The Effect of Exercise Training Intensity on VO2max in Healthy Adults: An Overview of Systematic Reviews and Meta-Analyses

This study aimed to evaluate systematic reviews and meta-analyses that have examined the effect of exercise training on VO2max in healthy individuals at different intensities. Five databases were searched: EBSCOhost, MEDLINE/PubMed, SPORTDiscus, Web Science, Google Scholar. Eligibility criteria for selecting included adults lower intensity (LIT) and/or high (HIT) VO2max. Eleven met eligibility criteria. All moderate-to-very strong methodological quality. The reported data from 179 primary studies with an average 23 ± 10 per review. this overview showed robustly increased all Three compared LIT versus HIT protocols small/moderate beneficial effects over LIT; however, appear be moderated by variables other than (e.g., impulse, interval length, volume, duration) participants’ baseline characteristics age fitness levels). Overall, evidence suggests apparent differences between either small, trivial, or inconclusive, several considerations required standardise research designs draw definitive conclusions.
