Moderate intensity cycling combined with cognitive dual-task improves selective attention

Physical and cognitive exercises have positive long-term effects on cognitive capacities. However, acute effects still are controversial. Here we determine the acute effects of physical exercise combined with concurrent cognitive exercise on cognitive performance in young adults. Simple reaction time, selective attention, and memory were evaluated in 23 young men before and after 30 min of stationary cycling exercise, 30 min of stationary cycling exercise combined with cognitive exercise, and 30 min of rest. Exercise intensity was continuously controlled to ensure exercise at moderate intensity. We found that physical exercise combined with cognitive dual-task improves selective attention. Both exercise conditions showed similar effects on simple reaction time, and memory was not affected by the different exercise conditions. We conclude that the combination of cycling exercise at moderate intensity with a cognitive exercise acutely improves selective attention in young adults. These results can be of particular interest for interventions aiming at improving selective attention in sports and for older adults and individuals with difficulty to suppress and filter out task-irrelevant information, like when receiving instruction or learning a new task or concept.

At-home Plant Growing Kits Foster Positive Student Experiences in an Online Horticulture Course

Hands-on activities are an essential part of horticulture education. However, facilitating hands-on activities in online horticulture courses is challenging partly due to a lack of literature that describes remote laboratories in the discipline. Here we describe our experience planning and executing a remote strawberry-growing activity in an online horticulture course at the University of Florida, Gainesville. Students received strawberry-growing kits that contained a strawberry (Fragaria ×ananassa) plant, substrate, and fertilizer. Instructions on growing the strawberry plant were delivered online and students had to provide weekly updates about the status of their plant for 5 weeks. At the end of the semester, students provided feedback about the hands-on activity in the form of an essay. Their answers were analyzed using text mining to gauge their perception of the activity. About 77% of students expressed positive sentiments about the remote activity including excitement, enjoyment, and knowledge gain. Students who expressed negative sentiments about the activity (≈23% of the total) focused on plant casualties and difficulties related to management practices. Overall, student essays and weekly updates reflected a relevant and engaging cognitive exercise in horticulture. Our results suggest that remote laboratories can improve the student experience in online courses and provide a footprint for successful implementation of similar activities in online horticulture courses.

On the Early Stage of Teaching Music to Less Gifted Children

The present work covers the topic of the early stage of teaching less musically gifted children. The work is rooted in the principles of inclusiveness in music education and is based on an extensive pedagogical experience of the author throughout a prolonged teaching career in a music school for children. The success in teaching less musically gifted children depends critically on the choice of pedagogical approaches by the teacher, on the teacher’s attitude toward a child, and on creativity and flexibility adopted by the teacher. Several practical rules—based on the author’s teaching experience and on pedagogical literature—are described as guidance to teachers working with less musically gifted children. The connection between music education and overall child development is also discussed. Music education is a stimulating cognitive exercise which plays an important role in overall cognitive development of a child. Musical education can stimulate not only intellectual development, improve general educational performance, but also yield improved physical condition. Musical education, therefore, is closely connected to the most valuable aspects of life.

Acquired Brain Injury Survivor Long-Term Cognitive Exercise Engagement Post–Speech Therapy Discharge

Purpose The purpose of this article is to promote the viewpoint that speech-language pathologists (SLPs) are well positioned to actively encourage individuals with cognitive-communication disorders following acquired brain injury (ABI) to engage in ongoing, long-term, cognitive exercise post–therapy discharge. Method This viewpoint article draws on evidence from the well-researched area of physical exercise, reports findings of early-stage research in the much less studied area of cognitive exercise, and highlights relevant aspects of motivational theory informing exercise participation. Informed by these, an evidence-supported model of cognitive exercise engagement is offered to inform ABI-targeted cognitive wellness empowerment efforts, and a case study illustrates clinical application of the model. Conclusions Exercise provides an opportunity to sustain or improve long-term health, function, and quality of life outcomes. It is within SLP scope of practice to collaborate with family members and other caregivers to empower individuals post-ABI, especially those with decreased self-management skills, to engage in long-term computerized and noncomputerized cognitive exercise following SLP therapy discharge. Ongoing research will further inform the evidence supporting the scholarly opinion presented in this viewpoint.

Effects of Cognitive/Exercise Dual-Task Program on the Cognitive Function, Health Status, Depression, and Life Satisfaction of the Elderly Living in the Community

The elderly population in Korea is rapidly increasing. It is necessary to develop multi-faceted and complex interventions for prevention and delay of dementia, balance improvement, and physical activity, among the elderly living in the community. This study aimed to examine the effects of the cognitive/exercise dual-task program on cognitive function, health status, depression, and life satisfaction of the elderly living in the community. A quasi-experimental study design using a pretest-posttest control group was employed. The study included a total of 65 elderly participants (intervention: n = 32, control: n = 33) in Seoul, South Korea. The cognitive/exercise dual-task program as an intervention was composed of 20 sessions for a total of 10 weeks, held twice a week for about 50 min each session. Measures were general characteristics of study participants, the Korean version of Mini-Mental State Examination (MMSE-K), Korean elderly health status assessment tool, Korean version of Geriatric Depression Scale, and the elderly life satisfaction scale. Data were collected from October 2020 to March 2021. There were statistically significant differences on cognitive function, health status, depression, and life satisfaction between two groups. The cognitive/exercise dual-task program was an effective intervention for improving cognitive function, health status, and life satisfaction, and for decreasing depression of the elderly living in the community. Health care providers need to pay attention to cognitive/exercise dual-task programs for elderly living in the community.

Multicomponent Training Prevents Memory Deficit Related to Amyloid-β Protein-Induced Neurotoxicity

Background: Alzheimer’s disease (AD) is characterized by the accumulation of the amyloid-β peptide in the brain, leading to early oxidative stress and neurotoxicity. It has been suggested that physical exercise could be beneficial in preventing AD, but studies with multicomponent training are scanty. Objective: Verify the effects of multicomponent exercise training to prevent deficits in recognition memory related to Aβ neurotoxicity. Methods: We subjected Wistar rats to multicomponent training (including aerobic and anaerobic physical exercise and cognitive exercise) and then infused amyloid-β peptide into their hippocampus. Results: We show that long-term multicomponent training prevents the amyloid-β-associated neurotoxicity in the hippocampus. It reduces hippocampal lipid peroxidation, restores antioxidant capacity, and increases glutathione levels, finally preventing recognition memory deficits. Conclusion: Multicomponent training avoids memory deficits related to amyloid-β neurotoxicity on an animal model.

Can Exergames Be Improved to Better Enhance Behavioral Adaptability in Older Adults? An Ecological Dynamics Perspective

Finding effective training solutions to attenuate the alterations of behavior and cognition in the growing number of older adults is an important challenge for Science and Society. By offering 3D computer-simulated environments to combine perceptual-motor and cognitive exercise, exergames are promising in this respect. However, a careful analysis of meta-analytic reviews suggests that they failed to be more effective than conventional motor-cognitive training. We analyzed the reasons for this situation, and we proposed new directions to design new, conceptually grounded, exergames. Consistent with the evolutionary neuroscience approach, we contend that new solutions should better combine high level of metabolic activity with (neuro)muscular, physical, perceptual-motor, and cognitive stimulations. According to the Ecological Dynamics rationale, we assume that new exergames should act at the agent–environment scale to allow individuals to explore, discover, and adapt to immersive and informationally rich environments that should include cognitively challenging tasks, while being representative of daily living situations.

APATHY IN FRONTOTEMPORAL DEMENTIA AND PROGRESSIVE SUPRANUCLEAR PALSY: AN EXPLORATORY NEUROIMAGING INVESTIGATION

Background: Apathy is a multidimensional syndrome that impairs motivation and mechanisms of behavioural regulation. As apathy is almost ubiquitous in neurodegenerative disorders, understanding the neural basis is required to expand knowledge and ameliorate our instruments. Objective: Verify the feasibility, safety, and adherence of a remote physical and cognitive exercise protocol for elders; and to compare two different protocols and its effects on strength, cognitive functions and well-being. Methods: Use of the PICO strategy, conducted on September 17, on PubMed using “Alzheimer disease” and “diabetes mellitus” as descriptors, identifying 14 articles, selecting 4 after screening. Inclusion criteria: clinical and randomized controlled trials with diabetic and Alzheimer patients, published on the last 5 years. Exclusion criteria: articles focused on medications. Results: Overall adherence to the proposed sessions was 82,36% (sd16,8) in IG and 76,5% (sd24,04) in CG. There were no serious adverse events or drop-outs during the study. There was an improvement in strength and verbal fluency for IG and GDS for both groups (p ≤ 0,05). Conclusion: Both protocols seem a feasible program, reaching an acceptable level of adherence and safety. The technology used can represent a sustainable path for large scale use to promote aging active in developing countries.

The Use of Home-Based Nonimmersive Virtual Reality to Encourage Physical and Cognitive Exercise in People With Mild Cognitive Impairment: A Feasibility Study

Individuals with mild cognitive impairment are at risk of cognitive and physical decline. Virtual reality (VR) exercise may provide beneficial physical and cognitive exercise. The objectives of this study were to assess the feasibility and safety of home-based VR exercise and to provide pilot data for physical and cognitive efficacy. Eleven individuals with mild cognitive impairment (seven males/four females, average 78 years old, and average 3 years since diagnosis) performed a 30-min home-based VR exercise program 5 days a week for 6 weeks. The VR platform was successfully installed in participants’ homes, and all participants were able to learn the VR program and progress. Participants completed 99% of the prescribed exercise. There were no major adverse events. Most participants enjoyed the VR program and reported physical benefits; fewer reported cognitive benefits. No physical or cognitive outcome measures showed change after 6 weeks. Home-based VR exercise is safe and feasible in individuals with mild cognitive impairment.
