The effects of manipulation of Frequency, Intensity, Time, and Type (FITT) on exercise adherence: A meta‐analysis

This meta-analysis quantified the effect of FITT (frequency, intensity, time, and type) manipulation on exercise adherence. Databases were searched from inception to 09-2018. Manipulation of intensity resulted in a moderate, significant decrease in adherence (MD: −3.3, 95% CI: −6.1 to −0.5), and for the remaining FITT components, there were trivial-small, non-significant effects. When stratified by chronic disease status, for populations with...
