Adaptation of motor control to training and disuse : contribution of muscle synergy analysis and movement variability

The well-known degrees of freedom problem originally introduced by Nikolai Bernstein (1967) results from the high abundance of degrees of freedom in the musculoskeletal system. Such abundance in motor control have two sides: i) because it is unlikely that the Central Nervous System controls each degree of freedom independently, the complexity of the control needs to be reduced, and ii) because there are many options to perform a movement, a repetition of a given movement is never the same. It leads to two main topics in motor control and biomechanics: motor coordination and motor variability. The present thesis aimed to understand how motor systems behave and adapt under specific conditions. This thesis comprises three studies that focused on three topics of major interest in the field of sports sciences and medicine: expertise, injury risk and fatigue. The first study (expertise) has focused on the muscle coordination topic to further investigate the effect of expertise on the muscle synergistic organization, which ultimately may represent the underlying neural strategies. Studies 2 (excessive medial knee displacement) and 3 (fatigue) both aimed to better understand its impact on the dynamic local stability. The main findings of the present thesis suggest: 1) there is a great robustness in muscle synergistic organization between swimmers at different levels of expertise (study 1, chapter II), which ultimately indicate that differences in muscle coordination is mainly explained by peripheral adaptations; 2) injury risk factors such as excessive medial knee displacement (study 2, chapter III) and fatigue (study 3, chapter IV) alter the dynamic local stability of the neuromuscular system towards a more unstable state. This change in dynamic local stability represents a loss of adaptability in the neuromuscular system reducing the flexibility to adapt to a perturbation.

The relationship between perceived training and development and employee retention:the mediating role of work attitudes

This paper considers how utilizing a model of job-related affect can be used to explain the processes through which perceived training and development influence employee retention. We applied Russell’s model of core affect to categorize four different forms of work attitude, and positioned these as mediators of the relationship between perceived training and development and intention to stay. Using data from 1,191 employees across seven organizations, multilevel analyses found that job satisfaction, employee engagement, and change-related anxiety were significantly associated with intention to stay, and fully mediated the relationship between perceived training and development and intention to stay. Contrary to our hypotheses, emotional exhaustion was not significantly associated with intention to stay nor acted as a mediator when the other attitudes were included. These findings show the usefulness of Russell’s model of core affect in explaining the link between training and development and employee retention. Moreover, the findings collectively suggest that studies examining employee retention should include a wider range of work attitudes that highlight pleasant forms of affect.

How are Canadian universities training and supporting undergraduate medical, physiotherapy and occupational students for global health experiences in international low-resource settings?

Abstract : OBJECTIVES : Canadian medical (MD), physiotherapy (PT) and occupational therapy (OT) students increasingly show an interest in global health experiences (GHEs). As certain moral hazards can occur as a result of student GHEs, a growing consensus exists that universities must have an established selection process, in-depth pre-departure training (PDT), adequate onsite supervision and formal debriefing for their students. This study aimed at identifying current practices in Canadian MD, PT and OT programs and discussing areas for improvement by comparing them with recommendations found in the literature. METHODS : Canadian MD, PT and OT programs (n = 45) were invited to answer an online survey about their current practices for GHE support and training. The survey included 24 close-ended questions and 18 open-ended questions. Descriptive statistics and a thematic analysis were performed on the data and results were discussed with recommendations found in the literature. RESULTS : Twenty-three programs responded to the survey. Student selection processes varied across universities; examples included using academic performance, interviews and motivation letters. All but 1 MD program had mandatory PDT; content and teaching formats varied, as did training duration (2-38 hours). All but 1 MD program had onsite supervision; local clinicians were frequently involved. Debriefing, although not systematic, covered similar content; debriefing was variable in duration (1-8 hours). CONCLUSIONS : Many current practices are encouraging but areas for improvement exist. Integrating global health content into the regular curriculum with advanced study option in global health for students participating in GHEs could help universities standardize support and training.

Training and Updating of Education Boards in Indigenous Schools of Rural Areas: Strengthening Local Education Management

Education management in the schools of indigenous rural areas faces a number of difficulties to implement and comply with the guidelines and requirements of the laws related to budgetary management of resources allocated to Education or Administrative Boards. In addition to being located in scattered rural areas, far from the municipal heads and regional offices of the Ministry of Public Education, one of the main obstacles is that all regulations, laws and guidelines are written in Spanish, and there is people, in this indigenous rural communities, who do not speak, write, read or understand this language. This puts them at an enormous disadvantage, which has a direct impact on the indigenous children’s right to education.

Nonfatal heroin overdoses in Queensland, Australia : an analysis of ambulance data

In the past decade, the utilization of ambulance data to inform the prevalence of nonfatal heroin overdose has increased. These data can assist public health policymakers, law enforcement agencies, and health providers in planning and allocating resources. This study examined the 672 ambulance attendances at nonfatal heroin overdoses in Queensland, Australia, in 2000. Gender distribution showed a typical 70/30 male-to-female ratio. An equal number of persons with nonfatal heroin overdose were between 15 and 24 years of age and 25 and 34 years of age. Police were present in only 1 of 6 cases, and 28.1% of patients reported using drugs alone. Ambulance data are proving to be a valuable population-based resource for describing the incidence and characteristics of nonfatal heroin overdose episodes. Future studies could focus on the differences between nonfatal heroin overdose and fatal heroin overdose samples.

The effectiveness of traffic policing in reducing traffic crashes

Many governments throughout the world rely heavily on traffic law enforcement programs to modify driver behaviour and enhance road safety. There are two related functions of traffic law enforcement, apprehension and deterrence, and these are achieved through three processes: the establishment of traffic laws, the policing of those laws, and the application of penalties and sanctions to offenders. Traffic policing programs can vary by visibility (overt or covert) and deployment methods (scheduled and non-scheduled), while sanctions can serve to constrain, deter or reform offending behaviour. This chapter will review the effectiveness of traffic law enforcement strategies from the perspective of a range of high-risk, illegal driving behaviours including drink/drug driving, speeding, seat belt use and red light running. Additionally, this chapter discusses how traffic police are increasingly using technology to enforce traffic laws and thus reduce crashes. The chapter concludes that effective traffic policing involves a range of both overt and covert operations and includes a mix of automatic and more traditional manual enforcement methods. It is important to increase both the perceived and actual risk of detection by ensuring that traffic law enforcement operations are sufficiently intensive, unpredictable in nature and conducted as widely as possible across the road network. A key means of maintaining the unpredictability of operations is through the random deployment of enforcement and/or the random checking of drivers. The impact of traffic enforcement is also heightened when it is supported by public education campaigns. In the future, technological improvements will allow the use of more innovative enforcement strategies. Finally, further research is needed to continue the development of traffic policing approaches and address emerging road safety issues.
