Convergent Validation of a Self-Reported Commuting to and from School Diary in Spanish Adolescents.

Unlabelled: The aim of this study was to examine the convergent validity of self-reported diary times for commuting to and from school with device-measured positional data (Global Positioning System; GPS) in Spanish adolescents.

Methods: Cross-sectional data were obtained from four Spanish public secondary schools in 2021, comprising 47 adolescents and 141 home-school and school-home trips. Participants self-reported the time they left and arrived at home and school through a commuting diary.

The Effect of a School-Based Intervention on Children's Cycling Knowledge, Mode of Commuting and Perceived Barriers: A Randomized Controlled Trial.

The low rates of active commuting to/from school in Spain, especially by bike, and the wide range of cycling interventions in the literature show that this is a necessary research subject. The aims of this study were: (1) to assess the feasibility of a school-based cycling intervention program for adolescents, (2) to analyse the effectiveness of a school-based cycling intervention program on the rates of cycling and other forms of active commuting to/from school (ACS), and perceived barriers to active commuting in adolescents. A total of 122 adolescents from Granada, Jaén and Valencia (Spain) participated in the study.

The Physical Education Class Perceived by Schoolchildren from 6 to 8 Years Old Expressed through Drawings.

Physical Education is one of the subjects that arouses the most interest in children. The aim of this study is to find out the opinion that primary school students have about the Physical Education class. Drawings from a sample of 62 students from an educational centre in the city of Jaén, aged between six and eight years old, were analysed.

A School-Based Randomized Controlled Trial to Promote Cycling to School in Adolescents: The PACO Study.

This manuscript describes the rationale and protocol of a school-based randomized controlled trial called "Cycling and Walk to School" (PACO, by its Spanish acronym) that aims to promote cycling to and from school and physical activity (PA) in adolescents. This study will examine the effects of this intervention in cycling and active commuting to and from school (ACS), PA and several ACS-related factors based on self-determination theory (SDT) and a social-ecological model (SEM). A total of 360 adolescents attending six high schools (three experimental and three control) from three Spanish cities will participate in this randomized controlled trial.

Systematic Review of the Literature About the Effects of the COVID-19 Pandemic on the Lives of School Children.

The year 2020 has been marked by the emergence of coronavirus disease 2019 (COVID-19). This virus has reached many countries and has paralyzed the lives of many people who have been forced to stay at home in confinement. There have been many studies that have sought to analyze the impact of this pandemic from different perspectives; however, this study will pay attention to how it has affected and how it may affect children between 0 and 12 years in the future after the closure of schools for months.

Use of the Smartphone and Self-Concept in University Students According to the Gender Variable.

The university stage comprises a very important and vital period in the modification of students' lifestyles, and these changes can affect their self-concept. The excessive use of technology today can also influence the formation of their identity. The aim of this study is to analyze the relationship between self-concept and the use of the smartphone by university students in terms of gender.

Motivational Climate Is Associated with Use of Video Games and Violence in Schoolchildren: A Structural Equation Model According to Healthy Behaviors.

The aim of this cross-sectional study was to develop an explanatory model of motivational climate, problematic use of videogames, violent behaviour and victimisation in schoolchildren. The sample included 734 children aged between 10 and 12 years of age from the province of Granada (Spain). A multi-group structural equation model was used, with an excellent fit (CFI = 0.

Mini Review of the Use of the Mobile Phone and Its Repercussion in the Deficit of Physical Activity.

Background: Current technology has the ability to distract and evade its users, this resulting in an addiction or "escape" from the real world. The excessive use of smartphones can cause a decrease in physical activity (PA) for many people prefer to use these devices rather than do the recommended physical exercise.

Objective: The objective of this paper is to analyze the possible relation between the use of smartphones and the reduction in the practice of PA that is reflected in scientific articles.

Effects of electrostimulation and plyometric training program combination on jump height in teenage athletes.

The purpose of this study was to examine the effects of eight-week (2 days/week) training periods of plyometric exercises (PT) and neuromuscular electrostimulation (EMS) on jump height in young athletes. Squat jump (SJ), counter movement jump (CMJ) and drop jump (DJ) were performed to assess the effects of the training protocols 98 athletes (100 & 200m and 100m & 110m hurdles) voluntarily took part in this study, 51 males (52%) and 47 females (48%), 17.91 ± 1.

Jump peak power assessment through power prediction equations in different samples.

The aim of this study was to describe the characteristics of jump capacity in a group of secondary school students and to develop 2 specific equations-applied to boys and girls, respectively, to estimate the jump power of secondary school students. Four hundred and fifty-six boys (age, 14.1 ± 0.
