This study involves healthy male physical education students aged 18–29 years with no cardiovascular, pulmonary, metabolic, neurological, musculoskeletal, or visual disorders. The research does not study a specific disease but examines neuromodulation effects on endurance and cognitive performance in a healthy, physically active population..
Conditions
Interventions
Intervention 1: Intervention group 1: Participants will receive anodal transcranial direct current stimulation (tDCS) over the left dorsolateral prefrontal cortex (L-DLPFC) with the anode at F3 and t
however, current will be delivered for only the first 30 seconds and then stopped, mimicking the sensation without providing actual stimulation.

Design outcomes

| Measure | Time frame |
|---|---|
| The primary outcome variable is the endurance performance, specifically measured as the time to exhaustion on ergometer cycling test. This is the main variable expected to change as a result of the interventions (tDCS, tPCS, or sham), and it is the outcome used for calculating the sample size. Timepoint: The primary outcome (endurance performance – time to exhaustion) is measured once in each experimental session, immediately after the application of the intervention (tDCS, tPCS, or sham). There is no multiple follow-up measurements planned — the timepoint is directly after intervention within the same session. Method of measurement: The primary outcome variable, namely endurance performance, will be assessed using a cycling test time to exhaustion on a cycle ergometer (Cyclus). During the initial session, participants’ peak power output will be determined by performing an incremental exercise test. In the three main experimental sessions, participants will be required to cycle at 85% of their determined peak power output until exhaustion, and the time to exhaustion will be recorded as the indicator of endurance performance. | — |
