Why does heart rate increase prior to exercise?
The anticipatory rise is the mind’s response to the body’s need to prepare for exercise. Subconsciously, the body knows it is about to exercise and therefore the brain sends several signals in the form of neurotransmitters (e.g. noradrenaline) and hormones (e.g. adrenaline) to the heart.
