Exercise and Health Education for Textile Workers: A Pre-Post Study

The protocol uses a quasi-experimental, single-group pre-post design without a control group, conducted in a real occupational setting. All participants will undergo an 8-week intervention program, followed by a 4-week follow-up period. The intervention adopts a hybrid format, combining face-to-face sessions at the workplace with asynchronous online exercise sessions delivered through a mobile application. Prior to the intervention, participants will undergo a comprehensive baseline assessment to allow for individualized exercise prescription. The same assessment protocol will be repeated at the end of the 8-week intervention and again at the 4-week follow-up. The intervention includes: Eight on-site workshops (one per week during working hours), addressing topics such as musculoskeletal pain management, self-efficacy, physical exercise, mobility, stress management, sleep hygiene, and healthy lifestyle habits. Two weekly online exercise sessions, delivered asynchronously via a digital platform, focusing on mobility, core stability, and progressive strengthening of the upper and lower limbs and spinal stabilizing muscles. Exercise programs will be progressive and adapted to participants' perceived exertion and functional capacity. Adherence will be monitored through attendance records and digital tracking of completed exercise sessions. Participants must complete at least 80% of the intervention to be included in the final analysis. Outcome measures include perceived pain intensity, musculoskeletal symptom prevalence, upper and lower limb muscle strength, physical activity level, work ability, sleep quality, psychosocial factors (stress, anxiety, and depression), health-related quality of life, and work productivity and absenteeism. All measurements are performed using validated instruments and standardized protocols.
