#1. One Year Surveillance of Body Mass Index and Cardiorespiratory Fitness in Primary School Children in North West England and the Impact of School Deprivation Level
Steven Mann, Matthew Wade, Michelle Jones, Gavin Sandercock, Chris Beedie, James Steele
Objectives: Cardiorespiratory fitness (CRF) is independently associated with health and academic attainment in childhood and adolescence. Yet overweight/obesity remain the focus in public health policy. Surveillance of BMI and CRF considering school deprivation levels is limited. Therefore, we examined this in English Primary Schools. Methods: Participants (n=409) were students (9-10 years), from 13 schools. BMI and CRF (20 m shuttle-run) were measured at three time-points across the academic year and a fourth after summer recess. Results: BMI z-scores significantly decreased (p = 0.015) from autumn (z = 0.336 [CI 0.212 to 0.460]) to spring (z = 0.252 [CI 0.132 to 0.371]), and then significantly increased (p = 0.010) to summer (z = 0.327 [CI 0.207 to 0.447]). CRF significantly increased (p < 0.001) from autumn (z = 0.091 [CI -0.014 to 0.196]) to spring (z = 0.492 [CI 0.367 to 0.616]), no change (p = 0.308) into summer (z = 0.411 [CI 0.294 to 0.528]), and a significant decrease (p < 0.001) into the following autumn term (z =...

#2. Objectively measured physical activity and sedentary behaviors in a representative sample of Canadian adults with chronic disease(s) : a cross-sectional study
Gabriel Hains-Monfette, Sarah Atoui, Kelsey Needham Dancause, Paquito Bernard
Background: Physical activity and sedentary behaviors are major determinants of quality of life in adults with one or more chronic disease(s). However, there are no Canadian representative population-based studies investigating objectively measured physical activity and sedentary behaviors in adults with and without chronic disease(s). Objective: To compare objectively measured physical activity and sedentary behaviors in a representative sample of Canadian adults with and without chronic disease(s). Methods: Data were obtained from the Canadian Health Measure Survey (CHMS) (2007-2013). Physical activity and sedentary behaviors were measured using accelerometry in Canadians aged between 35 and 79 years. Data are characterized as daily mean time spent in moderate to vigorous physical activity (MVPA), light physical activity (LPA), and sedentary behavior, as well as steps accumulated per day. Chronic diseases (chronic obstructive pulmonary disease, diabetes, heart diseases, cancer) were assessed via self-report diagnostic or...

#3. Daily objective physical activity and sedentary time in adults with COPD using spirometry data from Canadian Measures Health Survey
Paquito Bernard, Gabriel Hains-Monfette, Sarah Atoui, Gregory Moullec
Introduction Chronic obstructive pulmonary disease (COPD) is expected to be the third leading cause of premature death and disability in Canada and around the world by the year 2020. The study aims to compare objective physical activity (PA) and sedentary time in a population-based sample of adults with chronic obstructive pulmonary disease (COPD) and comparison a group, and to investigate whether these behaviors differ according to COPD severity. Methods From the 2007-2013 Canadian Health Measures Survey dataset, accelerometer and pre-bronchodilator spirometry data were available for 6441 participants, aged 35 to 79. Two weighted analyses of covariance were performed with adjustments for age, sex, body mass index, accelerometer wearing time and season, work, smoking (cotinine), education level and income. A set of sensitivity analyses were carried out to examine the possible effect of COPD, and type of control group. Results A cross-sectional weighted analysis indicated that 14,6% of study participants had a measured airflow...

#4. SONNY LISTON AND THE TORN TENDON
Arturo Tozzi
The first Liston-Clay fight in 1964 is still highly debated, because Liston quitted at the end of the sixth round claiming a left shoulder injury. Here we, based on the visual analysis of Sonny’s movements during the sixth round, show how a left shoulder’s rotator cuff tear cannot be the cause of the boxer failing to answer the bell for the seventh round.

#5. The effects of transcranial direct current stimulation on objective and subjective measures of sports performance: a systematic review and meta-analysis.
Darias Holgado, Miguel A. Vadillo, Daniel Sanabria
Objective: To examine the effects of transcranial direct current stimulation (tDCS) on objective and subjective outcomes of sports performance. Design: Systematic review and meta-analysis. Data Sources: A systematic literature search of electronic databases (PubMed, WOS, Scopus, Google Scholar) and reference lists of included articles up to June 2018. Eligibility Criteria: Randomized sham-controlled trial comparing anodal stimulation with a sham condition providing data on objective and subjective outcomes of sports performance. Results: The analysis of effect sizes from 28 studies comprising 419 participants indicated that anodal tDCS had a small but positive effect on performance g = 0.27, 95% CI [0.05, 0.49], z = 2.40, p = 0.016. Effects were not moderated by type of outcome, electrode placement, muscles involved, number of sessions, or intensity and duration of the stimulation. Importantly, the funnel plot showed that, overall, effect sizes tended to be larger in smaller studies with a high standard error....

#6. ‘Why would you referee?’: An {auto}ethnographic account of a football official.
Charles Ing, John P. Mills
Adopting a creative yet novel autoethnographic approach, this study explores the experiences of the first author, a newly qualified footballing official. In doing so, the study provides a first person account to showcase the realities of refereeing whereby adding to a small pool of refereeing literature in the process. That said, in providing an evocative account with a theoretical analysis, the study looks to both showcase and explain the demands associated with the position. Therefore, by constructing the said narratives in an easy to understand manner, the study looks to showcases the challenges associated with officiating to a broad audience. While, the study gives a viable explanation to why many newly qualified referees drop out from the role, the study hopes to inform and subsequently aid aspiring officials in their ongoing development.

#7. Dose response association of objective physical activity with mental health in a representative national sample of adults: a cross-sectional study
Paquito Bernard, Isabelle Doré, Romain Ahmed Jérôme, Gabriel Hains-Monfette, Kingsbury, Catherine Sabiston
Although higher physical activity (PA) levels are associated with better mental health, previous findings about the shape of the dose–response relationship between PA and mental health are inconsistent. Furthermore, this association may differ according to sedentary levels. We investigated the cross-sectional dose-response associations between objectively measured PA and mental health in a representative national sample of adults. We also examined whether sedentary time modified the PA - mental health associations. Based on 2007-2013 Canadian Health Measures Survey data, PA and sedentary time were measured using accelerometry among 8150 participants, aged 20 to 79 years. Generalized additive models with a smooth function were fitted to examine associations between minutes per day of moderate and vigorous PA (MVPA), light PA (LPA), daily steps (combined or not with sedentary time) and self-rated mental health. A significant curvilinear relationship between average daily minutes of MVPA and mental health was observed, with...

#8. Concurrent validity and test-retest reliability of the barbell hip-thrust exercise
Antonio Dello Iacono, Johnny Padulo, Tea Bešlija, Israel Halperin
Purpose: The barbell hip thrust (BHT) exercise is growing in popularity as evident by the large increase in research outputs investigating its utility as a training intervention and a testing tool. The aim of this study was to examine the concurrent validity and test-retest reliability of the BHT for the first time. Methods: To establish concurrent validity, the peak force and power measured with the BHT force-velocity profile test of 49 handball athletes, were correlated with peak concentric force of the knee-flexors and hip-extensors measured with an isokinetic device at two different velocities. Test-retest reliability was established by correlating the peak force and power measured with the BHT force-velocity profile test of 20 handball athletes on two separate days. Results: The relationships between the isokinetic testing scores and the BHT force-velocity profile tests were moderate to strong (Pearson r ranges: 0.45-0.86). Test-retest reliability of the BHT force-velocity profile was very high as shown with intra-class...

#9. Tramadol effects on physical performance and sustained attention during a 20-min indoor cycling time-trial: A randomised controlled trial
Darias Holgado, Thomas Zandonai, Mikel Zabala, James Hopker, Pandelis Perakakis, Antonio Luque-Casado, Luis Ciria Perez, Eduardo Guerra Hernandez, Daniel Sanabria
Objectives: To investigate the effect of tramadol on performance during a 20-min cycling time-trial (Experiment 1), and to test whether sustained attention would be impaired during cycling after tramadol intake (Experiment 2). Design: randomized, double-blind, placebo controlled trial. Methods: In Experiment 1, participants completed a cycling time-trial, 120-min after they ingested either tramadol or placebo. In Experiment 2, participants performed a visual Oddball task during the time-trial. Electroencephalography measures (EEG) were recorded throughout the session. Results: In Experiment 1, average time-trial power output was higher in the tramadol vs. placebo condition (tramadol: 220 watts vs. placebo: 209 watts; p < 0.01). In Experiment 2, no differences between conditions were observed in the average power output (tramadol: 234 watts vs. placebo: 230 watts; p > 0.05). No behavioural differences were found between conditions in the Oddball task. Crucially, the time frequency analysis in Experiment 2 revealed an overall...

#10. Technical-tactical preparation of Austrian judoka at the Austrian national championships and the number of associated injuries
Michael Handler, Markus Moser, Jose Toca-Herrera, Martin Burtscher
Background & study aim The first Austrian Judo championships took place in 1947. Since then there hasn’t been any scientific literature about technical, tactical or physical preparation about the participants. In addition, there hasn’t been any trauma statistics of Austrian tournaments either. Some scientific studies describe Judo associated injuries on Olympic or international level, but how gentle is the “gentle way”? Are there any associations between techniques and injuries? Material & methods In order to perform this research audiovisual records of the “care system” of all medal fights during the Austrian Judo championships of 2014 and 2015 were analyzed. For 2014 the judo associated injuries were classified by video analysis by a medical doctor. For 2015 they were documented by medical doctors who treated the injuries during the competition time (mat doctors). SPSS was used for statistics. The significance level for the difference of the number of medical intervention dependent on the sex of the fighter was...
