OBJECTIVES: To determine if a 4 d period of high carbohydrate intake can supercompensate muscle glycogen and exercise work capacity on back-to-back occasions. DESIGN: Seven trained cyclists (6 male, VO2 peak: 57 ± 4 mL kg-1  min-1 ) completed a 9-d experimental period, consisting of three intermittent exhaustive cycling trials on days 1 (trial 1), 5 (trial 2) and 9 (trial 3). Following trial 1 cyclists were fed a high carbohydrate diet (˜10 g kg-1  day-1 ) for eight days to assess their capacity to repeatedly supercompensate muscle glycogen with 4 d recovery...

OBJECTIVES: Estimates of adults' moderate-to-vigorous physical activity (MVPA) based on self-report are generally higher than estimates derived from criterion measures. This study examines a possible explanation for part of this discrepancy: the cutpoint bias hypothesis. This hypothesis proposes that inter- and intra-individual variability in energy expenditure, combined with the fact that adults perform a high proportion of daily activities at or just above the traditional 3 MET cutpoint, result in systematic over-estimates of MVPA...

OBJECTIVES: Participants of ultramarathon events experience a complex interaction of psychophysiological stressors. Therefore, the purpose of this study was to investigate the role of trait emotional intelligence (trait EI) on mood states and serum cortisol responses to a 80.5km treadmill ultramarathon. DESIGN: Twelve participants completed an 80.5km time-trial on a motorised treadmill in the fastest possible time. METHODS: Participants' trait EI was measured prior to the trial...

OBJECTIVES: Whole body vibrations in alpine skiing are a potential cause for frequent overuse and acute injuries. Therefore, the aim of the study was to investigate the transmissibility of vibrations from the skis to lower back and head. Attention was addressed to distinguish shocks and transient vibrations from long-lasting vibrations. DESIGN: Whole body vibrations were analysed in snow-plough swinging, basic swinging, short swinging and carved turns performed by eight highly skilled skiers...

OBJECTIVES: To assess the effect of mid-flight trunk flexion and extension on the movements of body segments and lower extremity joints and subsequent landing mechanics during a jump-landing task. DESIGN: Participants performed three jump-landing conditions in a randomized order. METHODS: Forty-one participants completed jump-landing trials when performing three different mid-flight trunk motion: reaching forward, reaching up, and reaching backward...

OBJECTIVES: To examine clinical and radiological characteristics of participants with an ankle sprain in general practice, classified into subgroups of a previously described chronic ankle instability (CAI) model. DESIGN: Cross-sectional study. METHODS: 206 participants, who visited their general practitioner with a lateral ankle sprain 6-12 months before inclusion, completed a questionnaire, physical examination, radiography and magnetic resonance imaging...

OBJECTIVES: To quantify and profile the training and match loads of international footballers as they transition from club-to-camp-to-tournament contexts during multiple international tournaments. DESIGN: Retrospective single-cohort observational study. METHODS: External (session duration and count) and internal (session Rating of Perceived Exertion [s-RPE]) load data of all outfield players from the same national team were compared between club, pre-tournament camp and initial tournament phases of 3 recent international competitions...

OBJECTIVES: Many schools internationally are replacing traditional classrooms (TC) with innovative flexible learning spaces (FLS) to improve academic outcomes. Via a stealth approach, there may be additional unintended health benefits if students reduce their total and prolonged sitting. The aim of this study was to compare student sitting patterns between TC and FLS. DESIGN: School-based cross-over trial. METHODS: Students at nine secondary schools (n=191, M age=13...

DESIGN: Descriptive observational study. METHODS: This study reviewed all instances of diagnosed concussions, CIR activations, and match characteristics during the 2014 NRL season. Information pertaining to the use of the CIR was obtained from the league...

OBJECTIVES: CrossFit is an increasingly popular high intensity work out program geared towards high repetition and intensity done in short intervals. Recently, documented cases of rhabdomyolysis (muscle necrosis and extreme muscle breakdown) after CrossFit participation have become increasingly concerning to physicians and participants alike. DESIGN: Retrospective cohort study. METHODS: All patients who presented to the main hospital at a major academic center complaining of an injury sustained performing CrossFit between June 2010 and June 2016 were identified by the key phrases 'CrossFit', 'crossfit', 'Crossfit' or 'cross fit'...

OBJECTIVES: Alpine skiing is one of the most popular recreational winter sports and attracts millions of tourists every year alone in the Alpine region. Several studies highlight the positive effects of alpine skiing as aerobic physical training and isometric muscle activity that is able to increase exercise capacity and reduce cardiovascular risk factors. However, a certain cardiovascular risk mainly related to an abrupt increase of myocardial oxygen consumption during skiing especially in otherwise sedentary subjects and effects of hypoxia in untrained patients have to be acknowledged...

OBJECTIVES: Ski boots are designed to transfer forces from skier to ski. This transfer is among others affected by the flexion stiffness (FS) and so effects safety and skiing performance. Previous studies have used devices with prosthetic legs to evaluate FS, however, influencing factors like the foot and lower leg shape or individual buckle closure are not considered. The purpose of the study was to (i) develop a device to measure the individual flexion stiffness (IFS) of ski boots worn by skiers, to (ii) determine the repeatability of the measurement, and to (iii) compare the IFS with the nominal flex index of the manufacturers...
