Table of Contents


Physical Activity and Nutrition (PAN) is an international, peer-reviewed, open access journal published quarterly (end of March, June, September, and December). It was launched by the Korean Society of Exercise Nutrition in 1997 and was previously titled Journal of Exercise Nutrition and Biochemistry (JENB). In 2020, it was changed to PAN, with the aim of reflecting and expanding the scope of the journal.

PAN features Original article, Short communication, Case reports, Review and Letter to the Editor on human and animal research as well as its related sub-disciplines. The journal seeks to publish high-quality scientific investigations that provide novel physiological knowledge across all areas of physical activity and/or nutrition, and demonstrate the synergistic effects of physical activity (including exercise and non-exercise physical activity) and nutrition, on maintaining health and fitness and preventing non-communicable diseases. The journal covers all aspects of public health; experimental biochemistry; experimental physiology; sports nutrition and supplementation; epidemiology; devices, tools, and technologies related to physical activity and/or nutrition.

Manuscripts must be written in English. Each manuscript is considered for publication with the understanding that it has not been submitted to any other journal. Upon acceptance for publication, manuscripts are subject to editorial review and revision.

2.1 General submission guidelines
All manuscripts must be submitted via the Electric Editorial System (EES) ( Authors may send queries concerning the submission process, manuscript status, or journal procedures to the Editorial Office ( All correspondence regarding submitted manuscripts will be through e-mail. Authors who are unable to provide an electronic version of their manuscript or are in circumstances that prevent online submission, must contact the Editorial Office prior to submission to discuss alternate options. A manuscript submission through the EES consists of a minimum of two distinct files: a cover letter and the manuscript. The EES accepts files from a wide range of word processing applications. However, the preferred file format is Microsoft Word. Please note that PDF files are not accepted for submission. When the files to be submitted have been uploaded, the system will automatically generate an electronic (PDF) proof, which is then used for peer review.
All documents must be typed in 12-point font and double-spaced with one-inch margins. All pages must be numbered consecutively. The manuscript file must follow the general instructions on style/arrangement, particularly the reference style. Tables (Excel or Word) and Figures (PPT) should be included as separate, individual files. Revised manuscripts must also be accompanied by a file (separate from the cover letter) with responses to reviewers' comments. The text, tables, and graphics must be submitted as separate files. Complete instructions for electronic artwork submission are accessible at the PAN home page. The website guides authors through the creation and submission of various files.

2.2 Cover letter
Provide a cover letter indicating the name, mailing address, telephone and fax numbers, and e-mail address of the corresponding author. The cover letter must specify that all authors have contributed to the work and agreed to submit the manuscript for publication in PAN, that no part of the work has been published before (other than in abstract form), and that all human and animal studies have been reviewed by appropriate ethics committees. All individuals listed as authors must have contributed substantially to the work, participated in the writing of the manuscript, and read and approved the submitted version. All individuals who have contributed to the writing of the manuscript must be listed as authors. The editor reserves the right to reject manuscripts that do not comply with these requirements.


3.1 Original article
The manuscript should include the text, references, and figure/ table legends. Do not include the figures or tables in this file.

Article Structure
Each article’s structure should adhere to the following order:
① Cover letter, ② Title page, ③ Abstract and keywords, ④ Introduction, ⑤ Methods, ⑥ Results, ⑦ Discussion, ⑧ Acknowledgments,⑨ References, ⑩ Tables, and ⑪ Figures and Figure legends.

Title page
On the first page of the blinded manuscript file, authors must provide only the title of the study and not include author information or authors’ affiliation details.

Abstract and keywords
The abstract must be a single paragraph of no more than 250 words, summarizing the Purpose, Methods, Results, and Conclusion. Abbreviations and citations must not be given in the abstract. Provide up to seven keywords below the abstract.

Main text
The main text should consist of Introduction, Methods, Results, and Discussion sections.

  • (1) The Introduction describes the purpose of the research and explains why the article is important. The background of the study and the relevant principles are summarized. The Introduction should not include the results or conclusions of the study.
  • (2) The Methods section presents the research methods. The subjects, experimental animals, or control groups involved in the study should be clearly described. The research methods should be presented in sufficient detail such that another researcher may duplicate the study. In particular, the methods used to diagnose subjects’ diseases or conditions and to control for observer bias should be explained. For equipment and reagents, the product name should be given, along with the manufacturer (along with headquarters city, state if applicable, and country) in parentheses. A reference may be provided for well-known methods, including methods for statistical analysis. If a method that is not yet well-known is used, or if a conventional method has been modified in the article, the relevant information should be briefly introduced in addition to providing a reference, and the rationale and pros and cons of the method should be supplied. Information regarding the acquisition of approval or consent of the IRB should be included. Ensure correct use of the terms sex (when reporting biological factors) and gender (identity, psychosocial or cultural factors), and, unless inappropriate, report the sex and/or gender of study participants, the sex of animals or cells, and describe the methods used to determine sex and gender. If the study was done involving an exclusive population, for example in only one sex, authors should justify why, except in obvious cases.
  • (3) The statistical method used should be described in detail so that the results in the article can be verified. If possible, the research findings should be quantified, and the indices that represent the measurement error or uncertainty (such as significance intervals) should be provided. Failure to present significant quantitative information, depending only on the statistical hypothesis test results, should be avoided, as in the case of providing only the P-value. If the research data is based on samples, a statistical verification process should be performed in order to generalize the results. The statistical computer software used should be specified.
  • (4) In the Results section, the results or findings should be described in a logical order, with tables and figures matched with the main text. Do not repeat in the main text all the data included in the tables and figures, but do describe the main points.
  • (5) In the Discussion section, important or novel findings in the results should be highlighted and conclusions made accordingly. Do not repeat statements that have already been made in Introduction and Results. The potential applicability and scope of application, as well as limitations in the interpretation of the results, may be described. Additionally, other relevant reports may be compared and discussed and then correlated with the purpose and conclusions of the study. Avoid making any conclusion that is not based on the study data or any baseless assertion. A new hypothesis may be suggested on the basis of the acquired data, and an appropriate method to verify the hypothesis should be included. When mentioning results that have not been shown in Results, they should be described as “data not shown.”

Manuscripts containing data that have been posted on the Internet for public access will not be considered for publication.


All manuscripts will be blinded and peer-reviewed by at least two anonymous reviewers selected by the editor and associate editors. The authors may request their manuscript to be reviewed by a specialist recommended by the authors. Letters to the Editor are reviewed and published at the editor’s discretion. Decision to accept, reject, or request revision will be communicated to the corresponding author at the earliest. When the final revised manuscript is deemed acceptable per PAN’s format and criteria, it will be scheduled for publication in the next available issue. Rejected manuscripts will not be peer-reviewed again.


When manuscripts are returned to authors for revision, a letter from the editor containing instructions will be provided, which must be followed carefully. A cover letter must accompany all resubmissions. Furthermore, point-to-point responses to comments from the editor, associate editor, and reviewers, as well as a brief description of the changes made in accordance with their feedback, must be provided at the time of resubmission. Nucleotide and polypeptide sequences must be updated by searching public databases [e.g. GeneBank, European Nucleotide Archives (ENA), dbSNP, Gene Expression Omnibus (GEO), PeptideAtlas, PRIDE] right before the submission of the revised manuscript. If the revised manuscript is not received within six months of the editorial board’s initial decision, or if other necessary arrangements have not been made by the editor, the manuscript is considered to have been withdrawn.
