“…The differences between our findings and the results of other studies might be explained by the relatively small number of patients and the apparent lack of hypercapnia. Some authors have proposed that respiratory factors were more responsible than cardiovascular factors in exercise limitation in COPD, and so exercise testing should be performed to the maximal level in those patients 16,45 . In our study, all patients stopped the test due to dyspnoea.…”

“…The choice, in our study, to focus exclusively on the HR arises from the observation that this variable is easily specified by the clinician, understandable and observable for the patient, easy to measure (by HR sensor or pulse taken at the wrist), can be used in a variety of environments and during many forms of exercise (biking, walking, gardening), and easy and cheap to use when the patient is alone at the exit of the PR program. Thereby, Simmons et al36 demonstrated the utility of using the HR as a marker for the intensity of the exercise.…”

BackgroundIt has been scientifically proven that pulmonary rehabilitation improves exercise tolerance and facilitates the carrying out of daily physical activities. To optimize the physical and physiological benefits, it is necessary to individualize the training intensity for each patient. The aim of this study is to compare the heart rate (HR) responses to three exercise modalities measuring aerobic fitness in chronic obstructive pulmonary disease patients, in order to easily prescribe individual target HRs for endurance training.Patients and methodFifty COPD patients (mean age: 60.1±8.5 years) were included in the study. Each patient carried out a cardiopulmonary exercise test, a 6-minute walk test (6MWT) and a 6-minute stepper test (6MST). During these tests, HR was recorded continuously. After the cardiopulmonary exercise test, the HR was noted at the ventilatory threshold (VT) and at the end of the two exercise field tests (6MWTpeak and 6MSTpeak). The values of the HR during the last 3 minutes of both field tests were averaged (6MWT456 and 6MST456). Finally, the HR at 60% of the HR reserve was calculated with the values of the HR measured during 6MWT and 6MST (HRr60%walk, HRr60%step).ResultsThe HRs measured during the 6MST were significantly higher than those measured during the 6MWT. The HRr60%step was not significantly different from 6MWT456 and 6MWTpeak HR (P=0.51; P=0.48). A significant correlation was observed between 6MWT456 and 6MWTpeak (r=0.58). The 6MWT456 and 6MWTpeak HR were correlated with HRr60%step (r=0.68 and r=0.62). The VT could be determined in 28 patients. The HRVT was not different from 6MWT456, 6MWTpeak, and HRr60%step (P=0.57, P=0.41 and P=0.88) and was correlated to 6MWT456, 6MWTpeak, and HRr60%step (r=0.45, r=0.40, r=0.48).ConclusionAn individualized target HR for endurance training can be prescribed from the HR measured during routine tests, such as 6MWT or 6MST.

Abstract! Background: Exercise training is an integral component of the management of patients with asthma and COPD. A training intensity of 60 ± 80 % of maximum oxygen uptake (VO 2 max) has been recommended. Instead of ergospirome− try measurement of heart rate can be used for training guidance. It is unknown whether the given target can be reached in outpatient training groups with substantial heterogeneity concering diagnosis, disease severity, and age. Methods and patients: 61 adult patients (m = 15, w = 46; 63 9 years) with asthma (n = 50) or COPD (n = 11) exercised in groups of ambulant lung sports. An individualized target heart rate was calculated corresponding to an intensity of 60 % to 80 % of calculated VO 2 max which was equiva− lent to a heart rate from 97 to 137 beats per mi− nute in the population studied. Heart reate, as a measure of the intensity of charge, was measured continuously with pulse frequency meters. Results: All but one asthma patient exercised in the targeted heart rate range. Patients reached 81 9 % of the training goal of calculated 80 % VO 2 max (asthma patients: 79 9 % vs. COPD pa− tients: 88 9 %, p < 0,005) No significant diffe− rences regarding training intensities were obser− ved in relation to severity of illness or age. Conclusions: In outpatient lung sport groups of considerable heterogeneity regarding diagnosis, severity of illness and age, participants reach their individualized heart rate target range. COPD patients were training at a significantly higher relative training intensity. Heart rate is an easy to use parameter for training guidance.

The relationship between %HRpeak and %&OV0312;O2peak in patients with chronic obstructive pulmonary disease

Abstract: In conclusion, the relationship between %HRpeak and %VO2peak described by ACSM is not applicable to patients with COPD. Furthermore, this relationship does not change with exercise training and can be described by a single equation.
