There is inconclusive evidence concerning the effects of routine participation in ultra-endurance events on cardiovascular disease (CVD) risk. Arterial compliance is a reliable, non-invasive, and effective tool for evaluating CVD risk. The purpose of this research was to examine if race length influences acute changes in arterial compliance following an ultra-marathon event. A total of 46 ultra-marathon runners were recruited including 21 participants (39.8?±?8.3?years, 6 females) in the 80-km event and 25 participants (43.7?±?9.8?years, 3 female) in the 195-km event. Arterial compliance was measured via radial applanation tonometry (CR-2000, HDI) for diastolic pulse contour analysis before and following the race. Significant between-group differences were found for changes in large arterial compliance with a decrease (increase in stiffness) following the 195-km event and an increase following the 80-kilometre event (p?<?.05). Longer race lengths are associated with greater reductions in large arterial compliance following recreational ultra-marathon running. Assessment of arterial compliance might be a useful prognostic tool to assess the long-term risk of CVD among ultra-marathon runners.  相似文献   

Temporal trends in 6-minute walking distance for older Japanese adults between 1998 and 2017

BackgroundThe 6-minute walking distance (6MWD) is an excellent measure of both functional endurance and health. The primary aim of this study was to estimate temporal trends in 6MWD for older Japanese adults between 1998 and 2017; the secondary aim was to estimate concurrent trends in body size (i.e., height and mass) and self-reported participation in exercise/sport.MethodsAdults aged 65–79 years were included. Annual nationally representative 6MWD data (n = 103,505) for the entire period were obtained from the Japanese Ministry of Education, Culture, Sports, Science and Technology. Temporal trends in means (and relative frequencies) were estimated at the gender–age level by best-fitting sample-weighted linear/polynomial regression models, with national trends estimated by a post-stratified population-weighting procedure. Temporal trends in distributional variability were estimated as the ratio of coefficients of variation.ResultsBetween 1998 and 2017 there was a steady, moderate improvement in mean 6MWD (absolute = 45 m (95% confidence interval (95%CI): 43–47); percent = 8.0% (95%CI: 7.6%–8.4%); effect size = 0.51 (95%CI: 0.48–0.54)). Gender- and age-related temporal differences in means were negligible. Variability in 6MWD declined substantially (ratio of coefficients of variation = 0.89, 95%CI: 0.87–0.92), with declines larger for women compared to men, and for 75–79-year-olds compared to 65–74-year-olds. Correspondingly, there were moderate and negligible increases in mean height and mass, respectively, and negligible increases in the percentage who participated in exercise/sport at least 3 days per week and at least 30 min per session.ConclusionThere has been a steady, moderate improvement in mean 6MWD for older Japanese adults since 1998, which is suggestive of corresponding improvements in both functional endurance and health. The substantial decline in variability indicates that the temporal improvement in mean 6MWD was not uniform across the distribution. Trends in 6MWD are probably influenced by corresponding trends in body size and/or participation in exercise/sport.  相似文献

Sport for Social Change and Development: Sustaining Transnational Partnerships and Adapting International Curriculums to Local Contexts in Rwanda     

Holly Collison  Simon Darnell  Richard Giulianotti  P. David Howe 《国际体育史杂志》2016,33(15):1685-1699

Abstract

Local Non-Governmental Organisations and sports organizations have been recognized as important and well positioned strategic implementing bodies by the ‘Sport for Development and Peace’ (SDP) sector. Whilst they may be experienced and knowledgeable of the historical and local sociocultural landscape, many seek to form transnational partnerships, for the purpose of expanding their capacity, sustainability, and expertise. Rwanda’s history of genocide frames much of its development objectives, and sport has been an integral method for implementing programmes that speak to social impact and reconciliation aims. This paper examines a transnational partnership active in Rwanda, that uses football as a tool to achieve its shared development goals. We conducted ethnographic fieldwork in Rwanda, by volunteering with the organizations as they delivered SDP programmes across the country. In doing so we were able to deconstruct the management and intricacies of this partnership and contextualize the important negotiations, management and style of approach when tackling difficult issues. This paper contributes to both expanding our knowledge of transnational partnerships and provides unique commentary that aligns the complexities of engaging with local populations in post-genocide Rwanda with ‘Sport for Social Development’ programming.  相似文献   

An Examination of a Small‐Group Decoding Intervention for Struggling Readers: Comparing Accuracy and Automaticity Criteria     

Roxanne F. Hudson  Carole Isakson  Taylor Richman  Holly B. Lane  Stephanie Arriaza‐Allen 《Learning disabilities research & practice》2011,26(1):15-27

In this study, we compared methods to improve the decoding and reading fluency of struggling readers. Second‐grade poor readers were randomly assigned to one of the two practice conditions within a repeated reading intervention. Both interventions were in small groups, were 20–28 min long, took place 2–4 days per week, and consisted of phonemic awareness training, letter sound practice, and practice in word families. Students in the accuracy condition (n= 27) practiced each page until they reached 98 percent accuracy while students in the accuracy + automaticity condition (n= 29) practiced until they reached rate (30–90 cwpm) and accuracy criteria. Hierarchical linear modeling revealed no differences between practice conditions in decoding accuracy, reading comprehension, and grade‐level text reading fluency. Significant differences favoring the accuracy + automaticity group were found in measures of decoding automaticity.  相似文献

“They don’t know what it’s like in here”: Incarcerated individuals’ communication with family members     

Pamela J. Lannutti  Holly M. Harner 《Qualitative Research Reports in Communication》2019,20(1):75-83

The incarcerated population is large and growing. Maintaining family connections during confinement is linked to positive outcomes, yet the family communication of incarcerated individuals is understudied. We examine the family communication of individuals incarcerated in an urban county jail for women. Four family communication themes were identified: 1) communication access and understanding, 2) family support, 3) parenting challenges, and 4) family conflict. The findings inform both theoretical and practical implications.  相似文献   

The brain and the US education system: Perpetuation of neuromyths     

Wilhelmina van Dijk  Holly B. Lane 《Exceptionality》2020,28(1):16-29

ABSTRACT

Misconceptions about the brain and its relation to education are widespread. This can lead to the implementation of ineffective methods and the waste of precious resources. To examine the extent of belief in neuromyths, a survey about the brain in education was conducted. Respondents (n = 169) came from special education (n = 83) and general education (n = 78), and included preservice teachers (n = 34), in-service teachers (n = 63), higher education faculty (n = 39), and educational leaders (n = 33). The survey contained 15 Myths and 18 Facts, and overall, participants were able to correctly identify approximately 66% of all the Facts. On the other hand, on average, respondents responded correctly for only one third of the Myths. The most commonly misidentified Myths were related to motor coordination exercises to improve literacy skills, the right brain-left brain myth, and learning styles. Higher education faculty were able to identify more Myths than any other group. Implications for teacher preparation and ongoing professional learning for teachers and educational leaders are discussed.  相似文献
