This practical allowed for a better understanding of the changes in cardiovascular (heart rate and blood pressure) and respiratory (ventilation and oxygen consumption) during submaximal exercise, in that they all increase in response to increasing watt power during submaximal exercise. The results were as expected with no surprising outcomes.
Figure 1 showed that ventilation increased as watt power increased, going from 25 l/min at 60 watt levels to 49 l/min at 150 watt levels. Ventilation increases as a result of submaximal exercise as there is a higher demand for oxygen around the body, and therefore the lungs must work harder to meet these demands (Betts et al., 2013). This means that in order for the lungs to delivery more oxygen to the
