In high-intensity running, the heart needs to work quickly to meet the metabolic needs of the body’s movement.
High heart rate can cause the heart to be in a long-term overloaded state, which can easily lead to risks such as myocardial ischemia and arrhythmia.
For runners who are elderly or have a history of cardiovascular disease, uncontrolled heart rate is particularly dangerous and may trigger cardiovascular and cerebrovascular diseases.
Therefore, scientifically controlling heart rate during long-distance running can greatly reduce the burden on the heart and ensure exercise safety.
