Subject: Physical Activity, All-Cause and Cardiovascular Mortality, and Cardiovascular Disease: A Systematic Review and Meta-Analysis of Multiple Health Outcomes
What this means
Any amount of moderate to vigorous activity was linked to lower death rates and less heart disease than none. Meeting the 2008 guidelines reached about 75% of the largest measured difference.

What does this rating mean?
Multiple consistent meta-analyses or a position stand. Sufficient basis for a fixed choice in the coaching.
Findings
An umbrella review of systematic reviews, meta-analyses and pooled analyses (2006 to March 2018) found that moderate-to-vigorous physical activity is associated with lower all-cause mortality, lower cardiovascular mortality and less cardiovascular disease. Benefits begin at about one third of guideline amounts; meeting the guidelines achieves about 75% of the maximal benefit. Activity beyond the guidelines adds further but progressively smaller gains.
Who this applies to
Adults, mainly from the US population, with activity levels as reported by the participants themselves.
Size of the research
Review of existing reviews and pooled analyses published from 2006 to March 2018.
What to keep in mind
These are associations, and activity was mostly self-reported. Above the guideline level, extra activity was linked to ever smaller additional differences.
Practical conclusion for REZA
Supports that every step towards the activity guidelines counts, including for people who are currently inactive. This review says nothing about resistance training specifically; other sources in the library cover that.
