Establishing cut-points for physical activity classification using triaxial accelerometer in middle-aged recreational marathoners
2018
The purpose of this study was to establish GENEA (Gravity Estimator of Normal Everyday Activity) cut-points for discriminating between six relative-intensity activity levels in middle-aged recreational marathoners. Nighty-eight (83 males and 15 females) recreational marathoners, aged 30-45 years, completed a cardiopulmonary exercise test running on a treadmill while wearing a GENEA accelerometer on their non-dominant wrist. The breath-by-breath V̇O2 data was also collected for criterion measure of physical activity categories (sedentary, light, moderate, vigorous, very vigorous and extremely vigorous). GENEA cut-points for physical activity classification was performed via Receiver Operatin…
Ekspiratorisk flow avgrensingar under fysisk belastning hos ungdommar med astma : Før og etter 10 vekers intervensjon
2019
Masteroppgave folkehelsevitenskap ME516 - Universitetet i Agder 2019 Background:Asthma is a chronic inflammatory disorder associated with variable airflo w obstruction and bronchial hyperresponsivness. Asthma may interfere with the ability of childre n and adolescents to participatein physical activity, as well ascreatebarriers towards involvement. Physical activity is an important stimulus for asthma symptoms. Exercise-induced bronchoconstriction is traditionally used when physical activity is the cause of asthma symptoms, but this is measured after exercise. There is little knowledge about flow limitat io n during exercise. Aim:The purpose of this study is to investigate expiratory flow l…
Relative peak exercise oxygen pulse is related to sudden cardiac death, cardiovascular and all-cause mortality in middle-aged men
2018
Background Preliminary evidence suggests that peak exercise oxygen pulse – peak oxygen uptake/heart rate-, a variable obtained during maximal cardiopulmonary exercise testing and a surrogate of stroke volume, is a predictor of mortality. We aimed to assess the associations of peak exercise oxygen pulse with sudden cardiac death, fatal coronary heart disease and cardiovascular disease and all-cause mortality. Design A prospective study. Methods Peak exercise oxygen pulse was assessed in a maximal cycling test at baseline in 2227 middle-aged men of the Kuopio Ischaemic Heart Disease cohort study using expired gas variables and electrocardiograms. Relative peak exercise oxygen pulse was obtain…
Delayed Anaerobic Threshold in Heart Failure Patients With Atrial Fibrillation
2016
PURPOSE To assess whether atrial fibrillation (AF) in heart failure (HF) affects oxygen uptake at anaerobic threshold ((Equation is included in full-text article.)O2 AT) and heart rate (HR) kinetics. METHODS A total of 15 patients with HF and AF and 18 with HF and sinus rhythm (SR) performed a maximal incremental and 2 constant workload cycle ergometer cardiopulmonary exercise tests (below and above AT, at 25% and 75% of maximal workload, respectively). At constant workload tests, kinetics of (Equation is included in full-text article.)O2 and HR were assessed by calculating time constant (τ). RESULTS HF patients with AF showed a similar peak (Equation is included in full-text article.)O2 to…
Ultra Trail Performance is Differently Predicted by Endurance Variables in Men and Women
2020
AbstractThe study aimed to assess the relationship between peak oxygen uptake, ventilatory thresholds and maximal fat oxidation with ultra trail male and female performance. 47 athletes (29 men and 18 women) completed a cardiopulmonary exercise test between 2 to 4 weeks before a 107-km ultra trail. Body composition was also analyzed using a bioelectrical impedance weight scale. Exploratory correlation analyses showed that peak oxygen uptake (men: r=–0.63, p=0.004; women: r=–0.85, p < 0.001), peak speed (men: r=–0.74, p < 0.001; women: r=–0.69, p=0.009), speed at first (men: r=–0.49, p=0.035; women: r=–0.76, p=0.003) and second (men: r=–0.73, p < 0.001; women: r=–0.76, p=0.003) vent…
Cardiorespiratory Fitness and Physical Activity following Lung Transplantation: A National Cohort Study
2020
<b><i>Background:</i></b> Low cardiorespiratory fitness and inactivity are common after lung transplantation (LTx). The causes of exercise intolerance are incompletely understood. <b><i>Objectives:</i></b> The aim of this study was to objectively assess cardiorespiratory fitness and physical activity, evaluate causes of exercise intolerance, and explore clinical factors associated with cardiorespiratory fitness after bilateral LTx (BLTx). <b><i>Materials and Methods:</i></b> Peak oxygen uptake (V<b>∙</b>O<sub>2peak</sub>) and exercise-limiting factors were evaluated by a treadmill cardiopulmonary…
Progressive right ventricular dysfunction and exercise impairment in patients with heart failure and diabetes mellitus: insights from the T.O.S.CA. R…
2022
Abstract Background Findings from the T.O.S.CA. Registry recently reported that patients with concomitant chronic heart failure (CHF) and impairment of insulin axis (either insulin resistance—IR or diabetes mellitus—T2D) display increased morbidity and mortality. However, little information is available on the relative impact of IR and T2D on cardiac structure and function, cardiopulmonary performance, and their longitudinal changes in CHF. Methods Patients enrolled in the T.O.S.CA. Registry performed echocardiography and cardiopulmonary exercise test at baseline and at a patient-average follow-up of 36 months. Patients were divided into three groups based on the degree of insulin impairmen…

Cardiopulmonary exercise testing in COVID-19 patients at 3 months follow-up
2021
Abstract Background Long-term effects of Coronavirus Disease of 2019 (COVID-19) and their sustainability are of the utmost relevance. For the chronic phase, the main concerns are the development of pulmonary interstitial disease and/or lingering cardiovascular involvement. How to intercept, assess, and treat these patients with long-term consequences of COVID-19 remains uncertain. Purpose We aimed to determine: 1) functional capacity of COVID-19 survivors by cardiopulmonary exercise testing (CPET); 2) those characteristics associated with CPET performance; 3) safety and tolerability of CPET. Methods We prospectively enrolled consecutive patients with laboratory-confirmed COVID-19 discharged…
