Summary
Relative Energy Deficiency in Sport (RED-S) is a condition where low energy availability impairs multiple bodily functions, expanding on the Female Athlete Triad. Understanding RED-S is crucial for athletes
Area of Science:
- Sports Medicine
- Exercise Physiology
- Endocrinology
Background:
- Relative Energy Deficiency in Sport (RED-S) is a condition impacting athletes due to energy imbalance.
- It expands upon the previously recognized Female Athlete Triad diagnosis.
- Low energy availability is identified as the primary cause of RED-S's medical complications.
Purpose of the Study:
- To review the history and evolution of the RED-S diagnosis and terminology.
- To assess the practical application and comparability of energy availability equations.
- To provide guidance on identifying and managing RED-S in athletes.
Main Methods:
- Literature review of RED-S history, definitions, and consequences.
- Analysis of the energy availability equation and its practical challenges.
- Examination of health outcomes, particularly hypoestrogenemia and menstrual dysfunction.
Main Results:
- RED-S encompasses a wide range of health consequences beyond menstrual dysfunction.
- Challenges exist in consistently applying and comparing energy availability calculations.
- Identification and management strategies for RED-S are discussed.
Conclusions:
- RED-S is a complex condition requiring a comprehensive understanding of energy availability.
- Early recognition and intervention are vital for athlete health.
- Coaches, athletic trainers, and families play a key role in supporting athletes with RED-S.

01:12Relative Risk
315
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

01:24Muscle Recovery and Fatigue
2.4K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

01:27Redox Reactions
102
Redox reactions are vital biochemical processes that underpin energy metabolism in cells. These reactions involve the transfer of electrons between molecules, occurring in tandem as oxidation and reduction. Oxidation refers to the loss of electrons, while reduction denotes their gain. This coupling ensures the seamless flow of electrons through metabolic pathways. For example, in bacterial metabolism, glucose undergoes oxidation to carbon dioxide, while oxygen is simultaneously reduced to...

183
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

01:12Coefficient of Correlation
6.3K
The correlation coefficient, r, developed by Karl Pearson in the early 1900s, is numerical and provides a measure of strength and direction of the linear association between the independent variable x and the dependent variable y.
If you suspect a linear relationship between x and y, then r can measure how strong the linear relationship is.
What the VALUE of r tells us:
The value of r is always between –1 and +1: –1 ≤ r ≤ 1.
The size of the correlation r indicates the...
