finished the intervention. The comparison between the initial and final results obtained after the administration of the tests indicated that self-paced cycling had a significant impact on the participants’ global cognition and attention, visual scanning, and processing speed. The ANOVA showed that self

Although we are not aware of the effects of physical activity and CR on cognition-related brain activity in overweight and obese adults, studies of older adults (who have decreased brain activity) showed that aerobic exercise training improves executive functions and increases PFC activity and functional

This coordination, in turn, is believed to draw on cognitions of the team (e.g., Cannon-Bowers, Salas

The objective of this study was to gain an understanding of expert cognition in orienteering. The British orienteering squad was interviewed (N = 17) and grounded theory was used to develop a theory of expert cognition in orienteering. A task constraint identified as central to orienteering is the requirement to manage attention to three sources of information: the map, the environment, and travel. Optimal management is constrained by limited processing resources. However, consistent with the research literature, the results reveal considerable adaptations by experts to task constraints, characterized primarily by various cognitive skills including anticipation and simplification. By anticipating the environment from the map, and by simplifying the information required to navigate, expert orienteers can circumvent processing limitations. Implications of this theory for other domains involving navigation, and for the coaching process within the sport, are discussed.

This pilot study was designed to test the efficacy of a physical activity program for improving psychological variables and fibromyalgia syndrome (FMS) symptoms and to provide preliminary evidence regarding the effects on perceived cognitive symptoms and objectively measured cognitive performance by FMS patients.
Sixteen women diagnosed with FMS were randomly assigned to an 18-week physical activity program or to a control condition. Psychological measures, FMS symptoms, perceived cognitive function, objective measures of cognition, and walking capacity were assessed at baseline and post-test.
At posttest, there were significant differences in fatigue (effect size, ES = 1.86), depression (ES = 1.27), FMS symptoms (ES = 1.56), self-reported cognitive symptoms (ES = 1.19), and delayed recall performance (ES = 1.16) between the physically active group and the control group, indicating that the FMS patients benefited from physical activity. Beneficial effects were also observed for 6 of the 7 objective measures of cognition and ranged from small to large (ESs = 0.26 to 1.06).
Given that all FMS patients do not respond well to conventional treatments, these beneficial effects of physical activity are important. Future studies with larger samples are warranted to test the reliability of the findings for the objective measures of cognition.

The purpose of this article is to review the potential of Tai Chi Chuan as a mode of physical activity that could have cognitive benefits for older adults and to provide potential directions for future research. A brief introduction to Tai Chi Chuan and its related physical benefits is provided. In addition, the empirical literature related to Tai Chi Chuan and cognition is reviewed. Potential mediators of the relationship between Tai Chi Chuan and cognition, including physical resources, disease status, and mental resources, are discussed. Based on the limitations of the extant literature, it is argued that future research in this area must provide more detailed descriptions of Tai Chi Chuan, particularly in terms of intensity and program progression. Consideration of the specific type of cognition that is expected to benefit is also encouraged, and approaches for further efforts to understand how Tai Chi Chuan affects cognition are recommended.

Decisions to perform moderate-to-vigorous physical activity (MVPA) involve behavioral cognitive processes that may differ within individuals depending on the situation.
Ecological momentary assessment (EMA) was used to examine the relationships of momentary behavioral cognitions (ie, self-efficacy, outcome expectancy, intentions) with MVPA (measured by accelerometer). A sample of 116 adults (mean age, 40.3 years; 72.4% female) provided real-time EMA responses via mobile phones across 4 days. Multilevel models were used to test whether momentary behavioral cognitions differed across contexts and were associated with subsequent MVPA. Mixed-effects location scale models were used to examine whether subject-level means and within-subjects variances in behavioral cognitions were associated with average daily MVPA.
Momentary behavioral cognitions differed across contexts for self-efficacy (P = .007) but not for outcome expectancy (P = .53) or intentions (P = .16). Momentary self-efficacy, intentions, and their interaction predicted MVPA within the subsequent 2 hours (Ps < .01). Average daily MVPA was positively associated with within-subjects variance in momentary self-efficacy and intentions for physical activity (Ps < .05).
Although momentary behavioral cognitions are related to subsequent MVPA, adults with higher average MVPA have more variation in physical activity self-efficacy and intentions. Performing MVPA may depend more on how much behavioral cognitions vary across the day than whether they are generally high or low.

This study examined the feasibility and effect on aerobic fitness of a 1-yr, twice-weekly, group-based moderate-intensity walking program (MI-WP, n = 77) compared with a low-intensity activity program (LI-AP, n = 75) for community-dwelling older adults with mild cognitive impairment (MCI). Thirty participants did not start a program; median attendance in the other 122 participants was 71%. Small but significant associations were observed between attendance and memory in the MI-WP and general cognition in the LI-AP. Associations were no longer significant when both groups were analyzed together. Intensity, assessed using percentage of heart-rate reserve and the Borg scale, equaled intended intensity for both programs. Aerobic fitness improved significantly in participants in the MI-WP. In conclusion, cognition was not clearly associated with attendance in the 62 participants starting the MI-WP, and average attendance was good. The intensity was feasible for participants who continued the MI-WP. The findings support the proposal that regular moderate-intensity walking improves aerobic fitness in adults with MCI.

Several studies have demonstrated that exercise helps reduce or prevent cognitive deterioration among older adults, and recent studies have further examined the effects of resistance-exercise training on cognition. The purpose of this review was to examine the role of resistance-exercise training on cognition in healthy older adults. Specifically, it describes the definition, health benefits, and the design of resistance-exercise training. The authors also review the research related to resistance exercises and cognition and found that this exercise modality may enhance specific cognitive performances. Next, they examine the potential mechanisms underlying resistance exercise and cognitive enhancement. Finally, they consider potential therapeutics and recommendations for further research on resistance-exercise training and cognition in older adults.
