Final answer:
The factors that can decrease the rate and quality of the CRI are hyperventilation, metabolic acidosis, overfeeding leading to lipogenesis, and exercise.
Step-by-step explanation:
The factors that can decrease the rate and quality of the CRI (Cardiorespiratory Fitness Index) are hyperventilation, metabolic acidosis leading to an increase in carbon dioxide, and overfeeding leading to lipogenesis. Additionally, exercise can also decrease the CRI. Hyperventilation causes a decrease in carbon dioxide levels, which can affect the acid-base balance in the body. Metabolic acidosis leads to an increase in carbon dioxide levels, which can negatively impact the functioning of the cardiovascular and respiratory systems. Overfeeding and excessive lipogenesis can contribute to weight gain and reduce overall fitness levels. Lastly, engaging in exercise that is too intense or prolonged can lead to fatigue and decrease CRI.
