WASHINGTON, Feb. 18 (Xinhua) – Active men and middle-aged men capable of performing more than 40 pumps have a much lower risk of developing cardiovascular disease than those who have fewer than 10, reveals a new study.
"This study highlights the importance of fitness for health and explains why clinicians should evaluate physical fitness at clinical encounters," said Stefanos Kales, senior author, professor in the Environmental Health Department at Harvard Chan School and Chief of Occupational Medicine at the Cambridge Health Alliance.
The study, published Friday in the weekly medical journal JAMA Network Open, badyzed data on the health of 1,104 active firefighters from 2000 to 2010.
The average age of the participants was 39.6 years and the average body mbad index of 28.7. Their lifting capacity was measured early in the study and each man then pbaded annual physical exams and medical and medical questionnaires, researchers said in a press release.
During the 10-year study period, 37 outcomes related to cardiovascular disease were reported. All but one case occurred in men who performed at least 40 pumps during the initial examination.
The researchers calculated that men capable of doing more than 40 pumps had a reduced risk of occurrence of cardiovascular disease by 96% compared to those who were able to do less than 10 pumps.
However, the researchers admitted that the study was based on a specialized group of people and that the results may not be applicable to women or men of other age groups, professions or conditions.
