The evidence base pointing towards the maladaptive health consequences of an inactive lifestyle highlights the need for interventions that are effective in changing and maintaining physical activity behaviours. Theories of motivation are frequently applied to inform the content and delivery of such interventions. Systematic monitoring and evaluation of the quality of intervention implementation is therefore an important step in understanding if and how theories of motivation can be adopted and effectively applied to promote and/or sustain physical activity behaviours. However, intervention implementation quality in studies that aim to apply motivation theory to promote physical activity is often under-reported. The purpose of this article is, first, to review contemporary approaches used to monitor and evaluate intervention implementation; we outline the degree to which these methods have been used effectively in research concerned with applying theories of motivation to impact physical activity behaviours. Second, we identify and discuss specific challenges in effectively measuring quality of implementation faced by researchers who adopt a motivation theory basis to their work. Finally, recommendations for methods to monitor and evaluate intervention implementation in future trials aiming to promote physical activity based on theories of motivation are also proposed.  相似文献   

Long-term endurance training increases serum cathepsin S and decreases IL-6 and hsCRP levels

Cathepsin S (CS) was shown to play a key role in cancer progression, atherosclerosis, heart valve disease, insulin resistance and diabetes mellitus. The present prospective study aimed to investigate the influence of sports on CS, interleukin-6 (Il-6) and high-sensitivity C-reactive protein (hsCRP) levels.

Ninety-eight of 109 participants completed the study. Ergometries were performed at baseline and after 8 months to evaluate/quantify the performance gain. Blood samples were taken at baseline and every 2 months. CS was measured by ELISA (enzyme-linked immunosorbent assay). Compared to the control group (mean performance gain ?3.41 ± 4.62%) we observed a significant physical-activity-induced increase of CS levels (3.45–3.73 ng · ml^?1; P = 0.027) and a significant decrease of Il-6 (2.43–1.91 pg · ml^?1; P = 0.031) and hsCRP-levels (0.11–0.09 mg · dl^?1; P = 0.001) in the intervention group (mean performance gain: 12.13 ± 6.32%). Furthermore, the tendency of the progression was significant for CS and Il-6 (P = 0.002/0.033).

We could show a significant sports-induced decrease of the classic inflammation parameters hsCRP/Il-6, probably expressing a downregulation of permanently prevalent inflammation processes. Simultaneously CS levels increased significantly. Our results show that increasing CS amounts are not simply to equal with an enhanced inflammation status and might even have beneficial effects on inflammation and angiogenesis.  相似文献   

Postpartum Mothers’ Leisure-Time Exercise Behavior is Linked to Positive Emotion During Partner Discussions     

Rachel L. Hutt  Ginger A. Moore  Micah A. Mammen  Danielle Symons Downs 《Research quarterly for exercise and sport》2017,88(4):447-454

Purpose: Marital dissatisfaction and conflict often increase for couples after the birth of a child and are evident in fewer positive family interactions and more negative family interactions. Because exercise is known to increase positive emotions and decrease negative emotions, the current study examined the extent to which higher levels of mothers’ exercise during the postpartum period were related to more positive and fewer negative emotion-expressive behaviors with their infants’ fathers. Method: Mothers’ (N = 46; M = 8 months postpartum) positive and negative expressive behaviors were coded during couples’ discussions of current conflict and positive family experiences. Mothers self-reported their leisure-time exercise behavior. Results: First-time mothers and mothers with higher levels of leisure-time exercise behavior displayed higher levels of positive expressive behaviors during couples’ discussions. Conclusions: Exercise may be associated with increased positive emotion and, in turn, can have great potential to improve family relationships during the postpartum period when marital stress normatively increases, particularly for mothers with more than 1 child. Future longitudinal studies are needed to understand exercise patterns across the postpartum period to identify the most effective timing and optimal level of exercise that lead to more positive expressive behaviors.  相似文献

艺术的情境之寓——文艺美学探微     

宋生贵 《广播电视大学学报》2007,(2):56-59

情境者,情趣境界之谓也,主于美。它存在于艺术作品中,也存在于整个艺术审美活动中。艺术没有唯一的和绝对的摹本,也没有终级价值标准,有的便是一件件具体的作品和一次次具体的活动。一件作品就是一个独绝的情境,这情境是别人创造不出的,甚至创造者自己都是不能重复的。在此情境中,包括每一个细部,即使如绘画中的一处空白,音乐中的一个休止,小说中的一段铺垫,等等,便有着特别的意味,特别的美质。  相似文献

论文学功能系统与特质   总被引：1，自引：0，他引：1  

金雅 《河南师范大学学报(哲学社会科学版)》2002,29(6):83-87

传统的作品功能观把本视为学功能的发生源，把读视为学功能作用的被动对象，本提出：学功能必须在具体的学活动中才能产生，学活动是学功能的发生源。学功能联系于学活动的动态开放整体的流程，并对投身于学活动的一切实践主体（作与读）产生系统效能，学功能系统由认知，净化，愉悦，生命四个各具丰富内涵的子系统构成，并通过系统质的审美化合指向人本身，指向人自身的丰富与完善，指向人的诗意人生，因此，学功能是学之人学本义的回归。  相似文献
