Abstract
Background: Ageing is associated with changes of physical and physiological parameters, but there is evidence that regular physical activity could minimize these e ects. Additionally, the older population presents a great risk of suboptimal nutrition. Therefore, the purpose of this study was to review the evidence of nutritional strategies and endurance exercises in the older population. Methods: A systematic review was performed based on the preferred reporting items for systematic reviews and meta-analysis (PRISMA) statement. The search was carried out in three di erent databases: PubMed, Web of Science, and SPORTDiscus. Results: Eight studies were included in the present review. The use of ca eine and beta-alanine supplementation with proteins have been found to be bene cial in both sexes. In older women, a balanced diet, an increase in protein, supplementation with beta hydroxy methyl butyrate, and supplementation with sodium bicarbonate have been favorable. However, no bene t has been seen in older men with sodium bicarbonate or ubiquinone supplementation. Nevertheless, the use of supplements should be prescribed according to individual characteristics and physical activity. Conclusions: Ca eine and high protein supplement with beta-alanine may provide positive e ects in the older population. In addition, in older women, bicarbonate supplementation and beta-hydroxyethyl butyrate (HMB), lysine, and arginine supplementation have shown positive e ects on exercise performance.
