DESIGN: Cross-over randomised trial. METHODS: Thirteen healthy participants (16.4±1.3years) completed a four-treatment cross-over trial: (1) uninterrupted sitting+high-energy diet; (2) sitting with breaks+high-energy diet; (3) uninterrupted sitting+standard-energy diet; and (4) sitting with breaks+standard-energy diet...

OBJECTIVES: In thermoneutral conditions, half-time is associated with reductions in body temperature that acutely impair performance. This laboratory-based study compared active, passive, and combined methods of half-time heat maintenance. DESIGN: Randomised, counterbalanced, cross-over. METHODS: After a standardised warm-up (WU) and 15min of rest, professional Rugby Union players (n=20) completed a repeated sprint test (RSSA1). Throughout a simulated half-time (temperature: 20...

OBJECTIVES: To examine the effects of match-related and individual player characteristics on activity profile and technical performance during rotations in professional Australian football. DESIGN: Longitudinal observational study. METHODS: Global positioning system data and player rating scores were collected from 33 professional Australian football players during 15 Australian football League matches. Player rating scores were time aligned with their relative total and high-speed running (HSR) distance (>20kmh(-1)) for each on ground rotation...

OBJECTIVES: The Y Balance Test is one of the most commonly used dynamic balance assessments, providing an insight into the integration of the sensorimotor subsystems. In recent times, there has been an increase in interest surrounding it's use in various clinical populations demonstrating alterations in motor function. Therefore, it is important to examine the effect physiological influences such as fatigue play in dynamic postural control, and establish a timeframe for its recovery. DESIGN: Descriptive laboratory study...

OBJECTIVES: This preliminary study examined whether implicit doping attitude, explicit doping attitude, or both, predicted athletes' vigilance towards unintentional doping. DESIGN: A cross-sectional correlational design. METHODS: Australian athletes (N=143;Mage=18.13, SD=4.63) completed measures of implicit doping attitude (brief single-category implicit association test), explicit doping attitude (Performance Enhancement Attitude Scale), avoidance of unintentional doping (Self-Reported Treatment Adherence Scale), and behavioural vigilance task of unintentional doping (reading the ingredients of an unfamiliar food product)...

OBJECTIVES: Approximately 70% of anterior cruciate ligament (ACL) injuries occur in non-contact situations during cutting and landing maneuvers. Parameters such as footstrike patterns and trunk orientation were found to influence ACL relevant knee loading, however, the relationship between the whole body movement and injury risk is debated. This study identifies whole body movement strategies that increase injury risk, and provides training recommendations to reduce this risk or enable a save return to sports after injury...

OBJECTIVES: To examine different timeframes for calculating acute to chronic workload ratio (ACWR) and whether this variable is associated with intrinsic injury risk in elite Australian football players. DESIGN: Prospective cohort study. METHODS: Internal (session rating of perceived exertion: sRPE) and external (GPS distance and sprint distance) workload and injury data were collected from 70 players from one AFL club over 4 seasons. Various acute (1-2 weeks) and chronic (3-8 weeks) timeframes were used to calculate ACWRs: these and chronic load categories were then analysed to determine the injury risk in the subsequent month...

OBJECTIVES: This study examined the existence of a threshold level (proficiency barrier) of actual motor competence (MC) below which a child is not likely to attain 60min of moderate-to-vigorous physical activity (MVPA) per day. DESIGN: A cross-sectional study. METHODS: Actual MC was assessed in 326 children (48.5% boys; age=9.50±1.24years) using the Test of Gross Motor Development-2; MVPA was measured with ActiGraph GT3X+accelerometers. Perceived MC, included as a potential mediating variable, was assessed with the Self-Perception Profile for Children...

OBJECTIVES: This study investigated the association between high-speed running (HSR) and sprint running (SR) and injuries within elite soccer players. The impact of intermittent aerobic fitness as measured by the end speed of the 30-15 intermittent fitness test (30-15VIFT) and high chronic workloads (average 21-day) as potential mediators of injury risk were also investigated. DESIGN: Observational Cohort Study. METHODS: 37 elite soccer players from one elite squad were involved in a one-season study...

OBJECTIVES: Patients with femoroacetabular impingement (FAI) experience hip pain as well as decreased function and lowered quality of life. The aim was to compare maximal isometric and isokinetic muscle strength (MVC) during hip flexion and extension and rate of force development (RFD) during extension between patients with FAI and a matched reference group. Secondary, the aim was to compare patient hips and subgroups defined by gender and age as well as to investigate associations between hip muscle strength and self-reported outcomes...

OBJECTIVES: The purpose of this study was to examine the match-to-match variation of match-running in elite female soccer players utilising GPS, using full-match and rolling period analyses. DESIGN: Longitudinal study. METHODS: Elite female soccer players (n=45) from the same national team were observed during 55 international fixtures across 5 years (2012-2016). Data was analysed using a custom built MS Excel spreadsheet as full-matches and using a rolling 5-min analysis period, for all players who played 90-min matches (files=172)...

OBJECTIVES: To investigate the influence of BMX helmets and neck braces on translational and rotational accelerations in youth riders. DESIGN: Mixed model, repeated measure and correlation. METHODS: Twenty three competitive youth BMX riders classified by age group (6-9 years, 10-13 years and 14-18 years) completed 6 laps of an indoor BMX track at race pace, 3 laps without a neck brace (NB) and 3 without brace (WB). A triaxial accelerometer with gyroscope was placed behind the right ear to determine the mean number of accelerations, translational and rotational, of the head between conditions and by age group...

OBJECTIVES: To examine isometric hip strength in those with and without CAI, and determine the degree of Star Excursion Balance Test (SEBT) variance explained by isometric hip strength. DESIGN: Single-blinded, cross-sectional, case-control study. METHODS: Thirty individuals with CAI, 29 lateral ankle sprain (LAS) copers, and 26 healthy controls participated. We assessed dynamic postural control with the SEBT anterior (SEBT-ANT), posteromedial (SEBT-PM), and posterolateral (SEBT-PL) reaches, and isometric hip extension (EXT), abduction (ABD) and external rotation (ER) strength with hand-held dynamometry...

OBJECTIVES: Ankle sprains due to landing on an opponent's foot are common in basketball. There is no analysis to date that provides a quantification of this injury mechanism. The aim of this study was to quantify the kinematics of this specific injury mechanism and relate this to lateral ankle ligament biomechanics. DESIGN: Case series. METHODS: The model-based image-matching technique was used to quantify calcaneo-fibular-talar kinematics during four ankle inversion sprain injury incidents in televised NBA basketball games...

Helder Miguel Fernandes
OBJECTIVES: Previous studies have indicated that only a small proportion of Portuguese adolescents attain sufficient levels of physical activity for health. However, it is unknown whether the levels of moderate to vigorous physical activity (MVPA) have changed over a considerable time period in this country. Therefore, the aims of the present study were to examine the 10-year trend changes in self-reported MVPA among adolescents and also investigate differences by sex and age. DESIGN AND METHOD: This study compared two cross-sectional cohorts of youngsters aged 12-18 years, recruited in 2006 (N=1010; 461 boys and 549 girls) and in 2016 (N=1096; 461 boys and 635 girls), using identical procedures and instruments...

OBJECTIVES: The use of interactive video gaming, known as 'exergames' or 'active video games (AVG)' may provide an opportunity for motor skill development. Youth with non-typical patterns of development may have deficits in gross motor skill capacities and are therefore an intervention target. The aim was to determine the effectiveness of AVG use on motor skill development in non-typically developing children and adolescents. DESIGN: Review article. METHODS: The PRISMA protocol was used to conduct a systematic review of EBSCOhost, Embase, Gale Cengage, Informit, Ovid, ProQuest, PubMed, Scopus and Web of Science databases...
