"Active behaviour of parents is more associated with out-of-school physical activity in their children".

Background: Active parents may have more active children, as parents act as role models for their children's physical activity (PA). Parents can facilitate access to PA, provide information, validate physical-sport behaviours, and offer emotional support. Also, the influence of parents' PA on children's PA in and out of the school context has not been well-established.

Changes in youth's physical activity: influence on screen time and cardiometabolic risk after 2-year follow-up.

This study aimed to verify the moderation role of changes in leisure physical activity (PA) practice in the association between screen time (ST) at baseline and cardiometabolic risk score (cMetS) at 2-year follow-up in children and adolescents. Observational longitudinal study included 333 children and adolescents (6-17 years), both sexes (girls n = 141), from public and private schools. Participants were evaluated in 2014 and 2016.

Promoting active behaviours in schoolchildren using the socio-ecological model in the physical education class: study protocol of the ACTIBESE project.

Background: The correlation between parental and child physical activity levels has been the subject of significant investigation. Existing research has illuminated this association, particularly emphasising its influence during childhood. However, as children transition into adolescence, this relationship appears to weaken.

Results From the First Para Report Card on Physical Activity for Children and Adolescents With Disabilities in Chile.

Background: Global initiatives have been put in place to attain a thorough understanding of worldwide variations in physical activity (PA) among children and adolescents. Yet, there is limited knowledge about PA-related indicators, specifically for children and adolescents with disabilities (CAWD). To bridge this data gap, the Global Matrix of Para Report Cards (PRCs) of CAWD initiative was established to address the scarcity of information on PA for this population globally.

Does Co-Supplementation with Beetroot Juice and Other Nutritional Supplements Positively Impact Sports Performance?: A Systematic Review.

In the pursuit of enhanced athletic prowess in different disciplines, athletes constantly look for strategies to increase their physical performance, encompassing technical skills and dietary components, which inevitably, in most cases, include the incorporation of sports supplements. In recent years, there has been an increase in the number of athletes using ergogenic aids. In this context, scientific evidence must play a prominent role in either endorsing or warning against the use of these products, ensuring the preservation of health while promoting the theoretically established positive benefits.

Speed, agility, and musculoskeletal fitness are independently associated with areal bone mineral density in children.

There is still little understanding of the associations between physical fitness variables and bone health in children taking into account key confounders. The aim of this study was to analyze the associations between performance in tests of speed, agility, and musculoskeletal fitness (power of the upper and lower limbs) with bone mass of different regions in children, considering the adjustment to maturity-offset, lean percentage, and sex. Cross-sectional study design: the sample consisted of 160 children aged 6-11 years.

Characterizing the interindividual postexercise hypotension response for two order groups of concurrent training in patients with morbid obesity.

Postexercise hypotension (PEH) is a common physiological phenomenon occurring immediately after endurance training (ET), resistance training (RT), and ET plus RT, also termed concurrent training (CT); however, there is little knowledge about the interindividual and magnitude response of PEH in morbidly obese patients. The aims of this study were (1) to investigate the effect of CT order (ET + RT vs. RT + ET) on the blood pressure responses; 2) characterize these responses in responders and nonresponders, and 3) identify potential baseline outcomes for predicting blood pressure decreases as responders.

Which one? A comparative study of traditional and sports uniforms on academic achievement, cognitive performance, playtime, bullying, and discrimination in adolescents: The Cogni-Action Project.

Objective: The aim of this study was to compare academic achievement, cognitive performance, playtime, bullying, and discrimination in adolescents according to traditional uniforms (TUs) and sports uniforms (SUs) worn at school, while simultaneously exploring the influence of the school vulnerability index.
