A 6-Week Mindfulness-Acceptance-Commitment Intervention to Improve Professional Ballet Dancers' Psychological States Around Performance.

Mindfulness and acceptance-based approaches have been trialled in professional sport. The present pilot study was a randomized controlled trial with professional ballet dancers investigating the effectiveness of the Mindfulness-Acceptance-Commitment (MAC) approach, developed for athletes, compared to an education program which included topics relevant to ballet and performance. Participants included 16 professional ballet dancers (2 men and 14 women) who were randomly assigned into either the MAC or education group for 1 session per week, for 6 weeks.

Development of complex executive function over childhood: Longitudinal growth curve modeling of performance on the Groton Maze Learning Task.

This longitudinal study modeled children's complex executive function (EF) development using the Groton Maze Learning Task (GMLT). Using a cohort-sequential design, 147 children (61 males, 5.5-11 years) were recruited from six multicultural primary schools in Melbourne and Perth, Australia.

Wellness Monitoring for Professional Ballet Dancers - A Pilot Study.

Self-report wellness measures are used extensively in elite sport as valid indicators of the adaptive responses to training and performance of an athlete. Wellness parameters such as quality and quantity of sleep, muscle soreness, fatigue, and stress are monitored in professional sport via Athlete Management Systems (AMS) and self-report monitoring applications (App). However, the use of a monitoring App specifically for professional classical ballet dancers has not been tested.

Self-Reported Wellness in Training and Performance: A Comparison of Professional Ballet Dancers and Professional Athletes.

Objective: In high-performance sport, the use of self-report measures is expanding. The exploration of wellness states in response to training and performance requires further investigation for professional ballet dancers and athletes. This study therefore aimed to: compare wellness scores between professional ballet dancers and athletes in training and performance; report frequency of self-reported modified participation during training and performance; and report frequency of self-reported inability to participate due to pain and illness in dancers and athletes.

Cognitive and motor function in developmental coordination disorder.

Aim: To analyse the development of motor skill and executive function in school-aged children with and without developmental coordination disorder (DCD).

Method: Using a longitudinal design, 186 children (86 males, 100 females) aged 6 to 11 years at Time 1 were tested over a 2-year period, 52 of whom were diagnosed with DCD at Time 1 (27 males, 25 females; mean age 8y 5mo, SD 1y 6mo) using DSM-5 criteria. The McCarron Assessment of Neuromuscular Development assessed motor status at Time 1 and at 2-year follow-up (Time 2).

Effectiveness and application of an online leadership intervention to promote mental health and reduce depression-related stigma in organizations.

Addressing the stigma of mental illness and its effect in the workplace is a contemporary issue in occupational health. The role of leaders is a vital but relatively unexplored dimension of this phenomenon. This study examined the effectiveness and application of an online intervention to reduce depression-related stigma in organizational leaders.

Coupling of online control and inhibitory systems in children with atypical motor development: A growth curve modelling study.

Introduction: Previous research indicates that children with Developmental Coordination Disorder (DCD) show deficits performing online corrections, an issue exacerbated by adding inhibitory constraints; however, cross-sectional data suggests that these deficits may reduce with age. Using a longitudinal design, the aim of the study presented here was to model the coupling that occurs between inhibitory systems and (predictive) online control in typically developing children (TDC) and in those with Developmental Coordination Disorder (DCD) over an extended period of time, using a framework of interactive specialization. We predicted that TDC would show a non-linear growth pattern, consistent with re-organisation in the coupling during the middle childhood period, while DCD would display a developmental lag.

Coupling online control and inhibitory systems in children with Developmental Coordination Disorder: Goal-directed reaching.

For children with Developmental Coordination Disorder (DCD), the real-time coupling between frontal executive function and online motor control has not been explored despite reported deficits in each domain. The aim of the present study was to investigate how children with DCD enlist online control under task constraints that compel the need for inhibitory control. A total of 129 school children were sampled from mainstream primary schools.

Mild impairments of motor imagery skills in children with DCD.

It has been hypothesized that the underlying mechanism of clumsy motor behaviour in children with Developmental Coordination Disorder (DCD) is caused by a deficit in the internal modelling for motor control. An internal modelling deficit can be shown on a behavioural level by a task that requires motor imagery. Motor imagery skills are suggested to be related to anticipatory action planning, but motor imagery and action planning have not been tested within the same child.

Executive systems constrain the flexibility of online control in children during goal-directed reaching.

We examined the influence of inhibitory load on online motor control in children. A sample of 129 school children was tested: younger, mid-age, and older children. Online control was assessed using a double-step perturbation paradigm across three trail types: non-jump, jump, and anti-jump.

Understanding performance deficits in developmental coordination disorder: a meta-analysis of recent research.

Aim: Developmental coordination disorder (DCD) is a significant disorder of childhood, characterized by core difficulties in learning fine and/or gross motor skills, and the attendant psychosocial problems. The aim of the meta-analysis presented here (the first on DCD since 1998) was to summarize trends in the literature over the past 14 years and to identify and describe the main motor control and cognitive deficits that best discriminate children with DCD from those without.

Method: A systematic review of the literature published between January 1997 and August 2011 was conducted.
