Eleven male triathletes were studied to determine the relationships between selected metabolic measurements and triathlon performance. Measurements were made for oxygen consumption (V02), pulmonary ventilation (Ve) and heart rate (HR) during submaximal and maximal 400-yd freestyle swimming (FS), cycle ergometry (CE) and treadmill running (TR). Submaximal workloads were 1 m/sec for swimming, 200 watts for cycling and 7.5 mph for running. The mean (1/min) was significantly (P<0.05) lower during 1/min) than CE (4.68 1/sin) or TR (4.81 1/min). cycling and running performance times during the (1.2 mile swim, 56 mile cycle, 13.1 mile run) were to have a low relationship to V0z max (ml/kg/min) -0.32 and -0.55, respectively. The V0z max when expressed as 1/min was found to significantly (P<0.05) related to cycling time (r=-0.70). However, at a selected workload the %VO2 max was found to be highly related to swimming (0.91), cycling (0.78) and running (0.86) performance times. Maximal HR (bts/min) was also observed to be significantly (P<0.05) lower during FS (163) than CE (176) or TR (183). Running and cycling times in the triathlon were highly correlated (P<0.05) to overall triathlon performance times, 0.97 and 0.81, respectively, whereas swimming was found to be less a contributor to the athlete's final time, r=0.30. This study suggests that economy of effort is of greater importance to a triathlete's performance than their maximal oxygen uptake.
