Introduction: Sarcopenia and osteoporosis are diseases commonly observed in older adults, which can lead to serious health issues and represent a significant economic burden on healthcare systems worldwide. The coexistence of sarcopenia and osteoporosis is described as the osteosarcopenia. Consequences for individuals suffering from both conditions include an increased risk of falls, fractures, institutionalization, and mortality. Physical activity combined with dietary supplements has a beneficial effect on sarcopenia and osteoporosis symptoms and improves the quality of life in older adults. Purpose: The aim of this thesis was to determine the effectiveness of resistance exercise in preventing and treating osteosarcopenia in older adults through a review of scientific literature. Methods: The search for scientific literature was conducted in the PubMed/Medline and BioMed Central databases using the following English keywords: "resistance training AND ((sarcopenia AND osteoporosis) OR osteosarcopenia)) AND elderly." The search covered the period from 2013 to 2023. The methodological quality of the articles was assessed using the PEDro scale. Results: Based on the inclusion criteria, three randomized controlled trials and one cross-sectional study were included in the detailed literature review. The exercise programs in the analysed studies included resistance training exclusively on machines, as well as aerobic and combined exercise. In all four analysed studies, there was a statistically significant improvement in functional parameters related to sarcopenia, osteoporosis, and osteosarcopenia. Discussion and conclusion: Through a systematic review of the literature, we found that various forms of physical exercise have positive effects on improving or maintaining symptoms in older adults with sarcopenia and osteoporosis. Resistance exercise has been shown to prevent or at least slow down the worsening of sarcopenia and osteoporosis symptoms and has beneficial effects on improving muscle mass, muscle strength, physical performance, and bone mineral density in older adults individuals. Further research on the long-term effects of resistance exercise on the symptoms of sarcopenia and osteoporosis, as well as the impact of resistance exercise on bone mineral density in male subjects, would be meaningful.
