Explanation:
Detailed explanation-1: -When you exercise, your body releases chemicals such as dopamine (pronounced doh-pa-meen) and endorphins (en-door-fins) in your brain that make you feel happy. Not only is your brain dumping out feel-good chemicals, but exercise also helps your brain get rid of chemicals that make you feel stressed and anxious.
Detailed explanation-2: -Cardiac output during exercise increases greatly owing to the relatively high heart rates that are achieved during exercise. Heart rate increases proportionately with workload until heart rates close to maximal are attained.
