The Intra-rater and Inter-rater Reliability of measures derived from Cardiopulmonary Exercise Testing (CPET) in patients with Abdominal Aortic Aneurysms (AAA).

Patients with abdominal aortic aneurysms (AAA) often have low exercise tolerance due to comorbidities and advance age. Cardiopulmonary exercise testing (CPET) is predictive of post-operative morbidity and mortality in patients with AAA. We aimed to assess the intra- and inter-rater reliability of both treadmill and cycle ergometer based CPET variables.

Predicted Equation for VO2 Based on a 20-Meter Multistage Shuttle Run Test for Children.

This study compared maximum oxygen consumption (VOmax) on a 20-meter multistage shuttle run test (20-Srt) with a cardiopulmonary exercise test (CPET) to determine a VOmax prediction equation for a 20-Srt in children aged 6-10 years. Eighty healthy children performed the CPET on a treadmill, while the 20-Srt took place on a sports court. Heart rate (HR) was measured and the expired gases were continuously measured breath-by-breath using a portable gas analyzer. The VOmax was lower (p

O2 Pulse Patterns in Male Master Athletes with Normal and Abnormal Exercise Tests.

The clinical relevance of abnormal exercise testing (ET) results (at least 0.1 mV ST-segment depression measured during exercise or recovery in three consecutive beats) in athletes without obstructive coronary artery disease (CAD) is not well understood. It is unknown whether this phenomenon reflects a physiological adaptation to sport or a truly ischemic response and a concomitant attenuated stroke volume (SV) response. The aim of this study was to investigate if athletes with abnormal ET results without o...

Cardiorespiratory and metabolic responses and reference equation validation to predict peak oxygen uptake for the incremental shuttle waking test in adolescent boys.

Previous studies speculated that the Incremental Shuttle Walking Test (ISWT) is a maximal test in children and adolescents, however comparison between ISWT with cardiopulmonary exercise test has not yet performed. Furthermore, there is no regression equation available in the current literature to predict oxygen peak consumption (VO2 peak) in this population. This study aimed to assesses and correlate the cardiorespiratory responses of the ISWT with the cardiopulmonary exercise (CEPT) and to develop and vali...

Comprehensive effects of left ventricular assist device speed changes on alveolar gas exchange, sleep ventilatory pattern, and exercise performance.

Increasing left ventricular assist device (LVAD) pump speed according to the patient's activity is a fascinating hypothesis. This study analyzed the short-term effects of LVAD speed increase on cardiopulmonary exercise test (CPET) performance, muscle oxygenation (near-infrared spectroscopy), diffusion capacity of the lung for carbon monoxide (Dlco) and nitric oxide (Dlno), and sleep quality.

Which Cut-offs for Secondary VCombining Dot AboveO2max Criteria Are Robust to Diurnal Variations?

The aim was to determine the minimum secondary exhaustion criteria cut-offs (i.e. max respiratory exchange ratio [RERmax], max heart rate [HRmax], max rating of perceived exertion [RPEmax], and max blood lactate concentration [BLmax]) necessary to determine maximum oxygen uptake (VO2max) during cardiopulmonary exercise tests (CPET), by balancing type I and type II errors. A further aim was to investigate if the defined cut-offs would be robust to diurnal and to day-to-day variations.

Dynamics of cardiorespiratory response during and after the six-minute walk test in patients with heart failure.

The six-minute walk test (6MWT) is a useful measure to evaluate exercise capacity with a simple method. The kinetics of oxygen uptake ([Formula: see text]O) throughout constant-load exercise on cardiopulmonary exercise testing (CPX) are composed of three phases and the [Formula: see text]O kinetics are delayed in patients with heart failure (HF). This study aimed to investigate the kinetics of the cardiorespiratory response during and after the 6MWT according to exercise capacity.

Physical fitness of patients with a lower limb amputation predicts their walking ability and may be improved by physical exercise and training. A maximal exercise test is recommended prior to training in order to determine cardiovascular risks and design exercise programs. A potentially suitable ergometer for maximal exercise testing in patients with a lower limb amputation is the combined arm-leg (Cruiser) ergometer. The aim of this study was to determine feasibility, safety, and reliability of (sub)maxima...

Usefulness of six-minute walk test in systemic sclerosis.

The 6-minute walk test (6MWT) is a standardised, feasible and reliable measure of sub-maximal exercise capacity that has never been fully validated in systemic sclerosis (SSc). A variety of data suggest that many non-pulmonary aspects of SSc contribute to the test results, thus blunting the ability of the 6MWT to measure changes in lung function. Sources of variability are a training effect, technician experience, subject encouragement, medication, other activities on day of testing, deconditioning and the ...
