Abstract
Over the past two decades, scientists have attempted to evaluate whether the point of
maximal fat oxidation (FATmax) and the aerobic threshold (AerT) are connected. The existence of such
a relationship would allow a more tailored training approach for athletes while improving the efficacy
of individualized exercise prescriptions when treating numerous health-related issues. However,
studies have reported conflicting results, and this issue remains unresolved. This systematic review
and meta-analysis aimed: (i) to examine the strength of the association between FATmax and AerT by
using the effect size (ES) of correlation coefficient (r) and standardized mean difference (SMD); (ii) to
identify potential moderators and their influence on ES variability. This study was registered with
PROSPERO (CRD42021239351) and ClinicalTrials (NCT03789045). PubMed and Google Scholar were
searched and fourteen articles, consisting of overall 35 ES for r and 26 ES for SMD were included.
Obtained ESs were analyzed using a multilevel random-effects meta-analysis. Our results support
the presence of a significant association between FATmax and AerT exercise intensities. In conclusion,
due to the large ES variance caused by clinical and methodological differences among the studies, we
recommend that future studies follow strict standardization of data collection and analysis of FATmax
and AerT-related outcomes.
