Because most systems in the body are chemically driven. Like electrolytes. These are the charged particles that must maintain an electrical balance simply by the laws of physics, sodium, potassium, chlorides, HCO3 etc.Then there is the glucose-insulin balance and the pH balance. These cannot overcompensate because once they get near normal levels the impetus to correct the imbalance is gone. Like when you run or exercise your muscles build up acids which your body compensates for by breathing deeper and faster. But once the pH gets back to near 7.40 breathing slows down and everything goes back to normal.
There are instances where the body can overcompensate as in an acute Asthma attack where the person is already breathing fast and as deep as they can but even when the airways are opened again the fear and anxiety of that breathlessness drives the respiratory rate higher and therefore overcompensates.

The Hering-Breuer reflex is a protective mechanism that prevents over-inflation of the lungs during breathing. During exercise, as the rate and depth of breathing increase, stretch receptors in the lungs send signals to the brain to regulate respiratory patterns. Although the reflex is less active during intense exercise, it helps maintain appropriate ventilation and prevents damage to lung tissue by signaling when to inhibit further inhalation. This allows for efficient gas exchange while accommodating the increased oxygen demand of the body.
respiratory system change with more exercise because it is related to our cardiovascular and respiratory system.when we do exercise our heart rate increases cardiac output increases and oxygen is more utilizing and more energy is required.These all cause effect on respiratory system
The respiratory system is unimportant during strength training and stretching. It is very important during cardiovascular exercise (cardio). Regular cardio that is neither too mild nor too strenuous can be very beneficial to your body. .
the respiratory centers
While exercise generally benefits the respiratory system, it can have negative effects in certain situations. Intense physical activity can lead to exercise-induced bronchoconstriction, causing wheezing and shortness of breath, particularly in individuals with asthma or respiratory sensitivities. Additionally, prolonged vigorous exercise may result in respiratory muscle fatigue and decreased lung function if not properly managed. Lastly, exposure to cold, dry air during outdoor exercise can irritate the airways and exacerbate respiratory issues.
When you do cardio respiratory exercises, you enable more blod flow and you exercise the heart. The breathing in respiratory exercises also cleanse the breathe and helps you have more oxygen in the body.
During exercise, blood flow increases to deliver more oxygen and nutrients to muscles and remove waste products like carbon dioxide. This helps muscles work efficiently and prevents fatigue.
Respiratory minute volume refers to the volume of breath per minute. During exercise, this amount increases up to 20 to 30 times the normal value. Exercising regularly improves lung performance and makes breathing easier.
Exercise places greater oxygen demands on the body, therefore signaling the respiratory center to increase the rate of respiration in order to increase the oxygen supply to the body's muscles and other tissues.
The term exercise physiology refers to the study of how the body responds and adapts to physical activity and exercise. It encompasses understanding how various physiological systems, such as cardiovascular, respiratory, and muscular systems, function during exercise, as well as how exercise impacts overall health and performance.
