About this Research Topic

Background

Exercise positively influences the health of organs and systems, promoting longevity and counteracting the onset of chronic and/or degenerative diseases. In the context of the nervous system, exercise promotes the processes of neurogenesis, neuronal survival, neural transmission, and synaptic plasticity, improving and preserving cognitive abilities and mental health. For this reason, exercise is often referred to as an effective strategy aimed at both preventing and counteracting numerous pathological conditions affecting the nervous system. Indeed, in addition to reducing the risk of the onset of neurodegenerative diseases, such as Alzheimer's and Parkinson's, it is an excellent tool for the management of conditions affecting the nervous system such as epilepsy and stroke. Such exercise-induced neuroprotection could be due, at least in part, to the positive modulation of several neurotrophic factors such as brain-derived neurotrophic factor and nerve growth factor. In addition, other molecular actors of lipid or protein nature, as well as some regulatory RNAs, produced in response to exercise both in the brain and in peripheral tissues, are able to influence nervous system function and brain health. Collectively, these molecular products of exercise have recently been referred to as exerkines. Although some of these have been known for some years, others remain unknown highlighting the need to identify their nature and function on the nervous system.

The extraordinary complexity of the effects of exercise on the nervous system eludes our full understanding, highlighting the need for both further investigation of the neurophysiological responses to exercise and the mechanisms by which it counteracts diseases of the nervous system. Indeed, despite common awareness of the efficacy of exercise as a powerful neuroprotective and anti-aging strategy, many questions still remain about the type of exercise and training protocols to choose to optimize its effects. Recent evidence has shown that the expression of numerous exerkines, which can influence synaptic transmission and plasticity, can vary significantly depending on both the type of exercise practiced and the periods of training. Understanding the responses of the nervous system to exercise is critical to determining the role of exerkines in brain well-being, facilitating the development of exercise protocols tailored to the individual needs of healthy or pathological subjects.

The purpose of this Topic is to gather recent evidence related to brain adaptations to exercise in order to upgrade the improved knowledge about the mechanisms involved in improving health, as well as in disease prevention and management. Experts and specialists in exercise physiology are welcome to submit original articles, systematic reviews and meta-analyses aimed at investigating nervous system responses to exercise, with particular emphasis on the role of molecular products, in health and disease.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
