Effects of Different Types of Exercise on Irisin and Cognitive Performance (Exercise-Irisin)

Low-Intensity Continuous Training (LICT): Participants ran continuously for 24 minutes at 50-60% of their MAS without breaks.

Long-interval high-Intensity Interval Training (LI-HIIT): Participants ran at a speed corresponding to 80-90% of their MAS. The protocol consisted of four 4-minute bouts, separated by 2-minute active recovery periods, during which participants ran at 50% of their MAS. This pattern totaled 24 minutes of exercise.

Short-interval high-Intensity Interval Training (SI-HIIT): Participants ran at 110-120% of their MAS for 15-second intervals, covering a pre-calculated distance during each bout. After each 15-second sprint, they rested passively for 15 seconds and returned to their starting point. This was repeated continuously for 3 minutes, constituting one set. A total of four 3-minute sets were completed, interspersed with 3-minute passive rest periods, yielding a total exercise time of 24 minutes.
