The purpose of this study was to investigate the effects of prior cycling on running economy (RE) during the running portion of a simulated Olympic distance triathlon. Six triathletes and one duathlete participated in four consecutive laboratory trials: (1) maximal treadmill tests, (2) independent 40km cycling trial (IC), (3) independent 10km treadmill running (IR) and (4) 40km cycling (TC) followed by a 10km treadmill run (TR). Pulmonary data were collected every minute using an automated breath-by-breath system and compared between the first and last ten minutes of each trial. The data showed a significant increase was seen in RE from IR (191.8±11.1 ml of O2 • min·1 • km·1, 196.4 ± 8.5 ml of O2 • min·1 • km·1) to TR (223.0 ± 4.6 ml of O2 • min·1 • km·1 , 219.4 ± 4.7 ml of O2 • min·1 • km·1). We concluded that prior cycling caused an increase in Ve, Ve/VO2, and Ve/VCO2 this in tum caused a decrease RE.
