Research of Sarcopenia in Patients After Bariatric-metabolic Surgery - the Effect of Programmed Aerobic and Power Exercising on the Functionality, Volume and Morphology of Muscle Tissue

The investigators' study published in 2020 (Pekar, M. et al.: The risk of sarcopenia 24 months after bariatric surgery - assessment by dual energy X-ray absorptiometry (DEXA): a prospective study; Videosurgery Miniinv 2020; https://doi.org/10.5114/wiitm.2020.93463) shows that patients are at risk of sar-copenia after bariatric-metabolic (BM) surgery. BM surgery leads to significant changes in body composition. Significant fat loss is followed by unwanted muscle loss. The study shows that the lack of physical activity is typical for these patients. To the algorithm of postoperative care the investigators plan to include controlled exercise programs for these patients. The investigators do not know what the complexity and time required to keep patients in good condition and reduce the risk of sarcopenia is. The investigators want to find the adequate amount of physical activity while maintaining long-term compliance of these patients.
