Article Abstract

Objective: To evaluate the effects of bilateral dorsolateral prefrontal cortex high-definition transcranial direct current stimulation (HD-tDCS) on glycemic excursions during a time-trial performance in elite cyclists with type 1 diabetes (T1D).

Methods: In a double-blind, randomized crossover order, 9 elite cyclists with T1D (no complications) underwent either HD-tDCS (F3 and F4) or control (SHAM) and completed a constant-load trial at 75% of the second ventilatory threshold plus a 15-km cycling time trial.

Results: Real-time continuous glucose monitoring revealed similar glycemic variability between the 2 conditions, showing a significant effect of time but no interaction (stimulation × time) or stimulation effect.

Conclusion: Because glycemic control is crucial for both health and performance, these findings suggest that HD-tDCS could be safely used to enhance performance in athletes with T1D and potentially in a broader active T1D population.

Optimal body mass normalization of power output for accurate prediction of estimated cycling performance over complex time-trial courses.

Introduction: Power profiling is widely used in cycling performance analysis, but both absolute and mass-normalized power outputs have limitations as performance indicators, as they neglect external factors such as terrain, wind, aerodynamic drag, and pacing strategy. To address these limitations, this study introduced a numerical method to quantify how external forces acting on the cyclist influence the conversion of power output into race velocity. Thus, the study aimed to enable accurate prediction of cycling performance based on estimated mean power output over complex time-trial courses.

Introduction: While physiological predictors like maximal oxygen uptake and lactate threshold are well established in cycling, psychological factors such as affective load and effort perception remain less studied.

Purpose: The aim of this study was to explore the possible differences in psychophysiological responses between professional and national-level cyclists during a race simulation.

Methods: Twenty-four male cyclists (12 professionals and 12 national level) matched for V˙O2max (75.

Repeated-sprint training in hypoxia (RSH) is increasingly used by athletes to improve repeat sprint ability in normoxia. However, the physiological responses to varying protocols remain unclear. This study aimed to determine how different RSH protocols affect acute physiological responses in elite cyclists.
