Here, we present evidence that replacement of half of the usually prescribed continuous exercise training sessions in cardiac rehabilitation with high-intensity interval training sessions affects these trajectories. High-intensity interval training shifts the nadirs of ventilatory equivalents for O2 and CO2 and the subsequent rise to load terminati...

Introduction Epidemiological studies show that increased physical activity is linked to a lower risk of breast cancer and mortality. As a result, physical activity can significantly improve patients' quality of life (QOL) both during and after therapy. Many breast cancer patients demonstrate a decrease in cognitive capacity, referred to as the symp...

Medical rehabilitation is traditionally considered to consist of an inpatient stay, but since 2000 there have also been outpatient offerings where patients can receive their treatment in their familiar family and social environment. The medical benefit profile for this type of rehabilitation is drawn up by the pension insurance. Although gastroente...

Aim Cardiac rehabilitation (CR) is a key component of the treatment of cardiac diseases. The Austrian outpatient CR model is unique, as it provides patients with an extended professionally supervised, multidisciplinary program of 4–6 weeks of phase II (OUT-II) and 6–12 months of phase III (OUT-III) CR. The aim of this analysis was to assess the eff...

Objective: To compare effects of moderate intensity continuous training (MICT) and high intensity interval training (HIIT) on platelet function in patients undergoing cardiac rehabilitation, as hyperreactive platelets are involved in atherogenesis and atherothrombosis. Methods: In this single-centre parallel group randomised controlled trial male...

The heart rate (HR) rises with increased power output, whereby in most healthy individuals the slope of HR levels off with higher intensity. This corresponds to a downward deflection of the heart rate performance curve (HRPC). Conversely, in patients after myocardial infarction, an upward HRPC deflection is frequently observed that is especially pr...

Research has shown that physical activity is essential in the prevention and treatment of chronic diseases like cardiovascular disease (CVD). Smart wearables (e.g., smartwatches) are increasingly used to foster and monitor human behaviour, including physical activity. However, despite this increased usage, little evidence is available on the effect...

Die Zusammensetzung der Atemluft ist bekanntlich: O2: 21%, N2: 78,1%, Edelgase: 0,9%. Unter regulären Druckverhältnissen, wie sie auf Meereshöhe an der Wasseroberfläche herrschen, nimmt Stickstoff an keinerlei Stoffwechselprozessen im Körper teil und wird demzufolge als Inertgas bezeichnet. Beim SportSporttauchen- oder Freizeittauchen wird entweder...

Die ersten Aktivitäten im Behindertensport sind aus dem 18. Jahrhundert überliefert, den wirklichen Aufschwung jedoch erlebte der Behindertensport erst nach den beiden Weltkriegen. Einen Meilenstein setzte Sir Ludwig Guttmann, der in England ein Rehabilitationszentrum für Rückenmarkserkrankungen aufbaute und damit begann, Sport und körperliche Akti...

In this study, we investigate the effects of using smart wearables by patients undergoing cardiac rehabilitation. A field experiment involving 29 patients was designed and participants were either assigned to the study group (N=13 patients who finished the study and used a self-tracking device) or the control group (N=16 patients who finished the s...

To evaluate cardiorespiratory and hemodynamic responses during 24h of continuous cycle ergometry in ultra-endurance athletes. Eight males (mean±SD age: 39±8 yrs, height (Ht): 179±7 cm, body weight (Wt): 77.1±6.0 kg) were monitored over 24h at a constant workload,∼25% below the first lactate turn point (LTP1) at 162±23 Watts (W). Measurements includ...

Empfehlungen zur Modifizierung des Lebensstils einschließlich körperlichen Trainings sind die Basis der Therapie bei allen kardiovaskulären und metabolischen Erkrankungen. Der günstige Einfluß von regelmäßigem körperlichem Training auf die Morbidität und Mortalität von Herz-Kreislauf-Erkrankungen ist ausreichend belegt. Körperliches Training gehört...

Recommendations for lifestyle changes which involve physical exercise are cornerstones of a comprehensive treatment strategy in cardiovascular and metabolic disorders. The positive influence of physical exercise to morbidity and mortality of cardiovascular diseases is well evidenced by literature. Therefore physical activity should be part of prima...
