    Time-Dependent Effects of Acute Exercise-Induced Arousal on Long-Term Memory for Emotional and Neutral Stimuli
    (2016) Weiss, Lauren Rachel; Smith, J. Carson; Kinesiology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Psychological research has strongly documented the memory-enhancing effects of emotional arousal, while the effects of acute aerobic exercise on memory are not well understood. Manipulation of arousal has been shown to enhance long-term memory for emotional stimuli in a time-dependent fashion. This presents an opportunity to investigate the role of acute exercise in memory modulation. The purpose of this study was to determine the time-dependent relationship between acute exercise-induced arousal and long-term emotional memory. Participants viewed pleasant, neutral, and unpleasant images before or after completing a high-intensity session of cycling exercise. Salivary alpha-amylase, a biomarker of central norepinephrine, was measured as an indicator of arousal. No effects of exercise on recognition memory were revealed, however; a single session of high-intensity cycling increased salivary alpha-amylase. Our results also indicate that the influence of exercise on emotional responsiveness should be considered in further exploration of the memory-enhancing potential of acute exercise.

    THE EFFECTS OF AN ACUTE BOUT OF EXERCISE UPON BEHAVIORAL RESPONSES TO AND NEUROPHYSIOLOGICAL INDICES OF ATTENTION ALLOCATION IN CHILDREN AND ADULTS
    (2014) Cipriani, Kristin; Clark, Jane E.; Kinesiology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    In both child and adult populations, engagement in frequent physical activity results in a myriad of cognitive benefits, including improved executive functioning. However, the relationship between engagement in acute bouts of physical activity and cognitive processes, such as attention allocation, are less well understood. Methods: This study sought to: 1) Investigate the effects of an acute bout of exercise on behavioral responses; 2) Investigate the effects of an acute bout of exercise on neurophysiological measures; and, 3) Investigate age-related differential effects. EEG was recorded from 32 male participants (n=16 adults, n=16 children 9-11 years of age) who completed a 3-stimulus auditory oddball behavioral task, pre- and post-exercise intervention. Results: Contrary to expectations, this study found that, regardless of age, engagement in an acute bout of exercise did not have a significant effect upon some behavioral and all neurophysiological indices of attention, as measured by response accuracy, reaction time percent difference, and P3a and P3b amplitude, respectively. Moreover, the findings indicate no age-related differential effects of acute exercise on these same indices of attention. However, absolute reaction time results indicate a significant main effect for group (F (1, 21) =4.48, p<0.05) in the block immediately following the acute exercise intervention. Discussion: The relative ease with which both adult and child participants completed the behavioral task indicates that the task may have been simple, rather than executive in nature. Therefore, only some of the behavioral benefits and none of the typical neurophysiological benefits associated with acute exercise bouts were seen in this study, nor were age-related differential effects of acute exercise observed. However, the significant difference in reaction time between intervention and control groups immediately following the intervention, does provide the behavioral results typical of this intervention. Future studies should explore similar acute exercise interventions in combination with a varied behavioral task (e.g., a modified 3-stimulus auditory oddball) that strongly activates the executive functioning network.
