“…31 Heart failure patients can manage to use the Borg scale well and its use guarantees a submaximal effort in the 6-min walking test. 7 The Borg scale also can be quite useful in prescribing exercise training intensity. 32 In the present study, the patients did not have any difficulties understanding the exercise training as guided by the Borg scale.…”

“…Encouragement was standardized with phrases such as "If you can walk faster, increase the speed", "You are doing very well", and "If it is tiring, you can reduce the speed". 7 All patients used a HR monitor (Polar, Electro Oy, Kempele, Finland) that continuously showed the HR throughout the 30-min exercise session and the mean HR immediately after the study exercise protocol. The investigator checked each patient's HR every 5 min during the exercise training.…”

“…18 In this population of patients, the prescription of adequate aerobic exercise intensity based on heart rate (HR) is crucial to ensure both an increase in exercise capacity and reasonable control of exercise-related risk. 1,7 Despite the lack of consensus about which exercise method and intensity are the best to improve heart failure patients, a submaximal level (ie, between the anaerobic threshold and respiratory compensation point) seems to have the best security/efficacy relationship. 19 Higher exercise intensities are associated with displeasure 20 and reduced adherence.…”

“…Exercise guided by the Borg Scale of between "relatively easy and slightly tiring" has been proposed to guarantee submaximal effort during exercise. 7 Despite the importance of exercise intensity, little is known about the self-monitoring and self-regulating of exercise intensity by heart failure patients, particularly during hydrotherapy.…”

Background:The Borg Scale may be a useful tool for heart failure patients to self-monitor and self-regulate exercise on land or in water (hydrotherapy) by maintaining the heart rate (HR) between the anaerobic threshold and respiratory compensation point. Methods and Results: Patients performed a cardiopulmonary exercise test to determine their anaerobic threshold/respiratory compensation points. The percentage of the mean HR during the exercise session in relation to the anaerobic threshold HR (%EHR-AT), in relation to the respiratory compensation point (%EHR-RCP), in relation to the peak HR by the exercise test (%EHR-Peak) and in relation to the maximum predicted HR (%EHR-Predicted) was calculated. Next, patients were randomized into the land or water exercise group. One blinded investigator instructed the patients in each group to exercise at a level between "relatively easy and slightly tiring". The mean HR throughout the 30-min exercise session was recorded. The %EHR-AT and %EHR-Predicted did not differ between the land and water exercisegroups, but they differed in the %EHR-RCP (95±7 to 86±7, P<0.001) and in the %EHR-Peak (85±8 to 78±9, P=0.007). Conclusions: Exercise guided by the Borg scale maintains the patient's HR between the anaerobic threshold and respiratory compensation point (ie, in the exercise training zone).
