Twelve minutes of sport would change blood biomarkers

Practicing short workouts could have more of an impact on our body than you might think. Indeed, according to a new study, an intense physical activity of twelve minutes would be sufficient to significantly modify the metabolic biomarkers in our blood.

Metabolites, products formed in the body during a metabolic process, can act as indicators of a person’s cardiovascular health and metabolism. According to Gregory Lewis, a heart failure and heart transplant specialist at Massachusetts General Hospital, “We already know a lot about the effects of physical exercise on the heart, vascular and inflammatory systems of the human body. Our study nevertheless provides a more complete overview of the impact that sport has on our metabolism. ”

The expert explains that he was particularly struck by the effects that short sports sessions can have on the levels of metabolites circulating in the blood, and which govern key functions of our body, such as insulin resistance, stress. oxidative, vascular reactivity, inflammation and longevity.

Favorable variations among circulating metabolites

To better understand how an intensive exercise session influences all metabolites in the human body, the research team measured the levels of 588 different circulating metabolites in 411 volunteers. The measurements were taken before and immediately after a workout of approximately twelve minutes.

After analyzing the different data, the scientists finally discovered that significant changes could be observed in more than 80% of circulating metabolites. Among these variations, some were particularly favorable. For example, the glutamate metabolite, associated with heart disease, diabetes and a shorter lifespan, is said to have decreased by 29% on average after workout.

The study indicates variations according to the sex and the body mass index of the volunteers. Signs of obesity could in particular limit certain benefits of intensive sports practice.

To date, a growing number of studies seem to show that getting some exercise is especially beneficial. In 2017, a search argued, for example, that one hour of weekly sport could decrease the risk of depression. According to cardiologist Ravi Shah, the new study could help patients who suffer from high blood pressure or other metabolic risk factors as a result of sports sessions.
