Final answer:
Overactivity or tightness of the chest muscles can result in angina, asthma symptoms, and forced breathing during exercise.
Step-by-step explanation:
One common condition is angina, which is chest pain or pressure caused by inadequate blood flow to the heart muscle cells, leading to oxygen deprivation. This can occur due to atherosclerosis, the buildup of plaque in the coronary arteries.
In addition, tightness of the chest muscles can contribute to symptoms of asthma, such as difficulty breathing, coughing, and chest tightness. In asthma, the air passages of the lungs become narrow, often with excessive mucus production, leading to respiratory difficulties.
Furthermore, overactivity of the chest muscles can be observed during forced breathing or hyperpnea, which occurs during exercise or actions that require active manipulation of breathing. In hyperpnea, accessory muscles of the neck and abdomen contract along with the diaphragm and intercostal muscles to increase lung volume and facilitate breathing. So therefore the overactivity or tightness of the chest muscles can result in various symptoms and conditions.
