Thirty-one young (mean age = 20.8 years) and 30 older (mean age = 71.5 years) men and women categorized as physically active (n = 30) or inactive (n = 31) performed an executive processing task while standing, treadmill walking at a preferred pace, and treadmill walking at a faster pace. Dual-task interference was predicted to negatively impact older adults’ cognitive flexibility as measured by an auditory switch task more than younger adults; further, participants’ level of physical activity was predicted to mitigate the relation. For older adults, treadmill walking was accompanied by significantly more rapid response times and reductions in local- and mixed-switch costs. A speed-accuracy tradeoff was observed in which response errors increased linearly as walking speed increased, suggesting that locomotion under dual-task conditions degrades the quality of older adults’ cognitive flexibility. Participants’ level of physical activity did not influence cognitive test performance.

The purpose of this study was to assess participants’ ability to perform tasks requiring attention, short term memory, and simple motor skill while sitting, standing or walking at an active workstation.
Fifty participants completed the Stroop Color Word test (SCWT), Auditory Consonant Trigram test (ACTT), and Digital Finger Tapping test (DFTT) while sitting, standing and walking 1.6 km/h at an active workstation.
A significant difference was found for DFTT, but no differences across conditions were found on ACTT or SCWT. Examination of the linear contrasts and post hoc means comparison tests revealed significant differences in DFTT scores between sitting and walking (t = 2.39 (49) P < .02) and standing and walking (t = 2.28 (49) P < .03). These results indicate that adding the walking task to the ACTT and SCWT conditions results in no decrement in performance on these tasks. Conversely, adding the walking task to the DFTT condition results in reduced performance on the DFTT task.
These results further support the potential of active workstations to increase physical activity in the workplace without compromising cognitive capabilities.

The built and social environments may contribute to physical activity motivations and behavior. We examined the extent to which the Theory of Planned Behavior (TPB) mediated the association between neighborhood walkability and walking.
Two random cross-sectional samples (n = 4422 adults) completed telephone interviews capturing walking-related TPB variables (perceived behavioral control (PBC), attitudes, subjective norm, intention). Of those, 2006 completed a self-administered questionnaire capturing walkability, social support (friends, family, dog ownership), and neighborhood-based transportation (NTW) and recreational walking (NRW). The likelihood of undertaking 1) any vs. none and 2) sufficient vs. insufficient levels (≥150 vs. <150 minutes/week) of NTW and NWR, in relation to walkability, social support, and TPB was estimated.
Any and sufficient NTW were associated with access to services, connectivity, residential density, not owning a dog (any NTW only), and friend and family support. Any and sufficient NRW were associated with neighborhood aesthetics (any NRW only), dog ownership, and friend and family support. PBC partially mediated the association between access to services and NTW (any and sufficient), while experiential attitudes partially mediated the association between neighborhood aesthetics and any NRW.
Interventions that increase positive perceptions of the built environment may motivate adults to undertake more walking.

Many fouls committed in football (called soccer in some countries) are ambiguous, and there is no objective way of determining who is the “true” perpetrator or the “true” victim. Consequently, fans as well as referees often rely on a variety of decision cues when judging such foul situations. Based on embodiment research, which links perceptions of height to concepts of strength, power, and aggression, we argue that height is going to be one of the decision cues used. As a result, people are more likely to attribute a foul in an ambiguous tackle situation to the taller of two players. We find consistent support for our hypothesis, not only in field data spanning the last seven UEFA Champions League and German Bundesliga seasons, as well as the last three FIFA World Cups, but also in two experimental studies. The resulting dilemma for refereeing in practice is discussed.

Physical activity is predictive of better cognitive performance and lower risk of Alzheimer’s disease (AD). The apolipoprotein E gene (APOE) is a susceptibility gene for AD with the e4 allele being associated with a greater risk of AD. Cross-sectional and prospective research shows that physical activity is predictive of better cognitive performance for those at greater genetic risk for AD. However, the moderating role of APOE on the effects of a physical activity intervention on cognitive performance has not been examined. The purpose of this manuscript is to justify the need for such research and to describe the design, methods, and recruitment tactics used in the conductance of a study designed to provide insight as to the extent to which cognitive benefits resulting from an 8-month physical activity program are differentiated by APOE e4 status. The effectiveness of the recruitment strategies and the feasibility of recruiting APOE e4 carriers are discussed.

This study identified perceived physical activity (PA) enablers and barriers among a racially/ethnically and geographically diverse group of older adults. Data were from 42 focus groups conducted with African Americans, American Indians, Latinos, Chinese, Vietnamese, and non-Hispanic Whites (hereafter Whites). Constant-comparison methods were used to analyze the data. Common barriers were health problems, fear of falling, and inconvenience. Common enablers were positive outcome expectations, social support, and PA program access. American Indians mentioned the built environment and lack of knowledge about PA as barriers and health benefits as an enabler more than participants in other groups. Whites and American Indians emphasized the importance of PA programs specifically designed for older adults. Findings suggest several ways to promote PA among older people, including developing exercise programs designed for older adults and health messages promoting existing places and programs older adults can use to engage in PA.

In developing a senior lecture for the 2014 national meeting of the North American Society for the Psychology of Sport and Physical Activity, I had the opportunity to reflect upon a career of research and to focus on three interesting questions that my colleagues and I have attempted to address. These questions have led to several studies that all revolve around identifying ways to increase the effects of exercise on cognitive performance. In particular, the questions examine the possibility of increasing effects by focusing on particular populations (e.g., older adults, children) and by increasing our understanding of dose-response relationships between exercise parameters (e.g., intensity, duration) and cognitive outcomes. I present empirical evidence relative to each of these questions and provide directions for future research on physical activity and cognitive functioning.

The NCAA Growth, Opportunities, Aspirations and Learning of Students in College data were used to explore the relationship between self-reported high levels of difficulties thinking or concentrating and grade point average (GPA) in college student-athletes. We specifically investigated the mediators of the relationship between self-reported high levels of difficulties thinking or concentrating and GPA. Results revealed there was a significant indirect effect between self-reporting the highest level of difficulties thinking or concentrating and service use through GPA, moderated by identity, full model: F(4, 14738) = 184.28, p < .001; R 2 = .22. The athletic/academic identity variable acted as a moderator of the mediating effect of GPA on the relationship between self-reported high levels of difficulties thinking or concentrating and the use of academic resources on campus. If a student-athlete who is self-reporting high levels of difficulties thinking or concentrating identifies more as a student, GPA is likely to prompt academic service use. However, if the student-athlete identifies more as an athlete, GPA is less likely to lead to use of campus academic support resources.

Our increasingly inactive lifestyle is detrimental to physical and cognitive health. This review focuses on the beneficial relation of physical activity and aerobic fitness to the brain and cognitive health in a youth and elderly population to highlight the need to change this pattern. In children, increased physical activity and higher levels of aerobic fitness have been associated with superior academic achievement and cognitive processes. Differences in brain volumes and brain function of higher-fit and lower-fit peers are potential mechanisms underlying the performance differences in cognitive challenges. We hope that this research will encourage modifications in educational policies that will increase physical activity during the school day. In addition, older adults who participate in physical activity show higher performance on a variety of cognitive tasks, coupled with less risk of cognitive impairment. The cognitive enhancements are in part driven by less age-related brain tissue loss and increases in the efficiency of brain function. Given the increasing aging population and threat of dementia, research about the plasticity of the elderly active brain has important public health implications. Collectively, the data support that participation in physical activity could enhance daily functioning, learning, achievement, and brain health in children and the elderly.
