Sports + performance
Does endurance performance usually improve or decrease immediately at high altitude, or stay the same?
Decrease.
What happens to your heart rate when your body is under environmental stress like heat, cold, or altitude?
Your heart rate increases.
What condition occurs when the body does not receive enough oxygen at high altitude?
hypoxia
Name one common symptom of Acute Mountain Sickness.
Headache, nausea, dizziness, or fatigue.
What increases in the blood after spending time at high altitude?
Red blood cells.
Why do athletes sometimes train at high altitude?
To increase red blood cells and improve oxygen delivery.
Muscles contracting in cold conditions to warm the body.
What is shivering?
What happens to breathing rate when a person first arrives at high altitude?
It increases to bring more oxygen into the body.
Why are people more likely to become dehydrated at high altitude?
Increased breathing and fluid loss.
What hormone stimulates red blood cell production at altitude?
Erythropoietin (EPO).
What training strategy involves living high but training at lower altitude?
Live high, train low.
A skin injury caused by prolonged exposure to freezing temperatures.
What is frostbite?
What happens to breathing rate when a person first arrives at high altitude?
There is less oxygen available in the air, so muscles receive less oxygen for energy.
What dangerous altitude illness causes fluid buildup in the lungs?
High Altitude Pulmonary Edema (HAPE).
What blood measurement increases as red blood cells increase?
Hematocrit.
Why can sprint events sometimes benefit from high altitude?
Lower air resistance.
The process that helps cool the body during exercise in hot environments.
What is sweating?
What is the name of the illness that causes headaches, nausea, and dizziness when someone climbs to high altitude too quickly?
Acute Mountain Sickness (AMS)
What altitude illness causes swelling in the brain?
High Altitude Cerebral Edema (HACE).
A population known for natural high-altitude adaptation.
What are Sherpa people (or Tibetan populations)?
How does altitude affect VO₂ max?
VO₂ max decreases because less oxygen is available.
Why does the body increase breathing and heart rate at high altitude?
To deliver more oxygen to tissues and muscles.
What long-term adaptation helps people living at high altitude deliver more oxygen to their muscles?
Increased red blood cell and hemoglobin production.
What is the best way to prevent altitude sickness?
Gradually acclimatizing and ascending slowly.
Why do people living long-term at altitude have improved oxygen delivery?
They have more red blood cells and improved oxygen transport.
