Authors' conclusion

In this large prospective study of U.S. women, consistent resistance training, especially when integrated with recommended levels of aerobic activity and reduced sedentary television viewing, was associated with a substantially lower risk of major CVD, particularly MI.

Study context

Population
Women in the Nurses' Health Study (2002–2020) and Nurses' Health Study II (2003–2017)5,459 major cardiovascular disease (CVD) events
Participants
117,025 women
Exposure
Resistance training ≥2 h/wk vs no resistance training
Outcome
Incident major CVD (nonfatal or fatal myocardial infarction (MI), stroke, CABG or PCI)
Follow-up
Mean 14.5 years

Main finding

MI (≥2 h/wk vs none)0.56 (0.41–0.76)
Stroke (≥2 h/wk vs none)0.99 (0.80–1.23)

Major CVD by joint recommendations (aerobic ≥15 MET-h/wk, resistance training ≥1 h/wk, TV <2 h/d)

Met aerobic, resistance training and low sedentary TV viewing recommendations: HR
0.60 (95% CI 0.53-0.69)
Met aerobic and low sedentary TV viewing recommendations but not resistance training: HR
0.73 (95% CI 0.67-0.80)

Consistency (≥75% of follow-up) and upper + lower limb training

Associated with stronger inverse associations
