Both time-to-exhaustion (TTE) and time-trial (TT) exercise tests are commonly used to assess performance, but no study has directly examined the reliability of comparable in same subjects. Purpose: To evaluate TTE TT treadmill running high moderately intensity endurance-trained male distance runners, validate Hinckson Hopkins prediction methods using log-log modeling from results. Methods: After familiarization tests, eight runners performed, a randomized, counterbalanced order, trials consisting two 5-km 1500-m TT, four run at speed equivalent average attained during both distances. Results: Typical error estimate (TEE) expressed as coefficient variation for TTE, were 2.0, 15.1, 3.3, 13.2%, respectively. The standard predicted results was 0.67%, versus criterion this method revealed TEE values 1.6% 2.5% Conclusion: variability significantly less than similar protocols. Despite greater test reliably actual performance.
