Abstract In this study, we examined the effects of a supervised, heart rate intensity prescribed walking training programme on cardiorespiratory fitness and glycaemic control in people with type 2 diabetes mellitus. After receiving local ethics approval, 27 individuals (21 males, 6 females) with type 2 diabetes were randomly assigned to an experimental (“walking”) or control group. Participants completed a Balke-Ware test to determine peak heart rate, peak oxygen consumption ([Vdot]O2peak), and peak gradient. The walking group then completed a 7-week (four sessions a week) supervised, heart rate prescribed walking training programme, whereas the control group continued daily life. After training, participants completed another Balke-Ware test. Fasting blood glucose and glycosylated haemoglobin were measured at rest. The results showed that walking training elicited 80% (s = 2) of peak heart rate and a rating of perceived exertion of 11 (s = 1). Peak heart rate and [Vdot]O2peak were higher in the walking than in the control group after training (P < 0.05). Based on the peak gradient before training, the respiratory exchange ratio was significantly lower (P < 0.05) and there was a strong trend for [Vdot]O2 (P = 0.09) and heart rate (P = 0.09) to be lower after training at the same gradient in the walking compared with the control group. These improvements increased walking peak gradient by 5 min (s = 4 min) compared with the control (P < 0.05). There was no change in fasting blood glucose or glycosylated haemoglobin after training. Despite no change in glycaemic control, heart rate prescribed walking improved peak and sub-maximal cardiorespiratory responses. The beneficial adaptations support the use of heart rate monitoring during walking in people with type 2 diabetes mellitus. 相似文献

Abstract Inertial sensors may provide the opportunity for broader and more cost effective gait analysis; however some questions remain over their potential use in this capacity. The aim of the study was to determine whether an inertial sensor could discriminate between normal walking, fast walking, and running. A single group crossover design was used to compare acceleration profiles between three gait conditions: normal walking, fast walking, and running. An inertial sensor was placed on the sacrum of 12 participants (6 male, 6 female) who performed 3 trials of each gait condition on both overground and treadmill settings. A significant difference (P < 0.001) in the occurrence of heel strike in the gait cycle was found between running and both walking conditions. No differences were seen between overground and treadmill in any condition or variable. The results indicate that a single sacral mounted inertial sensor can differentiate running from normal walking and fast walking using temporal gait event measures. This study indicates that inertial sensors can differentiate walking from running gait in healthy individuals which may have potential for application in the quantification of physical activity in the health and exercise industry. 相似文献

Understanding what influences an individual to transition from awareness that a sport team exists to attraction to that team is of critical importance in the management and development of consumer bases. Determining the factors that prevent individuals at a stage of awareness from becoming attracted is of equal importance. In this paper we use a social identity approach to explore reasons for non-attendance. Qualitative data were gathered from a mixed-method online survey administered to registered participants in a large football (soccer) association in New South Wales. The questionnaire included an open-ended question allowing individuals who had not attended a match during the previous 12 months to elaborate on the reasons that they did not attend. The seventy-five individuals who responded to this open-ended question comprise the sample for this research. Data highlighted that cognitive apathy and disidentification were both salient cognitive responses associated with individuals who did not attend. Furthermore, club values and characteristics were shown to influence team-based perceptions. The findings present implications for sport teams to overcome cognitive apathy and disidentification through organisation-initiated efforts to disseminate information and promote the team, as well as efforts to align team characteristics and values with consumer perceptions. 相似文献

The authors explored the relationship between counseling trainees' emotional intelligence (EI), empathy, stress, distress, and demographics. Results indicated that higher levels of EI were associated with lower stress and distress, higher affective and cognitive empathy, and age. These findings suggest curricular integration of EI and potential utility of EI measures to evaluate students' progress throughout the program. 相似文献

Unidimensionality and local independence are two common assumptions of item response theory. The former implies that all items measure a common latent trait, while the latter implies that responses are independent, conditional on respondents’ location on the latent trait. Yet, few tests are truly unidimensional. Unmodeled dimensions may result in test items displaying dependencies, which can lead to misestimated parameters and inflated reliability estimates. In this article, we investigate the dimensionality of interim mathematics tests and evaluate the extent to which modeling minor dimensions in the data change model parameter estimates. We found evidence of minor dimensions, but parameter estimates across models were similar. Our results indicate that minor dimensions outside the primary trait have negligible consequences on parameter estimates. This finding was observed despite the ratio of multidimensional to unidimensional items being above previously recommended thresholds. 相似文献

This study sought to address Hofstede and McCrae’s (2004) call for systematic cross-cultural comparisons of trait-like attributes. Specifically, we examined the extent to which Danish, Icelandic, Polish, and American adults’ trait affection given and trait affection received are (a) dependent on national origin, and (b) associated with Hofstede’s dimensions of cultures (i.e. individualism-collectivism, masculinity-femininity, power distance, and uncertainty avoidance). The participants (N = 606) completed a questionnaire in English that consisted of the trait affection given and trait affection received scales. Results of a multivariate analysis of variance and linear regression analyses revealed that people’s trait affection given and received are (a) dependent on national origin, and (b) associated with Hofstede’s dimensions of cultures. 相似文献

Today there is much interest in teaching secondary students about climate change. Much of this effort has focused directly on students’ understanding of climate change. We hypothesize, however, that in order for students to understand climate change they must first understand climate as a system and how changes to this system due to both natural and human influences result in climatic and environmental changes and feedbacks. The purpose of this article is to articulate a climate system framework for teaching about climate change and to stimulate discussion about what secondary students should know and understand about a climate system. We first provide an overview of the research on secondary students’ conceptions of climate and climate change. We then present a climate system framework for teaching about climate and climate change that builds on students’ conceptions and scientific perspectives. We conclude by articulating a draft conceptual progression based on students’ conceptions and our climate system framework as a means to inform curriculum development, instructional design, and future research in climate and environmental education. 相似文献
