Abstract: Previous endurance exercise studies suggest that a high-intensity low-volume taper period improves performance over a low-intensity taper period. However, few, if any, studies have examined different exercise intensities in the two days preceding a race, a period often manipulated during training. This study was conducted to compare performance in a simulated 40km cycling time trial (TT) 24hr after a high-intensity interval – low volume cycling session (HII), commonly described as an “openers,” or a low-intensity effort session (LIE). Eight subjects completed two simulated 40km time trials following a familiarization 40km TT (FAM). Performance trials, HII and LIE, were completed in a random crossover repeated measures design. Time to complete the TT, average power, VO2, respiratory exchange ratio (RER), and rating of perceived exertion (RPE) were measured. Neither time to completion nor average power differed between HII and LIE trials. Time taken to reach each 5km interval over the 40km distance did not differ between trials. The pattern of change in VO2, RER, and RPE did not differ between trials. Despite previous reports that high-intensity low-volume taper paradigms improve performance over a low-intensity taper no improvement was found in trained cyclists during 40km time trials completed 24hr after HII and LIE sessions.
