  1. aReference value is exercise ≤1 times per week. bAge divided by 10. cDiastolic BP had female n = 43, female obs = 78, male n = 78, male obs = 141. dRHR had female n = 43, female obs = 78, male n = 78, male obs = 141. eVO2max had female n = 20, female obs = 55, male n = 32, male obs = 55
  2. BP = blood pressure; RHR = resting heart rate; VO 2max  = maximal oxygen uptake
