Study Notes on RED-S and Female Athlete Triad

Purpose: Understand RED-S and its consequences in the context of body image and eating disorders.
Audience: Relevant for individuals entering medical or healthcare fields, especially those working with young athletes.
Importance of topic: Discusses recognition of warning signs, identifying risk factors, and differentiating between RED-S and the female athlete triad.

Background: Mary Kayne, an adolescent female athlete, was regarded as the fastest woman in the world.
Coaching Context:
- Joined the Nike Oregon team coached by Alberto Salazar.
- Experienced pressure from an all-male coaching team to lose weight without scientific justification.
Consequences:
- Developed amenorrhea, loss of menstrual cycle for over three years.
- Suffered multiple stress fractures.
- Significant decline in performance, now not running competitively.

Full Form: Relative Energy Deficiency in Sport.
Description: Physiological impairments negatively impacting performance due to low energy availability.
Not restricted to eating disorders: Can occur in individuals with normal eating patterns that are insufficient for their activity level.

Effects on athletic performance:
- Decreased endurance performance.
- Increased injury risk.
- Decreased training response.
Major Consequences:
- Reproductive Health:
- Women: Disrupted menstruation may lead to infertility.
- Men: Low libido.
- Bone Health:
- Increased risk for stress fractures due to decreased bone mineral density.
- Potential for early onset osteoporosis in young athletes.
- Cardiovascular Health:
- Very low heart rate leading to dizziness.
- Potential long-term damage to the heart muscle.
- Psychological Health:
- Higher rates of depression and anxiety among individuals.
- Immunity:
- Decreased immunity leading to higher infection rates, impacting performance and quality of life.
- Metabolism:
- Body slows metabolism to protect itself, further aggravating low energy availability.

Common Indicators:
- Stress fractures.
- Disrupted menstrual function.
- Rapid weight loss.
- Performance issues after dietary or training changes.
Other signs:
- Mood changes (irritability, depression).
- Hyperfixation on training or diet.
- Decreased team contribution and experience.

Sports Characteristics:
- Sports emphasizing body aesthetics (e.g., gymnastics, figure skating).
- Endurance sports (e.g., marathon running, ultra-marathons) with high training demands.
- Sports with frequent weigh-ins (e.g., women's gymnastics).
Team Culture:
- Culture emphasizing winning at all costs.
- Body shaming culture among athletes.
- Negative peer pressure and emphasis on appearance can increase risk.
Personality Traits:
- Perfectionism.
- Low confrontation—athletes may acknowledge unhealthy practices but avoid confrontation to please coaches and others.

Female Athlete Triad Components:
- Disordered eating behaviors.
- Amenorrhea.
- Issues with bone health (usually presenting as stress fractures).
Strengths of RED-S:
- Broader application beyond eating disorders: Addresses cardiovascular, metabolic, growth, developmental, immune, and endocrine impacts.
- Recognizes that individuals may not have disordered eating but can still experience RED-S due to energy mismatches.
- Inclusivity: Encompasses non-female identified athletes and reflects energy availability effects across all genders.
- Emphasizes holistic view of health in athletic performance rather than just menstrual function and bone health, capturing a wider range of affected individuals.
