A mixed-method approach to low energy availability in elite track cyclists
Relative Energy Deficiency in Sport (RED-S) is a complex condition that has a range of health consequences involving, but not limited to, metabolic, immune, and reproductive function, and psychological health. Low energy availability (LEA) is the underlying cause of RED-S. LEA can be defined as …

Reproductive patterns of deep-sea invertebrates related to phylogeny and energy availability
… output of an individual is strongly affected by energy availability in the environment. The number of eggs (quantified as fecundity) or their quality (size and contents of the eggs) vary with food quantity and quality and with habitat stability. Fecundity is related directly to other main life …

Risk of Low Energy Availability in Elite Male Athletes with Spinal Cord Injury
… has suggested that males are at risk for low energy availability (LEA); however, there is a paucity of research pertaining to prevalence amongst male athletes with an impairment. Therefore, the purpose of this study was to examine the risk of LEA and prevalence of symptoms related to Relative …

The Effects of Low Energy Availability and High-Impact Exercise on Bone and Body Composition
Low energy availability (LEA) has been identified as the underlying etiology of the Female Athlete Triad and Relative Energy Deficiency in Sport (REDs) syndrome. The term energy availability (EA) describes the amount of dietary energy intake (EI) that is remaining to support physiological function …

The Effects of Macronutrient and Energy Availability on Metabolic Responses to Exercise: Implications for Training Adaptation
… typically advise high carbohydrate (CHO) availability before, during, and after exercise in order to support high training intensities and volumes. However, accumulating data now suggest that restricting CHO and/or energy availability around training may augment the exercise-induced cell …

UTILIZING THE LEAF-QUESTIONNAIRE TO DETERMINE THE RISK OF LOW ENERGY AVAILABILITY IN COLLEGE FEMALE WRESTLERS
… overtraining. This can ultimately lead to Low Energy Availability (LEA). <strong>Purpose:</strong> The primary purpose of this study was to examine the number of National Collegiate Athletic Association Division II female college wrestlers at risk for LEA during in-season training. The …

Characterizing the Use of Continuous Glucose Monitors During Experimentally-Induced Short-Term Low Energy Availability in Female Endurance Runners
Female endurance runners are at high risk for low energy availability (LEA). Preliminary evidence suggests that fasting blood glucose (BG) concentration decreases in response to short-term energy deficiency (low energy availability). BG monitoring tools, such as continuous glucose monitors (CGM), …

The utilization and loss of available energy in aerospace systems
… methodology for the control volume-based energy availability methodology for aerospace vehicles are developed; applications are made to jet-propelled and rocket-propelled vehicles as well as to stand-alone engine systems. Energy availability utilization characteristics of a modeled …

Prevalence of Low-Energy Availabilty Amongst Female Paralympic Athletes
<p>The prevalence of low-energy availability (LEA) in able-bodied female athletes has been extensively examined; however, research has yet to examine LEA in Paralympic athletes. Therefore, the purpose of this study was to examine the risk of LEA and related symptoms including menstrual health, …

The potential treatments of osteoporosis and hormone dysregulation caused by female athlete triad syndrome
… disorder that presents as a dysregulation of energy availability, menstrual functioning, and bone health. This condition impacts a growing number of female athletes. The triad of physiological and endocrine disruption can develop into conditions of low energy availability, functional …

A bioenergetic simulation model of orchard populations of the pine vole (Microtus pinetorum)
… functions of bioenerqetic status. Forage gross energy availability, digestibility, palatability, and preference were functions of Julian day. Daily energy budget (DEB) was a function of age, reproductive status, body weight, ambient temperature, and daily activity level. Energy acquisition was …

Energy harvesting-aware design of wireless networks
Recent advances in low-power electronics and energy-harvesting (EH) technologies enable the design of self-sustained devices that collect part, or all, of the needed energy from the environment. Several systems can take advantage of EH, ranging from portable devices to wireless sensor networks …

Dynamic energy budgets and bioaccumulation : a model for marine mammals and marine mammal populations
Energy intake of individuals affects growth of organisms and, therefore, populations. Persistent lipophilic toxicants acquired with the energy can bioaccumulate and harm individuals. Marine mammals are particularly vulnerable because of their large energy requirements, and transfer of energy and …

Distinct roles for energy storage and transmission infrastructure in a renewables-based electric power system
… In this study, we analyze the roles of energy storage systems (ESS) and transmission infrastructure in the cost-optimal deployment of a renewable electricity grid in the United States. We find that storage and transmission serve distinctly different functions: transmission is useful for …
