Biological maturation, fat mass and cardiorespiratory fitness in prepubescent girls: A mediation analysis
BACKGROUND: The association between indicators of maturation and measures of physical fitness are not well correlated and vary according to chronological age, sex, body size, and motor characteristics. It is known that chronological age, maturation, and fat mass are significant predictors of cardiorespiratory fitness in girls, however, the contributions of fat mass to the relationship between maturation and endurance performance are still unclear…
Autonomic Function Recovery and Physical Activity Levels in Post-Covid-19 Young Adults after Immunization: An Observational Follow-Up Case-Control Study
Coronavirus disease 2019 (COVID-19) has detrimental multi-system consequences. Symptoms may appear during the acute phase of infection, but the literature on long-term recovery of young adults after mild to moderate infection is lacking. Heart rate variability (HRV) allows for the observation of autonomic nervous system (ANS) modulation post-SARS-CoV-2 infection. Since physical activity (PA) can help improve ANS modulation, investigating factors …
Interrelationship between muscle fitness in childhood and bone mineral density in adulthood: Mediation analysis of muscle fitness in adulthood

Role of Body Mass and Physical Activity in Autonomic Function Modulation on Post-Covid-19 Condition: An Observational Subanalysis of Fit-Covid Study
The harmful effects of coronavirus disease 2019 (COVID-19) can reach the autonomic nervous system (ANS) and endothelial function. Therefore, the detrimental multiorgan effects of COVID-19 could be induced by deregulations in ANS that may persist after the acute SARS-CoV-2 infection. Additionally, investigating the differences in ANS response in overweight/obese, and physically inactive participants who had COVID-19 compared to those who did not h…

A continuous metabolic risk score was obtained from the mean of fasting glucose, triglycerides, high density lipoprotein,…
Biological maturation of youth athletes: Assessment and implications
The search for talent is pervasive in youth sports. Selection/exclusion in many sports follows a maturity-related gradient largely during the interval of puberty and growth spurt. As such, there is emphasis on methods for assessing maturation. Commonly used methods for assessing status (skeletal age, secondary sex characteristics) and estimating timing (ages at peak height velocity (PHV) and menarche) in youth athletes and two relatively recent a…
The effects of sports participation on the development of left ventricular mass in adolescent boys
OBJECTIVES: To examine the contribution of body size, biological maturation, and nonelite sports participation to longitudinal changes of left ventricular mass (LVM) in healthy boys. METHODS: One hundred and ten boys (11.0-14.5 years at baseline) were assessed biannually for 2 years. Stature, body mass, and four skinfolds were measured. Lean body mass (LBM) was estimated. Biological maturation was assessed as years from age at peak height velocit…
