New study links resistance training to lower cardiovascular risk in women

A new study published in JACC, analyzing data from 117,025 women in the Nurses' Health Study, suggests that resistance training may lower the risk of severe cardiovascular disease, particularly heart attacks. The research, led by Dr. Tianyue Zhang of the Harvard T.H. Chan School of Public Health, indicates that muscle-strengthening exercises provide additional benefits when combined with aerobic activity. Resistance training includes weightlifting, using elastic bands, gym machines, or bodyweight exercises. Current U.S. guidelines recommend at least two days of resistance training per week alongside 150 minutes of moderate to vigorous aerobic exercise. The findings emphasize that sedentary behavior, such as prolonged television viewing, acts as an independent risk factor for heart health. Researchers aimed to clarify the specific additional value of resistance training beyond standard aerobic activities. The study underscores the importance of diversifying physical activity strategies to prevent the leading global cause of mortality.
