Abstract

The objective of this study was to analyze, in triathletes, the possible influence of the exercise mode (running × cycling) on time to exhaustion (TTE) and oxygen uptake (VO2) response during exercise performed at the intensity associated with the achievement of maximal oxygen uptake (IVO2max). Eleven male triathletes (21.8 ± 3.8 yr) performed the following tests on different days on a motorized treadmill and on a cycle ergometer: 1) incremental tests in order to determine VO2max and IVO2max and, 2) constant work rate tests to exhaustion at IVO2max to determine TTE and to describe VO2 response (time to achieve VO2max - TAVO2max, and time maintained at VO2max - TMV·O2max). No differences were found in VO2max, TTE and TMVO2max obtained on the treadmill tests (63.7 ± 4.7 ml/kg/min; 324.6 ± 109.1s; 178.9 ± 93.6s) and cycle ergometer tests (61.4 ± 4.5 ml/kg/min; 390.4 ± 114.4s; 213.5 ± 102.4s). However, TAVO2max was influenced by exercise mode (145.7 ± 25.3 vs. 176.8 ± 20.1s; in treadmill and cycle ergometer, respectively; p=0.006). It is concluded that exercise modality affects the TAVO2max, without influencing TTE and TMVO2max during exercise at IVO2max in triathletes. Verf.-Referat
