Progression of Intensity and Target Heart Rate (HR) Duration During Aerobic Exercise Interventiona
↵a V̇o2R=oxygen uptake reserve, individually calculated for participants on the basis of the results of the graded maximal exercise test. Average heart rate target values were 102.4 (SD=11.7) beats per minute (bpm) for 50% V̇o2R, 109.5 (SD=13.3) bpm for 60% V̇o2R, and 115.8 (SD=14.7) bpm for 70% V̇o2R.
