    Self-regulation research analyses behaviour and emotion through goal progress (Carver and Scheier 2013). Goal disengagement is advocated as an adaptive self-regulatory strategy for unattainable goals to reduce distress (Wrosch et al. 2003a; 2003b). In an attempt to further understand ongoing goal pursuit and emotions on endurance athletes, this paper applies adaptive self-regulation theory to interpret and explain the experiences of three cyclists in case studies which display variations in success and failure. Following criterion sampling methods we analysed positive and negative affect, goal expectancy and power output from three male participants (triathletes or cyclists; age range 26-50 yrs) who either successfully achieved their goal (Participant 1), were unsuccessful yet recalculated their goal (Participant 2) or failed to achieve their goal (Participant 3) in a 20 km laboratory cycle time trial. Post trial qualitative data provided explanations regarding pacing, perceptions of achievement and feeling states (self-chosen adjectives). Positive affect tracked goal expectancy with increases in positive affect when power output exceeded previous trial averages and goal expectations were high evidencing successful goal striving (Participant 1). Reductions in positive affect occurred where goal progress was below expectations. This reduction was dramatic in the unsuccessful trial (Participant 3). Low levels of positive affect and high levels of negative affect were reported from 12 – 20 km together with disappointment, unexpected feelings of a loss of control and fatigue, suggesting unsuccessful goal striving. Supporting goal disengagement theory, a relinquishment of goal commitment was evident for participant 2 who recalculated his goal. Despite being unsuccessful in achieving his original goal participant 2 reported positive feeling states and perceptions of control post trial indicating adaptive self-regulation strategies were effective in his specific situation. These findings emphasise the need to examine practical adaptive self-regulation strategies in sport and relationships between affect, decision making and goal striving

    Background Past research on the association between insomnia and suicidal ideation (SI) has produced mixed findings. The current study explored the relationship between insomnia, SI, and past-year mental health status among a large Canadian Forces (CF) sample. Method Data was obtained from the 2013 Canadian Forces Mental Health Survey (CFMHS), and included a large representative sample of Canadian Regular Forces personnel (N = 6700). A series of univariate logistic regressions were conducted to test individual associations between past-year mental health status, insomnia, and potential confounds and SI. Mental health status included three groups: 0, 1, or two or more probable diagnoses of posttraumatic stress disorder (PTSD), major depressive disorder (MDD), generalized anxiety disorder (GAD), panic disorder (PD) and alcohol abuse/dependence. Stepwise multivariate logistic regression was used to assess the relationship between insomnia and SI with mental health status as a moderator. Results 40.8% of respondents reported experiencing insomnia. Both insomnia and number of mental health conditions incrementally increased the risk of SI. However, past-year mental health status was a significant moderator of this relationship, such that for CF personnel with either no (AOR = 1.61, 1.37–1.89) or only one past-year mental health condition (AOR = 1.39, 1.12–1.73), an incremental increase in insomnia was associated with an increased likelihood of SI. However, in personnel with two or more past-year mental health disorders, insomnia was no longer significantly associated with SI (AOR = 1.04, 0.81–1.33). Conclusions Insomnia significantly increased the odds of SI, but only among individuals with no or one mental health condition. Findings highlight the importance of assessing insomnia among CF members in order to further suicide prevention efforts

    Agreed Definitions and a Shared Vision for New Standards in Stroke Recovery Research: The Stroke Recovery and Rehabilitation Roundtable Taskforce

    The first Stroke Recovery and Rehabilitation Roundtable established a game changing set of new standards for stroke recovery research. Common language and definitions were required to develop an agreed framework spanning the four working groups: translation of basic science, biomarkers of stroke recovery, measurement in clinical trials and intervention development and reporting. This paper outlines the working definitions established by our group and an agreed vision for accelerating progress in stroke recovery research

    PURPOSE: The objective of this study is to examine risk taking and risk perception associations with perceived exertion, pacing, and performance in athletes. METHODS: Two experiments were conducted in which risk perception was assessed using the domain-specific risk taking (DOSPERT) scale in 20 novice cyclists (experiment 1) and 32 experienced ultramarathon runners (experiment 2). In experiment 1, participants predicted their pace and then performed a 5-km maximum effort cycling time trial on a calibrated Kingcycle mounted bicycle. Split times and perceived exertion were recorded every kilometer. In experiment 2, each participant predicted their split times before running a 100-km ultramarathon. Split times and perceived exertion were recorded at seven checkpoints. In both experiments, higher and lower risk perception groups were created using median split of DOSPERT scores. RESULTS: In experiment 1, pace during the first kilometer was faster among lower risk perceivers compared with higher risk perceivers (t(18) = 2.0, P = 0.03) and faster among higher risk takers compared with lower risk takers (t(18) = 2.2, P = 0.02). Actual pace was slower than predicted pace during the first kilometer in both the higher risk perceivers (t(9) = -4.2, P = 0.001) and lower risk perceivers (t(9) = -1.8, P = 0.049). In experiment 2, pace during the first 36 km was faster among lower risk perceivers compared with higher risk perceivers (t(16) = 2.0, P = 0.03). Irrespective of risk perception group, actual pace was slower than predicted pace during the first 18 km (t(16) = 8.9, P < 0.001) and from 18 to 36 km (t(16) = 4.0, P < 0.001). In both experiments, there was no difference in performance between higher and lower risk perception groups. CONCLUSIONS: Initial pace is associated with an individual's perception of risk, with low perceptions of risk being associated with a faster starting pace. Large differences between predicted and actual pace suggest that the performance template lacks accuracy, perhaps indicating greater reliance on momentary pacing decisions rather than preplanned strategy.This is the author accepted manuscript.

    Deception studies manipulating centrally acting performance modifiers: a review.

    Athletes anticipatorily set and continuously adjust pacing strategies before and during events to produce optimal performance. Selfregulation ensures maximal effort is exerted in correspondence with the end point of exercise, while preventing physiological changes that are detrimental and disruptive to homeostatic control. The integration of feedforward and feedback information, together with the proposed brain_s performance modifiers is said to be fundamental to this anticipatory and continuous regulation of exercise. The manipulation of central, regulatory internal and external stimuli has been a key focus within deception research, attempting to influence the self-regulation of exercise and induce improvements in performance. Methods of manipulating performance modifiers such as unknown task end point, deceived duration or intensity feedback, self-belief, or previous experience create a challenge within research, as although they contextualize theoretical propositions, there are few ecological and practical approaches which integrate theory with practice. In addition, the different methods and measures demonstrated in manipulation studies have produced inconsistent results. This review examines and critically evaluates the current methods of how specific centrally controlled performance modifiers have been manipulated, within previous deception studies. From the 31 studies reviewed, 10 reported positive effects on performance, encouraging future investigations to explore the mechanisms responsible for influencing pacing and consequently how deceptive approaches can further facilitate performance. The review acts to discuss the use of expectation manipulation not only to examine which methods of deception are successful in facilitating performance but also to understand further the key components used in the regulation of exercise and performance

    Purpose. To understand how athletes invest their energy over a race, differences in pacing ability between athletes with and without intellectual impairment (II) were explored using a novel field test. Methods. Well-trained runners (n=67) participated in this study, including 34 runners with II (age = 24.4 +/- 4.5 years; IQ = 63.1 +/- 7.7) and 33 runners without II (age = 31.4 +/- 11.2 years). The ability to perform at a pre-planned submaximal pace was assessed. Two 400m running trials were performed on an athletics track, with an individually standardized velocity. In the first trial, the speed was imposed by auditory signals given in 20m-40m intervals, in combination with coach-feedback during the initial 200m. The participant was instructed to maintain this velocity without any feedback during the final 200m. In trial 2, no coach-feedback was permitted. Results. Repeated measures analyses revealed a significant between-groups effect. II-runners deviated more from the target time than runners without II. The significant trial x group interaction effect (F = 4.15, p<.05) revealed that the ability to self-regulate the pace during the final 200m improved for runners without II (Trial 1: 1.7 +/- 1.0s, Trial 2: 0.9 +/-0.8s) whereas the II-runners deviated even more in Trial 2 (4.4 +/- 4.3s), than in Trial 1 (3.2 +/- 3.9s). Conclusion. Our findings support the assumption that intellectual capacity is involved in pacing. It is demonstrated that II-runners have difficulties maintaining a preplanned submaximal velocity, and this study contributes to understanding problems II-exercisers might experience when exercising. With this field test, we can assess the impact of II on pacing and performance in individual athletes which will lead to a fair Paralympic classification-procedure
