Abstract
Introduction: In recent years, maximal lactate accumulation rate (VLamax) has received increasing attention as an estimator of maximal glycolytic power. The VLamax could enhance physiological profiling by aiding in athlete assessment, training prescription, and talent identification. Objective: This systematic review aims to synthesize and analyse studies that have assessed the reliability of the VLamax as a representative parameter of maximal glycolytic power in healthy adult subjects. Methodology: The proposed PICO question was: Is VLamax a reliable metric for estimating maximal glycolytic power in healthy adults? Systematic literature searches on PubMed, Google Scholar, Scopus, SPORTDiscus and Web of Science were conducted. Five articles were included. The quality of the included articles was assessed using a modified Downs and Black Checklist. Results: All articles were considered to be high quality (76,9-84,6%). The intraclass correlation coefficient (ICC) of VLamax was 0.66-0.96. Discussion: The reliability of VLamax is influenced by factors that affect lactate accumulation and the estimation of alactic time. VLamax strongly correlates with the power or speed of maximal efforts lasting 20-31 seconds, aligning with the glycolytic energy system's peak contribution range. Conclusions: This systematic review shows that the VLamax estimates maximal glycolytic power with moderate to excellent reliability, although further research is needed to better understand this metric: the most appropriate test to determine it in a practical way, its relationship with other markers of anaerobic performance, its response to certain training methods and its influence on maximal metabolic steady state, among others.
