Answer:
Breathing much faster.
Step-by-step explanation:
Cardiovascular exercises are high intensity exercises that increase heart rate and metabolism and, when well executed, spend 400 to 600 calories per hour. A characteristic of this type of exercise is to make the individual breathe faster as a result of the effort made.
Cardiovascular exercises such as running, rowing or swimming are characterized by being performed in a short time, under maximum effort. These are intense activities that stimulate the cardiovascular, respiratory, muscular and nervous systems, and raise the maximum heart rate above 85%.
