“…In summary, while an increasing body of work has compared stationary conditions to light exercise, or continuous walking (Bullock et al, 2017; Cao & Händel, 2019; Chen et al, 2022a, 2022b; Cortney Bradford et al, 2019; Garrett et al, 2021), we have demonstrated that reliable measurements can be made within the stride cycle. In the current paper, this has revealed clear changes in visual performance linked to the phase of the stride cycle.…”

“…Others have focused on how the presence of a dual-task during walking affects gait parameters such as speed and variability (Al-Yahya et al, 2011). More recent reports have demonstrated that walking or light exercise can enhance visual processing relative to stationary conditions (Bullock et al, 2017; Cao & Händel, 2019; Chen et al, 2022a, 2022b; Dodwell et al, 2021; Garrett et al, 2021). These results echo earlier work in animal models which has demonstrated how locomotion elevates the response gain of early visual processing areas – potentially providing a mechanism for enhanced performance on visual processing tasks (Ayaz et al, 2013; Busse et al, 2017; Dipoppa et al, 2018; Niell & Stryker, 2010; Parker et al, 2020).…”

Walking is among our most frequent and natural of voluntary behaviours, yet the consequences of locomotion upon perceptual and cognitive function remain largely unknown. Recent work has highlighted that although walking feels smooth and continuous, critical phases exist within each step-cycle for the successful coordination of perceptual and motor function. Here, we tested whether these phasic demands impact upon visual perception, by assessing performance in a visual detection task during natural unencumbered walking. We finely sampled visual performance over the stride cycle as participants walked along a smooth linear path at a comfortable speed in a wireless virtual reality environment. At the group-level, accuracy, reaction times, and response likelihood showed strong oscillations, modulating at approximately 2 cycles-per-stride (~2 Hz) with a marked phase of optimal performance aligned with the swing phase of each step. At the participant level, Bayesian inference of population prevalence revealed highly prevalent oscillations that clustered in two idiosyncratic frequency ranges (2 or 4 cycles per stride), with a strong phase alignment across participants.

“…Second, more than half of the studies (16) used walking paradigms, whereas only 20% of the behavioral studies investigated walking. Here, only one study found a positive effect of walking ( Cao and Händel, 2019 ) and two studies found mixed effects ( Chen et al, 2022a , b ). On the other hand, out of the 13 studies that tested the effect of cycling, only two studies found detrimental effects of exercise, while the majority revealed mixed or positive results.…”

“…Half of the studies with mixed results also used pedaling [3 auditory and 1 visual ( Bullock et al, 2015 ; Zink et al, 2016 ; Scanlon et al, 2017 ; Kuziek et al, 2018 )], while two assessed walking on a treadmill [1 auditory and 1 visual ( Gramann et al, 2010 ; Ladouce et al, 2019 )] and the other two applied a visual, free walking paradigm ( Chen et al, 2022a , b ). Comparing 20 min of light or high-intensity exercise to rest, Bullock et al (2015) found no modulation of the P300 amplitude, but earlier P300 peak latencies.…”

During the last 30 years, a large number of behavioral studies have investigated the effect of simultaneous exercise on cognitive functions. The heterogeneity of the results has been attributed to different parameters, such as intensity or modality of physical activity, and the investigated cognitive processes. More recent methodological improvements have enabled to record electroencephalography (EEG) during physical exercise. EEG studies combining cognitive tasks with exercise have described predominantly detrimental effects on cognitive processes and EEG parameters. However, differences in the underlying rationale and the design of EEG versus behavioral studies make direct comparisons between both types of studies difficult. In this narrative review of dual-task experiments we evaluated behavioral and EEG studies and discuss possible explanations for the heterogeneity of results and for the discrepancy between behavioral and EEG studies. Furthermore, we provide a proposal for future EEG studies on simultaneous motion to be a useful complement to behavioral studies. A crucial factor might be to find for each cognitive function the motor activity that matches this function in terms of attentional focus. This hypothesis should be investigated systematically in future studies.
