The purpose of this study was to determine the influence of starting strategy on time trial performance in the heat. Eleven endurance trained male cyclists (30±5 years. 79.5±4.6kg. O2 58.5±5.Oml.kg1 min’) performed four 20-km time trials in the heat (32.7 ± 0.7°C and 55% rela tive humidity). The first time trial was completed at a self-selected pace (SPiT). During the follow- ¡ng time trials, subjects performed the initial 2.5-km at power outputs 10% above (10% AU), 10% below(10% BU) or equal (FIT) to that of the average power during the initial 2.5-km of the self-selected trial; the remaining 17.5-km was self-paced. Throughout each time trial, power output, rectal temperature, skin temperature, heat storage, pain intensity and thermal sensation were taken. Despite significantly (P<0.05) greater power outputs for 10% BU (273 ±45W) compared with the EU (267 ± 48W) and 10% AU (265±41W) during the final 17.5-km, overall 20km performance time was not significantly different amongst trials. There were no differences in any of the other measured variables between trials. These data show that varying starting power by ±10% did not affect 20km time trial performance in the heat.
