According to Exercise physiologist Physical exercise generates molecular changes in the body.

According to exercise physiologist thousands of molecular changes occur in our bodies when we exercise. A good picture of the changes is in a research recently released by the Stanford University School of Medicine, in the United States. It is an orchestrated choreography of biological processes involving energy metabolism, oxidative stress, inflammation, tissue repair and growth factor response, the authors describe in the summary of the scientific journal Cell, where the work was published.

In all, they cataloged 9,815 altered molecules in the blood after an exercise session. According to the exercise physiologist, such a complete measurement may never have been made. These findings can result in a simple blood test capable of determining how well a person is physically fit, in addition to those already done today.

How the study was done To carry out the study, scientists recruited 36 men and women, with an average body mass index of 29 (within the normal range) and ages between 40 and 75 years. All underwent the VO test, which measures the peak oxygen uptake and consumption during exercise. A sample of the volunteers’ blood was taken before the test.

The participants then put on an oxygen measuring mask and ran on a slight incline until they reached the highest level of O2 utilization. Blood samples were collected again after 2 minutes, 15 minutes and 60 minutes.

In the first two minutes after exercise, markers of inflammation, tissue recovery and oxidative stress, a by-product of metabolism, skyrocketed shortly after the participants got off the treadmill, when the body started to recover. In the meantime, blood samples revealed that the body was synthesizing some amino acids for energy, but about 15 minutes later, it started using glucose, blood sugar, as fuel. According to exercise physiologist, leader of the research and one of those evaluated in the initiative, the body uses glucose reserves to recover from physical effort. Therefore, this process occurs a little later.

Exercise physiologist also noted some consistencies in the measurement range of the participants who performed better in the VO2 test, although this is not the initial intention. They observed a strong correlation between thousands of molecules, such as markers of immunity, metabolism and muscle activity, and an individual’s level of aerobic capacity.

The impacts of physical exercise are systemic. A neurotrophic factor (type of protein) that plays a central role in the development and physiology of the central nervous system. “The reasoning and learning abilities are also positively affected, as well as mental health“.

The practice promotes a balance in the availability of substances that make communication between neurons (neurotransmitters) associated with the processing of emotions. Among them, serotonin and dopamine.

Exercise physiologist say In the cardiovascular system, the increase in heart rate and blood circulation during training requires adaptation of the blood vessels. Substances involved in , such as nitric oxide and prostaglandins, are released, helping to regulate blood pressure.
