Association of postural education and postural hygiene with low back pain in schoolchildren: Cross-sectional results from the PEPE study.

Background: Low back pain (LBP) is the leading cause of disability in the world that affects the population of all ages globally. The main aim of the present study was to analyze the cross-sectional association of postural education and postural hygiene habits with LBP, differentiating between frequency and intensity of pain.

Methods: This cross-sectional study assessed 849 students aged 10-12 years from primary schools.

Investigating the direct and indirect effects of a school-based leadership program for primary school students: Rationale and study protocol for the 'Learning to Lead' cluster randomised controlled trial.

Background: Leadership is a valuable skill that can be taught in school, and which may have benefits within and beyond the classroom. Learning to Lead (L2L) is a student-led, primary school-based leadership program whereby older 'peer leaders' deliver a fundamental movement skills (FMS) program to younger 'peers' within their own school.

Aim: The aims of the study are to determine the efficacy of a peer-led FMS intervention on: (i) peer leaders' (aged 10 to 12 years) leadership effectiveness (primary outcome), leadership self-efficacy, well-being, and time on-task in the classroom; (ii) peers' (aged 8 to 10 years) physical activity levels, actual and perceived FMS competency, cardiorespiratory fitness, muscular power, and executive functioning; and (iii) teachers' (referred to as 'school champions') work-related stress and well-being.

Efficacy of Different Modalities and Frequencies of Physical Exercise on Glucose Control in People with Prediabetes (GLYCEX Randomised Trial).

To assess the efficacy of different modalities and frequencies of physical exercise on glycaemic control in adults with prediabetes. A two-phase, parallel, randomised, controlled clinical trial will be carried out, in 210 participants. In phase 1, 120 participants will be randomized into four arms: (1) aerobic exercise, (2) aerobic exercise combined with resistance, (3) high-intensity intervallic exercise and (4) control group.

Association between Physical Fitness and Low Back Pain: The Pepe Cross-Sectional Study.

Background: Recent studies have shown that the lifetime prevalence of low back pain (LBP) in schoolchildren aged 10-12 years is 73.6%, and that it appears to have an impact on people's quality of life. A wide range of risk factors associated with LBP have been studied.

Knowledge of Low Back Pain among Primary School Teachers.

Low back pain (LBP) is a prevalent musculoskeletal disease that affects a large percentage of the working population, including teachers. The World Health Organization has identified the school as an effective environment for improving child health. For this reason, the figure of the teacher is a fundamental piece in the process of knowledge acquisition about postural education and prevention of LBP among schoolchildren.

The effects of a physical activity intervention based on a fatness and fitness smartphone app for University students.

Since the 2012 Lancet Series on physical activity, progress regarding this topic has been negligible at global level. Thus, improving physical activity levels in specific populations through new methodologies is positioned as a priority. The aim of this study was to determine the effects of a physical activity intervention on body fatness composition, and measured and self-reported physical fitness components based on the use of a smartphone app.

Active commuting to school among 36,781 Spanish children and adolescents: A temporal trend study.

This study examines trends in the rates of active commuting to school (ACS) in Spanish children (n = 18 343; 8.93 ± 1.68) and adolescents (n = 18 438; 14.

Associations of Heart Rate Measures during Physical Education with Academic Performance and Executive Function in Children: A Cross-Sectional Study.

The current evidence for a relation between children's heart rate measures and their academic performance and executive functioning is infancy. Despite several studies observing dose-response effects of physical activity on academic performance and executive function in children, further research using objective measures of the relative intensity of physical activity (e.g.

The relative age effect on physical fitness in preschool children.

The aim of the present study was to investigate the existence of a relative age effect (RAE) on physical fitness of preschoolers. Anthropometry and physical fitness were assessed in 3147 children (3-5 years old) using the PREFIT battery. Based on the birth year, participants were divided into 3year groups (3-, 4- and 5-years).

A Single Question of Parent-Reported Physical Activity Levels Estimates Objectively Measured Physical Fitness and Body Composition in Preschool Children: The PREFIT Project.

Physical inactivity is recognized as a determinant of low physical fitness and body composition in preschool children, which in turn, are important markers of health through the lifespan. Objective methods to assess physical activity, physical fitness and body composition in preschool children are preferable; however, they have some practical limitations in the school context. Therefore, the aim of this study was to test whether a single question regarding physical activity level of preschool children, reported by their parents, could be used as an alternative screening tool of physical fitness and body composition.

Physical fitness reference standards for preschool children: The PREFIT project.

Objectives: Reference values are necessary for classifying children, for health screening, and for early prevention as many non-communicable diseases aggravate during growth and development. While physical fitness reference standards are available in children aged 6 and older, such information is lacking in preschool children. Therefore, the purposes of this study were (1) to provide sex-and age-specific physical fitness reference standards for Spanish preschool children; and (2) to study sex differences across this age period and to characterise fitness performance throughout the preschool period.

Sports participation and low back pain in schoolchildren.

Background: Low back pain (LBP) is one of the biggest health problems worldwide.

Objectives: The purpose of this study was to investigate the association between sports participation (duration and type) and LBP related outcomes in childhood.

Methods: This cross-sectional study involved 5th and 6th grade primary school students.

A Mediation Analysis on the Relationship of Physical Fitness Components, Obesity, and Academic Performance in Children.

Objectives: To examine the relationship between a battery of obesity indicators and physical fitness components with academic performance in children and to explore the combined and mediation role of the physical fitness components in the relationship between obesity and academic performance in children.

Study Design: A cross-sectional study including data from 250 Spanish schoolchildren (Balearic Islands) between 10 and 12 years of age (mean age, 10.98 ± 0.

Effects of a Whatsapp-delivered physical activity intervention to enhance health-related physical fitness components and cardiovascular disease risk factors in older adults.

Background: This pilot study evaluated the feasibility and preliminary effectiveness of a 10-week WhatsApp-based intervention aimed at enhancing health-related physical fitness components and cardiovascular disease (CVD) risk factors compared with a face-to-face condition.

Methods: Participants (N.=32) were assigned to one of three groups: training group (N.

Increasing physical activity through mobile device interventions: A systematic review.

Physical inactivity is a health problem that affects people worldwide and has been identified as the fourth largest risk factor for overall mortality (contributing to 6% of deaths globally). Many researchers have tried to increase physical activity levels through traditional methods without much success. Thus, many researchers are turning to mobile technology as an emerging method for changing health behaviours.
