Trial Summary
What is the purpose of this trial?This study aims to expand on previous findings and compare the effects of an active break (ten minutes of walking or upper body movement), a digital break (ten minutes of phone use), and no break on memory and attention in medical students after a prolonged period of studying. The List Learning Task, Stroop Test, and Sustained Attention to Response Task will be administered to measure memory, executive function, and attention, respectively. Information on how different types of breaks affect memory and attention may prompt medical students to be more mindful and intentional of the way they spend their time in between studying.
How does the treatment in the Study Breaks for Executive Function trial differ from other treatments for executive function?
The treatment in the Study Breaks for Executive Function trial is unique because it likely involves physical activity, which has been shown to improve executive function, especially in sedentary individuals. Unlike other treatments that may focus on medication or cognitive exercises, this approach emphasizes regular physical activity sessions, which have been found to enhance specific aspects of executive function like inhibitory control and working memory.
134510Is taking study breaks involving physical activity or digital activities safe for humans?
Research on physical activity interventions, which can include study breaks, generally shows they are safe for humans. These activities are often linked to improved cognitive functions like memory and executive function, especially in sedentary individuals and older adults, without reported safety concerns.
123810What data supports the effectiveness of the treatment Physical Activity Study Break for improving executive function?
Research shows that physical activity can have a small to moderate positive effect on executive function, especially in sedentary individuals, by improving skills like inhibitory control and working memory.
678910Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications.

The effect of physical activity on executive function: a brief commentary on definitions, measurement issues, and the current state of the literature. [2022]The purpose of the present commentary is to introduce relevant issues with respect to the measurement of executive function in physical activity studies. Suggested definitions of executive function are introduced, and executive function tasks that are commonly used in the neuropsychological literature are presented and briefly described. The extant literature on physical activity and cognition is discussed, and issues relative to the limitations of this body of literature are raised. In summary, research on the effect of physical activity on executive function is still in its infancy. We encourage researchers in this field to provide a clear definition of executive function, to carefully consider the relevance of published effect sizes to their own research questions, and to consider either providing a logical rationale for their selection of particular executive function measures or to use multiple measures of executive function when exploring relationships between physical activity and executive function.
Impact of physical activity on executive functions in aging: a selective effect on inhibition among old adults. [2022]The purposes of this study were to determine the impact of physical activity on three different executive functions (shifting, inhibition, and updating) and to examine whether cardiovascular fitness was a good mediator of the positive link(s) between these variables. Sixty-three young adults (18-28 years), 30 young-old adults (60-70 years) and 30 old adults (71-81 years) were divided into physically active and sedentary groups according to physical activity level (assessed from an accelerometer and the Historical Leisure Activity Questionnaire). Cardiovascular fitness was assessed by VO2max from the Rockport 1 mile. Each executive function was assessed through three different experimental tasks. ANCOVAs revealed that the effect of physical activity level was specific to the old adults and significant for inhibition, but not for updating and shifting. Mediation analysis showed that this positive effect in the old adults group was mediated by cardiovascular fitness level. The present findings highlight the positive linkages among physical activity, cardiovascular fitness, and inhibition in aging.
Executive function influences sedentary behavior: A longitudinal study. [2020]Background: No study has evaluated the effects of executive function on follow-up sedentary behavior, which was this study's purpose. Methods: A longitudinal design was employed among 18 young adult college students (Mage = 23.7 years; 88.9% female). Accelerometer-determined sedentary behavior and physical activity, along with executive function, were assessed at baseline. Approximately 8 weeks later, re-assessment of accelerometer-determined sedentary behavior and physical activity occurred. Executive function was assessed using the Parametric Go/No-Go (PGNG) computer task. From this, 2 primary executive function outcome parameters were evaluated, including the Simple Rule and Repeating Rule. Results: After adjusting for baseline sedentary behavior, age, gender, body mass index and baseline moderate-to-vigorous physical activity (MVPA), for every 25% increase in the number of correctly identified targets for the Repeating rule at the baseline assessment, participants engaged in 91.8 fewer minutes of sedentary behavior at the follow-up assessment (β = -91.8; 95% CI: -173.5, -10.0; P = 0.03). Results were unchanged when also adjusting for total baseline or follow-up physical activity. Conclusion: Greater executive function is associated with less follow-up sedentary behavior.
Effects of acute exercise in the sitting position on executive function evaluated by the Stroop task in healthy older adults. [2020][Purpose] Exercise effects on executive functioning depend on exercise mode. We tested the effects of three acute exercises in the sitting position-stepping, stretching, and finger movement-on older adults' executive functioning in comparison to a resting state (i.e., control condition). [Subjects and Methods] Participants were 26 healthy older adults (mean age, 71.8 ± 4.7 years). All participants performed the three sitting exercises for 10 minutes; resting for an equal amount of time was used as a control condition. These four conditions were presented in random order. The color-word matching Stroop task was used to evaluate executive function before and after the sitting exercises and control condition. [Results] All three sitting exercises significantly reduced Stroop interference scores, while the control condition did not. There was a significant difference between the finger movement exercise and the control condition in pre-to-post-intervention changes in Stroop interference scores. [Conclusion] The acute finger movement exercise was especially beneficial for executive function as evaluated by the color-word matching Stroop task.
The association between sedentary behavior and cognitive ability in older adults. [2020]Executive functions (EF) are a grouping of cognitive abilities essential for daily life. Previous research has shown that physical activity (PA) may in fact preserve EF in older adults, but the link between sedentary behavior (SB) and cognitive ability has been less explored. The purpose of this study was to examine the relationship between SB and cognition (executive function and memory) in older adults. Seventy five older adults (74.6 ± 9 years) self-reported their sedentary time (ST) and PA, as well as EF ability (paper-based measure of EF). Participants also completed several performance-based measures of EF and a memory task. Older adults who were less sedentary had superior EF and memory (e.g., Stroop time was significantly faster in less sedentary adults (34.7 s ± 1.9) compared to more sedentary adults (39.6 s ± 1.8), p = .02). Regression analysis showed that total ST was associated with several measures of EF after adjusting for age, and physical activity (e.g., Stroop time β =  .005 (.002, .009). Less cognitively demanding SB (TV viewing and napping) was associated with worse performance on most EF and in the memory task. Performing a hobby was also associated with lower levels of EF and memory. For example, the building times for the Lego task were positively related to napping (r2 = .34), watching TV (r2 = .27), and performing a hobby (r2 = .46). Associations of ST with cognitive abilities were more pronounced in older adults who engaged in less PA. These results suggest that SB may play an important role in cognitive abilities of older adults. Longitudinal studies using performance-based assessments of EF are needed.

A Randomized Controlled Trial of High-Intensity Exercise and Executive Functioning in Cognitively Normal Older Adults. [2021]There is a paucity of interventional research that systematically assesses the role of exercise intensity and cardiorespiratory fitness, and their relationship with executive function in older adults. To address this limitation, we have examined the effect of a systematically manipulated exercise intervention on executive function.
Effects of physical exercise on executive function in cognitively healthy older adults: A systematic review and meta-analysis of randomized controlled trials: Physical exercise for executive function.

Aerobic physical activity to improve memory and executive function in sedentary adults without cognitive impairment: A systematic review and meta-analysis. [2021]The worldwide population of adults ages 50 and older continues to increase and is projected to reach over 2.3 billion by 2030. Aging is the biggest risk factor for cognitive impairment and dementia. Aerobic physical activity may improve cognitive functioning, thus delaying aging-related cognitive decline. The purpose of this review was to examine the effect of aerobic physical activity on memory and executive function in sedentary adults with no known cognitive impairment. PubMed, CINAHL, Psycinfo, and Cochrane Library databases were systematically searched for peer-reviewed articles up to July 2019. Randomized controlled trials of sedentary adults, aged 50 and older, that compared an aerobic physical activity intervention to either no treatment or alternative active comparator and reported outcome measures of memory and/or executive function were included. A random effects meta-analysis was performed to examine the separate effect sizes for memory and executive function. Nine studies met inclusion criteria and contributed either memory and/or executive function effect sizes (n = 547). Results from the random effects meta-analysis suggested, by post-intervention, a large effect size for the aerobic physical activity interventions on memory (g = 0.80, 95%CI: 0.14-1.47; n = 7; p = 0.02) and a small effect on executive function (g = 0.37, 95%CI: 0.04-0.69; n = 6; p = 0.03). Aerobic physical activity may improve memory and executive function in sedentary adults without cognitive impairment. Policymakers and providers should promote aerobic physical activity in this population, and further research should investigate the most effective ways to promote aerobic physical activity in mid-life to older adults.
Active Gains in brain Using Exercise During Aging (AGUEDA): protocol for a randomized controlled trial. [2023]Alzheimer's disease is currently the leading cause of dementia and one of the most expensive, lethal and severe diseases worldwide. Age-related decline in executive function is widespread and plays a key role in subsequent dementia risk. Physical exercise has been proposed as one of the leading non-pharmaceutical approaches to improve executive function and ameliorate cognitive decline. This single-site, two-arm, single-blinded, randomized controlled trial (RCT) will include 90 cognitively normal older adults, aged 65-80 years old. Participants will be randomized to a 24-week resistance exercise program (3 sessions/week, 60 min/session, n = 45), or a wait-list control group (n = 45) which will be asked to maintain their usual lifestyle. All study outcomes will be assessed at baseline and at 24-weeks after the exercise program, with a subset of selected outcomes assessed at 12-weeks. The primary outcome will be indicated by the change in an executive function composite score assessed with a comprehensive neuropsychological battery and the National Institutes of Health Toolbox Cognition Battery. Secondary outcomes will include changes in brain structure and function and amyloid deposition, other cognitive outcomes, and changes in molecular biomarkers assessed in blood, saliva, and fecal samples, physical function, muscular strength, body composition, mental health, and psychosocial parameters. We expect that the resistance exercise program will have positive effects on executive function and related brain structure and function, and will help to understand the molecular, structural, functional, and psychosocial mechanisms involved.
Physical activity on executive function in sedentary individuals: Systematic review and meta-analysis of randomized controlled trials. [2023]Physical activity has been demonstrated to promote cognitive performance. However, the relationship between physical activity and executive function (EF) in sedentary individuals is not fully understood. This meta-analysis examined the impact of physical activity on EF in sedentary individuals and evaluated potential moderators of the relationship between physical activity and EF. In accordance with the PRISMA guidelines, the electronic databases MEDLINE, Embase, PsycINFO and Web of Science were searched. Included studies had to report sedentary individuals randomized to either a physical activity group or a control group. Subgroup analyses of EF sub-domains, exercise prescription and age were conducted alongside the overall meta-analysis. Thirteen RCT studies were included, with a total of 752 participants. Results showed a small to moderate beneficial effect of physical activity on EF (SMD = 0.24, 95% CI 0.08 to 0.40). In subgroup analysis by EF sub-domains, physical activity enhanced inhibitory control (SMD = 0.38, 95% CI 0.12 to 0.63) and working memory (SMD = 0.22, 95% CI -0.05 to 0.49), but not cognitive flexibility (SMD = 0.11, 95% CI -0.18 to 0.41). Interventions with an intervention length > 12 weeks improved overall EF (SMD = 0.26, 95% CI 0.06 to 0.46), but intervention length ≤ 12 weeks did not (SMD = 0.20, 95% CI -0.08 to 0.47). Interventions with session time ≥ 45 minutes improved overall EF (SMD = 0.47, 95% CI 0.22 to 0.77), but session time
