PURPOSE: Premenarcheal female gymnasts have been consistently found to have greater bone mass and structural advantages. However, little is known about whether these structural advantages are maintained after the loading stimulus is removed. Therefore, the purpose of this study was to investigate structural properties at the hip after long term retirement from gymnastics. METHODS: Structural properties were derived from Dual Energy X-ray Absorptiometry scans using the hip structural analysis program for the same 24 gymnasts and 21 non-gymnasts both in adolescence (8-15 yrs) and adulthood (22-30 yrs)...

PURPOSE: The decline of physical activity in children is considered an important determinant to explain the rising rates of obesity. However, this risk may be augmented in children who are genetically susceptible to increased weight gain. We hypothesised that a sedentary lifestyle and moderate activity will interact with genetic loci, resulting in differential effects in relation to obesity risk. METHODS: We recruited 643 European children born to participants in the New Zealand based Screening for Pregnancy Endpoints (SCOPE) study...

PURPOSE: Understanding the correlates of children's fitness as they develop is needed. The objectives of this study were to: (1) examine the longitudinal associations between physical activity (PA), screen time (ST), and fitness, (2) determine if sex moderates associations, and (3) track PA and ST over three years. METHODS: Findings are based on 649 children (baseline: 4.5±0.5 years; follow-up: 7.8±0.6 years) from Edmonton, Canada. Parental-reported hour/week of PA and ST were measured at baseline and three years later...

PURPOSE: Balance training studies in children reported conflicting results without evidence for improvements in children under the age of eight. The aim of this study therefore was to compare balance training adaptations in children of different age groups to clarify whether young age prevents positive training outcomes. METHOD: The effects of five weeks of child-oriented balance training were tested in 77 (38 girls; 39 boys) participants of different age groups (6-7, 11-12, and 14-15 years) and compared to age-matched controls...

PURPOSE: The goal of the current work is to challenge the enduring notion that pre-puberty is the optimum timing for maximum bone response to exercise in childhood, and to present the evidence that early puberty is a more a potently receptive period. METHOD: The relevant literature is reviewed and the causes of the misconception addressed in detail. RESULTS: Contrary to prevailing opinion, ample evidence exists to suggest the peri-pubertal years represent the developmental period during which bone is likely to respond most robustly to exercise intervention...

The prevalence of childhood obesity has increased at an alarming rate. The increased obesity rate in pediatrics parallels the increased risks for developing metabolic abnormalities such as insulin resistance, type 2 diabetes (T2DM), and non-alcoholic fatty liver disease (NAFLD). In particular, the strong relationship between obesity and such health consequences are well explained by the excessive accumulation of depot-specific body adiposity such as visceral adipose tissue (VAT), intrahepatic lipid content, intermuscular AT (IMAT), and/or intramyocellular lipid (IMCL) content...

PURPOSE: To examine the influence of vigorous physical activity (VPA) bout frequency on bone strength accrual across adolescence, independent of total volume of VPA. METHOD: We measured VPA (6 METs; total volume and bout frequency < 5 min in duration) annually using waist-worn accelerometers (ActiGraph GT1M) in 309 adolescents (9-20 years at baseline: 99, <13 years; 126, 13-18 years; 84, >18 years) over a maximum of 4 years. We applied finite element analysis to high-resolution peripheral quantitative computed tomography scans of the distal tibia (8% site) to estimate bone strength (failure load; F...

This study examined resting levels of catabolic and anabolic osteokines related to Wnt signaling and their responses to a single bout of plyometric exercise in child and adolescent females. Fourteen pre-menarcheal girls (10.5 ± 1.8 years old) and 12 post-menarcheal adolescent girls (15.0 ± 1.0 years old) performed a plyometric exercise trial. One resting and three post-exercise blood samples (5 min, 1h, 24h post-exercise) were analysed for sclerostin (SOST), dickkopf-1 (DKK-1), osteoprotegerin (OPG), receptor activator of nuclear factor kappa-β ligand (RANKL) and transforming growth factors (TGF-β1, TGF-β2 and TGF-β3)...
