I'll give you the basics of it:
When you exercise and you feel that burn during and after a workout, that is the muscles fibers tearing up. After your workout it is very important to eat well because the process of your muscles rebuilding takes longer that it does to tear them up. The muscles will repair and rebuild bigger than before you exercised. You could work out vigorously and not eat right and you wouldn't gain much muscle. Eating right and working out itself are equally important. A common misconception is people believe you need to spend hours a day at the gym in order to build muscle. It can be as easy as working out one area of the body (arms) once a week doing no more than 5 separate exercises. The most important thing to do while working out: doing it right (technique is everything).
Yes, pH changes can occur during strenuous exercise. As muscles work harder, they produce lactic acid, which can lead to a decrease in blood pH, resulting in a more acidic environment. This condition, known as acidosis, can impact muscle performance and fatigue. Additionally, respiratory changes during intense exercise can also influence blood pH levels.
Exercise tears the muscles (causing some pain). When the muscles heal, they become defined and (stronger due to the fact they know strenuous activity will occur).
When the diaphragm and muscles of the rib cage relax, the thoracic cavity becomes smaller. These changes occur during exhalation.

During a warm-up, the elasticity of muscles increases due to the increased blood flow and body temperature. This allows for improved flexibility, decreased risk of injury, and enhanced performance during physical activity.
During the Alarm Stage of the body's stress response, several physical changes occur. The body releases adrenaline and cortisol, leading to increased heart rate and blood pressure to prepare for a fight-or-flight response. Additionally, breathing rate increases to supply more oxygen to muscles, and blood flow is diverted from non-essential functions to vital organs and muscles. These changes prime the body to react quickly to perceived threats.
If you are ill for a long time, your muscles can become weak and atrophy can occur.
so that ur muscles,bones are ready for the next activities u'll performing and no injurieswill occur.................
Chronic adaptations changes that occur as a result of repeated regular exercise and activity
exercising injuries can occur when you dont do things right. It means that if you dont stretch befaore any games you can pull a musle. Injuries can occur if you put to much presure on one leg and to much exercise.
As people age, degenerative changes in the lens's proteins occur.
