Abstract

Objectives: To systematically review and analyse studies of high amounts of physical activity and mortality risk in the general population. Eligibility criteria: Inclusion criteria related to follow-up (minimum 2 years), outcome (mortality from all causes, cancer, cardiovascular disease (CVD) or coronary heart disease), exposure (eg, a category of >1000 metabolic equivalent of task (MET) min/week), study design (prospective cohort, nested case control or case-cohort) and reports of cases and person years of exposure categories. Information sources: Systematic searches were conducted in Embase and Pubmed from database inception to 2 March 2019. Risk of bias: The quality of the studies was assessed with the Newcastle–Ottawa scale. Included studies: From 31 368 studies identified, 48 were included. Two authors independently extracted outcome estimates and assessed study quality. Synthesis of results: We estimated hazard ratios (HRs) using random effect restricted cubic spline dose–response meta-analyses. Compared with the recommended level of physical activity (750 MET min/week), mortality risk was lower at physical activity levels exceeding the recommendations, at least until 5000 MET min/week for all cause mortality (HR=0.86, 95% CI 0.78 to 0.94) and for CVD mortality (HR=0.73, 95% CI 0.56 to 0.95). Strengths and limitations of evidence: The strengths of this study include the detailed dose–response analyses, inclusion of 48 studies and examination of sources of heterogeneity. The limitations include the observational nature of the included studies and the inaccurate estimations of amount of physical activity. Interpretation: Compared with the recommended level, mortality risk was lower at physical activity levels well above the recommended target range. Further, there was no threshold beyond which lifespan was compromised. Registration: PROSPERO CRD42017055727.

  • Physical activity is inversely correlated with adverse cardiovascular outcomes and all-cause mortality.

    “Physical activity is inversely correlated to adverse cardiovascular outcomes5 and all-cause mortality and is recommended by the AHA as one of the ‘Life’s Simple 7’ lifestyle recommendations to promote heart health6.”
  • Wearable-measured physical activity has an inverse dose-dependent relationship with all-cause mortality.

    “Several studies have shown wearable-measured physical activity to have an inverse dose-dependent relationship with all-cause mortality5,34–38.”
  • Exposure to very high levels of leisure-time moderate-to-vigorous physical activity does not seem to increase the risk of cardiovascular disease or related events, at least in previously healthy adults.

    “exposure to very high levels of leisure-time MVPA does not seem to increase the risk of CVD or related events, at least in previously healthy adults.26”
  • Moderate-to-vigorous physical activity levels exceeding 5-7 times international recommendations, 5000 MET-minutes per week, are associated with lower cardiovascular disease mortality risk, about 27% lower, than adherence to current recommendations of 750 MET-minutes per week, with no apparent upper threshold.

    “MVPA levels exceeding 5-7 times international recommendations (5000 MET-min/week) were associated with a lower (-27%) CVD mortality risk than adherence to current recommendations (750 MET-min/week), with no apparent upper MVPA-threshold for this association.26”

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.
