Sarcopenia is the progressive loss of muscle mass and strength with age, which has many negative consequences. Especially older adults admitted to the hospital are vulnerable; however, not well studied in the context of sarcopenia.

The overall objectives of this PhD project involving geriatric medical patients were to evaluate a screening tool developed to identify the risk of sarcopenia.

Furthermore, to investigate the effect of a long-term treatment strategy to counteract sarcopenia by combining protein supplementation with resistance training (RT) compared to RT alone.

Finally, the agreement in body composition measurements between two specific devices (bio-impedance analysis and dual-energy X-ray absorptiometry) was investigated.
