Complete the statements to describe and explain the patterns shown in Fig. 6.1. Once exercise has finished, it takes [BLANK] minutes for the athlete’s breathing rate to return to its resting rate. The heart rate falls by [BLANK] beats per minute between 20 and 40 minutes. The heart rate and breathing rate do not return at once to their resting rates because anaerobic respiration has taken place. Lactic acid has accumulated in [BLANK], causing an oxygen [BLANK]. The heart rate remains high so that lactic acid can be carried to the [BLANK]. The breathing rate remains high to provide [BLANK] for the [BLANK] respiration of lactic acid.
