👩‍🔬 science lesson incoming!!! Why do endurance athletes love (hate) training at high altitudes? 🏔️ Fun fact: the concentration of oxygen in the air is actually the same wherever you go. It’s all about the PRESSURE! The higher you go, the less atmospheric pressure there is pushing the air down on you and into your lungs.🫁 When you ask your body to do WORK under these conditions it adapts by cueing the kidneys to create EPO which is a hormone that then tells BONE MARROW to produce more red blood cells (which carry oxygen to your muscles). 🦴 🩸 After the body adapts, we then go down to sea level to race but now we can carry WAY more oxygen to our working muscles and we dont get fatigued as quickly. Magic!!! 🪄 ✨ Isn’t that crazy?!? Our bodies are so smart! And so adaptable!! #themoreyouknow🌈⭐️ #science #altitudetraining #womeninstem
