National Fitness Day | Nature: How does exercise change our bodies?

On this National Fitness Day, let's explore an exciting new discovery - how endurance exercise changes our bodies at a microscopic level. The latest scientific research reveals the magic of exercise for us. Let's learn about these amazing discoveries!

1. Exercise is more than just sweating and burning calories

Most of the time we think of exercise as making you sweat and burning calories. However, the latest research tells us that exercise does much more than that.

On May 1, 2024, the Molecular Sensors of Physical Activity Consortium (MoTrPAC) published a research paper titled "Temporal dynamics of the multi-omic response to endurance exercise training" in the journal Nature, revealing the molecular effects of endurance exercise on multiple tissues and organs.

This study explored in detail the effects of endurance exercise training on the human body through multi-omics analysis (including genomics, transcriptomics, proteomics and metabolomics). The study found that endurance exercise not only improves cardiopulmonary function and muscle strength, but also triggers a series of complex biological changes at the molecular level.

2. How does exercise change our bodies?

Scientists have used some very advanced technology to look at how exercise affects different parts of the body. They have found that when we engage in endurance exercise, our bodies undergo a complex series of changes:

Ⅰ. Muscle changes: Exercise can activate special cells in the muscles, which can help reduce inflammation and enhance our endurance.

Ⅱ. Liver and adipose tissue: Exercise can regulate the activities of these tissues, helping us better consume energy and break down fat.

III. Cardiopulmonary function: In addition to the known enhancement of cardiopulmonary function, the study has also discovered some new molecular mechanisms in this process.

3. Differences between men and women: Exercise effects will also be different

One interesting finding is that exercise affects men and women differently! Studies have found that in some ways, women’s bodies respond more to exercise than men. This may explain why women tend to perform better in some endurance sports.

4. Why is this research so important?

This study helps us better understand the importance of exercise to health. It not only confirms the benefits of exercise we already know, but also reveals many benefits of exercise that we didn't know before. These findings can help doctors and fitness trainers design more suitable exercise plans for each person.

5. Future Research

Although this study has already taught us a lot, the research team is not resting on their laurels. They plan to further study the effects of different types of exercise (such as strength training or high-intensity interval training) on ​​our bodies. These studies may help us find more effective exercise methods that are suitable for us.

This study proves once again that exercise can be a magical medicine! Not only does it make us feel better, it also improves our bodies on a micro level. So, on this National Fitness Day, we can look at exercise with a new understanding and start our fitness journey! Finally, remember that whether you are a man or a woman, no matter your age and body shape, moderate exercise will bring us benefits. Now, we can not only watch the Olympics, but also choose a sport we like and stick to it. Your body will definitely thank you!
