Objectives

Narrative objectives1

Regional cerebral blood flow (CBF) is investigated after the session of high-intensity aerobic exercise so that the relationships between regional CBF and blood exerkines levels, such as irisin, BDNF and cathepsin B, which have roles for neural plasticity and neuroprotective effect, are explored.
To identify the coupling of CBF and oxygen metabolism in the prefrontal cortex (PFC), that regulates will to perform exercise and involves the underlying mechanism for mood change, the ratio of CBF to metabolic rate for oxygen (CMRO2) is analyzed by simultaneous measurements using PET and near infrared spectroscopy, which enables to calculate CMRO2 applying cerebral hemoglobin oxygen saturation. We also clarify exercise-related self-efficacy, state of stress and fatigue and personal characteristics in traits that are related with mood change induced by exercise.

Primary outcomes

Regional CBF, CMRO2 in the prefrontal cortex, blood exerkines levels (BDNF, irisin and cathepsin B etc.), mood change (measured by scaling scores)

Key secondary outcomes

Respiratory variables (minute ventilation, partial pressure of arterial carbon dioxide), circulatory dynamics (heart rate, blood pressure), participants' exercise self-efficacy, personality traits, and perceived exertion during exercise
