Boston – 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 Massachusetts General Hospital (MGH) and Boston University and by 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. Also, increase moderate to vigorous exercise by 17 minutes a day, take an additional 4,312 steps per day (approximately 54 minutes by 80 steps) or a 249-minute break between the two tests. 5% higher VO2Or taking too much oxygen. Individuals with moderate to severe or moderate to severe physical activity had higher VO levels among the study participants.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. MD is the director of the MGH Cardiac Testing Laboratory and the 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.

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