WebDepending on how high above sea level the ground is, altitudes could be as high as 15,000 MSL (mean sea level) before a jumper is required to use supplemental oxygen. At those altitudes hemoglobin is less effective at carrying oxygen, which is why hypoxia is a risk. Web-During exercise transient time decreases: CO goes up, blood flow speeds up, so time to load and make it through the capillary shortens. This is not an issue in normal people, but in elite athletes, if it gets too fast, the hemoglobin does not get loaded up with enough oxygen since bloodflow is too fast.-Thicker the membrane, harder it is for diffusion.

The effects of high altitude on humans are mostly the consequences of reduced partial pressure of oxygen in the atmosphere. The oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around 2,100 metres (6,900 ft) above sea level, the saturation of … See more The human body can perform best at sea level, where the atmospheric pressure is 101,325 Pa or 1013.25 millibars (or 1 atm, by definition). The concentration of oxygen (O2) in sea-level air is 20.9%, so the partial pressure of … See more For athletes, high altitude produces two contradictory effects on performance. For explosive events (sprints up to 400 metres, long jump, triple jump) the reduction in atmospheric pressure means there is less resistance from the atmosphere and the athlete's … See more • Nosek, Thomas M.
