Table 3. Power output (mean ± SD) (W) obtained during the short sprints performed after the incremental test for the oval Q-rings and the conventional rings (C-rings). Differences in power output between Q-ring and C-ring are expressed as a percentage (∆%).
Q-ring C-ring Difference (∆%)
  1st sprint 715 (74) 682 (100) 4.6
  2nd sprint 582 (47) 568 (62) 2. 4
  3rd sprint 526 (78) 499 (71) 5.1
  4th sprint 510 (84) 476 (74) 6.7
