The Influence of Competitive Level on Sleep Quality and Quality of Life in Adolescent Soccer Players.

Introduction Soccer is one of the most popular sports worldwide and is a leading physical activity choice among adolescents. This study aims to investigate how the competitive level of adolescent soccer players impacts their sleep quality and quality of life. Methods  A total of 5,692 adolescents aged 11 to 19 years were classified based on their physical activity levels and competitive engagement.

The kinetics of cardiac troponin T release during and after 1- and 6-h maximal cycling trials.

Objectives: In this study, the effects of short-duration high-intensity exercise and long-duration exercise on high-sensitivity cardiac troponin T (hs-cTnT) levels were compared.

Methods: Twelve male amateur cyclists performed 1- and 6-h cycling trials. In both exercise trials, hs-cTnT was assessed at rest, immediately postexercise and at 1, 3, 6, 12, and 24 h postexercise.

Sport practice and depression during adolescence: Special emphasis on performance level and sport discipline.

Objectives: Depression is one of the most prevalent diseases worldwide, with almost half of the adolescent population affected according to latest research. Given this serious burden of disease, research points toward interventions that could effectively fight this disease in this population subset. One of these pivotal interventions is physical activity, although the effects of different sport types and sport performance level on depression have not yet been studied in adolescent populations.

Physical Activity and Sleep Quality in Spanish Primary School Children: Mediation of Sex and Maturational Stage.

Background: sleep is a physiological process that is critical for physical and mental health in children. Childhood encompasses diverse developmental stages that may affect the impact of physical activity on sleep quality, which may also be influenced by sex. The purpose of this study was to examine the mediation effect of sex and, as well as maturational stage on the association between physical activity and sleep quality, among primary school children.

Sleep quality is mediated by physical activity level in adolescents.

Background: Sleep is essential for the adolescent's health and well-being. Despite existing evidence of the positive relationship between physical activity and quality of sleep, some other factors could mediate this association. The purpose of the present study was to clarify the interaction between the level of physical activity and sleep in adolescents depending on their gender.
