This study aimed to (1) assess the reliability of the force, velocity, and power output variables measured by a force plate and a linear velocity transducer (LVT) for both the unconstrained and constrained loaded countermovement jump (CMJ), and (2) examine the effect of both the CMJ type and the measurement method on the magnitudes of the same variables. Twenty-three men were tested on the free CMJ and the CMJ constrained by a Smith machine. Maximum values of force, velocity, and power were recorded by a force plate and by a LVT attached to a bar loaded by 17, 30, 45, 60, and 75 kg. The reliability of all mechanical variables proved to be high (ICC > 0.70; CV < 10%) and similar for two CMJ types. However, force plate-derived measures displayed greater reliability than the LVT. The LVT also markedly overestimated the magnitudes of the mechanical variables, particularly at lower external loads. Therefore, although both jump types and both methods could be acceptable for routine testing, we recommend the force platform due to a higher reliability and more accurate magnitudes of the obtained variables. The unconstrained loaded CMJ could also be recommended due to the simpler equipment needed. 相似文献

ABSTRACTThere is currently widespread concern that Britain’s cultural and creative industries (CCIs) are increasingly dominated by the privileged. This stands in stark contrast to dominant policy narratives of the CCIs as meritocratic. Until now this debate has been clouded by a relative paucity of data on class origins. This paper draws on new social origin data from the 2014 Labour Force Survey to provide the first large-scale, representative study of the class composition of Britain’s creative workforce. The analysis demonstrates that CCIs show significant variation in their individual “openness”, although there is a general under-representation of those from working-class origins across the sector. This under-representation is especially pronounced in publishing and music, in contrast to, for example, craft. Moreover, even when those from working-class backgrounds enter certain CCIs, they face a “class origin pay gap” compared to those from privileged backgrounds. The paper discusses how class inequalities, as well as those related to gender and ethnicity, between individual CCIs point to occupational subcultures that resist aggregation into the Department for Culture, Media and Sport’s broader category of CCIs. The paper concludes by suggesting the importance of disaggregating CCIs and rethinking the definition and boundaries of CCIs as a meaningful category. 相似文献
