This randomized controlled trial investigated the acute effects of aerobic exercise (AE) and combined aerobic and cervical-upper extremity resistance exercise (CE) on the pressure pain threshold (PPT), pain perception, and fatigue in workers with high ergonomic risk and chronic non-specific neck pain (CNNP). A total of 78 workers were randomly assigned to AE, CE, or control groups. The AE and CE groups completed single 40-minute sessions, while the control group received a 30-minute educational session with additional seated rest periods before and after the session. PPT was assessed bilaterally at multiple anatomical sites using a digital pressure algometer. Neck pain, overall pain perception, and fatigue were evaluated using a numerical rating scale (NRS) before, immediately after, and 20 minutes after exercise. The study focused on exercise-induced hypoalgesia (EIH) and was intended to inform brief, workplace-compatible exercise strategies to reduce pain, fatigue, and work-related musculoskeletal risks in this population.
