Imagery and self-efficacy in the injury context

ObjectivesTo develop and test the factorial validity of an adapted version of the Athletic Injury Imagery Questionnaire (AIIQ-2: Sordoni, Hall, & Forwell, 2002). To explore the effect of an imagery intervention on self-efficacy in the sport injury context.DesignStudy 1, cross-sectional; Study 2, multiple-base line.MethodIn Study 1 the AIIQ-2 was adapted to include a pain management subscale. This adapted imagery questionnaire (AIIQ-3) was then administered to 291 injured athletes (M age = 28.64 years, SD = 14.30). In Study 2 using a multiple-baseline single subject design, the effects of an imagery intervention on self-efficacy prior to physiotherapy treatment of five athletes with a Type B malleolar fracture (M age = 49.50 years, SD = 16.56) was examined. A follow-up post-experimental interview explored participants' perceptions of the intervention.ResultsStudy 1, confirmatory factor analysis revealed evidence for the factorial validity of the AIIQ-3. Study 2, results from the multiple-base line design demonstrated that for two out of the five participants there were observable and statistically meaningful increases in task efficacy, with the same result in three out of five participants for coping efficacy. The post-interview results revealed that all intervention participants perceived the intervention to be beneficial and effective beyond the general information provided.ConclusionsThe results are discussed in terms of overcoming an inherent weakness in previous injury-related imagery research and the applied implications for the time-course of rehabilitation.     

Performance slumps in sport: A systematic review

This systematic review explored the under-researched experience of performance slumps in sport with four objectives: (i) review definitions of a performance slump; (ii) identify known causes of a performance slump; (iii) identify the symptoms athletes present when in a performance slump; and (iv) review approaches used to combat a slump in performance. Literature searches into three databases (PsychARTICLES, PsychINFO and SPORTDiscus) resulted in the inclusion of quantitative (n = 14) and qualitative (n = 4) empirical research studies. The findings were thematically analysed and narratively synthesised. Results showed that: (i) definitions of a performance slump vary; (ii) perceived expectations for success and athletes attributing poor performance to something about themselves have been empirically verified as performance slump causes; (iii) during a slump, athletes might display a range of emotional and psychological symptoms and/or adopt skill-focused attention; and (iv) athletes reported several ways of coping with a performance slump, and research has offered succeeding under pressure as a potential route out of a slump. This systematic review highlights the need for an empirical investigation of the performance slump phenomenon. Future studies should be directed towards understanding the prominent symptoms athletes experience during the slump, so that cause, context, competitor and symptomatic dependant intervention strategies can be designed.     

Non-instrumental roles of science

Nowadays, science is treated an instrument of policy, serving the material interests of government and commerce. Traditionally, however, it also has important non-instrumental social functions, such as the creation of critical scenarios and world pictures, the stimulation of rational attitudes, and the production of enlightened practitioners and independent experts. The transition from academic to 'post-academic' science threatens the performance of these functions, which are inconsistent with strictly instrumental modes of knowledge production. In particular, expert objectivity is negated by entanglement with political and commercial interests. We cannot go back to the old academic model for science, but need to consider how to maintain its vital non-instrumental roles.

What is an expert?

Experts play an important role in society, but there has been little investigation about the nature of expertise. I argue that there are two kinds of experts: those whose expertise is a function of what theyknow (epistemic expertise), or what theydo (performative expertise). Epistemic expertise is the capacity to provide strong justifications for a range of propositions in a domain, while performative expertise is the capacity to perform a skill well according to the rules and virtues of a practice. Both epistemic and performative experts may legitimately disagree with one another, and the two senses are conceptually and logically distinct.     

Gritting One’s way to success – Grit explains skill in elite youth soccer players beyond (deliberate) practice

Practice is one of the most important predictors of skill. To become an expert, performers must engage in practice for a prolonged time to develop the psychological characteristics necessary for outstanding performance. Deliberate practice (DP), that is focused repetitive activities with corrective feedback, is particularly beneficial for skill development. The amount of accumulated DP differentiates experts and novices. However, the predictive strength of DP weakens considerably when it comes to differentiating between differently skilled experts, leaving a way clear for other non-practice related factors to exercise their influence. In this paper, we demonstrate using a large sample (388) of elite youth soccer players that one such factor, the personality trait of grit, predicts expertise level both directly and indirectly. Grittier players accumulated more time in coach-led team practice, the activity, which is arguably closest to DP in team sports, which in turn predicted the skill level. Other practice activities, such as self-led training or playing with peers, were not predictive of skill level, neither were they influenced by grit. Grit, however, continued to exert a direct positive influence on the skill level of players even after accounting for the hours of DP accumulated. Overall, a standard deviation of change in the grit score resulted in at least a third of standard deviation improvement in skill. Our findings highlight the need for the inclusion of additional factors in theoretical frameworks in situations where the predictive power of traditional expertise factors, such as practice, is limited.     

Macronutrient intake as a prospective predictor of depressive symptom severity: An exploratory study with adolescent elite athletes

BackgroundAppropriate availability of macro- and micronutrients has an important impact on cognitive performance, mood and mental health. Although the critical role of nutrition for elite athletes’ performance was recognized early on, little is known about whether consumption of specific macronutrients (carbohydrates, proteins, fat) predict the development of future depressive symptoms in adolescent elite athletes.MethodsParticipants were recruited from three Swiss Olympic Partner Schools (SOPS) in the Northwestern German speaking part of Switzerland. A total of 97 adolescent elite athletes (38% girls, M_age = 16.35 ± 1.19) participated in the study. Depressive symptoms (PHQ9) were assessed at baseline and after 10 months follow-up. A 3-day food recall was completed three months after the baseline assessment. Linear regression analyses were used to examine whether macronutrients predict depression symptom severity after controlling for covariates and baseline depressive symptoms.ResultsHigher protein consumption in athletes was a prospective predictor of lower depressive symptom severity at follow-up (β = −35, p < .05). Several deviations from recommended nutritional standards were observed in elite athletes.ConclusionsThe findings of this exploratory study support the notion that dietary behaviour may be prospectively associated with athletes’ mental health. However, more research is required with larger samples and more in-depth assessment techniques. Future research should also examine whether nutrition education and dietary modification can be used to prevent depressive symptoms among adolescent elite athletes.
