Many exercise protocols are in use in clinical cardiology, but no single test is applicable to the wide range of patients' exercise capacity. A new protocol was devised that starts at a low workload and increases by 15% of the previous workload every minute. This is the first protocol to be based on exponential rather than linear increments in workload. The new protocol (standardised exponentia...

The purpose of this study was to determine the prognostic value of a normal 201Tl scan in patients with a positive treadmill exercise stress test. We analyzed retrospectively 85 consecutive patients with a positive treadmill exercise test and normal Tl201 scan who were studied for the diagnosis of coronary artery disease from January 1996 to December 2000. The pretest probability of coronary ar...

PURPOSE This study aimed to investigate the validity and reproducibility of a new treadmill protocol in healthy children and adolescents: the Fitkids Treadmill Test (FTT). METHODS Sixty-eight healthy children and adolescents (6-18 yr) were randomly divided into a validity group (14 boys and 20 girls; mean ± SD age, 12.9 ± 3.6 yr) that performed the FTT and Bruce protocol, both with respirator...

BACKGROUND Comparative cardiovascular responses to treadmill and bicycle ergometer (bike) exercise tests in hypertensive Nigerians are not known. This study compared cardiovascular responses to the two modes of exercise testing in hypertensives using maximal exercise protocols. METHODS One hundred and ten male subjects with mild-to-moderate hypertension underwent maximal treadmill and bike te...

BACKGROUND Lumbar spinal stenosis (LSS) is defined as narrowing of the spinal canal. LSS is commonly treated conservatively, primarily with flexion-based exercises. We present a patient diagnosed with LSS, refractory to a flexion-based protocol who ultimately responded to an extension-based protocol following establishment of directional preference with three-step treadmill testing. DESCRIPTI...

The purpose of this study was to determine differences in VO2max and metabolic variables between treadmill running and treadmill skating. This study also examined VO2max responses during a continuous skating treadmill protocol and a discontinuous skating treadmill protocol. Sixteen male high school hockey players, who had a mean age of 16 +/- 1 years and were of an above-average fitness level, ...

STUDY OBJECTIVE To test the performance of a tool designed to estimate functional capacity in order to select a bicycle ramp protocol yielding a test duration from 8 to 12 min in healthy individuals, and to assess differences in exercise responses between bicycle and treadmill tests. PARTICIPANTS AND MEASURES Forty-one healthy and physically active volunteers (10 women; median age, 37 years; ...

The pathophysiology of primary benign exertional headache (EH) is not still clearly defined. Some researchers have suggested an impaired vascular response as the etiology of this disorder. In this study we investigated whether there are any differences in blood pressure (BP) and heart rate (HR) of the subjects in course of the static and dynamic exercises and the treadmill stress test between t...
