Abstract des Autors
This study assessed the influence of pedaling rate in bicycle exercise testing on perfusion of upper thigh and lower leg muscles, on blood lactate concentration, and on heart rate at subjective exhaustion. We examined 41 patients (54 +/- 9 years, 169 +/- 8 cm, 72.7 +/- 13.7 kg) without evidence of peripheral or coronary artery disease. Starting with 50 W, workload was increased by 25 W every two minutes until exhaustion. The pedaling rate of 40, 60, or 80 revolutions per minute was chosen randomly. Injection of 100 MBq 201-thallium was performed within the last 30 sec of exercise. 201-thallium is actively taken up by myocytes in proportion to blood flow. The three groups with different pedaling rates showed no difference with regard to the parameters examined. In bicycle exercise testing blood lactate concentration, heart rate, and perfusion of leg muscles are not influenced by small changes in pedalling rate in the exhausted clinical patient. Verf.-Referat
