Is Maximal Lactate Accumulation Rate Promising for Improving 5000-m Prediction in Running?

Endurance running performance can be predicted by maximal oxygen uptake (V̇Omax), the fractional utilisation of oxygen uptake (%V̇Omax) and running economy at lactate threshold (RE). This study aims to assess maximal lactate accumulation rate (ċLa) in terms of improving running performance prediction in trained athletes. Forty-four competitive female and male runners/triathletes performed an incremental step test, a 100-m sprint test and a ramp test to determine their metabolic profile.
