- Abstract
Introduction: This work analyzes and describes the behavior of the respiratory system and the system of oxygen contribution during a moderate intensity test accomplished in a cycloergometer. Materials and Methods: A sample composed of 10 individuals (age: 17.94±2.51 years old; weight: 69.08±7.32kg; height: 1.73±0.05m), with 4.55±0.72 years of experience in cycling. All of them were submitted to two tests. The fi rst one, an incremental test until exhaustion (Δ of 5W each 12s, starting from 100W), which served to determine the VO2max, the ventilatory threshold and the workload for the test of stable load in moderate intensity (TSM). In the TSM they worked during 30s with an individually determined load (249.50±18.02W a 3.64±0.38W.kg-1). Results: The load in the TSM was 58.82±2.48% of the maximum load reached in the incremental test and 67.60±5.46% of the load reached in the anaerobic threshold in the same test. Discussion: In our study, the VO2 increased in 8.8ml.kg-1.min-1 in the beginning of the test, until reaching 90.17±2.9% in the beginning of phase 3 or stable state (5t). From this point on, the studied individuals showed a smooth and progressive increase of VO2, until, approximately, 12min of exercise, when they stabilized the response until the end of the test.
