The purpose of this study was to determine whether a CL cycling session or a VL cycling session stimulated different physiological and psychological responses leading to better performance on a subsequent 10-kilometer time trial. Recreationally trained male cyclists (n=8, age 32 +/- 5.3 y, mass 75.7 +/- 10.9 kg, body fat 13.4 +/- 5.6%, VO2 peak 4.6 +/- 0.6 L x min-1) completed two experimental trials. During the VL trial, participants alternated between 3 minutes at 45% of maximal aerobic power and 3 minutes at 85% until completion of the 63 minute trial. During the CL trial, participants cycled at a constant 65% of aerobic power for 63 minutes. Intensities were set to hold the total amount of work constant and trials were followed by a self-paced 10 km time trial. For the VL and CL experimental trials, there was no significant difference in average VO 2 (p = 0.26) and no difference in HR between VL and CL trials (p = 0.51). There was a trend that did not reach statistical significance in blood Lactate between VL and CL trials (p = 0.06). RPE and attentional focus were higher in the VL trial than the CL trial (p < 0.01 and p = 0.02, respectively). Ten kilometer time trial performance times following the experimental trials were not different between VL (16.97 + 2.07 min) and CL (16.81 + 1.47 min, p = 0.62). There was no difference in VO2(p = 0.43), HR (p = 0.64), or blood lactate (p = 0.52) between VL and CL performance trials. There was no difference for RPE (p = 0.22), Feeling Scale (p = 0.63), and Attentional Focus (p = 0.32) between VL and CL performance trials. These data indicate that despite differences in perception of VL and CL cycling, there are no differential effects on subsequent performance, physiology, or perception.
