چکیده

Despite described benefits of aerobic high-intensity interval exercise (hiie),the acute responses during different hiie modes and associated health risks have only been sparsely dis-covered in heart disease patients. therefore,the aim of this study was to investigate the acute responses for physiological parameters,cardiovascular and inflammatory biomarkers,and catecholamines yielded by two different aerobic hiie protocols compared to continuous exercise (ce) in phase iii cardiac reha-bilitation. eight cardiac patients (7 with coronary heart disease,1 with myocarditis; 7 males,1 female; age: 63.0 ± 9.4 years; height: 1.74 ± 0.05 m; weight: 83.6 ± 8.7 kg),all but one treated with ß-blocking agents,performed a maximal symptom-limited incremental exercise test (iet) and three different exercise tests matched for mean load (pmean) and total duration: 1) short hiie with a peak workload duration (tpeak) of 20 s and a peak work-load (ppeak) equal to the maximum power output (pmax) from iet; 2) long hiie with a tpeak of 4 min,ppeak was corresponding to the power output at 85 % of maximal heart rate (hrmax) from iet; 3) ce with a target workload equal to pmean of both hiie modes. acute metabolic and peak cardiorespiratory responses were significantly higher during long hiie compared to short hiie and ce (p < 0.05) except hrpeak which tended to be higher in long hiie than in short hiie (p = 0.08). between short hiie and ce,no significant difference was found for any parameter. acute responses of cardiovascular and inflammatory biomarkers and catecholamines didn’t show any significant difference be-tween tests (p > 0.05). all health-related variables remained in a normal range in any test except nt-probnp,which was already elevated at baseline. despite a high ppeak particularly in short hiie,both hiie modes were as safe and as well tolerated as moderate ce in cardiac patients by using our methodological approach. © journal of sports science and medicine
