Effects of upright and recumbent cycling on executive function and prefrontal cortex oxygenation in young, healthy, men
Background: The purpose of this study was to assess the acute effects of posture (upright vs. recumbent) during moderate-intensity cycle exercise on executive function and prefrontal cortex oxygenation, in young healthy adults.

Methods: Seventeen physically active men (24.6 ± 4.3y) completed two 30-minute submaximal, exercise tests (Conditions: upright and recumbent cycle ergometry). Executive function was assessed using the ‘colour’ and ‘word’ Stroop task, pre- (resting) and post-exercise. Regional oxygen saturation (rSO2) to the prefrontal cortex was continuously monitored using near-infrared spectroscopy.

Results: Significant improvements in executive function (Stroop colour and word tasks) were observed following 30 minutes of exercise, for both upright and recumbent cycling (P < .05). However, there were no differences in executive function between cycling Conditions (P > .05). A significant increase in rSO2 was recorded immediately post-exercise compared to pre-exercise for both Conditions (P < .05), with a trend (P = .06) for higher peak rSO2 following recumbent cycling compared to upright cycling (81.9 ± 6.5 cf. 79.7 ± 9.3%, respectively).

Conclusions: Although submaximal cycling exercise acutely improves cognitive performance and prefrontal oxygenation, changes in cognition are not perceived to be dependent on body posture in young, healthy men.

Abstract

Background: The purpose of this study was to assess the acute effects of posture (upright vs. recumbent) during moderate-intensity cycle exercise on executive function and prefrontal cortex oxygenation, in young healthy adults.

Methods: Seventeen physically active men (24.6 ± 4.3y) completed two 30-minute submaximal, exercise tests (Conditions: upright and recumbent cycle ergometry). Executive function was assessed using the ‘colour’ and ‘word’ Stroop task, pre- (resting) and post-exercise. Regional oxygen saturation (rSO2) to the prefrontal cortex was continuously monitored using near-infrared spectroscopy.

Results: Significant improvements in executive function (Stroop colour and word tasks) were observed following 30 minutes of exercise, for both upright and recumbent cycling (P < .05). However, there were no differences in executive function between cycling Conditions (P > .05). A significant increase in rSO2 was recorded immediately post-exercise compared to pre-exercise for both Conditions (P < .05), with a trend (P = .06) for higher peak rSO2 following recumbent cycling compared to upright cycling (81.9 ± 6.5 cf. 79.7 ± 9.3%, respectively).

Conclusions: Although submaximal cycling exercise acutely improves cognitive performance and prefrontal oxygenation, changes in cognition are not perceived to be dependent on body posture in young, healthy men.
