Participants will complete a single supervised, online high intensity interval training (HIIT) exercise session lasting approximately 20 minutes.

Protocol Completion Rate
Protocol Completion Rate is defined as the proportion of enrolled participants who complete both the supervised home-based HIIT exercise session and return all scheduled saliva samples to the laboratory.
Time frame: From enrollment through completion of all study procedures (up to Day 1)
Acceptability of the Exercise and Saliva Collection Protocol
Acceptability will be assessed using a participant-reported questionnaire adapted from the Theoretical Framework of Acceptability (TFA). The questionnaire evaluates acceptability across seven domains: affective attitude, burden, perceived effectiveness, ethicality, intervention coherence, opportunity costs, and self-efficacy. Each domain is assessed using 1-2 items rated on a 5-point Likert scale (1 = strongly disagree to 5 = strongly agree). Domain scores are averaged, and an overall Acceptability Index score is calculated, with higher scores indicating greater acceptability.
Time frame: Immediately after protocol completion (Day 1)
