abstract = {Regular exercise at the intensity matching maximal fat oxidation (FATmax) has been proposed
as a key element in both athletes and clinical populations when aiming to enhance the body’s
ability to oxidize fat. In order to allow a more standardized and tailored training approach, the
connection between FATmax and the individual aerobic thresholds (AerT) has been examined. Although
recent findings strongly suggest that a relationship exists between these two intensities,
correlation alone is not sufficient to confirm that the intensities necessarily coincide and that the error
between the two measures is small. Thus, this systematic review and meta-analysis aim to examine
the agreement levels between the exercise intensities matching FATmax and AerT by pooling limits of
agreement in a function of three parameters: (i) the average difference, (ii) the average within-study
variation, and (iii) the variation in bias across studies, and to examine the influence of clinical and
methodological inter- and intra-study differences on agreement levels. This study was registered
with PROSPERO (CRD42021239351) and ClinicalTrials (NCT03789045). PubMed and Google Scholar
were searched for studies examining FATmax and AerT connection. Overall, 12 studies with forty-five
effect sizes and a total of 774 subjects fulfilled the inclusion criteria. The ROBIS tool for risk of bias
assessment was used to determine the quality of included studies. In conclusion, the overall 95%
limits of agreement of the differences between FATmax and AerT exercise intensities were larger
than the a priori determined acceptable agreement due to the large variance caused by clinical and
methodological differences among the studies. Therefore, we recommend that future studies follow a
strict standardization of data collection and analysis of FATmax- and AerT-related outcomes.},
