Relative Energy Deficiency in Sport (RED-S): The Hidden Epidemic in Jumpers
How the pressure to stay 'light' for vertical and horizontal jumps triggers severe metabolic and hormonal collapse.
Why this matters
Because the High Jump, Pole Vault, and Triple Jump heavily penalize excess body weight, athletes inherently face immense psychological pressure to stay as small and light as possible.

RED-S, formerly known as the Female Athlete Triad (though it heavily affects male jumpers as well), occurs when an athlete's caloric intake is insufficient to support both their basal metabolic rate (basic living functions) and their heavy training load. The body essentially enters starvation mode.
The Physiological Shutdown
When a jumper lives in chronic Low Energy Availability (LEA), the brain begins shutting down "non-essential" systems to keep the heart beating and the lungs breathing.
The Affected System
The Clinical Pathology
The On-Track Consequence
**Endocrine (Hormones)**
Menstrual dysfunction in females. Testosterone drops in males.
Absolute inability to maintain or build explosive fast-twitch muscle fiber.
**Skeletal (Bones)**
The body halts bone turnover and calcium deposition to save energy (Osteopenia).
Inevitable, catastrophic stress fractures in the takeoff tibia, fibula, or navicular.
**Neurological (Brain)**
Central nervous system starvation and neurotransmitter depletion.
Clinical depression, severe irritability, and a total loss of competitive drive.
