Pumping iron may help you live longer – CSPI

We wanted to know if weightlifting alone—or in combination with aerobic exercise—influences one’s risk of early death,” says Jess Gorzelitz, assistant professor of health and human physiology at the University of Iowa, according to the Center for Science in the Public Interest (CSPI).


“So we asked a group of roughly 100,000 older adults about their lifestyle, and then we followed them for about 10 years.”
Those who hit the U.S. Physical Activity Guidelines for aerobic activity—150 minutes of moderate or 75 minutes of vigorous activity a week—were nearly a third less likely to die over those 10 years. That’s no surprise, since aerobic activity improves cardiovascular fitness and is linked to a lower risk of several cancers.

“But we also found that weightlifting, independent of aerobic activity, was linked to a 10 to 20 percent lower risk of dying,” says Gorzelitz.

Less than five hours’ sleep a night linked to higher risk of multiple diseases

Getting less than five hours of sleep in mid-to-late life could be linked to an increased risk of developing at least two chronic diseases, finds a new study led by University College London (UCL) researchers.

The research, published in PLOS Medicine, analysed the impact of sleep duration on the health of more than 7,000 men and women at the ages of 50, 60 and 70, from the Whitehall II cohort study.

Researchers examined the relationship between how long each participant slept for, mortality and whether they had been diagnosed with two or more chronic diseases (multimorbidity) — such as heart disease, cancer or diabetes — over the course of 25 years.

People who reported getting five hours of sleep or less at age 50 were 20% more likely to have been diagnosed with a chronic disease and 40% more likely to be diagnosed with two or more chronic diseases over 25 years, compared to people who slept for up to seven hours.

Deep dive on exercise and the heart – JACC

The Journal of the American College of Cardiology (JACC) has issued a four-part focus seminar series on sports cardiology and of the impact of physical activity, cardio-respiratory fitness and exercise training on the general U.S. population and professional athletes’ cardiovascular health.

“The field of sports cardiology is a well-established but still rapidly evolving sub-specialty,” said Jason C. Kovacic, professor at the Icahn School of Medicine at Mount Sinai and author of the accompanying introduction article to the focus seminar series. “Given the mounting interest in sports cardiology, its key relevance to all cardiovascular practitioners, and the knowledge explosion in this field, we felt it was particularly timely to pay special attention to this broad topic with a JACC Focus Seminar series.”
