The Claim
Moderate strength training (1–149 minutes per week) is associated with a 26% lower risk of cardiovascular disease mortality in older women, independent of aerobic activity, and there is no significant association between moderate strength training and cancer mortality in older women.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Older women who do moderate strength training for 1 to 149 minutes per week have a 26% lower risk of dying from cardiovascular disease compared to those who do not, regardless of aerobic exercise. There is no measurable difference in cancer death rates based on this level of strength training.
See the scientific wording
Moderate strength training (1–149 min/wk) is associated with a 26% lower risk of cardiovascular disease mortality in older women, independent of aerobic activity, while no significant association was found for cancer mortality.
Lifting weights for a moderate amount of time builds muscle, which helps the body use sugar more efficiently and lowers harmful fats and inflammation in the blood. This reduces pressure on the heart and blood vessels. Doing too much weightlifting, however, causes extreme spikes in blood pressure and stress hormones that stiffen arteries and raise the risk of heart problems.
What the research says
1 studyOlder women who lifted weights 1 to 149 minutes a week were less likely to die from heart disease, even if they didn’t do other exercise. But lifting more than that didn’t help, and it didn’t change their risk of dying from cancer.
