HYPOXIA
Within the 3rd to 6th sessions, after 30 min performing CWST, followed by 20 min of tDCS, participants performed the TTE on a cycle ergometer (Cyclus 2, RBM Elektronik-Automation GmbH, Leipzig, Germany), all under hypoxia. Before TTE, participants warmed up cycling for 5 min at 45% PPO. After warming up, TTE started with a load of 60% of PPO and a 60 rpm cadence until exhaustion. The time between the beginning and interruption of the test was considered the TTE. HR and SpO
