“…To the best of our knowledge only four studies have previously investigated the effects of tDCS on various measures of endurance performance [17–19,21]. In a previous study from our laboratory, we found no significant changes in TTF during cycling exercise when a cephalic montage was administered with a single anodal electrode over one M1 and with the cathode over contralateral prefrontal cortex [21].…”

“…Three other studies investigated the effects of an electrode montage aimed at reducing the perception of effort via the stimulation of the insular cortex (tDCS with anodal electrode over T3 and cathodal over the contralateral supraorbital area, Fp2) [17,18]. The results, however, are contrasting.…”

“…The results, however, are contrasting. Okano et al [18], reported a reduction in perception of effort and ~4% improvement in peak power output during an incremental cycling test, whereas Barwood et al, [17] did not find any perceptual or performance improvement during a cycling TTF and time trial test in the heat. Although testing and environmental differences may explain these contrasting results, further replications are needed to establish the ergogenic effect of this specific tDCS procedure.…”

“…Although not always present (Angius et al, 2015; Barwood et al, 2016), recent investigations employing ~10min of tDCS have demonstrated a significant 23% improvement in whole body cycling performance (Angius et al, 2018; Okano et al, 2015; Vitor-Costa et al, 2015). Of these studies, only one tested the effect of tDCS on corticospinal excitability and found an increased MEP area with no change in the TMS-evoked silent period following bilateral extra-cephalic tDCS over the motor cortex (Angius et al, 2018).…”

The corticospinal pathway is considered the primary conduit for voluntary motor control in humans. The efficacy of the corticospinal pathway to relay neural signals from higher brain areas to the locomotor muscle, i.e., corticospinal excitability, is subject to alterations during exercise. While the integrity of this motor pathway has historically been examined during single-joint contractions, a small number of investigations have recently focused on whole body exercise, such as cycling or rowing. Although differences in methodologies employed between these studies complicate the interpretation of the existing literature, it appears that the net excitability of the corticospinal pathway remains unaltered during fatiguing whole body exercise. Importantly, this lack of an apparent effect does not designate the absence of change, but a counterbalance of excitatory and inhibitory influences on the two components of the corticospinal pathway, namely the motor cortex and the spinal motoneurons. Specific emphasis is put on group III/IV afferent feedback from locomotor muscle which has been suggested to play a significant role in mediating these changes. Overall, this review aims at summarizing our limited understanding of how fatiguing whole body exercise influences the corticospinal pathway.

“…The field of research involving neuromodulation and different exercise model is still poor, only a few studies have verified the effect of tDCS in cycling exercise with incremental-load, 5 constant-load [8][9][10][11][12][13] or supramaximal intensity 14 . Here, we aimed to know if tDCS could improve physical performance for supramaximal intermittent cycling exercise.…”

Aims: Our purpose was to determine whether Transcranial Direct Current Stimulation (tDCS) improves performance in untrained individuals for supramaximal intermittent exercise. Methods: In a cross-over design, 11 healthy male subjects (26.8 ± 4.6 years) performed four Wingate trials after 20 minutes of anodal or sham tDCS over the left Insular Cortex (IC). For performance indexes, Relative Peak Power (RPP), Relative Average Power (RAP) and Fatigue Index (FI) were computed. Also, a Rating of Perceived Exertion (RPE) and Electromyography (EMG) signal were used to assess central and muscle fatigue development. Results: There was a significant difference over trials on all performance indexes, but there were no significant condition x trial interactions for any of the indexes. RPE increased significantly over trials, but there was no condition x trial interaction. There was no significant difference over trials on EMG for the rectus femoris and vastus medialis muscles; however, EMG decreased over trials for the vastus lateralis muscle. Furthermore, there was no condition x trial interaction on the EMG signal for any of the muscles. Conclusion: Our findings suggest that the anodal tDCS technique has no impact on physical performance, perceived exertion nor muscle fatigue development for supramaximal intermittent exercise.
