Objectives: The aims of this study were (i) to examine the association between cardiorespiratory fitness and white matter volume test whether those associations differ normal-weight overweight/obese children (ii) analyze other physical components (i.e., motor muscular) volume, (iii) fitness-related in related academic performance. Methods: Data came from two independent projects: ActiveBrains project (n = 100; 10.0 ± 1.1 years; 100% overweight/obese; Spain) FITKids2 242; 8.6 0.5 36%...
Language learners must place unfamiliar words into categories, often with few explicit indicators about when and how that word can be used grammatically. Reeder, Newport, Aslin (2013) showed college students learn grammatical form classes from an artificial language by relying solely on distributional information (i.e., contextual cues in the input). Here, 2 experiments revealed healthy older adults also show such statistical learning, though they are poorer than young at distinguishing...
Higher levels of cardiorespiratory fitness (CRF) and greater amounts physical activity have been associated with lower intraindividual variability (IIV) in executive function children older adults. In the present study, we examined whether CRF, measured as maximal oxygen uptake (VO2max), daily volume moderate-to-vigorous intensity (MVPA) were IIV reaction time during performance incongruent condition Stroop task younger Further, thickness cingulate cortex was regulating context CRF or...
Consistent associations have been found between higher cardiorespiratory fitness (CRF) and indices of enhanced brain health function, including behavioral measures cognition as well neuroimaging indicators such regional volume. Several studies reported that CRF levels are associated with a larger hippocampus, yet volume memory or functional connectivity metrics remain poorly understood. Using multi-modal framework, we hierarchically examine the association hippocampal resting state (rsFC) in...
There are consistent associations between physical activity and self-perceived health. However, it is not clear whether health participation in could be accounted for by with cognitive function. In the present study, we examined functioning explain variability A sample of 204 older adults performed three tests selected from Vienna test system battery: The Determination, Cognitrone, Visual Memory tests. These measure general processing speed, attention, visual memory, respectively....
Abstract Implicit probabilistic sequence learning (IPSL) involves extracting statistical regularities from sequences of events without awareness, and is thought to underlie language behavioral repertoires everyday life. We examined whether resting-state functional connectivity networks the caudate predicted individual differences in IPSL performance measured on a separate day. Whole-brain maps bilateral dorsal (DC) seed were created for each subject voxelwise correlations with performance,...
Abstract Objective Higher levels of physical activity ( PA ) reduce the risk cognitive impairment, but underlying mechanisms are unclear. Using longitudinal data from Cardiovascular Health Study, we examined whether predicted plasma A β and for decline 9–13 years later. Methods Linear logistic regressions (controlling APOE status, age, gender, body mass index, cardiovascular disease, brain white matter lesions, cystatin C levels) tested associations between , impairment in a sample 149...
Abstract Overweight and obesity may damage the cerebrovascular architecture, resulting in a significant reduction cerebral blood flow. To date, there have been few randomized clinical trials (RCT) examining whether obesity‐related reductions flow could be modified by weight loss. Further, it is unknown behavioral intervention strategy for loss (i.e., diet alone or combined with exercise) differentially influences adults overweight obesity. The primary aim of this study was to determine...
Obesity is associated with poorer executive functioning and reward sensitivity. Yet, we know very little about whether weight loss through diet and/or increased exercise engagement improves cognitive function. This study evaluated following a dietary intervention was improved performance. We enrolled 125 middle-aged adults overweight obesity (98 female) into 12-month behavioral intervention. Participants were assigned to one of three groups: energy-restricted alone, an plus 150 min moderate...
