“…Here, the observed reduction in the somatosensory cortex could be potentially mitigated by exercise. Several previous studies have demonstrated the capacity of exercise to improve cognitive function (Hamer and Chida, 2008;Durrant et al, 2009;Mekari et al, 2015). Here, our data partially support the positive role of voluntary exercise on the maintenance of healthy vascular density.…”

Dysfunction in neurovascular coupling that results in a mismatch between cerebral blood flow and neuronal activity has been suggested to play a key role in the pathogenesis of Alzheimer's disease (AD). Meanwhile, physical exercise is a powerful approach for maintaining cognitive health and could play a preventive role against the progression of AD. Given the fundamental role of capillaries in oxygen transport to tissue, our pilot study aimed to characterize changes in capillary hemodynamics with AD and AD supplemented by exercise. Exploiting two-photon microscopy, intrinsic signal optical imaging, and magnetic resonance imaging, we found hemodynamic alterations and lower vascular density with AD that were reversed by exercise. We further observed that capillary properties were branch order-dependent and that stimulation-evoked changes were attenuated with AD but increased by exercise. Our study provides novel indications into cerebral microcirculatory disturbances with AD and the modulating role of voluntary exercise on these alterations.

“…although the persistence of effect of the exercise on enhancement of stroop performance is highly sensitive to the exercise intensities and significant crosstalk is existing in this regard. While most of the studies reporting the stroop performance is facilitated by the moderate exercise intensity, there are other studies showing that low to moderate intensity exercise does not alter executive functioning [9], moreover when the work load becomes heavy the reaction time in executive condition becomes slow [10].…”

“…Very recently it has been reported that, an exercise session consisting of 5 minute warm up, 20 minute of moderate intensity exercise performance and a 5 minute cool down, is also associated with improved cognition [8]. On the contrary, there are other studies reported that low to moderate intensity exercise does not alter executive functioning [9], moreover when the work load becomes heavy the reaction time in executive condition becomes slow due to lower availability of hbO 2 at various regions of brain [10]. this lack of consensus calls for further research regarding the effects of acute exercise on cognition.…”

In many recent studies, moderate intensity aerobic exercise has been shown to improve mental performance. Majority of the studies have focused on the chronic effects of exercise, while studies on the acute effe cts of exercise on cognition have started to draw growing attention of the researchers. the main objective of the present study was to establish the fact that Queens college step test (Qct), a short duration step test exercise is a useful tool for improving mental performance of young adult population. ten healthy young male adults participated for the present study. they performed following cognitive tasks i.e. simple reaction time (Srt) for measuring speed of processing, stroop task for selective attention, during before exercise, immediate after exercise and 30 minutes after exercise. the performance times were recorded and carotid pulse was also measured immediately after the exercise. the finding of the study states that there was a significant decrease in Srt, and stroop task performance time immediately after exercise, 30 minutes after

“…3,4,47 A meta-analytic review indicated that, although effect sizes are small, exercise at low intensity may have the potential to lead to beneficial effects on cognitive performance. 3 In contrast, the effects of high-intensity and exhaustive exercise (>80% maximal oxygen uptake) on cognitive performance are inconsistent, [49][50][51][52][53][54][55][56] and impaired cognitive performance was observed during high-intensity and exhaustive exercise. 53,54 A meta-analysis also suggested that moderate exercise for a duration of >20 minutes appears to improve cognitive performance.…”

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.
