Question
The reduced lactate response to exercise (lactate paradox) following acclimatized exposure to altitude is theorized to be due to which of the following? increased mitochondria in the exercising muscle. lower plasma epinephrine levels. improved oxygen delivery at the lungs. improved oxidative capacity of the muscle.
Solution
The reduced lactate response to exercise (lactate paradox) following acclimatized exposure to altitude is theorized to be due to the improved oxidative capacity of the muscle.
Here's a step-by-step explanation:
-
When you exercise at high altitudes, your body has to work harder to get the oxygen it needs, so it starts to use more glucose and less oxygen to produce energy, a process called anaerobic metabolism.
-
This process produces lactate, a substance that can cause muscle fatigue.
-
However, after spending some time at high altitudes (acclimatization), the body starts to adapt. One of these adaptations is an improvement in the muscle's ability to use oxygen to produce energy, a process called oxidative metabolism.
-
This improved oxidative capacity of the muscle means that the body can go back to using more oxygen and less glucose to produce energy, even at high altitudes.
-
As a result, less lactate is produced during exercise, leading to the so-called "lactate paradox".
So, the reduced lactate response to exercise following acclimatized exposure to altitude is theorized to be due to the improved oxidative capacity of the muscle.
