OBJECTIVE:

To develop sex-specific and age-specific normative values for the nine Eurofit tests in European children and adolescents aged 9-17 years.

METHODS:

A systematic review was undertaken to identify papers that explicitly reported descriptive results for at least one of nine Eurofit tests (measuring balance, muscular strength, muscular endurance, muscular power, flexibility, speed, speed-agility and cardiorespiratory fitness (CRF)) on children and adolescents. Data were included on apparently healthy (free from known disease/injury) children and adolescents aged 9-17 years. Following harmonisation for methodological variation where appropriate, pseudodata were generated using Monte Carlo simulation, with population-weighted sex-specific and age-specific normative centiles generated …

Temporal Trends In The Cardiorespiratory Fitness Of Children And Adolescents Representing 19 High-Income And Upper Middle-Income Countries Between 1981 And 2014, Grant Tomkinson, Justin J. Lang, Mark S. Tremblay

Education, Health & Behavior Studies Faculty Publications

Objective To estimate international and national temporal trends in the cardiorespiratory fitness (CRF) of children and adolescents and to examine relationships between temporal trends in CRF and temporal trends in broad socioeconomic and health-related indicators across countries.

Methods Data were obtained from a systematic search of studies that explicitly reported 20 m shuttle run test (a validated measure of CRF) descriptive data on apparently healthy individuals aged 9–17 years. Following the estimation of relative peak oxygen uptake (mL/kg/min) as a measure of CRF, sample-weighted temporal trends were estimated at the country–sex–age level using best-fitting linear or polynomial regression models relating …

Systematic Review Of The Relationship Between 20m Shuttle Run Performance And Health Indicators Among Children And Youth, Justin J. Lang, Kevin Belanger, Veronica Poitras, Ian Janssen, Grant Tomkinson, Mark S. Tremblay

Education, Health & Behavior Studies Faculty Publications

Objective

This systematic review aimed to summarize research that assessed the associations between 20 m shuttle run test (20mSRT) performance and indicators of physiological, psychosocial and cognitive health among school-aged children and youth.

Design

Systematic review.

Methods

Five online databases were used to identify peer-reviewed studies published from 1980 to 2016. Studies were included if they matched these criteria: population (children and youth with a mean age of 5–17 years and/or in Grades 1–12), intervention/exposure (performance on the 20mSRT), and outcomes (health indicators: adiposity, cardiometabolic biomarkers, cognition, mental health, psychosocial health, self-esteem and physical self-perception, quality of life and wellbeing, …

Digit Ratio (2d:4d) And Muscular Strength In Adolescent Boys, Jordan M. Tomkinson, Grant Tomkinson

Education, Health & Behavior Studies Faculty Publications

Using a cross-sectional design, this study quantified the relationship between the digit ratio (2D:4D) and muscular strength in 57 adolescent boys. 2D:4D was very likely a moderate negative correlate of handgrip strength, even after adjustment for age and body size. This result may reflect the organizational benefits of prenatal testosterone.

Review Of Criterion-Referenced Standards For Cardiorespiratory Fitness: What Percentage Of 1 142 026 International Children And Youth Are Apparently Healthy?, Justin J. Lang, Mark S. Tremblay, Francisco B. Ortega, Jonatan R. Ruiz, Grant Tomkinson

Education, Health & Behavior Studies Faculty Publications

Purpose To identify criterion-referenced standards for cardiorespiratory fitness (CRF); to estimate the percentage of children and youth that met each standard; and to discuss strategies to help improve the utility of criterion-referenced standards for population health research.

Methods A search of four databases was undertaken to identify papers that reported criterion-referenced CRF standards for children and youth generated using the receiver operating characteristic curve technique. A pseudo-dataset representing the 20-m shuttle run test performance of 1 142 026 children and youth aged 9–17 years from 50 countries was generated using Monte Carlo simulation. Pseudo-data were used to estimate the international …

Addition Of The Apical Oblique Projection Increases The Detection Of Acute Traumatic Shoulder Abnormalities In Adults, Kimberley J. Ross, Grant Tomkinson, Bonnie F. Mcgregor, Oliver C. Ayres, Diana Piscitelli

Education, Health & Behavior Studies Faculty Publications

Purpose

Plain radiographic evaluation of acute shoulder trauma in adults requires a minimum of two projections, commonly the anteroposterior (AP) and lateral scapular projections, with additional projections taken for diagnosis. The aim of this retrospective study was to determine whether the addition of the apical oblique (AO) projection to the AP and lateral scapular projections increases the number and/or alters the types of abnormalities detected in the examination of acute shoulder trauma.

Methods

Examinations of 56 adults who had undergone three-projection (AP, lateral scapular, AO) radiographic shoulder examination for acute trauma were allocated into two-projection (AP, lateral scapular) and three-projection …

No Effect Of A Whey Growth Factor Extract During Resistance Training On Strength, Body Composition, Or Hypertrophic Gene Expression In Resistance-Trained Young Men, Michael J. Dale, Alison M. Coates, Peter R.C. Howe, Grant Tomkinson, Matthew T. Haren, Andrew Brown, Marissa Caldow, David Cameron-Smith, Jonathan D. Buckley

Growth factors can be isolated from bovine milk to form a whey growth factor extract (WGFE). This study examined whether WGFE promoted activation of the AKT/mTOR pathway enabling increased lean tissue mass and strength in resistance trained men. Forty six men with >6 months of resistance training (RT) experience performed 12 weeks of RT. Participants consumed 20 g/day of whey protein and were randomised to receive either 1.6 g WGFE/day (WGFE; n = 22) or 1.6 g cellulose/day (control, CONT; n = 24). The primary outcome was leg press one-repetition maximum (LP1-RM) which was assessed at baseline, 6 and 12 …
