Question

Above 1,000 meters, every additional 1,000 meters elevation gain results in a __% reduction in Vo2Max.

a) 5%
b) 10%
c) 15%
d) 20%

Answer 1

For every 1,000 meters elevation gain above 1,000 meters, there is a 10% reduction in Vo2Max. This affects physical performance due to the decreased oxygen availability at high altitudes.

Step-by-step explanation:

The question seeks to determine the percentage reduction in Vo2Max (maximal oxygen uptake) at elevations above 1,000 meters. For every additional 1,000 meters elevation gain, studies indicate that there is approximately a 10% reduction in Vo2Max. This reduction can significantly impact an individual's physical performance as the body requires oxygen for the production of energy during exercise.

Whether engaging in climbing or any physical activity at high altitude, the body is challenged due to the lower atmospheric pressure and decreased oxygen availability. This is why mountain climbers often carry bottled oxygen to compensate for the lower oxygen levels available from the air.
