Abstract Funding Acknowledgements Type of funding sources: None. Introduction Exercise capacity and ventilatory efficiency are often altered in hypertrophic cardiomyopathy (HCM) several factors have been advocated as possible causes. Aim This study investigates the determinants cardiopulmonary exercise test (CPET) prognostic markers for HCM (VO2Peak, VE/VCO2 Slope PETCO2 apex), by considering e...

BACKGROUND It is well established that the work rate increment size affects the duration of test and physiological responses to exercise during cycling in patients with COPD. However, this has never been tested for incremental step tests. OBJECTIVE To compare the exercise tolerance time, cardiopulmonary stress, and perception of effort between the Chester step test (CST) and a modified incre...

BACKGROUND Although sports participation is allowed to most adult patients with corrected tetralogy of Fallot, a reduced exercise tolerance and reduced perceived physical functioning is often present in these patients. We aimed to investigate daily physical activity in adults with tetralogy of Fallot and to investigate the underlying determinants of physical activity in daily life. METHODS We...

OBJECTIVES To compare the psychological responses to continuous (CT) and high-intensity interval training (HIT) sessions. METHODS Fifteen men attended one CT session and one HIT session. During the first visit, the maximum heart rate, VO2Peak and respiratory compensation point (RCP) were determined through a maximal cardiopulmonary exercise test. The HIT stimulus intensity corresponded to 100...

PURPOSE Aerobic training has been shown to be effective in improving cardiopulmonary fitness in asthmatic children. However, the actual impact of physical training on clinical indicators of disease control remains controversial. METHODS Thirty-eight children with moderate to severe persistent asthma were randomly assigned to control (N=17) and training (N=21) groups. Spirometry, exercise chal...

The aim of this study was to clarify the mechanism of impaired exercise tolerance in chronic sleep-restricted conditions by investigating variables related to heart-rate (HR) response to sympathetic nervous stimulation. Sixteen healthy men (mean age 21.5 years) were tested in a control state, acute sleep-loss state, and chronic sleep-restricted state. Participants underwent cardiopulmonary exer...

OBJECTIVE This study aimed to compare respiratory responses, focusing on the time-domain variability of ventilatory components during progressive cardiopulmonary exercise tests performed on cycle or arm ergometers. METHODS The cardiopulmonary exercise tests were conducted on twelve healthy volunteers on either a cycle ergometer or an arm ergometer following a ramp protocol. The time-domain va...
