When a person runs, their heart rate increases to supply more oxygen-rich blood to the muscles, which require more energy during physical activity. This increase in heart beats is regulated by the autonomic nervous system, primarily through the release of adrenaline, which accelerates heart contractions. Additionally, the body’s demand for oxygen rises, prompting the heart to pump faster to meet this increased metabolic need. As a result, the heart rate can significantly elevate, often reaching 60-100% above resting levels during vigorous exercise.
