lactic acid
After jogging, metabolic products such as lactic acid and microtears in muscle fibers can contribute to soreness and feelings of muscle weakness. Lactic acid accumulates during intense exercise when oxygen levels are low, leading to temporary muscle fatigue. Additionally, the microtears in muscle tissue from exertion trigger inflammation and a repair response, which can also manifest as soreness. This combination results in delayed onset muscle soreness (DOMS) that typically peaks 24 to 48 hours post-exercise.
Excessive vomiting can lead to loss of hydrochloric acid (HCl) from the stomach, which can disrupt the pH balance in the body. This can result in metabolic alkalosis, a condition characterized by elevated blood pH levels. Metabolic alkalosis can cause symptoms such as muscle weakness, tremors, and confusion.
When a muscle is pushed to far with exertion, small tears can occur in the muscle tissue. The pain associated with this damage when the muscle is used is called a pulled muscle.
The ending product of anaerobic respiration in muscle cells is lactic acid.

Muscle proteins are used to stimulate the growth of an exerted muscle. Even when the muscle isn't exerted it needs protein to repair and recover from the exertion previous but without exertion the muscle can no longer grow and will deplete This also applies when exerting a muscle with no protein intake (or very little). The muscle can no longer grow because the muscle has used all the stored muscle proteins for previous growth, as above once the original proteins are gone they must be replaced for extra or maintained mass.
Occurs when acetylcholine (ACh) accumulates in the neuromuscular junction. It is called a tetanic contraction.
Increasing the amount of muscle you have will raise your metabolic rate. For example, if you add ten pounds of muscle in the next year through proper strength training your body will consume an additional 350 to 500 calories daily. Muscle is your metabolic furnace that burns additional calories 24 hours a day (not just during and immediately after exercise).
