Developmental Changes Of Left Ventricular Mass During Pubertal Years Using Static And Ontogenetic Allometric Exponents In Boys Aged 11-14 Years

  • Presented on May 29, 2014

Purpose: Using static, ontogenetic and multilevel allometric modelling, objectives of the study were twofold: to estimate inter- and intra-individual effects of body size descriptors on the development of LVM in adolescent boys, and to examine independent and combined effects of physical activity (PA), sedentary time and biological maturity status on ...


Physical Activity and Physical Fitness in Adolescents With and Without Autism Spectrum Disorders
