Health Consequences Of Low Energy Availability In Females And Their Underlying Physiological Mechanisms, Grace Parry
Health Consequences Of Low Energy Availability In Females And Their Underlying Physiological Mechanisms, Grace Parry
Senior Honors Theses
Low energy availability (LEA) is a state in which energy intake is insufficient to support energy expenditure while maintaining energy balance, which has been shown to result in gastrointestinal distress, immunosuppression, reduced metabolic rate, menstrual dysfunction, diminished bone health, and impaired cardiovascular function in females. Alterations to the microbiome and mucosal lining may propagate gastrointestinal complaints and compromised immune function associated with LEA. The pathophysiology of LEA is otherwise largely driven by hormonal adaptations. Diminished production of thyroid hormones is known to contribute to reduced metabolic rate. Decreases in leptin and insulin and increases in ghrelin disrupt reproductive function through …
Ideal Body Weight And Body Fat Percentage Predict Relative Energy Deficiency In Sport (Red-S) Scores In Collegiate Athletes, Emily Norman
Ideal Body Weight And Body Fat Percentage Predict Relative Energy Deficiency In Sport (Red-S) Scores In Collegiate Athletes, Emily Norman
Theses and Dissertations--Nutrition and Food Systems
Background: Low energy availability (LEA) is the underlying cause of Relative Energy Deficiency in Sport (RED-S) which negatively affects athletes' physiological function, health, and performance. RED-S results from inadequate dietary intake to support energy expenditure for daily living, growth, and optimal performance. It occurs in both male and female athletes, with or without disordered eating. However, screening and diagnosis in athletes can be difficult. Objective: This study aims to identify strong predictors of RED-S and assess its prevalence in collegiate male and female athletes. Methods: A total of 270 NCAA athlete test points from mixed sports were evaluated for RED-S …
