  Predicting a target exercise heart rate that reflects the anaerobic threshold in non-beta-blocked hemodialysis patients: the Karvonen and Heart Rate Reserve formulas
■ 概要
  The aim of this study was to evaluate constants of the Karvonen and Heart Rate Reserve (HRR) formulas that correspond to the anaerobic threshold (AT) to conveniently estimate the intensity of exercise therapy in non-beta-blocked patients undergoing hemodialysis. Twenty-three patients undergoing hemodialysis performed cardio-pulmonary exercise testing and their HR at AT was measured. The predictor coefficients for a target HR corresponding to AT were calculated for each patient based on cardio-pulmonary exercise testing. Mean values of coefficient k of the Karvonen formula and α of the HRR formula were 0.24 ± 0.11 and 17.4 ± 8, respectively.
