Inclusion criteria
Inclusion criteria: Participants will be eligible for inclusion if they meet all of the following criteria: 1.Aged 18–35 years; 2.Currently enrolled as a full-time or part-time undergraduate, master’s student, or doctoral student at a regular institution of higher education; 3.Voluntarily agrees to participate, is able to understand the study procedures, potential risks, and participant rights, and provides written informed consent; 4.Able to wear an accelerometer continuously for seven days as required and provide valid data meeting the prespecified quality-control criteria; 5.Average sedentary time over seven days accounts for more than 50% of valid accelerometer wear time; 6.Deemed physically suitable for moderate-intensity exercise following exercise-safety screening; 7.Able to understand and complete the 2-back, Stroop, and WCST-like executive-function tasks; 8.Able to cooperate with and complete the two formal exercise-intervention sessions and the required pre- and post-exercise EEG assessments; 9.Agrees to comply with the prespecified requirements regarding sleep, exercise, alcohol consumption, and caffeine intake before both experimental sessions; 10.Able to maintain relatively stable daily routines and physical-activity habits during the study period.
Exclusion criteria
Exclusion criteria: Participants will be excluded if they meet any of the following criteria: 1.Invalid accelerometer data, insufficient valid wear days or valid wear time, or an average sedentary proportion of no more than 50% over seven days; 2.Cardiovascular, cerebrovascular, respiratory, metabolic, or other serious disease identified through interview or health screening that makes moderate-intensity exercise unsuitable; 3.Recent acute injury, significant musculoskeletal pain, joint instability, or another condition that interferes with exergaming or cycle ergometer exercise; 4.A history of epileptic seizures, unexplained syncope, or a neurological disorder that may substantially affect EEG acquisition or exercise safety; 5.A currently uncontrolled psychiatric or psychological disorder, or insufficient cognitive, language, or comprehension ability to complete the tasks; 6.Current use of medication that may substantially affect central nervous system function, heart-rate responses, or executive-function performance and is judged by the principal investigator to affect the study results or exercise safety; 7.Scalp injury, severe skin allergy, or another condition that makes wearing the EEG cap unsuitable; 8.Visual or corrected visual acuity insufficient to complete the computerized tasks, or a significant color-vision abnormality that interferes with completion of the Stroop task; 9.Unable to complete both experimental sessions at the scheduled times or explicitly unable to comply with the pre-experiment control requirements; 10.Concurrent participation in another interventional study that may affect physical activity, cognitive function, or EEG outcomes; 11.Considered unsuitable for participation by the principal investigator on safety grounds.
