Low back pain (LBP) is a prevalent musculoskeletal disease that affects a large percentage of the working population, including teachers. The World Health Organization has identified the school as an effective environment for improving child health. For this reason, the figure of the teacher is a fundamental piece in the process of knowledge acquisition about postural education and prevention of LBP among schoolchildren. The present study aims to determine the knowledge of postural education and back pain prevention among primary school teachers. This cross-sectional study evaluated 85 primary school teachers from Majorca (Spain), of whom 17.6% were physical education teachers and 82.4% were classroom teachers. The study was based on two different structured and self-administered questionnaires to investigate into specific knowledge about LBP: Low Back Pain Knowledge Questionnaire (LKQ) and COSACUES-AEF Questionnaire. The results demonstrated a lifetime prevalence of LBP of 96.5% with significant differences determined by sex. The knowledge of participants about LBP was 17.3 in LKQ (range scale 0–24) and 4.3 in COSACUES (range scale 1–10). In conclusion, the teachers knowledge is insufficient to carry out an efficient and useful health promotion program among schoolchildren to prevent LBP.

The aim of this study is to rank some features that characterize the psychological dynamics of cooperative team work in order to determine priorities for interventions and formation: leading positive feedback, cooperative manager and collaborative manager features. From a dataset of 20 cooperative sport teams (403 soccer players), the characteristics of the prototypical sports teams are studied using an average Bayesian network (BN) and two special types of BNs, the Bayesian classifiers: naive Bayes (NB) and tree augmented naive Bayes (TAN). BNs are selected as they are able to produce probability estimates rather than predictions. BN results show that the antecessors (the “top” features ranked) are the team members’ expectations and their attraction to the social aspects of the task. The main node is formed by the cooperative behaviors, the consequences ranked at the BN bottom (ratified by the TAN trees and the instantiations made), the roles assigned to the members and their survival inside the same team. These results should help managers to determine contents and priorities when they have to face team-building actions.

The purpose of this study was to examine the effect mediated by self-determined motivation on an athlete’s burnout, anxiety and fear of failure. To this end, the sample group consisting of 235 semi-professional yachtsmen and women was asked to answer four questionnaires which set out to assess each of the study’s variables: Behavioural Regulation in Sport Questionnaire, Performance Failure Appraisal Inventory, Sport Anxiety Scale-2 and Athlete Burnout Questionnaire. The ex-post facto research was designed to analyse a single group based on structural equation modelling (SEM) between the constructs under analysis. The results illustrate that behavioural regulation could be used to positively predict burnout and fear of failure mediated by sport anxiety. Moreover, behavioural regulation has a significant, positive and moderate bearing on burnout and is wholly mediated by sport anxiety. It concludes by underscoring the point that there is no relationship either between behavioural regulation and burnout or between behavioural regulation and fear of failure, unless the athlete in question experiences anxiety.
