This is how different types of exercise affect heart-lung fitness

Madrid, October 17 (EUROPA PRESS) –

A new study led by researchers from Massachusetts General Hospital and the University of Boston (USA) presented new insights into how different types of exercise affect cardio-pulmonary fitness.

The study, published in the European Heart Journal, analyzed the ability of the heart and lungs, that is, the ability of the heart and lungs to supply oxygen to the muscles of the body during exercise, in 2,070 participants in the Framingham Heart Study, a long-term multi-generational study designed Identify factors that contribute to cardiovascular disease.

The most surprising finding of the study was that people with above-average daily steps or moderate to vigorous exercise had higher-than-average physical fitness, regardless of how long they were sitting.

“This suggests that most of the negative impact that sitting lifestyle has on fitness can be offset by higher levels of exercise and physical activity,” says the study’s first author Dr. Matthew Naor.

At work, participants were tested on physiological parameters during exercise and wore exercise monitoring for a week at one point, and again almost eight years later.

In this analysis, the researchers found that people who increased their daily steps, participated in moderate to vigorous exercise or reduced their sitting time between the two exams showed improvements in various aspects of cardio-respiratory fitness over time. , From warm-up to peak exercise and recovery. These results were largely consistent regardless of participants’ baseline activity level, age, sex, weight, and risk of heart disease.

For every minute of increased average exercise from moderate to vigorous, more than 3 minutes of walking at an intermediate pace or 14.6 minutes less sitting time will be required to achieve parallel changes in physical fitness.

In addition, increasing moderate to vigorous exercise by 17 minutes per day, performing an additional 4,312 steps per day (approximately 54 minutes at 80 steps per minute), or reducing 249 minutes of sitting time between the two exams was 5 percent. Another hundred VO2 max, or maximum oxygen uptake.

People with above-average or above-average number of steps of moderate to vigorous physical activity among study participants also had a higher-than-average maximum VO2, regardless of how long they were sitting during the day.

“We performed this analysis to understand the relative effects of change from sitting, low-level exercise, and moderate to vigorous activity in several areas of training fitness as objectively measured by the cardiopulmonary training test. “Walking or exercising moderately to vigorously will translate into changes in the ability to exercise, which in turn are known to greatly predict the long-term health condition,” explains the work’s lead author, Gregory D. Lewis.
