NOTE: Weighted mean effect size values (d+) are positive when the exercise intervention was successful in reducing CRF compared to standard care. MET values were provided to demonstrate the emerging patterns among theory, age, and intervention quality with increasing resistance exercise intensity, representing light (2.0 MET) and moderate (6.0 MET) intensity.

  • aLevels represent values at the extreme observations of each moderator and for other values of interest within that range.

  • bd+ and their 95% CI estimates statistically adjust for the presence of the moderators in the mixed-effects model, including the linear and quadratic trends for strength intensity, use of theory, age, and intervention quality, held constant at their means except for differences in strength intensity and the study dimension in question.
