Can fitness deal with fat? – Harvard Health Blog
In a recent study, researchers tried to answer the question posed in the title of this post. Before we delve deeper into the findings of this research and before it matches what we know about this topic, let’s define some key terms.
What do we mean by fitness and fat?
Fitness, also called cardiovascular fitness or cardiac breathing (CRF), is a measure of the performance of the heart, lungs, and muscles in the body. Muscle performance includes measures of strength and endurance. Because of the links between the mind and the body, adaptation also affects mental intelligence and emotional stability. Maximum oxygen consumption (VO2 max), the optimal measure of the amount of oxygen that a person can use during physical exercise is the optimal measure of CRF. However, self-reported physical activity is often used as a proxy for VO2 in most research, because evaluation is much easier and cheaper.
Obesity, as I discussed in a previous blog post, can be defined in many different ways. The body mass index (BMI), which takes into account your size, your height and weight, is the most widely used. However, we do know of such measures percentage of body fat, waist circumference, waist hips, proportion and waist height ratio Tell us much more than BMI about a person’s health, metabolic risk and risk of death. However, because of the ease of this measurement and the relatively low cost of it, BMI is the most widely used in research studies.
What was the purpose of the research study?
Going back final examination published in European Journal of Preventive Cardiology, the researchers wanted to study the “appropriate but fat” paradox. As some studies describe, the appropriate but fat paradox suggests that men who are also obese may also reduce their risk of cardiovascular disease by overcoming the effect of weight gain.
To address this paradox, our researchers evaluated the link between different categories of BMI and levels of physical activity and the prevalence of three major factors in major cardiovascular disease (GAH): hypertension (hypertension), high cholesterol, and diabetes. It was a large observational study that collected data from 527,662 participants at a specific time without follow-up.
They used to BMI incision standards to classify people as normal weight, overweight and obese. The levels of physical activity were as follows: inactive (not doing moderate and vigorous physical activity); active enough (moderate activity less than 150 minutes per week or vigorous physical activity less than 75 minutes per week); and regularly active (150 minutes or more a week of moderate physical activity or 75 minutes or more a week of vigorous physical activity, or a combination of both).
What were the results of the study?
The researchers concluded that being regularly active or active enough was a protection against hypertension, high cholesterol, and diabetes, compared to being inactive. Protection was related to the dose of hypertension and diabetes, i.e., higher levels of activity reduced the risk to a higher level.
However, regular or insufficient physical activity has not compensated for the negative consequences of being overweight or obese. In other words, people who were overweight or obese were at higher risk than their normal weight peers, regardless of their level of physical activity.
These findings reduce, but do not eliminate, the effects of overweight or obesity on physical activity.
What does this research mean to me?
While the findings of this study may lead some to believe that all efforts to improve health and endurance should be focused on weight management, we should not consider the benefits of weight-related exercises such as improvements in energy metabolism, oxidative stress, inflammation … tissue repair and immunity.
Achieving and maintaining a healthy body weight is important to reduce your risk of chronic illness, so your doctor may recommend weight loss treatments such as changes in behavior and lifestyle, medications, bariatric surgery, or some combination of the above. However, we must remember that obesity itself is a chronic disease, and one that is immediately out of control by an affected person.
But something we can control is the level of our physical activity. Running for yourself, walking, swimming, dancing or lifting light weights can always move us further, which while it helps us improve our health a bit, it also wins.
