Before the exercise the breathing decreased when I was counting how many breaths I can take in a minute. These include decreased resting heart rate, improved ability to draw in deeper breaths, reduced resting blood pressure, increased calories burned to aid weight loss and reduced risk of heart disease. The rate is dependent on the tidal volume, and the value is about 6000 ml per minute. A persons stroke volume will also increase as an increase in blood plasma and blood volume occur and reduced heart rate which increases the diastolic filling time. Expiratory reserve volume decreased with exercise because greater respiratory effort forced more air out of the lungs with each exhalation.
