What is Stanford's best sport

Ten minute workout: Even a little sport changes the body

What at first sounds like little sport leads to big changes in the body: jogging for ten minutes.

This is the result of a study by researchers from Stanford, USA. The level of more than half of the molecules observed changed after the test subjects had exercised for ten minutes.

The molecules in question were involved in metabolic, immune defense or inflammatory processes. So in ten minutes you can do something for your health.

Just jogging for ten minutes - sounds a bit like alibi sport, doesn't it? But it is not, as a new study by the Stanford University School of Medicine in the USA suggests. It showed that such a mini-sports unit is enough to change 9,815 molecules in your body.

Researchers have already dealt with the question of how exercise affects smaller groups of molecules in various studies. However, how individual types of molecules behave when we are physically active has never been the subject of any investigation.

The molecules are related to digestion, the immune system and metabolism

The new study, which was published in the journal “Cell”, is small; but it is an ambitious and meaningful attempt to document the tiny changes in blood that occur after a workout. The results of the study confirm something that scientists have known for years: that exercise is essential for health.

The researchers do not yet know exactly how the changes in each individual molecule will affect them. But what they do know is that they are related to various body functions. Some of the molecules that had changed were part of metabolic, digestive, or immune system functions. Others were involved in inflammatory processes or influenced how or how strongly the body reacts to insulin.

Genomicist and systems biologist Michael P. Snyder, one of the authors of the study, told the New York Times: “Before I thought, well, that's only nine minutes of exercise, how much is that supposed to change? A lot, as it turned out. "

This intensive and detailed research was only possible because the scientists had previously quantified the molecules of 100 adult men and women. From this pool of people they finally selected 36 people, including study author Michael P. Snyder. He chairs the genetics chair at Stanford University.

All test persons were between 40 and 75 years old, the spectrum ranged from “fit” to “overweight”. Their blood was drawn before and after they ran on a treadmill for ten minutes. The level of a large part of the total of 17,662 molecules - namely that of 9,815 - rose or fell measurably after the workout. In some cases the changed level persisted for a long time.

A blood test could determine your fitness in the future

What I have to say, however, is that the study was small and none of the test subjects was younger than 40 years. Also, only a single workout was observed - so Snyder and his colleagues are not yet able to draw any final conclusions about the proportion of molecules involved in the fitness context.

But Snyder is planning further experiments on the molecule level - then with longer workouts and more test subjects. During their research, Snyder and his team discovered thousands of molecules that were related to the fitness of the test subjects. These included markers for metabolism and immune responses.

Based on their results, the scientists have now developed an initial test. Perhaps, they believe, simple blood tests developed from research can be used to determine how fit a person is. If it works, Snyder will file a patent for this test.
