Low Energy Availability and Cardiovascular Disease

Detailed Summary

Low energy availability (LEA) signifies a condition where the body lacks sufficient energy to support essential physiological functions crucial for maintaining optimal health (1). This energy insufficiency can be exacerbated by the demands of sports and exercise, resulting in negative impacts on various physiological, psychological, and sports performance (11, 8, 2). While LEA is commonly associated with cardiovascular abnormalities, such as early atherosclerosis, endothelial dysfunction, and lower blood pressure, the existing body of research faces limitations, including small sample sizes and primarily exploratory approaches (2). Additionally, despite a growing body of evidence suggesting a strong link between DNA methylation (an epigenetic modification influencing gene expression by tagging specific parts of the DNA code) and cardiovascular disease (9, 6), there has been no prior investigation exploring the interplay between DNA methylation, cardiovascular disease, and LEA. To better understand LEA and its effects on cardiovascular health, it is imperative to address these limitations through further research. Utilising more comprehensive markers of cardiovascular disease and expanding the scope of investigations will contribute to a great understanding of LEA and its implications on cardiovascular health (10).
