“…Performing a cognitive task after exercise is potentially ideal as it takes advantage of the heightened cortical activity during recovery. Twenty to 30 min of moderate intensity (50-60% VO 2max ) cycling increased post-exercise cortical oxygenation (i.e., activation), which aligned with improvements in post-exercise executive function performance (Stroop task) (Yanagisawa et al, 2010;Stavres et al, 2017;Tsubaki et al, 2018). Increased PFC oxygenation may be indicative of higher cortical activity and, therefore, greater mental effort leading to improved cognitive processes such as working memory and attention (Herold et al, 2018).…”

Acute Aerobic Exercise Based Cognitive and Motor Priming: Practical Applications and Mechanisms

Acute exercise stimulates brain regions involved in motor and cognitive processes. Recent research efforts have explored the benefits of aerobic exercise on brain health and cognitive functioning with positive results reported for both healthy and neurocognitively impaired individuals. Specifically, exercise positioned near therapeutic (both behavioral and physical) activities may enhance outcomes associated with treatment outcomes (e.g., depression or motor skill) through neural plasticity promoting mechanisms (e.g., increased brain flow and oxygenation). This approach has been termed "exercise priming" and is a relatively new topic of exploration in the fields of exercise science and motor control. The authors report on physiological mechanisms that are related to the priming effect. In addition, parameters related to the exercise bout (e.g., intensity, duration) and the idea of combining exercise and therapeutic rehabilitation are explored. This exercise-based priming concept has the potential to be applied to many areas such as education, cognitive therapy, and motor rehabilitation.

“…Upon cessation of low-moderate intensity aerobic exercise, cerebral oxygenation remains elevated for up to 30 min (Faulkner et al, 2016;Stavres et al, 2017;Tsubaki et al, 2018). Performing a cognitive task after exercise is potentially ideal as it takes advantage of the heightened cortical activity during recovery.…”

“…A previous study indicated that alteration in CBF, assessed by MCA blood flow velocity, was not directly associated with alteration in cognitive performance during exercise under hypoxia. 22,23 However, CBF is heterogeneously distributed in the brain under severe hypoxia. 84,85 In contrast, during exercise, increases in cerebral metabolism increase CBF to maintain oxygen delivery for aerobic metabolism.…”

“…In follow-up studies, Komiyama et al 21 reported cognitive improvement in the GNG and spatial delayed response tasks during moderate exercise in moderate hypoxia and severe hypoxia. 22 Seo and colleagues [23][24][25] examined the combined effects of moderate exercise and in severe hypoxia in both male 23,24 and female 23,25 participants. The same group reported cognitive improvement in memory [23][24][25] and mathematical performance, 23 but not in the GNG task.…”

Acute moderate intensity exercise has been shown to improve cognitive performance. In contrast, hypoxia is believed to impair cognitive performance. The detrimental effects of hypoxia on cognitive performance are primarily dependent on the severity and duration of exposure. In this review, we describe how acute exercise under hypoxia alters cognitive performance, and propose that the combined effects of acute exercise and hypoxia on cognitive performance are mainly determined by interaction among exercise intensity and duration, the severity of hypoxia, and duration of exposure to hypoxia. We discuss the physiological mechanism(s) of the interaction and suggest that alterations in neurotransmitter function, cerebral blood flow, and possibly cerebral metabolism are the primary candidates that determine cognitive performance when acute exercise is combined with hypoxia. Furthermore, acclimatization appears to counteract impaired cognitive performance during prolonged exposure to hypoxia although the precise physiological mechanism(s) responsible for this amelioration remain to be elucidated. This review has implications for sporting, occupational, and recreational activities at terrestrial high altitude where cognitive performance is essential. Further studies are required to understand physiological mechanisms that determine cognitive performance when acute exercise is performed in hypoxia.

Highlights Exposure to hypoxia impaired attentional ability, executive function, and memory function but not information processing. The effects of hypoxia on cognition were significantly moderated by sex and cognitive task type but not by other variables. Performing exercise under a hypoxia setting has significant effects on cognitive improvement, which was moderated by cognitive task type, exercise type, exercise intensity, training type, and hypoxia level.
