M0625 102 12th International Scientific Conference on the Prevention of Work-Related Musculoskeletal Disorders PREMUS 2025 Oral PS 22 Tübingen 20250909 20250912 102 TextIntroduction: Determinations of human muscle mass demonstrate the background to the prevention of musculoskeletal disorders in employees exposed to increased physical stress. In German-speaking countries, F. W. Theile was the first scientist since ancient times to present muscle mass measurements from human autopsies. Today, a wide range of methods is available. What benefits can we derive from this for occupational medicine?Methods: Narrative review of the determination of muscle mass in the past and future.Results: The material by THEILE, published by HIS in Acta Leopoldina in 1884 , provided the first data on muscle mass and its sub-masses in real humans.It was used in the classification of occupational physiological continuous performance limits for dynamic work by Frauendorf in Berlin , . Today, a variety of direct (e.g., MRI) and indirect (e.g., impedance measurements on body scales) methods are available. Muscle mass is increasingly of interest in the detection of sarcopenia .Discussion and Conclusion: The determination of muscle mass is not only of historical importance for occupational medicine/physiology. The prevention of sarcopenia in an aging society provides new inspiration for muscle mass measurements in occupational health prevention for older workers.
