Table 1. Mean HR (beats per min) and %HRR for an 8-week Phase III circuit-based CR programme.

	Mean HR during CVE	Mean HR during AR	Mean %HRR during CVE	Mean %HRR during AR
Mean	90.6	87.0	37.1	31.5
Median	88.0	84.0	37.0	34.0
SD	12.3	13.2	10.1	12.6
Minimum	74.0	67.0	17.0	10.0
Maximum	117.0	113.0	62.0	53.0

HR = heart rate (bpm); CVE = cardiovascular exercise; AR = active recovery; %HRR = % heart rate reserve; SD = standard deviation
