A group of 26 male long-distance runners performed 3 cycle ergometer tests of progressively increasing intensity up to exhaustion. The tests were performed on 3 different days. The workload increased as follows: 30 Watts every 3 min (test I), 10 Watts every min (test II), and 30 Watts every min (test III). Ventilatory and gas exchange measurements were averaged every 30 sec during each test. The heart rate (HR) was monitored continuously by ECG. In each test the anaerobic threshold (AT) was determined using ventilatory and gas exchange indices (VE, VCO2, VE/VO2). The work load on exhaustion and power at AT were the same comparing test I with test II, but these values were significantly higher in the 30 Watts/1 minute test. Conversely, maximal oxygen uptake (VO2 max) and the VO2 observed at anaerobic threshold were comparable in the 3 protocols. The slopes of VO2, VCO2, VE and HR against the work load (Watts) were identical in test I and II, but were slower in test III. However, no differences in the ventilatory and heart rate patterns versus oxygen uptake were observed comparing the three exercise tests. These results suggest a good comparability between the 30 Watts/3 min test and the 10 Watt/1 min protocol. Furthermore, for workloads below AT, a steady state was attained at the 3rd minute of each phase during test I, while oxygen uptake and other cardio-respiratory variables were underestimated during the protocol in which phases of 30 Watts were maintained only for 1 minute.(ABSTRACT TRUNCATED AT 250 WORDS)
