Altering torsional stiffness of cycling shoe soles may be a novel approach to reducing knee joint moments and overuse injuries during cycling. We set out to determine if the magnitude of three-dimensional knee moments were different between cycling shoe soles with different torsional stiffnesses. Eight trained male cyclists cycled at 90% lactate threshold power output in one of two cycling shoe conditions in a randomized crossover design. The shoe sole was considered torsionally flexible (FLEX) compared to a relatively stiffer (STIFF) sole. Gross efficiency (GE) and knee joint moments were quantified. No significant effect of shoe condition was seen in GE (21.4 ± 1.1% and 20.9 ± 1.6% for FLEX and STIFF, respectively, P = 0.12), nor in three-dimensional knee moments. 4 of the 8 subjects had reduced knee moments in at least 2 of the 3 moment directions. These “responders” were significantly shorter (1.73 ± 0.02 m vs 1.81 ± 0.04 m, P = 0.017) and had a higher relative maximal aerobic power (MAP) (4.6 ± 0.3 W?kg-1 vs 3.9 ± 0.3 W?kg-1, P = 0.024) compared to non-responders. These results suggest that certain shoe characteristics may influence certain individuals differently because these participants belong to different “functional groups”; certain individuals may respond positively to FLEX, while others may not. Further studies should test this proposed hypothesis. 相似文献

Scotland, traditionally, has high levels of confidence in teachers. Fairness and justice are key concepts in policy and practice in Scottish education. For more than 100 years, the high-stakes assessment system in Scotland, with the Scottish Higher qualification at its heart, has been crucial to that sense of opportunity and justice. However, in 2019–2020, public confidence in high-stakes assessment in Scotland, as in other United Kingdom countries, was dented. In Scotland, the Covid-19 pandemic meant that schools were closed, teachers provided online learning opportunities for pupils working at home and, for the first time in 130 years, it was not possible to run national examinations. To ensure that learners were not further disadvantaged, alternative approaches to gathering evidence for qualifications were instigated. However, these results were challenged as socially unjust and the results that had been nationally moderated were replaced by results based on locally moderated teachers' professional judgement. As Scotland looks to qualifications beyond Covid-19, trust must be re-built. This article reports on a participative research project that sought to understand public perceptions of standards and fairness across a range of key communities following this experience. Drawing on both qualitative and quantitative data, we analyse factors which affected trust in National Qualifications under the pandemic. The evidence suggests that when considering what matters for qualifications to be trusted, technocratic solutions are likely to be rejected by stakeholders. Understanding and responding to what led to the mistrust of qualifications in Scotland will be crucial to inform its future qualifications system. 相似文献

This investigation examined the impact of organizational culture on job satisfaction and intention to leave the organization through a survey of fitness staff. Organizational culture is commonly known as the values, beliefs and basic assumptions that help guide and coordinate member behaviour. The Cultural Index for Fitness Organizations (CIFO) was developed to measure organizational culture in the fitness industry specifically. Exploratory factor analysis revealed eight factors that represent cultural dimensions common to this context: staff competency, atmosphere, connectedness, formalization, sales, service-equipment, service-programs, and organizational presence. Path analysis was used to examine the relationship among the organizational culture factors, job satisfaction and intention to leave. Results produced a partially mediated model of organizational culture that explained 14.3% of the variance in job satisfaction and 50.3% of the variance with intention to leave the organization. The findings highlight the multidimensionality of organizational culture and its complexity in the fitness industry. 相似文献

The purpose of this study was to uncover the values of the Commonwealth Games Association's of Canada's international sport and development (IDS) initiative. Interviews were conducted with 39 key program stakeholders (e.g., IDS organizational leaders, host organizational leaders, intern alumni) involved in the management and operations of the initiative. Certain values were espoused by the organization through written documentation while others were perceived by stakeholders and were described as instrumental toward achieving desired end-states. In general, evidence of both congruent and incongruent values emerged through interview data. Nuance between stakeholder groups was also found, which in turn exposed areas of operations requiring further managerial attention. The complex interplay of values uncovered in this study contributes to the research on values in sport management and the emergent area of using sport as a means toward various developmental goals. 相似文献
