Decision Letter - Julio Alejandro Henriques Castro da Costa, Editor

Dear Dr. Stockdale,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please submit your revised manuscript by May 15 2025 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org . When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

  • A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
  • A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
  • An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: https://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols . Additionally, PLOS ONE offers an option for publishing peer-reviewed Lab Protocol articles, which describe protocols hosted on protocols.io. Read more information on sharing protocols at https://plos.org/protocols?utm_medium=editorial-email&utm_source=authorletters&utm_campaign=protocols .

We look forward to receiving your revised manuscript.

Reviewer #2: The introduction is well written and covers all important aspects that are needed in order to understand why this research is needed.

Methods:

- L177-180: Even though a power calculation was performed, it is not clear how the effect sizes used for calculation were determined. Was a similar study used as a reference? If yes, please cite this study. If not, please describe why you chose these values.

Results and the discussion are clear and concise. They also cover all relevant aspects and are written well.

Revision 1

Point-by-point response to the additional requirements outlined in the decision email:

1. Manuscript formatting: The manuscript has been revised to meet PLOS ONE's formatting and style requirements.

2. Consent from minors: The manuscript already includes a statement regarding informed consent from participants and their guardians:

“Players gave written informed consent and, where under 18 years old, written informed consent was sought from the parent or guardian for individuals to participate in this study, which was approved by Lancaster University Medical School (research ethics committee reference: LMS-22-3-Stockdale), and all testing was conducted in accordance with the Declaration of Helsinki.”

3. Financial disclosure: This section has been clarified as follows:

a. Robert Alexander Stockdale (lead/corresponding author) was a part-time paid employee at Burnley F.C. at the time of data collection (First Team Research & Development Assistant) who received a monthly salary from the club; but this employment ended in June 2023, prior to manuscript preparation.

b. No financial or material funding was received specifically for this study.

c. The funders had no role in the study design, data interpretation, manuscript preparation, or decision to publish.

d. The lead academy sports scientist at Burnley F.C. contributed to data collection and analysis using the MySprint app.

e. To confirm, the authors received no specific funding for this work.

In summary, the lead author worked for Burnley F.C. during data collection but not during writing; there was no direct funding/influence from the club; and while a club staff member assisted data collection, research was independently conducted.

4. Abstract: The abstract in the manuscript has been revised to match the version provided in the online submission form.

5. References: The reference list has been reviewed and updated as follows:

a. Reference 24: Reformatted per PLOS ONE guidelines.

b. Reference 26: Reformatted per PLOS ONE guidelines.

c. Reference 50: Reformatted as an app citation in accordance with guidelines.

d. Reference 54: Reformatted per PLOS ONE guidelines.

e. Reference 61: Reformatted appropriately.

6. Reviewer #2 – Methods (Lines 177–180):

In response to the reviewer’s request for clarification regarding the effect sizes used in the power analysis, we have added an explanation to the manuscript. Specifically, we now justify the choice of ICC values with reference to a relevant profiling study and conventional thresholds for acceptable and excellent reliability.

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
