Introduction: Engaging in health-enhancing physical activity (HEPA) can reduce the risk of developing chronic diseases, which is particularly important for office workers with sedentary lifestyles. Therefore, time- and location-independent interventions for increasing HEPA are necessary.
Methods: To achieve long-term changes in HEPA, interventions can be based on physical activity-related health competence (PAHCO). 48 office workers (83% female, 50 ± 8 years) completed an intervention consisted of bi-weekly exercise videos for five weeks, supplemented by PAHCO and anatomical education. The participants' HEPA levels were measured using the BSA-F questionnaire and a physical activity diary, with follow-up measurements at three months.
Results: There was a significant increase in PAHCO (p = .002), especially in control competence (p < .001), after the intervention and at follow-up. The other sub-competences also increased, but not significantly. HEPA decreased after the intervention and at follow-up, but the decrease was not statistically significant.
Discussion: The study indicates that the intervention can improve PAHCO in a real-world setting. However, its impact on actual HEPA levels is inconclusive, requiring further research with a more robust design and objective PA measures.
