• Greenhouse cucumber workers have been evaluated. • Cucumber cultivation tasks have been identified. • The back and legs are the parts of the body most affected during work. • Warm-up exercises are recommended before starting the workday. Work-related musculoskeletal disorders (MSDs) are very common in the agricultural sector because most tasks are manual. This study attempts to analyse the forced postures and repetitive movements in greenhouse cucumber workers. Two semi-quantitative assessment methods (Ovako Working Analysis System and Rapid Upper Limb Assessment) were used following an exhaustive field analysis of the work. The results indicate the need to avoid continuous back flexion, leg flexion and arm elevation. The tasks with the highest risk of MSDs are T1 (transplant furrow) and T4 (planting seedlings), which carry a 46% and 72% level-3 risk, respectively. Postural training for workers, mechanising tasks, and improving their physical state could reduce the risk of MSD.
