What characterizes acute-onset muscle soreness?

Acute-onset muscle soreness is characterized by its onset during or shortly after physical activity. This type of soreness is typically temporary and is often a result of muscle fatigue or minor muscle damage that occurs during exercise. The intensity can vary based on the activity level, but it typically subsides as the body recovers. This is in contrast to chronic soreness or pain, which can develop over time and may indicate a more serious issue. Acute soreness is a common experience for athletes and individuals engaging in strenuous exercise, serving as a normal response to increased physical demands placed on the muscles.
