“…Whether different exercise intensity parameters correspond with each other has been studied before, but with mixed outcomes and often in smaller studies (maximal n=115). [18][19][20][21] A more recent study involving 141 patients with heart disease found that the use of HR to determine a proper exercise intensity should be done cautiously due to a high inter-patient variance. 22 It thus follows that these more recent data are well in line with our findings.…”

Aims In the rehabilitation of cardiovascular disease patients a correct determination of the endurance-type exercise intensity is important to generate health benefits and preserve medical safety. It remains to be assessed whether the guideline-based exercise intensity domains are internally consistent and agree with physiological responses to exercise in cardiovascular disease patients. Methods A total of 272 cardiovascular disease patients without pacemaker executed a maximal cardiopulmonary exercise test on bike (peak respiratory gas exchange ratio >1.09), to assess peak heart rate (HRpeak), oxygen uptake (VO2peak) and cycling power output (Wpeak). The first and second ventilatory threshold (VT1 and VT2, respectively) was determined and extrapolated to %VO2peak, %HRpeak, %heart rate reserve (%HRR) and %Wpeak for comparison with guideline-based exercise intensity domains. Results VT1 was noted at 62 ± 10% VO2peak, 75 ± 10% HRpeak, 42 ± 14% HRR and 47 ± 11% Wpeak, corresponding to the high intensity exercise domain (for %VO2peak and %HRpeak) or low intensity exercise domain (for %Wpeak and %HRR). VT2 was noted at 84 ± 9% VO2peak, 88 ± 8% HRpeak, 74 ± 15% HRR and 76 ± 11% Wpeak, corresponding to the high intensity exercise domain (for %HRR and %Wpeak) or very hard exercise domain (for %HRpeak and %VO2peak). At best (when using %Wpeak) in only 63% and 72% of all patients VT1 and VT2, respectively, corresponded to the same guideline-based exercise intensity domain, but this dropped to about 48% and 52% at worst (when using %HRR and %HRpeak, respectively). In particular, the patient’s VO2peak related to differently elicited guideline-based exercise intensity domains ( P < 0.05). Conclusion The guideline-based exercise intensity domains for cardiovascular disease patients seem inconsistent, thus reiterating the need for adjustment.

“…Two of the participants in this study were taking ␤-blockers, which are known to lower heart rate (HR). According to Chaloupka et al (5), the percent peak HR (HR peak) can be used to determine exercise training intensity in patients treated with ␤-blockers. One of the men in the control group had to increase the levels of statins 3 wk before the posttest.…”

J Appl Physiol 108: 804-810, 2010. First published January 21, 2010 doi:10.1152/japplphysiol.00996.2009.-Metabolic syndrome is characterized by central obesity, elevated blood pressure, high fasting glucose and triglyceride levels, and low HDL levels. Regular physical activity can improve the metabolic profile and reduce the risks of cardiovascular diseases and premature mortality. However, the optimal training regime to treat metabolic syndrome and its associated cardiovascular abnormalities remains undefined. Fortythree participants with metabolic syndrome were randomized to one of the following groups: aerobic interval training (AIT; n ϭ 11), strength training (ST; n ϭ 11), a combination of AIT and ST (COM; n ϭ 10) 3 times/wk for 12 wk, or control (n ϭ 11). Risk factors comprising metabolic syndrome were evaluated before and after the intervention. Waist circumference (in cm) was significantly reduced after AIT [95% confidence interval (CI): Ϫ2.5 to Ϫ0.04], COM (95% CI: Ϫ2.11 to Ϫ0.63), and ST (95% CI: Ϫ2.68 to Ϫ0.84), whereas the control group had an increase in waist circumference (95% CI: 0.37-2.9). The AIT and COM groups had 11% and 10% increases in peak O2 uptake, respectively. There were 45% and 31% increases in maximal strength after ST and COM, respectively. Endothelial function, measured as flow-mediated dilatation (in %), was improved after AIT (95% CI: 0.3-3), COM (95% CI: 0.3-3), and ST (95% CI:

“…When taking b-blockers patients have lower heart rates during exercise than without this medication, but it is still valid to prescribe exercise intensity by % of (b-blocked) heart rate maximum. 19 Although patients were supposed to take b-blockers, we had no formal control of this, and non-adherence to the prescribed medication could affect the heart rate recordings in the study.…”

Aerobic interval training increases peak oxygen uptake more than usual care exercise training in myocardial infarction patients: a randomized controlled study

Exercise Intensity Prescription After Myocardial Infarction in Patients Treated With Beta-blockers

Abstract: As an upper limit in determining training intensities, the assessment of AT is the gold standard. However, findings suggest that %HRpeak, %HRR, and %VO2peak can be used alternatively. The use of workload expressed as in W/kg also appears useful.
