INTRODUCTION Common modalities of clinical exercise testing for outcome measurement after pulmonary rehabilitation (PR) include walk tests, progressive cycle ergometry, and cycle endurance testing. We hypothesized that patients' responses to PR, as measured by those 3 tests, are differentially correlated, and we designed a study to investigate the tests' capacity to detect changes after PR. M...

background:  the purpose of the present study was to examine whether a first bout of exhaustive exercise can change inflammo-endocrine responses to second subsequent similar exercise on the same day.  cortisol, tnf-α, and adenosin deaminas enzyme (ada) were assessed during a progressive endurance protocol. methods: eight well trained endurance runners (aged 23.13±3.39 years; weight, 66.21±9.47 ...

Twenty-eight healthy women (ages 27.2 +/- 6.4 yr) with widely varying fitness levels [maximal O2 consumption (VO2 max), 31-70 ml . kg-1 . min-1] first completed a progressive incremental treadmill test to VO2 max (total duration, 13.3 +/- 1.4 min; 97 +/- 37 s at maximal workload), rested for 20 min, and then completed a constant-load treadmill test at maximal workload (total duration, 143 +/- 3...

The slope of the curve relating integrated electromyographic activity of masseter muscle to biting force, the latency of the jaw-jerk reflex, and masticatory performance wee estimated in patients with Duchenne type of progressive muscular dystrophy before and during therapeutic exercise of the somatogenc system. The slope and latency were slightly decreased, and masticatory performance was incr...

After myocardial infarction (MI), there is progressive left ventricular (LV) remodeling and impaired exercise capacity. We tested the hypothesis that LV remodeling results in structural and functional changes that determine exercise impairment post-MI. Rats underwent coronary artery ligation (n = 12) or sham (n = 11) surgery followed by serial exercise tests and echocardiography for 16 wk post-...

BACKGROUND A study was carried out to determine whether rating of dyspnoea by means of a visual analogue scale during a progressive exercise test is affected by the subject's awareness of the progressive nature of the protocol. METHODS Nineteen patients with chronic obstructive lung disease (FEV1 mean (SE) 1.06 (0.07) 1) were studied. A preliminary incremental test was carried out with a work...

The present study examined the effects of progressive exercise (pyramidal) short-term program on plasma fibrinogen, lipid profile and blood viscosity in untrained young men. Changes and imbalances in homeostasis lead to cause of heart attacks. There is conflicting information about the effect of exercise on these factors. 19 young healthy untrained men were randomly assigned to the exercise gro...
