Factors Influencing the Likelihood of Alcohol and Tobacco Use in Adolescent Athletes: Type of Sport, Age, and Action Tendencies in Sport.

This article proposes a new approach to understand substance use among adolescent athletes. Thus, this article describes an investigation of the likelihood of alcohol and tobacco use in adolescent athletes considering the type of sport, age, gender, and their action tendencies. A total of 552 athletes with an age range of 12-16 years were engaged in medium-high-contact sports ( = 291) and non-contact sports ( = 261).

Impact of Teachers' Autonomy Support in Students' Basic Psychological Needs, Intrinsic Motivation and Moderate-to-Vigorous Physical Activity.

The students' active participation in physical education does not always guarantee the fulfilment of the international guidelines on moderate-to-vigorous physical activity (MVPA). The goal of the study was to examine the effects of the teacher autonomy support on the MVPA, basic psychological needs, and intrinsic motivation of primary education students. A three-phase, crossed research design was used in four groups of primary education (grades three, four, five, and six).

Self-made material in physical education: Teacher perceptions of the use of an emerging pedagogical model before and during the COVID-19 pandemic.

The COVID-19 pandemic caused drastic changes in education, which had to adapt to changing scenarios (online, face-to-face, hybrid teaching). Within physical education (PE), strategies such as 'do not use or share equipment' were proposed to avoid infections. These strategies fit with an emerging pedagogical model called the Self-made Material Model (SMM), which involves students creating their own PE equipment.

Physical Activity and Physical Fitness in Adolescents after the COVID-19 Lockdown and One Year Afterward.

The purpose of this study was to analyze the changes in physical activity and physical fitness between the beginning of the first academic year after a confinement (November 2020) and the beginning of the second academic year after a confinement ("new normality": November 2021) in a cohort of adolescents. Moreover, the evolution of physical fitness after controlling for physical activity was examined. A total of 687 students ( = 15.

A Longitudinal Examination of Withholding All or Part of School Recess on Children's Physical Activity and Sedentary Behavior: Evidence from a Natural Experiment.

School recess is a daily opportunity for school-age students to be physically active. However, in some territories teachers often use recess for other purposes (e.g.

Physical Activity and Prevention of Depressive Symptoms in the Spanish Population during Confinement due to COVID-19.

Background: In March 2020, the Spanish government established an official lockdown across the country in response to the COVID-19 pandemic and confined the population to their homes, restricting their mobility. The objectives of the study are twofold: a) to examine dose-response relationships between physical activity (PA) components (volume, intensity, frequency, duration) and depressive symptoms of the population during confinement, and b) to identify the optimal levels of PA to mitigate notable depressive symptoms (NDS).

Methods: 4,811 (2,952 women) Spanish citizens, age range 16-92 years, completed an online questionnaire (snowball sampling) to measure their levels of depressive symptoms, PA, and various anthropometric and sociometric variables.

A longitudinal study on depressive symptoms and physical activity during the Spanish lockdown.

: The aim was to evaluate the evolution of depressive symptoms and to explore the influence of physical activity (PA) practice during the home confinement due to the COVID-19 outbreak in Spain. : Information was collected from 595 confined participants who reported personal and contextual information, depressive symptoms and PA levels at four time points. : The changes in depressive symptoms were analyzed using a linear mixed model with cubic splines.

Resilience and physical activity in people under home isolation due to COVID-19: A preliminary evaluation.

Background: The recent shelter-in-place order issued by the Spanish government (due to the outbreak of the COVID-19) forced the Spanish population to self-isolate at home. The psychological and social effects of this new situation are unknown. Therefore, this study aimed to examine the impact of such scenario on citizens' resilience, as well as the connections between resilience, physical activity (PA), gender, weight and body mass index (BMI) before and after confinement, and COVID-19-related information.

COVID-19, Psychological Well-being and Physical Activity Levels in Older Adults During the Nationwide Lockdown in Spain.

Objective: The novel coronavirus disease (COVID-19) has forced nationwide lockdowns in many countries. As a result, most of the Spanish population had to self-isolate at home. The physical and psychological consequences of this unexpected scenario could be particularly worrisome for people older than 60 years.

Weight changes during the COVID-19 home confinement. Effects on psychosocial variables.

Introduction: The goal was to assess individuals' weight changes and their connections with depressive symptoms, optimism and physical activity.

Method: 4379 Spanish citizens, 16-84 years, participated.

Results: Most participants declared no weight changes.

A self-determination approach to the understanding of the impact of physical activity on depressive symptoms.

The purpose was to test a new motivational sequence. It was hypothesized that more autonomous forms of motivation would predict the intensity of physical activity (PA), which in turn, would predict depressive symptoms. In order to evaluate self-determined motivation, the Self-Determination Index (SDI) was used.
