Female Recreational Exercisers at Risk for Low Energy Availability

International Journal of Sport Nutrition and Exercise Metabolism, 2016
Low energy availability (LEA) describes the disruption in normal physiological function existent when insufficient energy intake is combined with exercise. To conserve energy a range of endocrine adaptations occur, impairing health and athletic performance.

Muscle Glycogen Content during Endurance Training under Low Energy Availability

Medicine & Science in Sports & Exercise, 2019
ABSTRACT Purpose The present study investigated the effects of three consecutive days of endurance training under conditions of low energy availability (LEA) on the muscle glycogen content, muscle damage markers, endocrine regulation, and endurance capacity in male runners. Methods

The Utility of the Low Energy Availability in Females Questionnaire to Detect Markers Consistent With Low Energy Availability-Related Conditions in a Mixed-Sport Cohort

International Journal of Sport Nutrition and Exercise Metabolism, 2021
The Low Energy Availability in Females Questionnaire (LEAF-Q) was validated to identify risk of the female athlete triad (triad) in female endurance athletes. This study explored the ability of the LEAF-Q to detect conditions related to low energy availability (LEA) in a mixed sport cohort of female athletes.

Prevalence of Low Energy Availability in Female Collegiate Athletes

Journal of the Academy of Nutrition and Dietetics, 2014
Participants will be able to classify female athletes at risk for low energy availability. Not consuming adequate calories to support energy expenditure is a common problem among female athletes that negatively impacts both performance and health.

Low Energy Availability, Plasma Lipids, and Hormonal Profiles of Recreational Athletes

Journal of Strength and Conditioning Research, 2018
AbstractBlack, K, Slater, J, Brown, RC, and Cooke, R. Low energy availability, plasma lipids, and hormonal profiles of recreational athletes.J Strength Cond Res32(10): 2816–2824, 2018—It has been postulated that low energy availability (LEA) impacts bone health, hormonal concentrations, and cardiovascular function. This study describes the lipid levels,

Low Energy Availability in Exercising Women: Historical Perspectives and Future Directions

Sports Medicine, 2016
Research on the health of female athletes has developed substantially over the past 50 years. This review aims to provide an overview of this research and identify directions for future work. While early cross-sectional studies focused primarily on menstruation, research has progressed to now encompass hormonal changes, bone health and lipid profiles ...

Low Energy Availability in the Marathon and Other Endurance Sports

Sports Medicine, 2007
Energy availability is the amount of dietary energy remaining after exercise training for all other metabolic processes. Excessively low energy availability impairs reproductive and skeletal health, although genetics and age may alter an individual's initial conditions and sensitivity when low energy availability is imposed.

Prevalence of Indicators of Low Energy Availability in Elite Female Sprinters

International Journal of Sport Nutrition and Exercise Metabolism, 2018
Low energy availability (LEA), and subsequent relative energy deficiency in sport, has been observed in endurance, aesthetic, and team sport athletes, with limited data on prevalence in athletes in short-burst activities such as sprinting. We examined prevalence of signs and symptoms of LEA in elite female sprinters at the start of the training season (

Commonly Used Indicators of Low Energy Availability Risk Fail to Identify Female Amateur Soccer Players With Measured Low Energy Availability During Preseason

International Journal of Sport Nutrition and Exercise Metabolism
This study aimed to determine energy availability (EA) and within-day energy balance (WDEB) in female soccer players during preseason and also explored eating disorder risk and athlete food choice. We hypothesized commonly used indicators of low energy availability (LEA) risk would correlate with measured EA and WDEB variables, and that food choice ...

Low Energy Availability, Carbohydrate Intake, and Relative Energy Deficiency in Sport: The Low Triiodothyronine Hypothesis

International Journal of Sports Physiology and Performance
Background: Recent research findings suggest that a daily diet containing low carbohydrate (LCHO) consumption coupled with low energy availability (LEA, specifically what is termed problematic LEA [P-LEA]) exacerbates the risk of developing relative energy deficiency ...
