Individual differences in the interleukin-6 response to maximal and submaximal exercise tasks

The inflammatory responsive cytokine interleukin-6 (IL-6) helps regulate immune responses to exercise. Evidence suggests that increases in IL-6 are related to exercise duration and intensity. However, the moderating effect of sex and underlying mediators have received limited attention. We compared plasma IL-6 responses to two cycling tasks with a resting control in young male (n = 12) and female (n = 12) recreationally active adults. Both 45 min tasks comprised an incremental test, either maximal or submaximal, followed by steady-state exercise at 55% peak power output. Interleukin-6 was elevated above baseline immediately after the maximal but not the submaximal task. Compared with the control condition, IL-6 was increased at 30 and 60 min after both exercise tasks. The IL-6 response was greater in women than men at 60 min after maximal exercise. Cortisol increased in both tasks compared with the control condition, the increase being greater after maximal than submaximal exercise. No associations were found between IL-6 responses and cortisol, heart rate, fitness or body mass index. The results show that 45 min of moderate-intensity exercise can increase IL-6 and suggest that the inclusion of maximal effort may accelerate this response. The finding that women showed a greater IL-6 response to maximal exercise may reflect a gender dimorphism in the immune response to stress.     

Digital Module 18: Automated Scoring https://ncme.elevate.commpartners.com

In this digital ITEMS module, Dr. Sue Lottridge, Amy Burkhardt, and Dr. Michelle Boyer provide an overview of automated scoring. Automated scoring is the use of computer algorithms to score unconstrained open-ended test items by mimicking human scoring. The use of automated scoring is increasing in educational assessment programs because it allows scores to be returned faster at lower cost. In the module, they discuss automated scoring from a number of perspectives. First, they discuss benefits and weaknesses of automated scoring, and what psychometricians should know about automated scoring. Next, they describe the overall process of automated scoring, moving from data collection to engine training to operational scoring. Then, they describe how automated scoring systems work, including the basic functions around score prediction as well as other flagging methods. Finally, they conclude with a discussion of the specific validity demands around automated scoring and how they align with the larger validity demands around test scores. Two data activities are provided. The first is an interactive activity that allows the user to train and evaluate a simple automated scoring engine. The second is a worked example that examines the impact of rater error on test scores. The digital module contains a link to an interactive web application as well as its R-Shiny code, diagnostic quiz questions, activities, curated resources, and a glossary.     

Activity-related typologies and longitudinal change in physical activity and sedentary time in children and adolescents: The UP&DOWN Study

The Impact of Three-Dimensional Printed Anatomical Models on First-Year Student Engagement in a Block Mode Delivery

Student engagement is known to have several positive effects on learning outcomes and can impact a student's university experience. High levels of engagement in content-heavy subjects can be difficult to attain. Due to a major institutional restructure, the anatomy prosection laboratory time per subject was dramatically reduced. In response, the authors set out to redesign their anatomy units with a focus on engaging the learning activities that would increase time-on-task both within and outside of the classroom. One of these curriculum changes was the implementation of a suite of anatomy learning activities centered on sets of three-dimensional printed upper limb skeleton models. A two-part mixed-method sequential exploratory design was used to evaluate these activities. Part one was a questionnaire that evaluated the students' engagement with and perceptions of the models. Part two involved focus groups interviews, which were an extension of the survey questions in part one. The results of the study indicated that the majority of students found the models to be an engaging resource that helped improve their study habits. As a result, students strongly felt that the use of the models inspired greater academic confidence and overall better performance in their assessments. Overall, the models were an effective way of increasing the engagement and deep learning, and reinforced previous findings from the medical education research. Future research should investigate the effects of these models on student's grades within osteopathy and other allied health courses.     

The art of the good life: culture and sustainable prosperity

ABSTRACT

The creative economy has seen cultural policy swallowed up by a narrow vision of economic growth, its impacts on the urban fabric captured by property developers, and its promises of meaningful activity challenged by the exploitation and inequities of cultural labour markets. So it needs to be abandoned and re-thought, but on what basis? This paper analyses the potential for cultural work to encourage alternative visions of the “good life”, in particular, how it might encourage a kind of “sustainable prosperity” wherein human flourishing is not linked to high levels of material consumption but rather the capabilities to engage with cultural and creative practices and communities. We critically explore these ideas in three locations: a London borough, a deindustrialised city in England’s midlands and a rural town on the Welsh/English border. Across these diverse landscapes and socio-economic contexts, we look at different versions of the good life and at the possibilities and constraints of cultural activity as a way of achieving kinds of sustainable prosperity.     

Task switching in overweight children: effects of acute exercise and age

The short-term after effects of a bout of moderate aerobic exercise were hypothesized to facilitate children's executive functioning as measured by a visual task-switching test. Sixty-nine children (mean age=9.2 years) who were overweight and inactive performed a category-decision task before and immediately following a 23-min bout of treadmill walking and, on another session, before and following a nonexercise period. The acute bout of physical activity did not influence the children's global switch cost scores or error rates. Age-related differences in global switch cost scores, but not error scores, were obtained. These results, in concert with several studies conducted with adults, fail to confirm that single bouts of moderately intense physical activity influence mental processes involved in task switching.     

Gendered performances and identity construction among UK female soccer players and netballers: a comparative study

This paper examines the gendered performances and identity construction of UK female University soccer players and netballers (n?=?31). Focus group interviews explored their sporting experiences with reference to body perceptions, and perceptions of their sporting bodies outside sporting contexts. Three themes resulted from data analysis, these being; (1) UK culture, body performances and femininity, (2) sporting culture, body performances and femininity and (3) transiency of body satisfaction across sport and non-sport contexts. Findings suggest that sport may not always provide an opportunity to challenge and resist dominant discourses. In both netball and soccer, a range of surveillance and management practices were used that served to perpetuate the value of a ‘feminine’ and assumed heterosexual body, and legitimize their sport participation through an emphasis on a hyper-femininity. The influence of sport subcultures on gendered performances and identity construction, along with implications for marketing sports participation to women are discussed.
