physical activity (PA) for Children and Adolescents.
Background: The 2016 Chilean Report Card on Physical Activity for Children and Youth is a review of the evidence across indicators behaviors, settings, sources influence associated with physical activity (PA) children youth. Methods: A Research Work Group reviewed available from publications, surveys, government documents datasets to assign grade 11 PA behavior based percentage compliance defined benchmarks. Grades were as follows: , 81% 100% accomplishing given benchmark; B 61% 80%; C 41%...
Muscle strength can define the general muscular fitness (MF) measurable through hand-grip (HG), which is a factor that relates to health of people different ages. In this study we evaluated muscle together with bioimpedance electric analysis in 223 healthy Colombian adult subjects. The bioelectrical impedance vector (BIVA) was conducted determine resistance (R), reactance (Xc) and phase angle (PhA). We classified subjects into three groups (for tertiles), obtaining lower values R Xc HG, plus...
The study summarizes the findings of 2018 Chilean Report Card (RC) on Physical Activity (PA) for Children and Adolescents compares results with first RC other countries from Global Matrix 3.0.A Research Work Group using a standardized methodology 3.0 awarded grades 13 PA-related indicators based percentage compliance defined benchmarks. Different public data sets, government reports, papers informed indicators.The assigned were (1) "behaviors that contribute to overall PA levels": PA, D-;...

However, few studies representative samples have examined environmental correlates domain-specific PA in Latin America. We associations perceived a large sample adults from eight American countries. Methods This study data 8185 (aged 18–65 years) The Neighbourhood Environment Walkability Survey - Abbreviated (NEWS-A) scale was used to assess perceptions land use...

In this study, 1181 Chilean adolescents aged 10–14 years participated. A global score was computed through eight tasks, the body mass index z-score (BMIz) calculated using growth reference for school-aged adolescents. The...
