Physical activity at work not as healthy as leisure exercise – Study

There were more than 7,900 major cardiovascular events, such as heart attacks and strokes, and about 9,850 deaths overall during an average of 10 years of follow-up. The more leisure-time physical activity a person reported, the lower their risk of dying or experiencing a heart attack, stroke or other cardiovascular event.

By contrast, folks who said they got most of their physical activity on the job were more likely to die or sustain a cardiovascular event than those people who reported less manual labor. The findings held even after the researchers controlled for other factors that affect heart and stroke risks, such as weight, alcohol intake, smoking status, cholesterol and blood pressure levels.

Something has to change, Holtermann said.

“Work ought to be organized, so the worker not become too fatigued or exhausted, with sufficient time/ability for recovery, so they have energy to do the health-promoting activities at leisure,” he said. “The worker ought to take responsibility for…improving physical activity during leisure, as well as getting sufficient recovery to recuperate from work.”

In an editorial accompanying the new study, Martin Halle and Melanie Heitkamp, of the Technical University of Munich in Germany, also called for change. “Companies should offer breaks and recovery time during work, sufficient recreational breaks and complementary exercise training for their employees, especially for workers in heavy manual jobs,” they wrote.

The research was published April 9 in the European Heart Journal.

Two American cardiologists agreed that leisure-time physical activity is important for promoting heart health and that occupational activity can be deleterious.

“In general, leisure-time physical activity, which is often of the endurance type, promotes cardiovascular health and reduces the risk of suffering a fatal heart attack,” said Dr. Evan Appelbaum, director of Men’s Health Boston. He was not involved in the new study.

“Occupational physical activity, typically more resistance-type, lacks adequate rest and recovery and may not reduce risk, and may increase risk of heart attack,” Appelbaum said.

Repeat bouts of high-intensity burst exercises such as those that may be part of manual labor can cause a very rapid rise in heart rate. Spikes in heart rate could help trigger cardiovascular crises “or promote higher levels of inflammation/injury that could promote heart disease over time,” Appelbaum added.

If the only exercise you get is at work, it’s not enough to boost heart health, said Dr. Guy Mintz. He directs cardiovascular health at Northwell Health’s Sandra Atlas Bass Heart Hospital in Manhasset, N.Y.

“Patients engage in physical activity during time away from work, and any physical activity at work is a bonus, not a replacement, for good aerobic activity,” Mintz said. “The findings serve as a wake-up call to companies to promote regular cardiovascular activities in the workday. This can range from yoga, to floor exercise like Tai Chi, to step competitions, etc., to gyms on site.”

More people are working from home due to the COVID-19 pandemic, and that could be a good thing, Mintz noted.

“There is a great opportunity to build in effective leisure-time activities into the workday to promote cardiovascular health and a happier and healthier workforce,” he said. “I recommend that all my patients engage in 40 minutes of continuous aerobic activity, like walking, at least four times a week, and there is no excuse not to achieve this goal while working from home.”
