In-depth interviews were conducted with 16 men who had a significant other who had given birth within the last 5 years. Men were asked about their perceptions of pregnancy-related weight gain, and content analysis was used to identify themes from the interviews. Men described nine themes related to perinatal weight gain: (a) negative perceptions, (b) eating behaviors, (c) exercise habits, (d) health impact, (e) body changes, (f) weight-loss success, (g) “it bothered her more than me,” (h) “the weight gain wasn’t a problem,” and (i) intimacy. Together, these themes offer a glimpse into men’s experiences and highlight the discord and balance between experiencing negative feelings/perceptions and being a supportive partner. This information on how men perceive pregnancy-related weight gain can be used to develop interventions to assist men to support their significant others in meeting weight loss goals following pregnancy.  相似文献

School-based management (SBM) is a standard feature of many current reforms. While previous research found that poorly designed and poorly implemented SBM had few positive effects, recent research suggests that SBM can improve instructional programs and produce higher levels of student learning. This article synthesizes research findings from major studies of SBM to identify the core elements of a successful SBM strategy. By comparing schools that successfully used SBM with schools that struggled to implement SBM, we generate 8 elements of schooling that were associated with successful SBM. In brief, these elements address vision, decision-making authority, power, knowledge and skills, information, rewards, leadership, and resources.  相似文献

Abstract

The present experiment evaluated the effects of a 27-day sit up exercise training program on adipose cell size and adiposity. Fat biopsies were taken from the abdomen, subscapular, and gluteal sites by needle aspiration in 13 experimental and 6 control male subjects before and after a five days/week progressive training regimen. Day 1 consisted of 10 bouts of 10-sec exercise, 7 sit ups/bout, with 10-sec rest intervals; on day 27, 14 bouts of 30-sec exercise were performed, 24 sit ups/bout with 10-sec rest intervals. The total number of sit ups done was 5004. Fat cells were isolated using collagenase and photographed to determine cell diameter. Repeated measures ANOVA revealed significant decreases in cell diameter at the three biopsy sites (p<.01), but no significant differences in the rate of change (pre to post) in cell diameter between sites for the experimental and control groups (p>.05). Body weight, total body fat (underwater weighing), and fatfolds and girths remained unaltered. The results demonstrate that (1) the conventional sit up exercise does not preferentially reduce adipose cell size or subcutaneous fat thickness in the abdominal region to a greater extent compared to other adipose sites, and (2) significant changes in fat cell size may occur in the absence of changes in fatfolds, girths or total body composition.  相似文献
