Throughout the sprints, velocity was measured using a laser velocity guard (LAVEG) to estimate maximal velocity (vmax) and power (Pmax). The talac was calculated as the time when power decreased by 3.5% (tpmax-3.5%) and interpolated based on the sprint time (tinter,LB and tinter,SW). Reliability was assessed using intraclass correlation coefficient (ICC), typical error (TE) and smallest worthwhile change (SWC).ResultsAfter initial familiarisation, t100, tinter, vmax, Pmax and {\.V}Lamax attained excellent reliability (ICC ≥ 0.90), whereas tpmax−3.5% attained moderate reliability (ICC = 0.518). The reliability of {\.V}Lamax was higher when tinter,LB or tinter,SW were used (ICC = 0.960) compared to using tpmax−3.5% (ICC = 0.928).
