Effects of transcranial photobiomodulation on performance and cardiovascular responses in trained cyclists

Acute transcranial PBM did not influence cycling performance or perceptual and physiological responses in trained athletes. These findings suggest that the applied PBM parameters may have been insufficient to elicit measurable cortical or performance effects. Future research should explore optimized stimulation parameters and chronic application protocols to clarify the potential ergogenic role of PBM in endurance exercise.
