Regarding to the participants conditions in terms of heart rate reserve percentage was specified intensity & during time of activity & periodic planning
The optimal exercise intensity for improving cardiovascular fitness in persons with spinal cord injuries still needs to established, however, based on research to date, a range of 50 to 80% of the heart rate reserve (HRR) has been recommended, with the higher training intensities (70--80% HRR) showing greater improvements in cardiovascular function (Wharburton et al 2012).
Participants remained at rest for one hour, followed by 60 minutes of running at 70% heart rate reserve on a motorized treadmill.
Use of heart rate reserve and rating of perceived exertion to prescribe exercise intensity in diabetic autonomic neuropathy.
Following a warm up period, subjects walked at intensities corresponding to 30%, 40%, 50%, and 60% of heart rate reserve (%HRR) calculated using Karvonen's formula (Activity HR = [% (HR age predicted maximal-HR rest)]-HR rest) (ACSC 2000) reaching steady state for each intensity level.
The Karvonen method was used to estimate heart rate reserve: 70% heart rate reserve = (220 - age - resting heart rate) X (0.
After resting heart rate was obtained, subjects were taken to a private room where they practiced riding an electronically braked bicycle ergometer at a work rate which corresponded to 60-75% of individual heart rate reserve.

The subjects were randomly assigned to three exercise groups: those beginning a regimen at 25% of heart rate reserve and gradually working up to 40% over a 10-week period; those beginning at 40% of heart rate reserve and working to 60% over 10 weeks; and a control group participating in no exercise over the 10-week period.
There is also the Karvonen, or heart rate reserve method, used to calculate heart rate zones.
