This exercise habit may slash dementia risk and help you live longer, study finds

People who incorporate strength training into their weekly routines may be more likely to live longer, according to a new study.

Researchers from the Harvard T.H. Chan School of Public Health analyzed data from 147,374 adults and found that people who engaged in moderate amounts of resistance training had a lower risk of dying from several major causes, including heart disease and neurological disease.

The findings were published in the British Journal of Sports Medicine.

People who performed between 90 and 119 minutes of resistance training per week had a 13% lower risk of death from any cause compared to those who did no strength training.

The same group also experienced a 19% lower risk of death from cardiovascular disease and a 27% lower risk of death from neurological diseases, most of which were related to dementia.

Researchers found that the greatest benefit occurred when resistance training was combined with aerobic exercise.

Adults who regularly participated in both forms of exercise had up to a 45% lower risk of death than those who did little aerobic activity and no resistance training.

However, more exercise was not necessarily better.

The study found no additional reduction in mortality risk beyond about 120 minutes of resistance training per week.

The research followed participants for up to 30 years and repeatedly tracked their exercise habits over time, giving researchers a more complete picture of long-term behavior.

Josephine Hunt, an educational leader, former group fitness instructor and founder of The Resilience Revolution based in New Jersey, who was not involved in the study, said the findings support a growing body of research linking strength training to healthy aging.

“The conversation about longevity often focuses on living longer, but I believe the more important goal is maintaining the strength, mobility, independence, and vitality to fully participate in life as we age,” Hunt told Fox News Digital.

Hunt said resistance training helps preserve muscle mass and bone density, improves balance and supports overall physical function as people get older.

For women, she noted, strength training becomes especially important after menopause, when muscle mass and bone density can decline more rapidly.

“Resistance training is not about bodybuilding, appearance, or achieving a certain physique,” Hunt said.

Experts say longevity is not just about living longer, but staying strong, mobile and independent with age. (iStock)

“It is about preserving the ability to live life on your own terms.”

She added that strength training can help people remain independent, recover from illness or injury, travel more easily and stay active later in life.

Researchers noted that the study has limitations.

While the findings suggest a connection between strength training and a lower risk of death, the study cannot prove that lifting weights was the reason participants lived longer.

The study also relied on self-reported exercise habits and primarily included white, middle-aged and older health professionals, which may limit how broadly the findings apply to the general population.

These leafy greens could help protect your lungs, study suggests

Scientists have linked eating leafy green vegetables such as spinach, kale and broccoli to better lung health.

There are two primary forms of vitamin K found in foods. The primary kind is vitamin K1, found mainly in vegetables, which plays a major role in the body’s blood-clotting process.

Vitamin K2 is found in fermented foods, certain dairy products, eggs and meats and helps regulate calcium in the body and supports bone health.

Researchers at Australia’s Edith Cowan University examined whether dietary intake of vitamins K1 and K2 was associated with chronic obstructive pulmonary disease (COPD), asthma and lung function.

“Chronic respiratory diseases, including chronic obstructive pulmonary disease (COPD) and asthma, are among the most prevalent noncommunicable diseases worldwide and were the third leading cause of death in 2019, accounting for 4 million deaths and affecting 454.6 million individuals globally,” the scientists reported in the introduction to their study, published in The American Journal of Clinical Nutrition.

“Although asthma and COPD can be managed with available treatments, neither condition is curable, underscoring the need for effective prevention strategies,” they added.

The leading cause of COPD is smoking, the Mayo Clinic reported. Exposure to other irritants, such as dust, chemicals and pollution, can also cause it.

The researchers analyzed data from 179,062 participants over a 10-and-a-half-year period and concluded that, “Higher dietary vitamin K1 intake was associated with better lung function and a lower rate of COPD.”

Participants who consumed the most vitamin K1 had a 16% lower likelihood of COPD, the researchers observed. The effects were more pronounced in smokers and participants with high-risk occupations.

Consumption of vitamin K2 did not result in lower COPD rates.

“No association was observed for vitamin K1 or vitamin K2 intakes and asthma,” the researchers also wrote.

Associate Professor Marc Sim, who was involved in the study, said that it’s likely Vitamin K activates a protein that may help keep lung tissue flexible and prevent damage.

Because the study was observational, it cannot prove that vitamin K1 directly reduces COPD risk, only that higher intake was associated with better lung health.

Just one extra serving of leafy greens “is an achievable way to boost your vitamin K1 intake,” said Chengfeng Li, one of the study’s researchers.

Other foods rich in vitamin K1 include collard greens, Swiss chard, Brussels sprouts and turnip greens.
