Low Energy Availability Followed by Optimal Energy Availability Does Not Benefit Performance in Trained Females

Medicine & Science in Sports & Exercise, 2023
ABSTRACT Purpose Short periods of reduced energy availability are commonly undertaken by athletes to decrease body mass, possibly improve the power-to-mass ratio, and enhance physical performance. Our primary aim was to investigate the impact of 10 d of low energy availability (LEA) followed by 2 d of optimal energy ...

Patterns of energy availability in free-living athletes and the physiological effects of controlled low energy availability in males [PDF]

The physiological effects of short-term low energy availability have been characterised in females; however, the responses of males are less well understood. The aim of this thesis was to examine the daily patterns of energy availability in free-living athletes and subsequently, to determine the endocrine, metabolic, and physiological effects of low ...

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 ...

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.

Contributing Factors to Low Energy Availability in Female Athletes: A Narrative Review of Energy Availability, Training Demands, Nutrition Barriers, Body Image, and Disordered Eating

Nutrients, 2022
Relative Energy Deficiency in sport is experiencing remarkable popularity of late, particularly among female athletes. This condition is underpinned by low energy availability, which is a byproduct of high energy expenditure, inadequate energy intake, or

Low Energy Availability in Athletes

Nutrition Today, 2023
Relative Energy Deficiency in Sport (REDs) is a syndrome of impaired physiological function due to low energy availability (LEA) such that there is insufficient energy intake after subtracting the cost of energy expended through exercise. There are no universal criteria to identify an athlete with REDs.

RMR Ratio as a Surrogate Marker for Low Energy Availability

Current Nutrition Reports, 2022
Low energy availability (EA) poses severe consequences to athlete performance and overall health. Suppressed resting metabolic rate (RMR) has been observed during periods of low EA. Thus, it has been suggested that the ratio of RMR measured via indirect calorimetry to predictive RMR using a standard predictive equation (RMR ratio) may be a useful ...

Energy availability in athletes

Journal of Sports Sciences, 2011
This review updates and complements the review of energy balance and body composition in the Proceedings of the 2003 IOC Consensus Conference on Sports Nutrition. It argues that the concept of energy availability is more useful than the concept of energy
