Influence of nutritional intervention combined with vitamin D on the development of sarcopenia.

Abstract

The aim of the review article was to analyze studies dealing with the implementation of nutritional intervention with vitamin D content and nutritional intervention including vitamin D in combination with resistance exercise. All these interventions are being investigated in patients with and without sarcopenia. PubMed, CINAHL and MEDLINE databases were used to search for studies. Studies from 2017-2022, in Czech and English, were searched for. All studies had to be freely accessible in fulltext and had to focus on patients older than 65 years. Only meta-analyses and randomized controlled trials (RCTs) were included in the review. A total of 5 RCTs were included in the review. These can be thematically divided into studies devoted to nutritional intervention (1) and studies devoted to nutritional intervention in combination with resistance exercise (4), where the results were most reliable. It can be concluded that the administration of nutritional intervention enriched with vitamin D, with is combined with resistance exercise, can improve vitamin D values, muscle strength and physical fitness in seniors over 65 years of age.
