Researchers are investigating the effects of low energy availability (LEA) on cardiovascular health in trained to elite female athletes aged 18 to 35. LEA occurs when the body does not have enough energy to support essential functions, which can negatively impact physical and psychological health as well as sports performance. This study aims to address current research limitations by examining the relationship between LEA, cardiovascular disease markers, and DNA methylation, an epigenetic factor linked to heart disease. The study involves 126 female athletes from local sports clubs who will visit a laboratory once for data collection. During this visit, researchers will gather demographic, anthropometric, and genetic data, perform detailed blood tests assessing hormones and cardiovascular markers, and conduct heart and blood vessel health assessments using methods like pulse wave velocity and electrocardiograms. Participants will also complete nutritional and physical activity assessments, eating behavior and mood questionnaires, and energy availability evaluations. Prior to testing, participants will monitor their menstrual cycles for two months using tracking apps and ovulation tests to ensure hormonal measurements occur during a consistent menstrual phase. Participants will contribute data on cardiovascular risk factors and DNA methylation patterns, with analyses incorporating machine learning to identify novel patterns in lipid and metabolite profiles. The primary outcome is to measure cardiovascular risk factors associated with LEA, while secondary outcomes include examining DNA methylation characteristics. The study includes careful scheduling and monitoring to minimize hormonal variability, and participation involves a single laboratory visit supplemented by home-based menstrual monitoring over two months.
