Performance anxiety in sports, sometimes referred to as "choking," is described as a decrease in athletic performance due to too much-perceived stress.
Explanation:
To overcome performance anxiety, a sports psychologist, coach, and trainer may try to help the athlete understand why those thoughts and feelings develop and then try to change or modify that process with limited amounts of success.
A patient has severe pneumonia, which has thickened the respiratory membrane. Despite oxygen therapy, he still has rapid breathing and feels he is not getting enough air. This is because your blood pH has increased and stimulated an increase in your respiratory rate.
- c. his blood pH increased and stimulated an increase in his respiratory rate.
<h3>How does respiratory rate affect pH?</h3>
When it is respiratory, it occurs due to an increase in the amount of volatile acids in the body, which lead to an increase in pCO2. When it is metabolic, it occurs due to the accumulation of non-volatile acids, which lead to the loss (excessive consumption) of bases, mainly bicarbonate, causing a drop in pH.
With this information, we can conclude that The respiratory system is the main controller of blood pH levels. The increase in the concentration of carbon dioxide in the blood causes an increase in H+ ions and, consequently, in acidity. Likewise, the decrease in carbon dioxide levels leads to an increase in blood alkalinity.
