IThe use of weights is healthier for the heart than a run or walk, new research has found.
Scientists observing the health records of more than 4,000 people concluded that while both forms of exercise reduce the risk of developing heart disease, static activities such as weight lifting or push ups have a greater effect than an equivalent amount of dynamic exercise. like running, walking or cycling.
Research challenges often support the assumption that so-called "cardiovascular" activities, such as racing, are of great benefit to the heart.
However, he backs up previous studies that suggest that static heavy exercise gives the circulatory system a better exercise because the oxygen expenditure is more intense.
The Medical Director of England recommends that adults engage in at least 150 minutes of moderate-intensity physical activity per week, including a mix of dynamic and static activity.
Professor Dr. Maia Smith, who led the research at St. George's University in Grenada, said: "Both strength training and aerobic activity seemed to have a healthy heart even in small numbers at the population level.
"Physicians should advise patients to exercise independently – both types of activities are beneficial.
"However, static activity seemed more beneficial than dynamic, and patients who did both types of exercise performed better than patients who simply increased the level of one type of activity."
The researchers analyzed cardiovascular risk factors, such as high blood pressure, overweight, diabetes and high cholesterol, as a function of static and / or self-reported activity in 4,086 American adults.
They participated in the National Health and Nutrition Examination Survey from 2005 to 2006.
The researchers then adjusted for age, ethnicity, gender and smoking and stratified by age, 21 to 44 years, or over 45 years.
In total, 36 percent of young people and 25 percent of older adults engaged in static activity, and 28 percent of young people and 21 percent of older adults engaged in dynamic activity.
Researchers found that involvement in any type of activity was associated with rates of cardiovascular disease risk factors of 30 to 70% lower, but associations were stronger for both static and youthful activity.
Prof. Smith said, "An interesting thing was that both static activity and dynamic activity were almost as popular with older people as younger ones.
"I believe this gives doctors the opportunity to advise their older patients that they fit perfectly into the gym or the road race.
"The important thing is to make sure they are practicing physical activity."
The research was presented at the Latin American Conference on Cardiology in Latin America in 2018 in Lima, Peru.
