COPHYD (Corona Owed Physical Deficiency): The Impact of Lockdown on Cardiopulmonary Function in Paediatric Cardiology Patients.

INTRODUCTION: Due to the Corona-lockdowns the closure of sports facilities and schools has led to a decline in physical activity (PA) for months. PA is essential for maintaining cardiopulmonary function assessed by peak oxygen uptake. Since peak oxygen uptake represents the best predictor for mortality and morbidity in children with congenital heart disease the impact of lockdowns on this parameter is vital. METHODS: We evaluated retrospectively cardiopulmonary exercise data from our patient collective from before lockdown with twin-paired data from during lockdown. The twin-pairing was achieved by matching patients with similar heart disease, age, sex, and test method. Cardiopulmonary exercise testing was achieved on either the treadmill or the bicycle. RESULTS: We were able to twin-pair 90 cases (26 twins with heart disease and 19 healthy twins). There was a significant decrease of cardiopulmonary function (V̇O2peak: 35.7±9.8 vs.30.4±10.6) in the heart disease cohort along with a significant decrease in peak oxygen pulse (13.3±4.1 vs. 11.4±4.5), and peak minute ventilation (V ̇E: 83.05±29.08 vs.71,49±24.96). The healthy children improved over the timeframe, but this only reached significance for peak minute ventilation (81.72±25.79 vs.97.94±31.4). CONCLUSION: We observed a significant decline of peak oxygen uptake during lockdown in the group of congenital heart disease (CHD) patients. This involved a loss of cardiac function as well as pulmonary function. This could be explained by limited access to sports facilities and restriction of regular daily movement due to school closure and overprotection. Healthy children improved their pulmonary function. This might be an indication of an improvement of exercise during confinement.Aufgrund des Corona-Lockdowns hat die Schließung von Sportanlagen und Schulen über Monate zu einem Rückgang der körperlichen Aktivität geführt. Körperliche Aktivität ist für die Aufrechterhaltung der kardiopulmonalen Funktion, bewertet durch die maximale Sauerstoffaufnahme, unerlässlich. Da die maximale Sauerstoffaufnahme der beste Prädiktor für Mortalität und Morbidität bei Kindern mit angeborenen Herzerkrankungen ist, sind die Auswirkungen des Lockdowns auf diesen Parameter von entscheidender Bedeutung. Spiroergometriedaten unseres Patientenkollektivs aus der Zeit vor dem Lockdown wurde mit Daten von statistischen Zwillingen aus dem gleichen Kollektiv während des Lockdowns verglichen. Die Zwillingspaarung wurde erreicht, indem Patienten mit ähnlichen Herzerkrankungen, Alter, Geschlecht und Testmodalitäten verglichen wurden. Die Spiroergometrie wurde entweder auf dem Laufband oder auf dem Fahrrad durchgeführt. Insgesamt wurden 90 Datensätze verbunden (26 Zwillinge mit Herzkrankheit und 19 gesunde Zwillinge). In der Kohorte der Herzerkrankten konnte eine signifikante Verschlechterung der kardiopulmonalen Funktion (V̇O2peak: 35,7±9,8 vs. 30,4±10,6), des Spitzensauerstoffpulses (O2puls: 13,3±4,1 vs. 11,4±4,5) und der Spitzenminutenventilation (VE: 83,05 ± 29,08 vs. 71,49 ± 24,96) beobachtet werden. Die gesunden Kinder verbesserten sich im Laufe der Zeit, wobei der Anstieg nur bei der Spitzenminutenventilation (81,72±25,79 vs. 97,94 ± 31,4) signifikant war. in der Kohorte der Patienten mit angeborenen Herzerkrankungen (CHD) beobachteten wir einen deutlichen Rückgang der maximalen Sauerstoffaufnahme während des Lockdowns. Dies liegt begründet in einer Verschlechterung der Herz-, sowie der Lungenfunktion. Erklärung dafür könnte der begrenzte Zugang zu Sporteinrichtungen, sowie Einschränkungen der täglichen Bewegungsfreiheit durch Schulschließungen und Überbehütung sein. Gesunde Kinder konnten ihr Atemminutenvolumen während dem Lockdown steigern und zeigten einen Trend zu besserer Belastbarkeit. Dies könnte auf eine Zunahme der körperlichen Bewegung während des Lockdowns hindeuten.

Physiological Effects of Training in Elite German Winter Sport Athletes: Sport Specific Remodeling Determined Using Echocardiographic Data and CPET Performance Parameters.

Nine ski mountaineering (Ski-Mo), ten Nordic-cross country (NCC), and twelve world elite biathlon (Bia) athletes were evaluated for cardiopulmonary exercise test (CPET) performance and pronounced echocardiographic physiological cardiac remodeling as a primary aim of our descriptive preliminary report. In this context, a multicenter retrospective analysis of two-dimensional echocardiographic data including speckle tracking of the left ventricle (LV-GLS) and CPET performance analysis was performed in 31 elite world winter sports athletes, which were obtained during the annual sports medicine examination between 2020 and 2021. The matched data of the elite winter sports athletes (14 women, 17 male athletes, age: 18-32 years) were compared for different CPET and echocardiographic parameters, anthropometric data, and sport-specific training schedules. Significant differences could be revealed for left atrial (LA) remodeling by LA volume index (LAVI, p = 0.0052), LV-GLS (p = 0.0003), and LV mass index (LV Mass index, p = 0.0078) between the participating disciplines. All participating athletes showed excellent performance data in the CPET analyses, whereby significant differences were revealed for highest maximum respiratory minute volume (VE maximum) and the maximum oxygen pulse level across the participating athletes. This study on sport specific physiological demands in elite winter sport athletes provides new evidence that significant differences in CPET and cardiac remodeling of the left heart can be identified based on the individual athlete's training schedule, frequency, and physique.

Physiological Aspects of World Elite Competitive German Winter Sport Athletes

Nine Ski mountaineering (Ski-Mo), ten Nordic-Cross Country (NCC) and twelve world elite biathlon (Bia) athletes were evaluated for cardiopulmonary exercise test (CPET) performance as the primary aim of our descriptive preliminary report. A multicenter retrospective analysis of CPET data was performed in 31 elite winter sports athletes, which were obtained in 2021 during the annual medical examination. The matched data of the elite winter sports athletes (14 women, 17 male athletes, age: 18–32 years) were compared for different CPET parameters, and athlete’s physique data and sport-specific training schedules. All athletes showed, as estimated in elite winter sport athletes, excellent performance data in the CPET analyses. Significant differences were revealed for VE VT2 (respiratory minute volume at the second ventilatory threshold (VT2)), highest maximum respiratory minute volume (VEmaximum), the indexed ventilatory oxygen uptake (VO2) at VT2 (VO2/kg VT2), the oxygen pulse at VT2, and the maximum oxygen pulse level between the three professional winter sports disciplines. This report provides new evidence that in different world elite winter sport professionals, significant differences in CPET parameters can be demonstrated, against the background of athlete’s physique as well as training control and frequency.

Athlete's Heart in Elite Biathlon, Nordic Cross-Country and Ski-Mountaineering Athletes: Cardiac Adaptions Determined Using Echocardiographic Data.

Twelve world elite Biathlon (Bia), ten Nordic Cross Country (NCC) and ten ski-mountaineering (Ski-Mo) athletes were evaluated for pronounced echocardiographic physiological cardiac remodeling as a primary aim of our descriptive preliminary report. In this context, sports-related cardiac remodeling was analyzed by performing two-dimensional echocardiography including speckle tracking analysis as left ventricular global longitudinal strain (LV-GLS). A multicenter retrospective analysis of echocardiographic data was performed in 32 elite world winter sports athletes, which were obtained between 2020 and 2021 during the annual medical examination. The matched data of the elite world winter sports athletes (14 women, 18 male athletes, age: 18-35 years) were compared for different echocardiographic parameters. Significant differences could be revealed for left ventricular systolic function (LV-EF, p = 0.0001), left ventricular mass index (LV Mass index, p = 0.0078), left atrial remodeling by left atrial volume index (LAVI, p = 0.0052), and LV-GLS (p = 0.0003) between the three professional winter sports disciplines. This report provides new evidence that resting measures of cardiac structure and function in elite winter sport professionals can identify sport specific remodeling of the left heart, against the background of training schedule and training frequency.
