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.

Recent studies show positive effects of acute exercise on language learning in young adults with lower baseline learning abilities; however, this is yet to be investigated in older adults. This study investigated the acute effects of different exercise intensities on new word learning in healthy older adults with lower and higher baseline learning abilities. Sixty older adults (mean age = 66.4 (4.6); 43 females) performed either a single bout of stretching exercise, moderate-intensity continuous exercise, or high-intensity interval exercise followed by a word learning task. In lower baseline learners, between-group differences were observed on immediate new word recall success, with the moderate-intensity continuous exercise group performing better than the stretching group. These findings suggest immediate benefits of moderate-intensity continuous exercise that are limited to word learning performance of older adults with lower baseline learning abilities. Further investigation into underlying mechanisms could lead to a better understanding of individual differences in responding to acute exercise.

Predictive Role

This project concerns new analyses based on pre-existing data from a randomized controlled multicomponent intervention study combining physical exercise and cognitive training in healthy older adults. The project tests the predictive role of cardiorespiratory fitness, physical activity and pulse pressure for learning in a working memory training context, in combination with physical exercise and in isolation. Specifically, two learning outcomes are considered: change in trained working memory tasks from before to after the intervention period (pre-post change) and day-by-day change in n-back performance during the intervention period (up to 32 timepoints). The results did not support a predictive role of cardiorespiratory fitness, physical activity or pulse pressure for learning in this particular study context.

Acute bouts of exercise have been shown to improve fine motor control performance and to facilitate motor memory consolidation processes in young adults. Exercise effects might be reflected in EEG task-related power (TRPow) decreases in the beta band (13–30 Hz) as an indicator of active motor processing. This study aimed to investigate those effects in healthy older adults. Thirty-eight participants (65–74 years of age) were assigned to an experimental (EG, acute exercise) or a control group (CG, rest). Fine motor control was assessed using a precision grip force modulation (FM) task. FM performance and EEG were measured at (1) baseline (immediately before acute exercise/rest), (2) during practice sessions immediately after, (3) 30 minutes, and (4) 24 hours (FM only) after exercise/rest. A marginal significant effect indicated that EG revealed more improvement in fine motor performance immediately after exercise than CG after resting. EG showed enhanced consolidation of short-term and long-term motor memory, whereas CG revealed only a tendency for short-term motor memory consolidation. Stronger TRPow decreases were revealed immediately after exercise in the contralateral frontal brain area as compared to the control condition. This finding indicates that acute exercise might enhance cortical activation and thus, improves fine motor control by enabling healthy older adults to better utilize existing frontal brain capacities during fine motor control tasks after exercise. Furthermore, acute exercise can act as a possible intervention to enhance motor memory consolidation in older adults.

The Relationship

Background: Relatively little is known regarding the association between objective measures of physical function such as cardiorespiratory fitness (CRF) and cognitive function tests in healthy older adults. Objective: To evaluate the relationship between CRF and cognitive function in adults aged 55 and older. Methods: Between 2008 and 2017, 4,931 men and women underwent a comprehensive preventive physical exam at the Cooper Clinic in Dallas, Texas. CRF was determined by duration of a maximal treadmill exercise test. Cognitive function was evaluated with the Montreal Cognitive Assessment (MoCA). In a multivariate model, adjusted odds ratios with 95% confidence intervals for MoCA scores < 26 (i.e., cognitive impairment) were determined by using CRF as both a continuous and a categorical variable. Results: The mean age of the sample was 61.0 ± 6.0 years; mean maximal MET values were 10.0 ± 2.2. Mean MoCA scores were 26.9 ± 2.2; 23.4% of the sample had MoCA scores indicative of cognitive impairment. The odds ratio for cognitive impairment was 0.93 (0.88–0.97) per 1-MET increment in CRF. When examined as a categorical variable, and using the lowest CRF quintile as the referent, there was a significantly reduced likelihood for cognitive impairment across the remaining ordered CRF categories (p trend = 0.004). Conclusion: The association between CRF and MoCA score in older adults suggests that meeting or exceeding public health guidelines for physical activity is likely to increase CRF in low fit individuals, maintain CRF in those with a moderate to high level of CRF, and thereby help to maintain cognitive function in healthy older adults.
