Abstract

BACKGROUND: No conclusions have been drawn regarding the relative attrition and adherence rates associated with sustained vs. intermittent exercise programs. PURPOSE: The study aims to systematically examine randomized controlled exercise intervention trials that report attrition and/or adherence rates to sustained vs. intermittent aerobic exercise programs. METHODS: A comprehensive literature search was conducted, and references from qualifying articles were searched for additional papers. RESULTS: Fourteen articles met inclusion criteria, capturing 783 (76% female) enrolled and 599 (74% female) retained participants (mean age = 42.3 ± 6.6 years). Study durations ranged from 8 weeks to 18 months (mean duration = 22.7 ± 21.9 weeks). Although results varied, no consistent differences in attrition or adherence rates between sustained and intermittent exercise protocols were revealed. CONCLUSIONS: Given the universally low rate of regular exercise participation and the ongoing problem of adherence to exercise protocols, the field may benefit from randomized controlled trials examining sustained vs. intermittent exercise programs in greater depth.

  • Exercise adherence is challenging; fewer than half of participants enrolled in structured programs continue to meet recommended physical activity targets beyond six months.

    “fewer than half of participants enrolled in structured programs continue to meet recommended physical activity targets beyond six months”

    From Weight maintenance after discontinuation of GLP-1 therapies (2026) · cites this paper as [83]

    The Introduction (page unavailable) reports a commonly cited estimate that 50% of people who start an exercise program drop out within six months, and says adherence is often low in intervention studies. It does not establish that fewer than half of structured-program participants continue to meet recommended physical activity targets beyond six months; dropping out and meeting activity targets are different measures.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
