dc.description.abstractPotassium is an alkali metal and the most abundant cation in the human body, measurable in serum, plasma, whole blood, and urine. The release of potassium from muscles into the bloodstream during intense exercise is related to the intensity of physical activity. Therefore, changes in serum potassium levels in individuals who regularly engage in sports can have significant consequences for the performance and health of athletes. Aims: To assess the impact of training on serum potassium levels in athletes by means of a broad systematic review. Following the PRISMA 2020 guidelines, a comprehensive search was conducted in electronic databases such as PubMed, Scopus, and Web of Science between April 21 and June 15, 2022. The methodological quality of the included studies was evaluated using the Effective Public Health Practice Project tool. A total of 12 primary research articles published in Portuguese, English, and Spanish were included. The study population consisted of athletes who were not taking potassium supplements. Criteria for eligibility, data sources, search strategies, study selection, and methods of analysis were meticulously followed to ensure a rigorous systematic review. Twelve studies (228 athletes, most of them football players) published between 2012 and 2020, mostly by Asia (n =6 studies; 50.0 %) and Europe (n =5; 33.4 %), and designed as longitudinal observational studies were synthesized. Out of the 12 included studies, 7 demonstrated an increase in potassium levels during exercise and a subsequent decrease after exercise. However, no definitive conclusions could be drawn, highlighting the need for further detailed studies to better understand the relationship between different sports and potassium level variations. Future studies are necessary to understand the effects of changes in potassium levels on the cardiac muscle due to the spurious correlation between potassium and cardiac arrest. This will help to establish more precise associations and implications for athlete health and performance.eng
