Over Time

There is evidence that an acute bout of exercise confers cognitive benefits, but it is largely unknown what the optimal mode and duration of exercise is and how cognitive performance changes over time after exercise. We compared the cognitive performance of 31 older adults using the Stroop test before, immediately after, and at 30 and 60 min after a 10 and 30 min aerobic or resistance exercise session. Heart rate and feelings of arousal were also measured before, during, and after exercise. We found that, independent of mode or duration of exercise, the participants improved in the Stroop Inhibition task immediately postexercise. We did not find that exercise influenced the performance of the Stroop Color or Stroop Word Interference tasks. Our findings suggest that an acute bout of exercise can improve cognitive performance and, in particular, the more complex executive functioning of older adults.

<b><i>Introduction:</i></b> Parkinson’s disease (PD) progressively impairs motor and cognitive performance. The current tools to detect decline in motor and cognitive functioning are often impractical for busy clinics and home settings. To address the gap, we designed an instrumented trail-making task (iTMT) based on a wearable sensor (worn on the shin) with interactive game-based software installed on a tablet. The iTMT test includes reaching to 5 indexed circles, a combination of numbers (1–3) and letters (A&amp;B) randomly positioned inside target circles, in a sequential order, which virtually appears on a screen kept in front of the participants, by rotating one’s ankle joint while standing and holding a chair for safety. By measuring time to complete iTMT task (iTMT time), iTMT enables quantifying cognitive-motor performance. <b><i>Purpose:</i></b> This study’s objective is to examine the feasibility of iTMT to detect early cognitive-motor decline in PDs. <b><i>Method:</i></b> Three groups of volunteers, including 14 cognitively normal (CN) older adults, 14 PDs, and 11 mild cognitive impaireds (MCI), were recruited. Participants completed MoCA, 20 m walking test, and 3 trials of iTMT. <b><i>Results:</i></b> All participants enabled to complete iTMT with &#x3c;3 min, indicating high feasibility. The average iTMT time for CN-Older, PD, and MCI participants were 20.9 ± 0.9 s, 32.3 ± 2.4 s, and 40.9 ± 4.5 s, respectively. After adjusting for age and education level, pairwise comparison suggested large effect sizes for iTMT between CN-older versus PD (Cohen’s <i>d</i> = 1.7, <i>p</i> = 0.024) and CN-older versus MCI (<i>d</i> = 1.57, <i>p</i> &#x3c; 0.01). Significant correlations were observed when comparing iTMT time with the gait speed (<i>r</i> = −0.4, <i>p</i> = 0.011) and MoCA score (<i>r</i> = −0.56, <i>p</i> &#x3c; 0.01). <b><i>Conclusion:</i></b> This study demonstrated the feasibility and early results supporting the potential application of iTMT to determine cognitive-motor and distinguishing individuals with MCI and PD from CN-older adults. Future studies are warranted to test the ability of iTMT to track its subtle changes over time.

Delayed Effects

Research on the acute effects of exercise on cognitive performance by older adults is limited by a focus on nonhealthy populations. Furthermore, the duration of cognitive improvements after exercise has not been examined. Thus, this study was designed to test the immediate and delayed effects of acute exercise on cognitive performance of healthy older adults. Cognitive performance was assessed using the Stroop task. Participants were randomly assigned to an exercise (20 min of walking) or control (sitting quietly) condition. The Stroop task was administered at baseline and at 12 time points after treatment. Acute exercise resulted in better Stroop test performance immediately postexercise; however, the effects were limited to the color test. No effects of exercise on performance were observed for the Stroop interference or inhibition tests. Findings suggest that acute exercise performed by healthy older adults has short-term benefits for speed of processing but does not affect other types of cognitive functioning.

Abstract Background and Objectives Meditation and mind–body exercises are suggested to delay decline or enhance cognitive capabilities in older adults. However, their effectiveness remains uncertain. This study assessed the effectiveness of meditation and mind–body exercises to improve cognition in elderly people aged 60 years or above. Moderator variables were also explored. Research Design and Methods A databases search (MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane Library, Web of Science, CNKI, and Wangfang) was conducted from the first available date to January 10, 2018. Inclusion criteria include (a) human older adults aged 60 years or above, (b) meditation, Tai Chi, Qigong, or yoga intervention, (c) intervention should be structured, (d) inclusion of a control group, (e) at least one outcome measure of cognition was measured at baseline and post-training, and (f) peer-reviewed journal articles in English or Chinese. Results Forty-one studies (N = 3,551) were included in the meta-analysis. In general, meditation and mind–body exercises improve cognition in the elderly people (SMD = 0.34, 95% CI: 0.19 to 0.48), but the cognition-enhancing effects depend on the type of exercise. In addition, cognitive performance is only improved when the length of intervention is longer than 12 weeks, exercise frequency is 3–7 times/week, or duration of an exercise session is 45–60 min/session. Discussion and Implications This study suggests that meditation and mind–body exercises are effective to improve cognition of older adults aged 60 years or above, and exercise parameters should be considered for intervention planning.

Aging is increasing worldwide; hence, aging-related health is also more relevant. Well-programmed physical exercise is now an indispensable tool to achieve active aging and preserve older people’s health. Such “well-programmed” exercise requires efficient and useful tools to measure the activity. The objective of this study is to evaluate the effectiveness of accelerometers to estimate two different intensities of physical exercise in older people. Thirty-eight subjects (64.5 ± 5.3 years) were measured during two different sessions of physical exercise: one moderate in intensity, the other of low intensity. Heart rate and accelerometry were recorded and analyzed. The results showed that the two variables in the physical exercise sessions were not highly correlated, and that accelerometry did not seem useful to assess low-intensity sessions not based on walking.

Background Regular exercise training stimulates physiological adaptations to improve physical performance, reduce chronic disease risk, and slow age-related cognitive decline. Since the physiological mechanisms responsible for aging-associated cognitive decline are not yet fully understood, and training-induced physiological adaptations responsible for performance measure improvements are specific to the type (aerobic vs. strength) and intensity of training, studies are needed to assess the relationships between physical performance measures and cognitive performance in older adults. These results could be used to guide exercise prescriptions with the goal of improving age-related cognitive performance. The purpose of this study was to investigate the relationship between physical performance measures and cognitive performance in a population of community dwelling, ethnically diverse older adults. Methods The cognitive performance of ninety independent, community dwelling participants (69 female, 21 male), aged 75 ± 9.5 years (mean ± SD) was measured with the Modified Mini-Mental State Test (3MS), Trailmaking Tests A and B (TMT A & B), and the Animal Naming test. Sociodemographic (age, sex, ethnicity, medication use, years of education) and anthropometric data were collected, physical activity was assessed with the Physical Activity Scale for the Elderly (PASE), peak hand-grip strength, distance walked in the 6MWT, and heart rate pre-, during, and up to 5 min. post- 6MWT were measured. Forward stepwise multiple regression analyses were performed with each cognitive measure as a dependent variable. Results and Discussion Controlling for sociodemographic covariates, peak heart rate during the 6MWT (6MWT HRPEAK) was positively correlated with performance in the 3MS (p < 0.017), and TMT A (p < 0.001) and B (p < 0.029). Controlling for sociodemographic covariates, PASE was positively (p = 0.001), and β-blocker use negatively (p = 0.035), correlated with performance on the Animal Naming test. Also, controlling for sociodemographic covariates, PASE was positively correlated with performance on the TMT A (p = 0.017). Here we show that higher peak heart rate during the 6MWT is positively correlated with cognitive performance in a population of community dwelling, ethnically diverse older adults (ages 60–95 years). Conclusion Higher peak heart rate during the 6MWT was found to be independently and positively correlated with cognitive function in community-dwelling older adults. Although additional work is needed, these results are promising and suggest that physicians, exercise professionals, and/or fitness/fall prevention programs may use peak heart rate during the 6MWT to easily monitor exercise intensity to support cognitive health.

Smoking can weaken immune function as reported in previous studies. However, benefits of exercise in reducing negative effects of smoking on salivary lactoferrin responses is scarce to date. Hence, the purpose of this study is to determine the effects of an acute bout of exercise on salivary lactoferrin responses among smokers and non-smokers. Eighteen sedentary men were recruited; nine smokers (age = 22.4 ± 1.4 years; BMI = 22.1 ± 1.1 kg/m2) and nine non-smokers (age = 22.1 ± 0.7 years old; BMI = 22.5 ± 1.9 kg/m2). In this study, participants cycled at an intensity of 60% maximum heart rate for 60 minutes. Participants were given cool water as much as 3 ml/kg body weight at minutes 20 and 40 during the exercise session. Participants’ body weight and saliva samples were collected at pre and post-exercise. Heart rate and rate of perceived exertion (RPE) were recorded at pre, during and post-exercise. Mixed ANOVA was used to measure significant differences between groups and within group. The results showed that saliva flow rate, lactoferrin concentration and lactoferrin secretion rate were not significantly different (p>0.05) between smokers and non-smokers groups and also between pre and post-exercise within each group. Heart rate and RPE showed significant increased (p<0.05) during the exercise session in both groups. As a conclusion, acute bout of exercised does not affect salivary lactoferrin responses among sedentary smokers and non-smokers men.

Abstract Despite being a risk factor for cardiovascular disease, suicidal ideation, and mortality among U.S. older adults, research on hopelessness and how it changes over time are lacking. Although hopelessness generally increases with age, levels of hopelessness may be influenced by race/ethnicity and social or economic factors. This study uses longitudinal data from 8,359 individuals from the Health and Retirement Study to examine race differences in trajectories of hopelessness from 2006 to 2018. We used linear mixed models to estimate trajectories of hopelessness for blacks, whites and Hispanics age 51 and older. The model was fit with a natural spline cubic function to model changes in time trends of hopelessness and the interaction between time and race. Models controlled for demographic characteristics, socioeconomic status, health status, and psychosocial factors that influence hopelessness. We found that older Hispanics have the highest levels of hopelessness, followed by non-Hispanic blacks and non-Hispanic whites. Trajectories of hopelessness were non-linear and differed by race. For older whites, hopelessness increased from 2006-2010 and then decreased until 2018. For older blacks, it decreased the entire time period but did so at a decreasing rate; and, for older Hispanics, hopelessness decreased from 2006-2012 and then increased thereafter. Our study shows that hopelessness generally decreased over time among older adults between 2006 and 2018 in race-specific ways, despite generally increasing with age. These findings suggest that race, age and period effects differentially influence trajectories of hopelessness. Factors contributing to these differences may be related to concurrent social and economic conditions.

RÉSUMÉNous avons théorisé que les changements au fil du temps dans les performances cognitives sont associés à des changements dans les perceptions, les attitudes et les comportements d’auto-régulation des personnes âgées qui conduisent. Les adultes âgés en bonne santé (n = 928) ont subi les évaluations cognitives au début avec deux suivis annuels subséquents, et ils ont rempli des formulaires avec des échelles qui mesurent leurs perceptions, les attitudes et les comportements de conduite. L’analyse multivariée montre des petites relations, mais statistiquement significatives, entre les tests cognitifs et les mesures qui ont été auto-déclarée, les plus grandes amplitudes entre les scores étant sur les sentiers B tâche cognitive (secondes), la perception de la capacité de conduire (β = 0,32), et l’évasion des situations de conduite (β = 0,55) (p <0,05). Selon cette analyse exploratoire, le ralentissement cognitif et le dysfonctionnement exécutif semblent être associés aux capacités à conduire perçues d'être modestement inférieurs et à l’évitement accru des situations de conduite au fil du temps.

Using group-aggregated results and snapshot assessments of cognitive performance may prove problematic if the assessed construct shows substantial and rapid variation over time. To illustrate the significance of this issue, we analyzed cognitive performance data of ten older adults undergoing daily computerized cognitive assessments (CogState Brief Battery) for 36–93 days. In all cases, the day-to-day intra-individual variability was substantial when compared with group-level, between-person variability. This indicates that the results of studies using single snapshot assessments of cognitive functioning should be interpreted with caution. Additionally, group-aggregated measures of cognitive performance may not directly extrapolate to an individual.
