Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is different about training at altitude and sea level that causes adaptation to occur?
A
The amount of food to eat
B
The partial pressure of O2
C
The partial pressure of CO2
D
The partial pressure of nitrogen
Explanation: 

Detailed explanation-1: -The bottom line is that altitude training is necessary for athletes who hope to compete optimally at altitude. However, there’s absolutely no scientific evidence to support the idea that altitude training is superior to sea-level training for sea-level competitions.

Detailed explanation-2: -These adaptations include increase in hemoglobin concentration, ventilation, capillary density and tissue myoglobin concentration. However, a negative effect in strength and power is related to a decrease in muscle fiber size and body mass due to the decrease in the training intensity.

Detailed explanation-3: -In high-altitude environments, you draw in less oxygen per breath than you would at lower altitudes. That means each breath will deliver less oxygen to your muscles.

Detailed explanation-4: -Maximal oxygen uptake (VO2max) measures the body’s ability to take in, transport, and utilize oxygen. As you go up in altitude, the VO2max decreases. This happens because of a decline in the barometric pressure and the partial pressure of oxygen at that altitude.
