转型期我国有效体育需求不足问题研究

运用问卷调查及资料分析的方法研究转型期我国有效体育需求发展的水平及社会经济环境。结果表明，转型期虽然我国的有效体育需求水平呈总体上升趋势，但体育消费额占居民收入和消费总支出的比例还很小，整个体育产业对GDP的贡献是很有限的。加快完善社会保障体制的步伐，努力提高低收入者的可支配收入，增强居民的体育消费意识，完善体育市场服务体系，政府运用税收手段调节体育商品供给是提高我国有效体育需求的有效手段。

The Hit & Turn Tennis Test: An acoustically controlled endurance test for tennis players

Abstract

This study was conducted to validate and evaluate the “Hit & Turn Tennis Test”, an acoustically progressive on-court endurance test for tennis players. Ninety-eight competitive tennis players (53 males, 45 females) of different age groups participated in the study. For validation, the adult male players completed three Hit & Turn tests, one on a clay court and two on a carpet surface, a tennis-specific ball machine test and an incremental treadmill run in a randomized order. A stronger correlation between maximal performance (r = 0.81, P < 0.01) and maximal oxygen uptake (r = 0.96, P < 0.01) was observed between the Hit & Turn test and the ball machine test, than between the Hit & Turn test and the treadmill test. For test–retest, we found a significant correlation between maximal performance on the same (r = 0.83, P < 0.01) and on different surfaces (r = 0.74, P < 0.01). During test evaluation, maximal performance was higher in males than in females (P < 0.01) and increased by consecutive age group in boys (P < 0.01) but not in girls (P = 0.97). In conclusion, Hit & Turn maximum test performance can be recommended as a valid and reliable indicator for tennis-specific endurance.     

Physiological and biomechanical responses to walking underwater on a non-motorised treadmill: effects of different exercise intensities and depths in middle-aged healthy women

Abstract

Non-motorised underwater treadmills are commonly used in fitness activities. However, no studies have examined physiological and biomechanical responses of walking on non-motorised treadmills at different intensities and depths. Fifteen middle-aged healthy women underwent two underwater walking tests at two different depths, immersed either up to the xiphoid process (deep water) or the iliac crest (shallow water), at 100, 110, 120, 130 step-per-minute (spm). Oxygen consumption (VO₂), heart rate (HR), blood lactate concentration, perceived exertion and step length were determined. Compared to deep water, walking in shallow water exhibited, at all intensities, significantly higher VO₂ (+13.5%, on average) and HR (+8.1%, on average) responses. Water depth did not influence lactate concentration, whereas perceived exertion was higher in shallow compared to deep water, solely at 120 (+40%) and 130 (+39.4%) spm. Average step length was reduced as the intensity increased (from 100 to 130 spm), irrespective of water depth. Expressed as a percentage of maximum, average VO₂ and HR were: 64–76% of peak VO₂ and 71–90% of maximum HR, respectively at both water depths. Accordingly, this form of exercise can be included in the “vigorous” range of exercise intensity, at any of the step frequencies used in this study.     

Matching of Male and Female Subjects Using VO2 max

Abstract

We compared cardiorespiratory responses to exercise on an underwater treadmill (UTM) and land treadmill (LTM) and derived an equation to estimate oxygen consumption (VO₂) during UTM exercise. Fifty-five men and women completed one LTM and five UTM exercise sessions on separate days. The UTM sessions consisted of chest-deep immersion, with 0, 25, 50, 75, and 100% water-jet resistance. All session treadmill velocities increased every 3 min from 53.6 to 187.8 m·min^-1. Cardiorespiratory responses were similar between LTM and UTM when jet resistance for UTM was ≥ 50%. Using multiple regression analysis, weight-relative VO₂ could be estimated as: VO₂ (mLO₂·kg^-1·min^-1) = 0.19248 · height (cm) + 0.17422 · jet resistance (% max) + 0.14092 · velocity (m·min^-1) - 0.12794 · weight (kg) - 27.82849, R²= .82. Our data indicate that similar LTM and UTM cardiorespiratory responses are achievable, and we provide a reasonable estimate of UTM VO₂.

Conceptualizing an East Asian popular culture

Since the 1980s, popular cultural products have criss‐crossed the national borders of East Asian countries, enabling a discursive construction of an ‘East Asian Popular Culture’ as an object of analysis. The present essay is a preliminary attempt to provide some conceptual and analytic shape to this object, delineated by its three constitutive elements of production, distribution and consumption. Each East Asian location participates in different and unequal levels in each of these component processes. Production can either be located entirely in a single geographic location or, alternatively, each of the necessary constituent sub‐processes can be executed from different locations; preference for either arrangement tends to reflect the relative dominance of the production location in exporting its finished products. Consumption and thus consumers are geographically located within cultural spaces in which they are embedded. Meanings and viewing pleasures are generated within the local cultures of specific audience. Conceptually, among the several possible consumption positions, the one in which an audience watches an imported programme is most intriguing. In this viewing position, differences between the cultures of the location of consumption and that of the production location become most apparent. The audience member has to bring his or her own cultural context to bear on the content of the imported product and read it accordingly. In this sense, the cultural product may be said to have crossed a ‘cultural’ boundary, beyond the simple fact of its having been exported/imported into a different location as an economic activity. Such an audience position requires the consumer to transcend his or her grounded nationality to forge abstract identification with the foreign characters on screen, a foreignness that is, in turn, potentially reabsorbed into an idea of (East) ‘Asia’; a potential ‘East Asian identity’, emerging from consumption of popular cultural products, is thus imaginable.     

The effect of television viewing on ethnic prejudice against immigrants: A study in the Italian context

Television viewers construct many different meanings from the programs they watch. Here, we investigated whether ethnic prejudice is differentially influenced by the genre of television programs in their portrayal of ethnic minorities. We also wanted to determine whether a higher educational level reduces ethnic prejudice and television use. A self-reported questionnaire was administered to 401 Italian adults. Structural equation modeling was used to analyze the relationships between ethnic prejudice and television program contents and educational level. Viewing Reality and Variety Shows was positively related to ethnic prejudice, News and Public Affairs was negatively related, and Films and TV series had no apparent influence on prejudice. Educational level was negatively related to both ethnic prejudice and watching Reality and Variety Shows, and positively related to viewing News and Public Affairs and Films and TV series programs.     

Distinction through visual art

Visual art is one of the fields where, according to Bourdieu, culture is used to reproduce the class structure. Like other items in the cultural repertoire, paintings, as major examples of visual art, imply social divisions in how they are engaged with by artists, critics and audiences. Within the Bourdieusian framework, cultural engagements with paintings are interpreted as indicators of social position, since appreciation depends on a trained capacity in the family and the educational system, which is often inaccessible to less powerful sections of the population. This would imply that the sorts of paintings favoured by working-class people differ from those preferred by the middle or upper classes. More recent studies have contested the view that a gulf exists between the art tastes of different classes in ways that reproduce the class structure. The argument of the omnivore thesis that distinctions between more popular and legitimate tastes have become blurred has predominantly been based on empirical references in the field of music. This article explores this thesis on the basis of data about visual arts in the Cultural Capital and Social Exclusion project. While some differences continue to be connected to social divisions of income, education and occupational groups, important similarities are found across the board, and certain significant differences appear to relate to factors other than social class, such as ethnicity, age and gender. It is also significant that some people appear disconnected from and disinterested in paintings.
