Abstract

The purpose of this meta-analytical review was to synthesize the data and find a consensus within the literature as to how beta-blockers affect VO2 max in the healthy population. A thorough investigation of the literature was first performed, and a coding form developed to help select those articles with similar procedures that would be comparable to one another. This process resulted in the analysis of 10 research studies, in which the mean and standard deviation for an overall and for correlated non beta-blocker results, selective beta-blocker results, and non-selectivebeta blocker results were calculated.

The overall calculations showed little difference, but the results indicate 1 MET (3.5 ml.kg-1.min-1 ) average decrease from the non-medicated condition to the selective beta-blockers condition, and 1.25 MET (4.44 ml.kg-1.min-1) decrease from the non-medicated condition to the non-selective beta-blocker condition. These results were deemed not to have any practical significance according to ACSM exercise prescription guidelines. A practical difference of 2 METs is considered to be substantially important by researchers when calculating for an exercise prescription. Though there seemed to be agreement within the literature of the decrease in VO2 max, it is not considered to be a practical difference in the clinical setting.
