Abstract: 
Many consider the Wingate Anaerobic Test (WAnT) as a reference standard assessment mode in the measurement of lower limb short-term power output. However the WAnT is criticised for having low ecological validity, in non-cycling tasks and is reliant on a predetermined applied force, which might not elicit the highest power output. A viable alternative to the WAnT is the Non-Motorised Treadmill (NMT) Test, which allows for power measurement in all-out intensity effort sprint-running. With the reliability of the NMT to elicit power in sedentary adults already established, the aim was to compare peak power (PP) and mean power (MP) derived from a 10-s sprint on the NMT to that derived from a 10-s WAnT, to establish concurrent validity. Materials and Methods: Twelve male [age 26.6 ± 2.4 years, body mass (BM)63.0± 7.2 kg] and 11 female (age 25.3±3.6 years, BM 51.0±4.0 kg) sedentary adults participated in the study. PP and MP in absolute, ratio-scaled and allometrically-scaled to BM were analysed. Ratio limits of agreement (LOA) was used to establish the agreement between PP and MP from the NMT and the WAnT.~: PP in absolute and ratio-scaled to BM from the NMT was between 1.04 and 1.12 times that ofPP from the WAnT in 95% ofthe attempts (PP: NMT, 647.1 ± 176.4Wvs WAnT,597.0± 146.0W). MP in absolute and ratio-scaled to BMfrom the NMT test was between 0.88 and 0.97 times of that from the WAnT (MP: NMT, 508.9 ± 130.7W vs WAnT, 548.7 ± l31.3W). Power produced on the NMT and the WAnT by sedentary adults shared moderate and acceptable levels of agreement. Conclusions: These results affirmed that the NMT could be considered as a viable alternative to the WAnT for the assessment ofPP and MP in allout intensity sprint-running lasting 10 s in sedentary adults.
