HRmax, estimated maximum heart rate from baseline maximal exercise testing data

^aWeek 1 set up / facilitation period excluded

*Significant difference in maximum recorded HR across the program (weeks 2–4 vs. 5–8, p = 0.08; weeks 2–4 vs. 9–12, p = 0.002; weeks 5–8 vs. 9–12, p = 0.02)

**Significant difference in % HRmax across the program, (weeks 2–4 vs. 5–8, p = 0.002, weeks 2–4 vs. 9–12, p = 0.29; weeks 5–8 vs. 9–12, p = 0.23)
