Purpose This study evaluated the effect of functional jackets designed to reduce the workload on the upper extremities and boost the muscle strength of workers from prolonged repetitive work.Design/methodology/approach The functional jacket designs for the upper limb incorporated a dynamic taping line with an elastic band, three-dimensional support for the abdomen and posterior waist (S2) and an X-shaped line on the scapular region combined with abdominal and posterior waist support (S3). Clothing pressure was adjusted ergonomically for different areas. A standard jacket served as the control (S1). The designs were evaluated based on work posture, electromyography and subjective sensation.Findings S2 and S3 effectively reduced the workload on the upper extremities by decreasing the trapezius muscle, shoulders and waist movement. S3 showed a low muscle-activation level on electromyogram analysis and was excellent in subjective sensation.Originality/value A functional jacket with optimal compression applied differentially to the upper extremities, with three-dimensional abdominal and posterior waist support and an X-shaped line on the scapula region, can reduce the workload on the upper extremities and boost the core muscle strength to improve work performance.
