Effects of exercise on mitochondrial oxygen uptake and respiratory enzyme activity in skeletal muscle. In pulmonary hypertension (PH), right ventricular function is clearly an important determinant of survival. With muscular hypertrophy training we will see greater peaks in breathing rates at the end of each set than we would for strength training as lactate starts to accumulate requiring oxygen to help metabolise it.

In contrast when you finish exercising your respiratory rate and tidal volume will decrease and gradually return to baseline. The increase in the respiratory rate and tidal volume in response to exercise leads to an increase in the pulmonary ventilation and thus greater delivery of oxygen to the alveoli to meet the increased demand of the exercising muscles. 2435 53 In our physiology course exercise physiology is used as a tool to review and integrate cardiovascular and respiratory physiology.
