Body image as a leisure constraint: Examining the experience of aerobic exercise classes for young women

Abstract

Previous research has shown that women, and especially young women, in this culture experience pressure to be thin. Although considerable research has been directed toward the investigation of body image and its relationship to psychological health and self‐image, the impact of body image on leisure behavior has not been adequately addressed, nor has body image received much attention as a potential leisure constraint. The purpose of this study was to investigate ways in which body image might function as a constraint to young women's participation in aerobic exercise classes. The study used both quantitative and qualitative methods, including a survey of 190 women undergraduate students and in‐depth interviews with a sub‐sample of 11 students. The qualitative data are the main focus of this analysis. The data indicated that body image did not seem to prevent participation or constrain levels of participation in aerobics. Nevertheless, body image concerns were shown to constrain the enjoyment of aerobics as a leisure activity, and this reduction of enjoyment was related to the clothing worn for aerobics and to competition over appearance and body weight among participants. The findings also showed that body image functioned as a constraint into participation in that body‐image‐related concerns were a major motivating factor exerting pressure on young women to participate in aerobics. In sum, the study suggested that body image can constrain leisure in some situations, although it is not a constraint in the traditional sense of preventing participation. The implications of these findings for the conceptualization of leisure constraints were discussed. Furthermore, some practical implications for the provision of aerobics classes were provided.

火电厂烟气脱硝系统性能考核测试实例

＂十二五＂规划中新增了对NOX的减排指标,而燃煤火力发电厂是NOX排放的主要来源,因此,在电力行业实现烟气脱硝对实现NOX减排目标尤为重要。以华润南京化工园热电有限公司#5（1×300MW）机组为例,介绍了烟气脱硝系统性能考核的测试方法 ,结果表明,各测试指标均符合设计要求,并对脱硝系统日常运行、管理和维护提出了建议。     

剩余污泥厌氧消化的试验研究

选取长春市某污水处理厂剩余污泥和处理城市污水的某厌氧反应器中的剩余污泥作为研究对象．在中温（35℃）条件下,进行污泥产气量和MLSS降解速率的对照试验。结果表明,厌氧污泥的产气量、MLSS降解速率均大于好氧污泥．厌氧污泥比好氧污泥更适宜厌氧消化。     

陕西火电企业脱硝电价研究

火电机组的NOx治理,是继火电厂开展脱硫工作后落实科学发展观、改善大气环境质量的又一重大举措,是构建和谐社会、实现人民群众根本利益的内在要求。“十二五”期间,燃煤火电仍将是陕西省的主要能源利用形式,因此防治NOx污染的任务十分艰巨。目前,陕西省已有4家火电企业进行了脱硝设施的建设。由于脱硝设施的建设与运营费用全部由企业自行负担,经营压力增大。通过对陕西省已建脱硝设施电厂的建设与运营情况进行分析,研究脱硝电价政策出台的必要性和紧迫性,并就陕西省脱硝电价政策提出具体、可操作的建议。
