A simple firefighter exercise test also reveals the risk of heart problems

BBecause heart disease is the leading cause of death in the United States, scientists are constantly looking for information that can predict who is at risk.

Potential risk factors ranging from prolonged sleep regimens to erectile dysfunction, a study published Friday in JAMA Network open now has a simple but convincing test of the risk of heart disease.

This new heart disease test is an exercise challenge that does not require treadmills, weights or virtual reality equipment. He may also be able to predict how much a person's heart could last up to 10 years.


Here is the test: If you can do at least 40 pumps a minute while maintaining a steady pace without stopping, these scientists suggest that your risk of heart disease is about 96 percent lower than those who can only do 10 in this period.


The study followed 1,104 firefighters of average age in Indiana between 2000 and 2010, all of whom performed the test. Each firefighter was told to start pumping in rhythm with a beat, such as a heartbeat or a metronome that was spinning at a rate of 80 beats per minute. They were told to stop when they successfully completed the challenge and stayed on their pace for the 80 beats, or missed three beats, or "stopped because of exhaustion or others. symptoms, "as the authors write in the journal.

In short, there was no pause or stop in the test. Part of the challenge was keeping up.

Stefanos Kales, Ph.D., lead author and professor at Harvard University, works with his team. The Chan School of Public Health Environmental Health Service has been collecting data on the physical examinations of these firefighters over the next 10 years. They found that firefighters able to perform at least 40 pumps at this rate were 96% less likely to develop heart disease in 10 years compared to those who could only perform 10 or less.

"Pushing ability is positively correlated with aerobic fitness and fitness," says Kales reverse. "These types of objective functional markers are generally good predictors of mortality."

More than 40 pumps at a speed of 80 BPM are not really fast. A total of 155 firefighters out of 1,104 managed to break 40 pumps in one minute and only 75 to 10; the highest number of firefighters, 389 to be exact, fell between 21 and 30 pumps for a minute – slightly below that ideal threshold. Kales says that he can easily do it himself, adding that it "feels good" but that it takes work. "These are healthy habits that I have maintained for many years," he says.

To be clear, this study does not prove that pumps or a particularly torn trunk can provide additional protection against heart disease. Rather, it suggests that the ability to lift may be a simple and effective way of assessing fitness or physical activity, which has predicted the future risk of cardiovascular disease.

Firefighters had to do as many pumps as possible in one minute at this rate.

In their article, the authors note that uplift capacity appeared to be a better predictor of the risk of future heart disease than VO2 max, which they also estimated from the sub-maximal treadmill test at the beginning of the year. # 39; study. However, they are reluctant to say that growth capacity is an excellent predictor, as it can change dramatically with age or BMI, other factors impacting heart disease.

Instead, it's a simple way to get a meaning of general fitness, which probably explains why the pumps are still a part of the exercise regimes of the police and firefighters, as the paper notes. They do not need special equipment, but simply an eagerness to cross this threshold and a stable stopwatch.

Observe now: Scientists have determined the minimum amount of physical activity needed to stimulate the brain.
