Professor Alan Warde 《Cultural Trends》2006,15(2-3):107-122
It is not unusual now to talk about the culture of the body, or to see routine and organized physical activity, as well as sport, as part and parcel of cultural life. In recent decades body management techniques have become a very conspicuous aspect of self-presentation and have been served by the expansion of the supply of commercial services to deal with diet and health, physical training and cosmetic improvement to appearances. The professionalization and commercialization of sport have also accelerated. Bourdieu interpreted measures for body management and maintenance in terms of the accumulation and display of cultural capital. He distinguished three types of cultural capital: institutionalized, objectified and embodied. This article considers some of the elements of the very complex and extensive property, embodied cultural capital. The Cultural Capital and Social Exclusion (CCSE) survey included questions on sporting activity, sports spectatorship and physical exercise routines, important elements in the mosaic of contemporary cultural activities. This article teases out the patterns of participation and taste in this area, examining differentiation by class, gender, education, ethnic and age groups in particular. While showing that all these factors matter, gender is the most important source of differentiation, though this is more the case for sport than for exercise per se. In addition, it is shown that educational qualification is particularly important in predicting participation in exercise, whereas occupational class makes more difference to the choice of sport, whether playing or watching. 相似文献

Measurement of ground reaction force (GRF) in running provides a direct indication of the loads to which the body is subjected
at each foot-ground contact, and can provide an objective explanation for performance outcomes. Traditionally, the collection
of three orthogonal component GRF data in running requires an athlete to complete a series of return loops along a laboratory
based runway, within which a force platform is embedded, in order to collect data from a discrete footfall. The major disadvantages
associated with this GRF data collection methodology include the inability to assess multiple consecutive foot contacts and
the fact that measurements are typically confined to the laboratory. The objective of this research was to investigate the
potential for wearable instrumentation to be employed, in conjunction with artificial neural network (ANN) and multiple linear
regression (MLR) models, for the estimation of GRF in middle distance running. A modular wearable data acquisition system
was developed to acquire in-shoe force (ISF) data. Matched data sets from wearable instrumentation (source data) and force
plate (target data) records were collected from elite middle-distance runners under controlled laboratory conditions for the
purposes of ANN and MLR model development (MD) and model validation (MV).
In terms of statistical measures of prediction accuracy the MLR model was found to provide a superior level of accuracy for
the prediction of the vertical and medio-lateral components of GRF and alternatively, the ANN model provided the most accurate
predictions of the anterior-posterior component of GRF. The prediction accuracy of each component of GRF was found to be governed
by the inherent signal variability, in which case the vertical and anterior-posterior components were more reliable and subsequently
predicted significantly more accurately than the medio-lateral component.
The emerging capability for obtaining continuous GRF records from wearable instrumentation has the potential to permit unprecedented
quantification of training stress and competition demands in running. 相似文献

目前关于体育教学实习成绩的评定,各院校做法不一,还没有定论。但就目前各校的评估量表看,普遍较复杂,计算量大,指标多,内容不具体,因而不适用。而且对体育教学大都只重视一次公开课或检查课,对平时课堂教学不大重视。因此,制定出客观、全面、简便易行的评估指标体系就具有很重要的意义。 相似文献

Desiring to give those of our readers who may not have heard the broadcast the opportunity of reading so clear a statement
of such a large phase of astronomical research by so eminent an authority, we asked and were readily granted permission to
reprint the text. Possibly those who did hear the broadcast will, like ourselves, welcome the privilege of reading and studying
it at leisure. We therefore, present it here with much satisfaction. 相似文献
