I am not sure because there may be more context, but here is what I am guessing the answer is.

As Bryson pedaled uphill both his heartbeat and breathing rate increased. His breathing rate increases to provide the body (more specifically, exercising muscles) with oxygen at a higher rate and his heart rate increases to deliver the oxygen (and glucose) to the respiring muscles more efficiently.
