High levels of cardiovascular fitness and physical activity are associated with higher levels of cognitive function in people with HIV, thus, they may reduce the risk of developing HIV-associated neurocognitive disorder (HAND). This study aimed to investigate the effects of a 16-week aerobic exercise intervention on cognitive function in people with HIV. Eleven participants living with HIV were recruited into the study. Participants were randomised into either an exercise group (n = 5), that completed a 16-week aerobic exercise programme training, 3 times per week (2 supervised sessions and one unsupervised session) or a control group (n = 6) that received no intervention. Outcomes measured included cognitive function (Montreal cognitive assessment (MOCA) and the Trail making tests A and B), aerobic fitness (modified Bruce protocol), sleep quality (Pittsburgh sleep quality index; PSQI) and physical activity levels (seven-day accelerometry). At baseline, higher levels of moderate physical activity were positively correlated with higher MOCA scores and levels of aerobic fitness were negatively associated with Trail A scores (P = 0.04 and P = 0.001 respectively). However, exercise training did not induce any significant improvements in cognitive function or aerobic fitness. The overall mean adherence rate to the exercise programme was 60%. In conclusion, in the present study a 16-week aerobic exercise intervention did not affect the cognitive function of participants with HIV. It is likely that longer intervention periods and/or higher adherence rates to exercise might be needed for an aerobic exercise programme to be effective in improving cognitive function in a cohort with no baseline cognitive impairments.
Preadolescent children with CP spent less time in moderate and vigorous activity and more time in sedentary behavior than children with typical development. Children with CP also accumulated less continuous MVPA and vigorous activity as a result of achieving fewer sustained bouts of MVPA and vigorous activity throughout the day.
Introduction An evidence gap exists identifying the challenges and opportunities presented by digitally enhanced practical skill teaching and learning in health science education. A literature review was carried out to address this gap and to provide recommendations for overcoming identified challenges. Method A systematic search strategy was carried out using PRISMA guidelines. The research databases PubMed, ERIC, Medline and CINHL, were searched using MeSH terms. Barriers and opportunities were identified through deductive thematic analysis of the included articles. Results Of the 602 articles identified through the database screening, 29 were included in the current review. Potential challenges posed by technologically supported practical skill teaching identified were i) Inaccessibility and Inequity of Online Learning (ii) Digital illiteracy Among Staff (iii) Technological Challenges (iv) Lack of Engagement with Preparatory Material Hinders Practical Learning (v) Lack of Staff–Student Interaction (vi) Negative Attitudes Towards Online Learning and (vii) Skill Suitability. The opportunities presented by digital technologies identified were (i) Facilitates Higher Order Learning (ii) Ability to Practice in a Safe Environment (iii) Efficacious Use of Class Time (iv) Access to Education (v) Learning Brought to Life (vi) Diverse Range of Learning Materials (vii) Promotes Autonomous Learning. Discussion This literature review demonstrates the acceptability and usability of digitally enhanced practical teaching in health science education among students and educators. Conclusion To consolidate the positive disturbances in higher education from the Covid-19 pandemic, potential barriers to online delivery and student engagement must be acknowledged and addressed by relevant stakeholders. Recommendations detailed as part of this paper suggest means of overcoming barriers and leveraging opportunities.
The first proficiency panel showed that in general all participants performed well. Although, it also highlights areas for improvement for all participants in order to generate robust results for use in clinical diagnostics.
Objectives This study aimed to investigate the energy expenditure of common office-based tasks. The objectives were to: (a) test the classification of tasks as sedentary or light-intensity physical activity and (b) compare the energy expenditure of tasks under two postural conditions (sitting and standing). Background The sedentary nature of office work has been highlighted as a health risk, and strategies to reduce sedentary behavior at work have been developed. However, there is limited evidence to guide the utilization of sit-stand workstations in the workplace for metabolic health benefits. Method A repeated measures laboratory-based study compared the energy expenditure of common office tasks in sitting and standing using indirect calorimetry ( n = 22). Four standardized tasks (sitting/standing quietly, reading, typing, sorting paper) under two postural conditions (sitting, standing) were performed in a randomized order. Results The mean energy expenditure for all tasks in sitting and standing was <1.5 METs. There were no significant differences in the energy expenditure of doing the same task in sitting compared to standing. In a repeated measures ANOVA, task ( p < .001) had a greater influence on METs expended than posture ( p = .030). Conclusion The study confirmed that the difference in energy expenditure of tasks carried out in sitting compared to standing is negligible. Application The ubiquitous use and utility of sit-stand workstations in the workplace needs to be reviewed. Notwithstanding the potential benefits of movement that may occur naturally, this study confirmed that standing as opposed to sitting does not produce a clinically important increase in energy expenditure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
