Runners with better cardiorespiratory fitness had higher prefrontal cortex activity during both single and exercise-executive function dual tasks: an fNIRS study

چکیده
Objective: This study investigated the relationship between executive function and prefrontal cortex oxygenation during exercise in young adults with different Cardiorespiratory fitness (CRF) levels. Methods: A total of 28 amateur runners ( n = 14) sedentary college students were recruited. The maximum oxygen uptake estimated for sub-maximal intensity run (4.97 miles/h) was used to indicate CRF After 1 week, participants must complete Stroop 2-Back tasks silence while performing moderate-intensity exercise. Using 19-channel functional near-infrared spectroscopic (fNIRS) examine changes oxyhemoglobin. Results: There no significant difference correctness two groups exercise, but runner group showed an acceleration reaction time. fNIRS results that task, left dorsolateral oxyhemoglobin higher than group. Conclusion: Executive similarly improved better fitness, suggesting provides excellent metabolic reserve directed allocation cognitive

Higher levels of cardiovascular fitness are associated with better executive function and prefrontal oxygenation in younger and older women
AIM Many studies have suggested that physical exercise training improves cognition and more selectively executive functions. There is a growing interest to clarify the neurophysiological mechanisms that underlie this effect. The aim of the current study was to evaluate the neurophysiological changes in cerebral oxygenation associated with physical fitness level and executive functions. METHOD...
متن کاملImproved cerebral oxygenation response and executive performance as a function of cardiorespiratory fitness in older women: a fNIRS study
Cardiorespiratory fitness has been shown to protect and enhance cognitive and brain functions, but little is known about the cortical mechanisms that underlie these changes in older adults. In this study, functional near infrared spectroscopy (fNIRS) was used to investigate variations in oxyhemoglobin [HbO2] and in deoxyhemoglobin [HHb] in the dorsolateral prefrontal cortex (DLPFC) during the p...
متن کاملCardiorespiratory Fitness Is Associated with Better Executive Function in Young Women.
PURPOSE A positive association between cardiorespiratory fitness (CRF) and cognitive function has been demonstrated mainly in children and older adults. Women attending college live in a cognitively demanding setting where optimal cognition matters but often experience declines in CRF. Our aim was to test whether CRF is associated with executive function in young adult women. METHODS Particip...
متن کاملLess Effort, Better Results: How Does Music Act on Prefrontal Cortex in Older Adults during Verbal Encoding? An fNIRS Study
Several neuroimaging studies of cognitive aging revealed deficits in episodic memory abilities as a result of prefrontal cortex (PFC) limitations. Improving episodic memory performance despite PFC deficits is thus a critical issue in aging research. Listening to music stimulates cognitive performance in several non-purely musical activities (e.g., language and memory). Thus, music could represe...
متن کاملMusic improves verbal memory encoding while decreasing prefrontal cortex activity: an fNIRS study
Listening to music engages the whole brain, thus stimulating cognitive performance in a range of non-purely musical activities such as language and memory tasks. This article addresses an ongoing debate on the link between music and memory for words. While evidence on healthy and clinical populations suggests that music listening can improve verbal memory in a variety of situations, it is still...
