OBJECTIVE This study aims to construct quantile reference values for peak oxygen uptake (V̇O2peak) measured by cycle ergometry-based incremental cardiopulmonary exercise tests. DESIGN Cross-sectional study using quantile regressions to fit sex-specific and age-specific quantile curves. Exercise tests were conducted using cycle ergometry. Maximal effort in the exercise tests wass assumed when r...

BACKGROUND: Adiponectin, an adipose tissue protein, plays a crucial role in the development of metabolic syndrome and atherosclerosis. As potential therapeutic target, this adipokine can be considered context treatment strategies.
 AIM: The aim study was to assess correlation between changes plasma adiponectin concentration during coronary heart disease therapy effectiveness treatment, as ...

Abstract Purpose This study aimed to investigate the reliability of surface electromyography (EMG) assessed at seven muscles during three repeated 2000 m rowing ergometer sessions. Methods Twelve male well-trained rowers participated in a measures design, performing sessions interspersed by 3–7 days (S1, S2, S3). Surface electrodes were attached gastrocnemius, biceps femoris, gluteus maximus, e...

Forty-seven subjects over the age of 40 years, with atypical praecordial symptoms and a normal resting electrocardiogram, were evaluated for early detection of ischaemic heart disease using the single two-step exercise test, the multistage bicycle ergometric test, and continuous 24-hour ambulatory electrocardiographic monitoring. In 40 of the 47 subjects the results of both the ergometric test ...

With the use of three-dimensional whole body scanning technology, this study compared the 'traditional' anthropometric model [one-dimensional (1D) measurements] to a 'new' model [1D, two-dimensional (2D), and three-dimensional (3D) measurements] to determine: (1) which model predicted more of the variance in self-reported best 2000-m ergometry rowing performance; and (2) what were the best anth...

Rogan, Needham, and McDonald (1955) performed lung-function tests on patients suffering from Bechterew's disease; their studies did not, however, include measurements during exercise. Julian, Travis, and Bayles (1959) also performed lung-function tests at rest only, but they advocated investigations during strain. Renzetti, Nicholas, Dutton, and Jivoff (1960) mention the occurrence of hypervent...

In order to overcome cancer-related problems and to improve quality of life, an intensive multi-focus rehabilitation programme for cancer patients was developed. We hypothesised that this six-week intensive rehabilitation programme would result in physiological improvements and improvement in quality of life. Thirty-four patients with cancer-related physical and psychosocial problems were the s...
