Context: Explanatory approaches for back pain (BP) in athletes focus on biomechanical factors while neglecting psychological perspectives. Psychological factors have gained importance in the prediction of injuries in athletes and BP in the general population, with stress and recovery emerging as central risk factors. However, scarce evidence exists regarding the role of these aspects for the prevalent burden of BP. Objective: To investigate the association between stress and recovery parameters and the presence of BP. Design: Cross-sectional design. Setting: The questionnaires were distributed after the training sessions. Participants: A total of 345 competitive athletes (mean age = 18.31 y [SD = 5.40]) were investigated. The classification of the athletes' competitive status was based on performance level. Interventions: Data were collected using questionnaires for the assessment of stress, recovery, and BP. Main Outcome Measures: The authors performed a multiple logistic regression to obtain odds ratios for stress and recovery parameters with regard to the outcome variable BP status. Results: For stress, the dimension "overall stress" (odds ratio = 1.83; 95% confidence interval, 1.30–2.59; P =.001) and the scale "physical complaints" (odds ratio = 1.68; 95% confidence interval, 1.25–2.25; P =.001) of the general version of the Recovery-Stress Questionnaire resulted to be significantly associated with BP. None of the recovery-related scales displayed a statistically significant relationship with BP. Conclusion: The outcomes of this study imply a modest association between stress and the presence of BP in competitive athletes. Practitioners may take these findings into account regarding the conception of training and for monitoring purposes. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this systematic review was to identify sources of stress, consequences of chronic stress and moderators of stress in physical education teachers and to formulate implications for future research and teacher education. Methods: The initial search identified 2483 publications, including 47 that met the inclusion criteria. Results: The most important sources of stress in physical education teachers were the curriculum, inadequate facilities/equipment, the low status of PE and students´ discipline problems. Regarding the consequences of chronic stress, the majority of studies assessed burnout and reported low to moderate levels of burnout in general. However, of the studies that reported percentages, 20-25% of physical education teachers indicated high levels of burnout. Conclusions: Regarding the relationship between sources of stress and consequences of chronic stress in physical education teachers, future studies should (a) take into account the whole stress process (b) use more adequate measures for stress and (c) address potential moderators of stress. In terms of practical implications, PE teachers should receive an adequate pre- and in-service training that aims at being aware of the main sources of stress in PE teachers and building up adequate coping strategies. In addition, PE teacher education should consider interventions to prevent health consequences of stress such as voice disorders. [ABSTRACT FROM AUTHOR]

Back pain (BP), a prominent problem for competitive athletes, is a primary reason for limitations in athletic performance and daily life restrictions. As studies on the relationship between psychological variables and BP in athletes are scarce, the aim of this study was to investigate stress and depression in competitive athletes with BP. In a cross-sectional design, data of 154 competitive athletes (51% female; Mage = 18.81 years, SDage = 5.05 years) were collected, assessing Performance stress, Socio-emotional stress, Risk for depression and Psychological well-being and the two BP parameters BP Intensity and Disability. Two multiple linear regressions were conducted to predict (1) BP Intensity and (2) Disability from Performance stress, Socio-emotional stress, Risk for depression and Psychological well-being. Multiple linear regressions demonstrated that Performance stress (β = .21, p = .01) was the only significant predictor of BP Intensity (F1,142 = 6.68, p = .01, R2 = .05), whilst Risk for depression (β = .24, p = .01) was the only significant predictor of Disability (F1,142 = 8.46, p = .01, R2 = .06). Neither gender nor age explained a significant amount of variance in the models. Study results showed that, as in the general population, the variables stress and depression are related to BP in competitive athletes. In particular, BP intensity was found to be associated with stress and BP-related disability was associated with depression, whereas age and gender showed no association with the BP parameters. A longitudinal investigation is warranted to determine the direction of the observed relationships. [ABSTRACT FROM AUTHOR]

Abstract: Background: Recovery describes a restoring process influencing the health conditions of individuals but a potential link to low back pain (LBP) has not been scrutinized so far. Psychological strategies to deal with LBP have been considered within the biopsychosocial approach but substantial evidence regarding specific psychological underpinnings remains elusive. The current study aimed to compare individuals with different recovery–stress patterns (i.e. specific combinations of recovery/stress) regarding their pain and disability in the lower back. Methods: Cross‐sectional data from 265 physically active individuals with non‐specific LBP were collected via standardized questionnaires. The participants engaged in prescribed exercise therapy provided by a healthcare professional owing to their back burden. A k‐means cluster analysis identified three clusters. Results: Cluster 1 entailed individuals with high recovery and low stress values, Cluster 2 represented participants with medium scores on both dimensions and Cluster 3 included participants with low recovery and high stress values. The statistical analyses for pain intensity using analyses of covariance indicated significantly higher values for Cluster 3 compared with Clusters 1 and 2 for worst pain intensity (p < 0.001 and p = 0.003, respectively) and mean pain intensity (p < 0.001 and p = 0.001, respectively). The disability comparisons using non‐parametric tests showed significantly higher LBP‐related disability in Cluster 3 than Cluster 1 on two disability measures. Conclusions: The findings indicate an association between detrimental recovery–stress patterns and LBP. Examining the role of recovery has innovative practical relevance for LBP prevention and rehabilitation through the implementation of approaches to enhance recovery in relevant programmes.

Health issues represent a frequent problem for athletes, as this particular demographic is repeatedly confronted with physically and psychologically stressful situations. Back pain (BP) materialises as comparatively common health problem being regarded as functionally limiting and psychologically straining burden for athletes. According to research conducted on athletes with BP, biomechanical and physiological mechanisms emerge as influential, whereas stress-related psychological factors appear to be neglected. For athletic injuries, the essential impact of psychological processes on injury occurrence and return from injury has already been corroborated. Hence, the aim of this literature review is to: (1) introduce a conceptual differentiation between injuries and BP; (2) summarise the results obtained regarding stress-related psychological aspects for injuries; and (3) connect the injury research to the state-of-the-art evidence regarding stress-related factors for BP among athletes. A distinction between injuries and BP could be established based on previous definitions, despite the fact that a considerable overlap between both concepts prevails. Injuries can be attributed to a physical origin, whereas BP frequently lacks this physical criterion. For BP, our enquiry yielded four studies including psychological measures of stress – with two studies specifically examining the association between BP and psychological stress among athletes longitudinally. Abundant findings from the general population support the importance of considering psychological and specifically stress-related factors in BP prevention and rehabilitation, but evidence related to the athletic field remains elusive. Further scientific investigations with a wider methodological approach are needed to deepen the knowledge about the crucial relationship between psychological stress, BP, and athletes.

Objective In the general population, physical and mental stress factors are linked to chronic low back pain (LBP). The aim of the present study was to examine this association among athletes. Design Longitudinal study with a six-month interval between measurements. Setting Questionnaires were filled out at home, either in paper–pencil version or online. Participants Eighty-two male and 57 female athletes ( N = 139, M Age = 32.24) who exercise on a competitive ( n = 102) or recreational level ( n = 37), with a weekly training volume of at least 3 h. Main outcome measures At T 0 , stress parameters were assessed via the Recovery-Stress Questionnaire (RESTQ-Basic-48) and the Screening Scale of the Trier Inventory for the Assessment of Chronic Stress (TICS-SSCS). At T 0 and T 1 , different chronification indicators were measured. Based on these assessments, the sample was split into a chronification and no-chronification group. Results ANCOVAs were used to conduct group comparisons with regard to stress levels. The chronification groups showed higher stress values for all chronification indicators. For the variables Physical Complaints and Overall Stress-TICS , the group differences became significant ( p < .05). Conclusion A relationship between stress parameters and LBP chronification was demonstrated among athletes for the first time. [ABSTRACT FROM AUTHOR]

Athletes’ precompetitive appraisal determines which emotion they experience with regard to an upcoming competition. Such precompetitive emotions have powerful and potentially destructive consequences for performance. To control and optimise these consequences, it is important to examine precompetitive appraisal. Currently, such efforts are hampered by the lack of a valid measurement tool. The present study aimed to develop a novel measure of precompetitive appraisal. Specifically, the Precompetitive Appraisal Measure (PAM) was constructed by adapting an existing self-report scale. Female and male intercollegiate team sport athletes (N = 384) completed the PAM, along with a measure of intensity and interpretation of precompetitive anxiety symptoms (CSAI-2D) prior to competition. On these responses, (a) a Principal Component Analysis and a Confirmatory Factor Analysis supported the PAM’s suggested two-factor structure (Primary and Secondary Appraisal), (b) cluster analyses indicated the measure’s ability to distinguish theoretically congruent appraisal profiles (Threat and Challenge) and (c) a MANOVA and multiple regression analyses demonstrated that PAM-responses predicted precompetitive symptom intensity and interpretation. Further, analyses revealed that the majority of athletes appraised the upcoming competition as a challenge. [ABSTRACT FROM PUBLISHER]

Previous findings of decreased mental and perceptual motor performance during parabolic flights have been attributed mainly to the primary effects of weightlessness rather than the accompanying effects of stress and altered mood. Although recent studies have alluded to the possible negative effects of stress on performance, there has been no attempt to investigate this during parabolic flights. Over a period of 3 years, 27 human participants (male n = 18, mean age ± SD 34.67 ± 7.59 years; female n = 9, 36.22 ± 9.92 years) were recruited with the aim to evaluate if, and to what extent, parabolic flights are accompanied by changes in mood. Furthermore, the relationships between mood and physiological markers of stress and arousal, namely circulating stress hormones (ACTH, cortisol, epinephrine, norepinephrine, prolactin and brain activity (EEG)) were investigated. A strong and significant correlation was found between circulating stress hormone concentrations and perceived physical state, motivational state (MOT) and psychological strain (PSYCHO), whereas no interaction between mood and EEG or EEG and stress hormone concentrations was observed. Therefore, two different stress responses appear to be present during parabolic flight. The first seems to be characterised by general cortical arousal, whereas the second seems to evolve from the adrenomedullary system. It is likely that both these mechanisms have different effects on mental and perceptual motor performance, which require further investigation and should to be taken into account when interpreting previous weightlessness research.

It has been suggested that the central and peripheral neural processes (CPNP) are affected by gravitational changes. Based on the previous experiments during parabolic flights, central and peripheral changes may not only be due to the changed gravitational forces but also due to neuroendocrine reactions related to the psycho-physiological consequences of gravitational changes. The present study focuses on the interaction of neuroendocrine changes and the physical and mental states after acceleration to three-time terrestrial gravity (3Gz). Eleven participants (29.4 ± 5.1 [SD] years (male (n = 8): 30 ± 5.1 years; female (n = 3): 27.7 ± 2.1 years) underwent a 15 min acceleration to 3Gz in a human centrifuge. Before and after the acceleration to 3Gz circulating stress hormone concentrations (cortisol, adrenocorticotropic hormone (ACTH), prolactin, epinephrine, norepinephrine) and perceived physical and mental states were recorded. A second control group of 11 participants underwent the same testing procedure in a laboratory session. Serum cortisol concentration during exposure to the centrifugal acceleration increased by 70%, plasma concentration of ACTH increased threefold, prolactin twofold, epinephrine by 70% and norepinephrine by 45%, whereas the perceived physical well-being decreased. These findings demonstrate that psycho-physiological changes have to be regarded as a relevant factor for the changes in CPNP during phases of hypergravity exposure. [ABSTRACT FROM AUTHOR]

In this introductional contribution, (1) model-theoretical backgrounds and directions of the actual approaches in sport injury research are clarified, (2) the resulting criteria and research desiderata are summarized, and (3) conclusions and perspectives for future research are outlined. Emphasis is given to trait and interactional concepts and approaches derived and closely linked to stress research. Considering the process of recovery and the reinjury phenomenon, various aspects are discussed, which have been neglected or have not been integrated in conceptualizations on injury until now. The action-theory perspective is outlined and suggested to build a framework for a more sophisticated approach. Following this model, it is recommended to focus more on process analyses and also to refer to single case studies in future research on sports injuries. [ABSTRACT FROM AUTHOR]
