A Single Bout of Intermittent Hypoxia Increases Cerebral Blood Flow and Supports an Executive Function Benefit Open
Alternating between brief normoxic and hypoxic intervals (i.e., intermittent hypoxia: IH) increases cerebrovascular dilation, cerebral blood flow (CBF), and O 2 extraction. Some work has shown that the physiological adaptations arising fro…

Beyond FITT: addressing density in understanding the dose–response relationships of physical activity with health—an example based on brain health Open
Research on physical activity (PA) and health has a fundamental concern with dose–response relationships. The variables of (1) Frequency, (2) Intensity, (3) Time, and (4) Type (i.e., the FITT principle) have traditionally been used to oper…

Sub-symptom threshold aerobic exercise improves executive function during the early stage of sport-related concussion recovery Open
We examined whether persons with a sport-related concussion (SRC) derive a postexercise executive function (EF) benefit, and whether a putative benefit is related to an exercise-mediated increase in cerebral blood flow (CBF). Participants …

Effects of Physical Exercise Breaks on Executive Function in a Simulated Classroom Setting: Uncovering a Window into the Brain Open
Acknowledging the detrimental effects of prolonged sitting, this study examined the effects of an acute exercise break during prolonged sitting on executive function, cortical hemodynamics, and microvascular status. In this randomized cros…

Dietary omega-3 polyunsaturated fatty acids reduce cytochrome c oxidase in brain white matter and sensorimotor regions while increasing functional interactions between neural systems related to escape behavior in postpartum rats Open
Introduction Previously, we showed that omega-3 polyunsaturated fatty acid n-3 (PUFA) supplementation improved the performance of postpartum rats in the shuttle box escape test (SBET). Methods The brains of these rats were used in the curr…

Passive exercise provides a simultaneous and postexercise executive function benefit Open
Introduction Passive exercise involves limb movement via an external force and is an intervention providing an immediate postexercise executive function (EF) benefit. It is, however, unknown whether EF is improved simultaneous with passive…

Acute stress imparts a transient benefit to task-switching that is not modulated following a single bout of exercise Open
Introduction Cognitive flexibility represents a core component of executive function that promotes the ability to efficiently alternate—or “switch”—between different tasks. Literature suggests that acute stress negatively impacts cognitive…

Improving executive function: Does the intensity of a single bout of aerobic exercise matter? Open
A single bout of moderate-to-heavy intensity aerobic exercise benefits executive function. Here, we examined whether and intensity aerobic exercise provide a benefit to executive function similar to intensity. A cross-over counterbala…

Pupillometry Reveals the Role of Arousal in a Postexercise Benefit to Executive Function Open
A single bout of aerobic exercise improves executive function; however, the mechanism(s) underlying this improvement remains unclear. Here, we employed a 20-min bout of aerobic exercise, and at pre- and immediate post-exercise sessions exa…

Increased cerebral blood flow supports a single-bout postexercise benefit to executive function: evidence from hypercapnia Open
Single-bout aerobic exercise “boosts” executive function, and increased cerebral blood flow (CBF) has been proposed as a mechanism for the benefit. In this study, participants completed 10 min of aerobic exercise and 10 min of inhaling a h…

Alternating Between Stimulus-Driven and Minimally-Delayed Prosaccades: Switch-Costs Manifest via Response Suppression Open
A salient feature of executive function is the ability to rapidly alternate between tasks to allow online reconfiguration of attentional and motor goals. Notably, task-switching efficiency is asymmetrically dependent on the demands of the …

Older adults elicit a single-bout post-exercise executive benefit across a continuum of aerobically supported metabolic intensities Open
Ten minutes of aerobic or resistance training can 'boost' executive function in older adults. Here, we examined whether the magnitude of the exercise benefit is influenced by exercise intensity. Older adults (N = 17: mean age = 73 years) c…
