This study examined the reproducibility of a simulated 40 km time trial (40TT) repeated on 3 separate occasions prior to pre‐season training. On days 1 (TT1), 3 (TT2) and 5 (TT3), 9 experienced cyclists (X± SD VO2max: 4.27 ± 0.28 L · min−1) performed the 40TT using their own bicycles mounted on wind‐loaded rollers which were mechanically connected to an odometer to record distance cycled. Exercise time and selected metabolic and respiratory measures were recorded at 10 km intervals. The results showed that the mean VO2 (3.57 ±0.50, 3.61 ±0.38, 3.59±0.38L· min−1), cycling velocity (557.4±42.7, 568.3±46.1, 579.8±36.7 m·min−1) and time (min: s; 72:00 ± 5 :20, 70: 50 ± 5:16, 69: 57 ± 4:49) were not different (p < 0.05) between TT1, TT2, TT3, respectively. However, coefficient of variation for time was 3.7%. 40TT cycling intensity was performed at 7% above ventilation threshold of each individual. BLa (mM) was different at only the 10 km interval between TT1 (6.2 ±1.98) vs. TT2 (4.3 ±1.41) and TT3 (4.5 ± 1.63)... |
