Don't take only my word for it, but, i think it would be a chemical change because if you think about it you are inhaling oxygen and exhaling carbon dioxide. Which would make it a chemical change, but I am not 100% positive.
Breathing is a chemical process. When air is breathed in, it reacts chemically; when a person breathes out, they release more carbon dioxide than they breathed in, and less oxygen.
The fact that exercise does not directly impact breathing does not necessarily affect overall physical fitness and performance. Breathing is controlled by the respiratory system, which adapts and improves with regular exercise. While exercise may not directly change breathing patterns, it can improve cardiovascular fitness, muscle strength, and endurance, all of which contribute to overall physical fitness and performance.
