Studies included in the analysis (k = 12) were randomised controlled trials investigating the effects of any form...

Introduction Better understanding the psychological consequences of an injury and its influence on behavior changes and the implementation of a prevention program seems relevant for injury management (treatment and prevention). Thus, the objective of this present study was (1) to analyze the perception of injury by athletes, and (2) to analyze the...

Therefore, we aim to provide an overview of the current knowledge about the problem of injuries in Athletics. Main findings: It is necessary to maintain a clear definition of “injury” when stakeholders in Athletics discuss...

While ample research has shown that sport injuries are associated with poor psychological status, scant attention has been given to changes in injured athletes' psychological status over the full course of recovery and return to sport. The aim of the present study was to prospectively investigate potential changes in injured athletes' psychological...

Background Psychological processes have been associated with the risk of sports injury. However, different psychological processes can be related to different injury characteristics based on their modes of onset, severity or number. Objective To cluster injury characteristics and identify the links with psychological processes in elite athletes pr...

Perceptual cognitive skills in real game settings, under conditions of fatigue, such as the ability to gather relevant visual information, are key factors in achieving motor goals in sports. The objectives were to evaluate the effects of acute physical fatigue on gaze behavior during a badminton game (Study 1) and in an unfavorable force ratio situ...

The emotional and eating characteristics of individuals with both obesity and binge eating disorder (BED) and those with obesity without BED have been widely studied. However, it is unclear whether the difficulties of these individuals are attributable to BED or obesity. The principal objective is to compare the emotional difficulties, impulsive tr...

Recent studies suggest that vegetarian diets may be recommended to promote weight loss in individuals living with obesity. However, limited studies have examined psychological factors (e.g., eating styles, impulsivity) among individuals who have adopted this type of diet, even though these factors are known to play a role in being overweight. The p...

This study aimed to explore how stakeholders in athletics perceived the relevance of injury prevention, determine their communication preferences, and describe their expectations regarding injury prevention. We conducted a cross-sectional study using an exploratory online survey with high-level athletes (i.e., listed by the French ministry of sport...

• To individualise injury risk reduction measures could help to better match athlete's individual characteristics and should thus improve their effectiveness. • To individualise injury risk reduction measures could help to improve athlete adherence into such measures and consequently their effectiveness. • This maximised individualised approach is...

In regular times, implementing exercise-based injury prevention programs into the training routine of high-level and professional athletes represents a key and challenging aspect to decrease injury risk. Barriers to implementing such prevention programs have previously been identified such as lack of resources, logistic issues or motivation. The CO...

In badminton, the ability to quickly gather relevant visual information is one of the most important determinants of performance. However, gaze behavior has never been investigated in a real-game setting (with fatigue), nor related to performance. The aim of this study was to evaluate the effect of fatigue on gaze behavior during a badminton game s...

In March 2020, the Your COVID-19 Risk tool was developed in response to the global spread of SARS-CoV-2. The tool is an online resource based on key behavioural evidence-based risk factors related to contracting and spreading SARS-CoV-2. This article describes the development of the tool, the produced resources, the associated open repository, and...

L'Organisation mondiale de la santé (OMS) alerte la population mondiale au sujet du manque d'ac-tivité physique (AP) et présente la sédentarité comme quatrième facteur de risque de décès dans le monde. « Par rapport à des in-dividus moins actifs, les personnes ayant une activité physique régu-lière et suffisante présentent un taux de mortalité infé...

Une activité physique régulière est recommandée à la population générale, mais on peut se demander ce qu’il en est des groupes de personnes ayant des be- soins spécifiques. Moyennant quelques adaptations, l’activité physique serait également profitable à des populations vulnérables, ou des groupes de patients, et notamment les patients atteints de...

Objectives This systematic review and meta-analysis sought to evaluate the efficacy of mindfulness-based programs (MBPs) on eating disorder (ED) symptoms and related outcomes such as BMI, body dissatisfaction, emotion regulation, and negative affect.

Presurgery lifetime exposure to traumatic event, presurgery and postsurgery dysfunctional eating patt...

Le vécu d'événements traumatiques est associé à l'obésité adulte, et cette association s'expliquerait par l'apparition de troubles alimentaires. D'autre part, il semblerait que l'exposition à une expérience traumatique soit associée à des déficits dans la régulation des émotions, eux-mêmes associés à une prévalence plus élevée de troubles alimentai...

Background: The current investigation is the first large-scale population-based study from France that documents the association between excess body weight and common psychiatric disorders, and examines the influence of gender on the association between excess body weight and these disorders.

Physical activity has been shown to reduce anxiety and/or depression levels in patients with chronic physical diseases as well as healthy individuals. Similarly, mindfulness- and acceptance-based interventions have also been shown to reduce levels of anxiety and depression. Furthermore, recent research suggests that mindfulness is also associated w...

La pratique du dressage en vue de la compétition engendre des difficultés qui dépassent les compétences techniques : gestion de sa capacité à mémoriser des mouvements, à se les représenter dans l’espace, à les enchaîner avec un équidé qui peut se comporter parfois très différemment une fois sur le carré par rapport à l’entrainement, imprévus extern...

Background: Passenger air transport has considerably increased in the past 50 yr. It is estimated that between 7 and 40% of the population of industrialized countries is currently afraid of flying. Programs treating the fear of flying have been developed to meet this problem. This study measures the effectiveness of one of these programs by focusi...

Laboratory-based studies in sport science have limited value if they do not faithfully replicate performance levels seen in the natural environment. Vine et al. (2014) demonstrated that in stressful conditions, a modification of the quiet eye is observed commensurate with a performance drop in putting. However, Fournier and Bernier (2013), when com...
