Figure 1. Experimental design: (A) Stroop test (neutral task and incongruent task); (B) tissue oxygen index (TOI) measurement in the prefrontal cortex (PFC) during the Stroop test; (C) control (CON), high-intensity resistance exercise (HIR; 7 exercises, 3 sets, 8–10 reps), combined moderate-intensity exercise (MIC; 7 exercises, 3 sets, 12 reps, and 30 min walking), high-intensity aerobic exercise (HIA; 30 min running). Resistance exercise comprised leg extension, lat pull down, leg curl, seated row, half squat, chest press, and arm curl.
