Brief Summary

To create brief exercise videos addressing physical discomfort, fitness goals, and movement skills.

To design personalized exercise menus to enhance staff adherence.

To apply the "exercise snacking" model with multiple short daily sessions and evaluate its effects on health, work performance, and exercise behavior.

Detailed Description

1. To develop brief exercise videos targeting different areas of physical discomfort (e.g., neck and shoulders, lower back, lower limbs), specific fitness goals (e.g., localized muscle stretching, targeted muscle strengthening, cardiorespiratory endurance, balance training), high-intensity interval training (HIIT), or the acquisition of specific movement skills (e.g., core stability, pelvic floor muscle contraction, and multi-directional pelvic mobility).

2. To design personalized exercise "menus" based on individual needs identified through a preliminary assessment, with the goal of improving adherence to voluntary exercise routines among staff.

3. To apply the concept of "exercise snacking" by implementing a daily routine of 3 to 8 brief exercise sessions, and to evaluate changes in staff members' physiological health, work performance, and exercise behavior after a 12-week intervention.

Study Groups

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").

No interventions assigned to this group
