Objectives:To establish injury rates among a population of elite athletes, to provide normative data for psychological variables hypothesised to be predictive of sport injuries, and to establish relations between measures of mood, perceived life stress, and injury characteristics as a precursor to introducing a psychological intervention to ameliorate the injury problem.Methods:As part of annual screening procedures, athletes at the Queensland Academy of Sport report medical and psychological status. Data from 845 screenings (433 female and 412 male athletes) were reviewed. Population specific tables of normative data were established for the Brunel mood scale and the perceived stress scale.Results:About 67% of athletes were injured each year, and about 18% were injured at the time of screening. Fifty percent of variance in stress scores could be predicted from mood scores, especially for vigour, depression, and tension. Mood and stress scores collectively had significant utility in predicting injury characteristics. Injury status (current, healed, no injury) was correctly classified with 39% accuracy, and back pain with 48% accuracy. Among a subset of 233 uninjured athletes (116 female and 117 male), five mood dimensions (anger, confusion, fatigue, tension, depression) were significantly related to orthopaedic incidents over the preceding 12 months, with each mood dimension explaining 6–7% of the variance. No sex differences in these relations were found.Conclusions:The findings support suggestions that psychological measures have utility in predicting athletic injury, although the relatively modest explained variance highlights the need to also include underlying physiological indicators of allostatic load, such as stress hormones, in predictive models.

Dance-based interventions have been proposed for the management of Parkinson's disease (PD) symptoms. This review critically appraises and synthesises the research on the effects of dance interventions on gait, cognition and dual-tasking in PD, through a meta-analysis of peer-reviewed literature from seven databases. Eligible studies included people with PD, used a parallel-group or cohort design with a dance-based intervention, reported outcome measures of gait, cognition or dual-tasking, and were published in English up until September 2017. Of the initial 1079 articles, 677 articles were reviewed for eligibility, and 25 articles were retained. Only 12 articles had sufficient common assessment items for meta-analysis. Two independent reviewers extracted the data and assessed the risk of bias of each study using the Cochrane risk-of-bias tool. Based on pre-post change scores, gait speed, Timed Up and Go (TUG) test performance, freezing of gait questionnaire, and six-minute walk test times significantly improved after a dance intervention compared to controls. Global cognition assessed with Montreal Cognitive Assessment, and cognitive dual-tasking measured using dual-task TUG, also exhibited greater improvement in dance groups. There was limited evidence to determine the most effective intensity, frequency, duration of dance interventions or the most beneficial music. Findings must be interpreted cautiously because of the lack of randomised control trials, and the moderate to high risk of bias of studies. However, the results of papers with level-I and level-II.1 evidence suggest that dance may have the potential to ameliorate PD symptoms, particularly gait, global cognition and cognitive dual-tasking.

BACKGROUND: While dance may improve motor features in Parkinson’s disease (PD), it is not yet clear if the benefits extend to non-motor features. OBJECTIVE: To determine whether dance classes based on Dance for PD ® , improve cognition, psychological

Strategies for addressing anxiety-related decrements in performance have been implemented across a variety of domains, including Sex, Sport, and Stage. In this review, we (1) iterate the dominant anxiety-related remediation strategies within each of these domains; (2) identify over-lapping and domain-specific strategies; and (3) attempt to unify the conceptualization of performance-related anxiety across these three areas under the information-processing framework of the Reflective/deliberative—Impulsive/automatic Model (RIM). Despite both diversity and similarity in remediation approaches across domains, we found that many strategies appear to share the common goal of maintaining a dominant automatic style of information processing in high performance demand situations. We then describe how various remediation strategies might hypothetically fit within the RIM framework and its subcomponents, identifying each intervention as falling into one or more broad categories related to achieving and/or maintaining dominance in automatic information processing. We conclude by affirming the benefit of adopting a unifying information-processing framework for the conceptualization of performance-related anxiety, as a way of both guiding future cross- and inter- disciplinary research and elucidating effective remediation models that share common pathways/mechanisms to improved performance.

Professional dance careers require years of intensive training. Stress experienced during training must be balanced with adequate recovery to prevent overtraining and burnout. Little is known, however, about how dancers achieve recovery–stress balance. This study examined dancers’ recollection of stress and recovery during their vocational dance training to identify potential stressors and recovery behaviors in vocational dance training. Twelve current and ex-professional ballet (n=4) and contemporary dancers (n=8) participated in the study. Four general dimensions, based on the extant overtraining literature in athletes, were identified: dance culture, intrapersonal, interpersonal, and situational factors. Cultural norms, health factors related to injury and illness, and transition periods within vocational dance training were sources of stress for participants. Dancers’ responses to stress were categorized as adaptive or maladaptive. Maladaptive behavioral responses (e.g., ignoring injury, pain, and fatigue) were related to negative training outcomes associated with overtraining and burnout. Interventions that encourage adaptive behaviors for dance students to support health and well-being are recommended to address the recovery–stress balance in vocational dance training identified in this study.

This systematic review examines the relationship between injury and two stages of a dancer's career development: when transitioning to full-time training and to a professional dance company. The findings are discussed in relation to managing transitioning loads with regard to injury prevention. Six electronic databases (PubMed, Embase, CINAHL, SPORTDiscus, Scopus, and Performing Arts Periodicals Database) were searched from inception to July 2018, inclusive of English language peer reviewed studies investigating injury in pre-professional and professional ballet and contemporary dancers. Seventeen studies met the inclusion criteria. “Limited” evidence revealed that dancers transitioning to professional ballet had a significantly higher rate of time-loss injuries per exposure hour relative to established professionals, whereas transitioning professional contemporary dancers had a significantly lower rate of both medical-attention and time-loss injuries. “Limited” evidence also showed a decreased rate and trend toward lower prevalence rates for time-loss injuries per exposure hour for transitioning ballet students and an increased rate of medical-attention injury in a combined cohort of transitioning ballet and contemporary dance students. Thus, this review provides some evidence that injuries tend to occur as dancers are transitioning to full-time ballet or contemporary dance training or to professional careers.
