We all know that exercise is important and that exercise reduces our risk of heart disease and possibly helps us live longer, but how much exercise and exercise can change a person’s fitness level? New research led by researchers at Harvard-related Massachusetts General Hospital (MGH) and Boston University European Heart Journal Provides specific details.

The study looked at cardiovascular exercise or the ability of the heart and lungs to provide oxygen to the muscles during exercise, with 2,070 participants in the Framingham Heart Study, a long-term multidisciplinary study identifying factors contributing to cardiovascular disease. Generation study participants. Participants tested their physiological parameters during exercise and wore exercise monitors at once for one week, then again eight years later.

In this analysis, researchers found that people who increased their daily activity, participated in moderate to moderate physical activity, or reduced sitting time between the two tests showed improvements in cardiovascular fitness during different exercise sessions. From warm-up to high-intensity exercise to recovery. These findings are generally consistent regardless of participants’ initial activity level, age, sex, weight, and risk of heart disease.

On average, moderate to vigorous exercise requires more than 3 minutes of moderate walking or 14.6 minutes of exercise per minute. Increasing the range from moderate to vigorous exercise by 17 minutes per day, taking an additional 4,312 steps per day (approximately 54 minutes to 80 steps per minute) or a 249-minute break between the two tests is associated with 5 percent. High peak VO2Or taking too much oxygen.

Researchers found that among the study participants, the average number of steps or the average person with moderate to vigorous physical activity received the highest level of VO.2 Values, no matter how competitive they are during the day.

“We conducted this analysis to understand the relative impact of low-intensity exercise, low-intensity exercise, and moderate-to-vigorous activity on a variety of physical activities,” said senior author Gregory D. Director of the Cardio-Pulmonary Exercise Laboratory at MGH and Medical Director of the MGH Heart Attack and Heart Transplant Program. “The results show that for adults, a reduction in rest, walking or moderate-intensity exercise can translate into physical activity changes, which in turn predicts long-term health.

“The most striking finding of our study is that individuals with moderate to high levels of activity or moderate to vigorous physical activity per day had a higher level of fitness than average. According to Matthew Naior, the study’s first author, assistant professor of medicine at Aram Chobanian Cardiovascular Department at the University of Boston Medical Center for Medicine and Preventive Medicine and Epidemiology.

“Physical activity is the cornerstone of modern cardiovascular disease prevention,” said Ravi Shah, co-author of the study, who is the director of clinical and translational research at Cardiology at Vanderbilt. “These results support ongoing efforts to improve overall cardio-metabolic health as well as exercise.”
