Abstract
Background:High psychosocial stress can impair executive function in adolescents,whereas acute exercise has been reported to benefit this cognitive domain. The aim ofthis study was to investigate whether an acute bout of aerobic exercise improves theinhibitory aspect of executive function and the associated dorsolateral prefrontal cortex(DLPFC) oxygenation when under stress.Methods:Sixty male high school students aged 16–20 years performed a Strooptask (baseline condition) and were randomly assigned to an exercise group (30 min onergometer at 70% of maximum heart rate) and a control group (30 min of reading).Subsequently, all participants underwent a modified Trier Social Stress Test, whichincluded a Stroop task under enhanced stress. The Stroop tasks in both conditionswere combined with functional near-infrared spectroscopy to record changes in DLPFCoxygenation in response to the tasks. Stress reactivity was measured with salivasamples (cortisol, alpha-amylase), heart rate monitoring, and anxiety scores.Results:All stress parameters indicated increases in response to the stressor(p<0.001), with higher alpha-amylase [t(58) =−3.45,p= 0.001,d= 1.93] andanxiety [t(58) =−2.04,p= 0.046,d= 0.53] reactions in the control compared to theexercise group. Controlling for these two parameters, repeated measures analyses ofcovariance targeting changes in Stroop interference scores showed no main effect ofstress [F(1,58) = 3.80,p= 0.056,ηp2= 0.063] and no stress×group interaction[F(1,58) = 0.43,p= 0.517,ηp2= 0.008]. Similarly, there was no main effect ofstress [F(1,58) = 2.38,p= 0.128,ηp2= 0.040] and no stress×group interaction[F(1,58) = 2.80,p= 0.100,ηp2= 0.047] for DLPFC oxygenation.Conclusion:Our study confirms potentially health-enhancing effects of acute exerciseon some of the physiological and psychological stress reactivity indicators. However,our data do not support the notion of an effect on interference control and DLPFCactivation under stress.
