This study was designed to examine the magnitude and duration of excess postexercise oxygen consumption (EPOC) following upper body exercise, using lower body exercise for comparison. On separate days and in a counterbalanced order, eight subjects (four male and four female) performed a 20-min exercise at 60% of mode-specific peak oxygen uptake (VO2) using an arm crank and cycle ergometer. Prior to each exercise, baseline VO2 and heart rate (HR) were measured during the final 15 min of a 45-min seated rest. VO2 and HR were measured continuously during the postexercise period until baseline VO2 was reestablished. No significant difference between the two experimental conditions was found for magnitude of EPOC (t [7] = 0.69, p greater than .05). Mean (+/- SD) values were 9.2 +/- 3.3 and 10.4 +/- 5.8 kcal for the arm crank and cycle ergometer exercises, respectively. Duration of EPOC was relatively short and not significantly different (t [7] = 0.24, p greater than .05) between the upper body (22.9 +/- 13.7 min) and lower body (24.2 +/- 19.4 min) exercises. Within the framework of the chosen exercise conditions, these results suggest EPOC may be related primarily to the relative metabolic rate of the active musculature, as opposed to the absolute exercise VO2 or quantity of active muscle mass associated with these two types of exercise.  相似文献

Engagement in problem‐solving and mathematical discussion is critical for learning mathematics. This research review describes a gap in the literature surrounding engagement of students with Learning Disabilities in standards‐based mathematical classrooms. Taking a sociocultural view of engagement as participation in mathematical practices, this review found that students with LD were supported towards equal engagement in standards‐based mathematics through multi‐modal curriculum, consistent routines for problem‐solving, and teachers trained in Mathematical Knowledge for Teaching. Using this small set of studies (7), we identify the need to deepen the engagement of students with LD in mathematical problem‐solving and discussion. This review concludes with implications for teaching and learning.  相似文献

One important socio-cultural medium through which young children’s moral understanding is cultivated is parent/child discourse. Of particular interest to us was young children’s use of basic (‘thin’) evaluative concepts (good, bad, right and wrong), which are ubiquitous in everyday discourse and serve as a potential bridge from the non-moral to the moral domain. We investigated 14 2–5-year-old children’s (and their parents’) use of thin evaluative concepts and found that while they frequently used good and bad to morally evaluate other people’s and their own psychological/dispositional states and behaviors—as well as, less frequently, to highlight relevant standards, expectations and rules—they did not use right and wrong. In contrast, a sample of US written and spoken public conversation revealed that adults did. Reasons for this are discussed, along with the frequency of different types of moral evaluations, differences between children and their parents, and age-related trends.  相似文献

Adapted from Chang et al.'s (2006) models, this study examines factors that influence adoption and non-adoption of social network sites (SNS) in adopters (Continuers, Discontinuers) and non-adopters (Potentials, Resistors). Chi-square and t-test were used to analyze the survey data of Singapore's working adults and Internet users (N =222). The findings reveal innovation characteristics (relative advantage, compatibility, complexity) and perceived popularity differ significantly in three pairs of adopter categories. Results show Continuers and Potentials are concerned more about image than Discontinuers and Resistors, while technology cluster differs between adopter vs. non-adopter and Continuers vs. Discontinuers. Moreover, the study suggests younger people tend to adopt SNSs, females continue to use SNSs more, and potential SNS users are more innovative. Lastly, a regression model to forecast the adoption of SNSs is proposed in which age, compatibility, technology cluster, and perceived popularity are predictors.  相似文献

Across the literature, travelling has been viewed as a recurring activity for older adults and is driven by a multitude of purposes and reasons. Previous studies have probed touristic activities of older adults however, little is known about their emotional experiences specifically their sense of happiness when joining international group tours, hence this phenomenological study. A qualitative approach was utilized to gather data from a group of 15 purposively selected participants aged 60 years and above. A two-part instrument consisting of a robotfoto and a semi-structured interview was used in this study. Through vertical and horizontal analyses of the field text, this study afforded the development of The Spiraling Model of Aging Filipino Tourists’ Happiness. This model describes aging tourists’ happiness while travelling as a product of Shared Moments, Shared Culture, Shared Memories, and Shared Transcendence. Summarily, findings of this study may provide significant insights to service providers such as hotels, airlines and travel agencies across the globe in developing innovative marketing strategies that cater to this promising age group. Empirically, this study may stimulate further exploration in the field of Cognitive Psychology aimed at adding large-scale data regarding the study of emotions specifically older adults’ happiness when joining international group tours.  相似文献

The purpose of this study was to examine the relation between the ability to quickly acquire initial mental graphemic representations (MGRs) in kindergarten and fourth grade literacy skills in children with typical language (TL) and children with language impairment (LI). The study is a longitudinal extension of a study conducted by Wolter and Apel in which kindergarten children with LI and TL were administered early literacy measures as well as a novel written pseudoword task of MGR learning (spelling and identification of target pseudowords). In the current study (4 years later), the authors administered reading and spelling measures to 37 of the original 45 children (18 children with LI, 19 children with TL). The children with LI performed significantly lower than their peers with TL on all fourth grade literacy measures. For both groups, kindergarten initial MGR acquisition ability significantly related to fourth grade real-word reading and spelling. For the children with LI, kindergarten initial MGR acquisition ability also related to fourth grade pseudoword decoding and reading comprehension. Collectively, the findings suggest that initial MGR learning in kindergarten is an essential skill that may uniquely relate to later literacy abilities.  相似文献

The aim of this study was to understand the relationships between self‐compassion, positive affect, negative affect, and variables representative of positive body image for college women. Regression analyses indicated that self‐compassion and affect accounted for 39% and 30% of the variance, respectively, in body appreciation and body image quality of life. Mediational analyses demonstrated that positive affect mediated the relationships between self‐compassion and both indicators of body image. Implications for college counseling are discussed.  相似文献

Abstract

This study was designed to examine the magnitude and duration of excess postexercise oxygen consumption (EPOC) following upper body exercise, using lower body exercise for comparison. On separate days and in a counterbalanced order, eight subjects (four male and four female) performed a 20-min exercise at 60% of mode-specific peak oxygen uptake (VO2) using an arm crank and cycle ergometer. Prior to each exercise, baseline VO2 and heart rate (HR) were measured during the final 15 min of a 45-min seated rest. VO2 and HR were measured continuously during the postexercise period until baseline VO2 was reestablished. No significant difference between the two experimental conditions was found for magnitude of EPOC (t [7] = 0.69, p > .05). Mean (± SD) values were 9.2 ± 3.3 and 10.4 ± 5.8 kcal for the arm crank and cycle ergometer exercises, respectively. Duration of EPOC was relatively short and not significantly different (t [7] = 0.24, p > .05) between the upper body (22.9 ± 13.7 min) and lower body (24.2 ± 19.4 min) exercises. Within the framework of the chosen exercise conditions, these results suggest EPOC may be related primarily to the relative metabolic rate of the active musculature, as opposed to the absolute exercise VO2 or quantity of active muscle mass associated with these two types of exercise.  相似文献
