Table 1 Intraclass correlation coefficients for relative reliability of sprint times during a repeated (9 × 30 s) figure-of-eight sprint test with varying rest periods with and without the first and last sprints.*†

From: Attentional and visual demands for sprint performance in non-fatigued and fatigued conditions: reliability of a repeated sprint test

   Base measurement Attention-demanding task Restricted vision
NFC First sprint included 0.77 (0.50 - 0.90) 0.78 (0.54 - 0.92) 0.85 (0.67 - 0.93)
  First sprint excluded 0.80 (0.60 - 0.92) 0.83 (0.61 - 0.93) 0.86 (0.67 - 0.94)
FC Last sprint included 0.90 (0.74 - 0.96) 0.82 (0.59 - 0.92) 0.68 (0.35 - 0.86)
  Last sprint excluded 0.94 (0.85 - 0.98) 0.85 (0.65 - 0.94) 0.75 (0.45 - 0.89)
  1. * NFC, non-fatigued condition; FC, fatigued condition.
