Study Arms (1)

Employee

Employees of Kaohsiung Medical University, including faculty and administrative staff. Participants are adults (≥20 years) currently working full-time or part-time at the university. This group is selected because prolonged sedentary work and job-related demands are associated with musculoskeletal discomfort, stress, and reduced physical activity. They represent the target population for evaluating the feasibility and effectiveness of brief workplace exercise interventions ("exercise snacks").

Eligibility Criteria

• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

This study will recruit full-time faculty and staff from a university and its affiliated hospital. The participants are generally healthy adults who may experience varying levels of musculoskeletal discomfort or reduced physical fitness due to prolonged sedentary or standing work conditions. Individuals are expected to be capable of independent physical activity and willing to engage in brief, self-directed exercise sessions integrated into their daily routine.

You may qualify if:

• Currently employed at Kaohsiung Medical University or Kaohsiung Medical University Hospital.
• Willing to participate in a 12-week exercise intervention, complete related questionnaires, and undergo physical performance assessments.

You may not qualify if:

• Pregnant individuals, due to safety concerns related to exercise intensity and physical assessments.
• Individuals with a diagnosed neurological disorder (e.g., stroke, Parkinson's disease).
• Individuals experiencing severe pain in the upper or lower limb joints that interferes with their ability to complete the assessments.
• Individuals assigned to high-intensity exercise who have unstable cardiac conditions (e.g., angina, myocardial infarction, heart failure).
