Cardiovascular Outcomes and Relative Energy Deficiency in Division I HBCU Athletes: CORE-DI Study
North Carolina Agriculture & Technical State University
Summary
Low energy availability (LEA) occurs when the body does not get enough calories to support both daily life and exercise. This can happen when athletes train hard but do not eat enough to match their energy needs. In both 2012 and 2023, the International Olympic Committee on Sports Nutrition recognized LEA as an important factor that can increase the risk of cardiometabolic disease (CMD), which includes conditions like high blood pressure, diabetes, and heart disease. LEA can affect many systems in the body. It may disrupt hormones (such as menstrual cycles), cause changes in blood sugar and cholesterol levels, weaken bones, impair digestion, and negatively impact mental health. Over time, these changes may be linked to chronic inflammation, which plays a key role in the development of disease. Maintaining proper energy balance can be especially challenging for athletes because they often train at levels well above general health recommendations. As a result, even highly fit athletes may unintentionally remain in a calorie deficit. Our recent pilot research found a significant relationship between LEA and high blood pressure in Black Division I collegiate athletes. This is important because this group has historically been understudied and may face a higher risk of serious heart-related events, including sudden cardiac death. Despite assumptions that collegiate athletes are uniformly healthy, there is a need to better understand hidden health risks in this population. Our research aims to improve how we identify and monitor early signs of cardiometabolic disease by examining markers such as inflammation, blood sugar, and cholesterol levels. These insights will help healthcare providers, athletes, and families make more informed decisions about nutrition, training, and long-term health. Ultimately, this work seeks to develop practical, evidence-based strategies to protect athlete health and reduce the risk of serious cardiovascular outcomes.
Description
SPECIFIC AIMS: The International Olympic Committee on Sports Nutrition (IOCSN) recognized low energy availability (LEA), defined as inadequate calorie intake relative to energy expenditure. LEA may be particularly important cardiovascular disease (CVD) risk among minority athlete populations, especially those exposed to poor Social Determinants of Health (SDOH). This includes Black NCAA Division I collegiate athletes (BD1As), who make up 21% of the Division I population and have a 5x higher risk of sudden cardiac death compared to white athletes. Many of the SDOH indicators are alleviated as a…
