Interventions/Control_1

Participants will perform cycle ergometer exercise at 40% heart rate reserve for 30 minutes in the exercise condition, and maintain a resting state for 30 minutes in the control condition.

Interventions/Control_2

Magnetic resonance spectroscopy (MRS) will be performed after the intervention. During the MRS acquisition, mood fluctuations will be induced using the Open Affective Standardized Image Set (OASIS).
