The purpose of this meta-analysis was to examine the effect of acute aerobic exercise on self-reported positive-activated affect (PAA). Samples from 158 studies from 1979 to 2005 were included yielding 450 independent effect sizes (ESs) and a sample size of 13,101.

Studies were coded for moderators related to assessment time, exercise variables such as intensity, duration, and dose (combination of intensity and duration), and design characteristics. The analysis considered multiple measures of affect and corrected for statistical artifacts using Hunter and Schmidt [(1990). Methods of meta-analysis: Correcting error and bias in research findings. Newbury Park: Sage; (2004). Methods of meta-analysis: Correcting error and bias in research findings (2nd ed.). Thousand Oaks: Sage] meta-analytic methods.
