Which stress hormone increases with excessive exercise and low intake?
Cortisol
This condition involving reduced bone strength and increased fracture risk can result from prolonged low energy availability.
Osteoporosis
What structural protein is a major component of tendons and ligaments?
Collagen
This electrolyte is critical for muscle contraction and nerve signaling.
Potassium
What vitamin is required for normal calcium absorption to support bone loading with movement?
Vitamin D
This condition happens when the body does not have enough fuel to support exercise, recovery, hormones, organs, aned other basic body functions at the same tim
Low energy availability
When the body has enough energy and fuel available, it is better able to maintain this stable internal balance during exercise and recovery.”
homeostasis
After movement, protein supports this process in the body.
Muscle repair
This electrolyte is primarily responsible for fluid balance and is lost in sweat.
Sodium
What mineral allows muscles to contract and relax by triggering muscle fiber activation?
Calcium
This recovery process is essential after movement and allows the body to repair, restore energy, and become stronger over time
Rest
What syndrome links under-fueling with impaired performance and health across multiple systems?
RED-S (Relative Energy Deficiency in Sport)
Protein works alongside this macronutrient to support recovery after exercise.
Carbohydrates
This organ plays the primary role in regulating fluid and electrolyte balance.
The kidneys
What vitamin is necessary for collagen formation, supporting tendons and ligaments during movement?
Vitamin C.
This body response can happen during recovery when your body starts healing and repairing itself, causing you to need more energy and food than expected—especially if movement is added back in.
Hypermetabolism
This hormone involved in metabolism and energy regulation may be suppressed during chronic energy deficiency.
Thyroid hormone
After activity, protein helps your body recover and supports this system that helps fight off illness.
