Study 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.

Read the 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 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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

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

Exclusion criteria

Exclusion Criteria:

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

Groups and cohorts

  • 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").

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 10, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
