OBJECTIVES: Overtraining syndrome (OTS) leads to worsened sports performance and fatigue. The pathophysiology of OTS has not been entirely elucidated, and there is a lack of accurate markers for its diagnosis. Changes in hormonal responses implicated in OTS were stimulated by exercise, which has limited their interpretation. Hence, we aimed to evaluate growth hormone (GH) and prolactin responses to a gold-standard and exercise-independent stimulation test, the insulin tolerance test (ITT)...

OBJECTIVES: The risk of metabolic and cardiovascular disease may be reduced by a healthy pattern of daily physical activity. We investigated the feasibility and preliminary effectiveness of advice-based interventions aiming at either increasing moderate-to-vigorous intensity physical activity (MVPA) or reducing sedentary time (ST) in obese volunteers. DESIGN: Randomized non-blinded two-armed trial. METHOD: Inactive, obese adults were randomly assigned to reduce sedentary behavior (SitLess) (n=30) or increase MVPA (ExMore) (n=29) for 4 weeks...

OBJECTIVES: To quantify the magnitude, frequency, duration and distribution of head impact exposure in a women's rugby league competition. DESIGN: Prospective cohort study. METHODS: Twenty-one players had a wireless impact measuring device (X2Biosystems XPatch) behind their right ear during match participation. Head impact data were collected and downloaded for analysis. Median peak linear and rotational accelerations and impact locations between player positions were assessed using a Friedman repeated measures ANOVA on ranks with a Wilcoxon signed-rank test for post hoc analysis with a Bonferroni correction...

OBJECTIVES: Quantifying individual risk for medial tibial stress syndrome (MTSS) is valuable due to the high prevalence, substantial financial and service costs, and lengthy recovery time of the condition. Identification of those at risk is a key first step in prevention of the condition. This study aimed to test a suite of best evidence risk factors in a cohort of Navy recruits and to develop a predictive model for individuals at risk of MTSS. DESIGN: Prospective cohort study of Navy recruits undergoing initial training METHODS: A prospective cohort design, this study screened recruits by assessing gender, MTSS history, years of running experience, orthotic use, BMI, navicular drop, ankle plantarflexion and hip external rotation at the beginning of basic training...

OBJECTIVES: The aim was to examine the associations between level of physical activity (PA) and non-hospital medical costs, and between physical activity and hospitalisations in older women from 1999 to 2013. DESIGN: Longitudinal observational study. METHODS: Data were collected from participants in the Australian Longitudinal Study on Women's Health, who completed surveys in 1999 (aged 73-78 years), 2002, 2005, 2008 and 2011.

OBJECTIVES: The tackle event in rugby union ('rugby') contributes to the majority of players' injuries. Referees can reduce this risk by sanctioning dangerous tackles. A study in elite adult rugby suggests that referees only sanction a minority of illegal tackles. The aim of this study was to assess if this finding was similar in youth community rugby. DESIGN: Observational study. METHODS: Using EncodePro, 99 South African Rugby Union U18 Youth Week tournament matches were coded between 2011 and 2015...

OBJECTIVES: To develop a time-based model of injury-burden for international rugby sevens teams and to demonstrate its utility. DESIGN: Descriptive, cohort study. METHODS: Injury data recorded during seven seasons of the Sevens World Series were used to quantify the rate of injury and the rate at which injured players recovered from injury. An equation describing the rate at which injuries were sustained was combined with an equation for the rate at which injured players recovered from injury to produce a time-based equation for the injury-burden of rugby sevens players at any point in time during a season...
