Journal requirements:   

When submitting your revision, we need you to address these additional requirements.

1. Please ensure that your manuscript meets PLOS ONE's style requirements, including those for file naming. The PLOS ONE style templates can be found at

https://journals.plos.org/plosone/s/file?id=wjVg/PLOSOne_formatting_sample_main_body.pdf and

https://journals.plos.org/plosone/s/file?id=ba62/PLOSOne_formatting_sample_title_authors_affiliations.pdf

2. We noticed you have some minor occurrence of overlapping text with the following previous publication(s), which needs to be addressed:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6020195/?report=abstract&tool=pmcentrez

https://www.birmingham.ac.uk/Documents/college-mds/trials/bctu/A-Renovascular/Basil-3-Protocol-v4.0-06-AUG-2019.pdf

In your revision ensure you cite all your sources (including your own works), and quote or rephrase any duplicated text outside the methods section. Further consideration is dependent on these concerns being addressed.

3. We note that the grant information you provided in the ‘Funding Information’ and ‘Financial Disclosure’ sections do not match. 

When you resubmit, please ensure that you provide the correct grant numbers for the awards you received for your study in the ‘Funding Information’ section.

4. In the online submission form, you indicated that [No datasets were generated or analysed during the current study. All relevant data from this study will be made available upon study completion.]. 

All PLOS journals now require all data underlying the findings described in their manuscript to be freely available to other researchers, either 1. In a public repository, 2. Within the manuscript itself, or 3. Uploaded as supplementary information.

This policy applies to all data except where public deposition would breach compliance with the protocol approved by your research ethics board. If your data cannot be made publicly available for ethical or legal reasons (e.g., public availability would compromise patient privacy), please explain your reasons on resubmission and your exemption request will be escalated for approval. 

5. Please review your reference list to ensure that it is complete and correct. If you have cited papers that have been retracted, please include the rationale for doing so in the manuscript text, or remove these references and replace them with relevant current references. Any changes to the reference list should be mentioned in the rebuttal letter that accompanies your revised manuscript. If you need to cite a retracted article, indicate the article’s retracted status in the References list and also include a citation and full reference for the retraction notice.

Additional Editor Comments:

Dear authors, after a careful evaluation of your manuscript and according to reviewers' suggestions our opinion is that it needs to be reviewed. We will be glad to evaluate your revised manuscript.

Best regards

Reviewer's Responses to Questions

Comments to the Author

1. Does the manuscript provide a valid rationale for the proposed study, with clearly identified and justified research questions?

The research question outlined is expected to address a valid academic problem or topic and contribute to the base of knowledge in the field.

Reviewer #1: Yes

Reviewer #2: Yes

**********

2. Is the protocol technically sound and planned in a manner that will lead to a meaningful outcome and allow testing the stated hypotheses?

The manuscript should describe the methods in sufficient detail to prevent undisclosed flexibility in the experimental procedure or analysis pipeline, including sufficient outcome-neutral conditions (e.g. necessary controls, absence of floor or ceiling effects) to test the proposed hypotheses and a statistical power analysis where applicable. As there may be aspects of the methodology and analysis which can only be refined once the work is undertaken, authors should outline potential assumptions and explicitly describe what aspects of the proposed analyses, if any, are exploratory.

Reviewer #1: Yes

Reviewer #2: Yes

**********

3. Is the methodology feasible and described in sufficient detail to allow the work to be replicable?

Descriptions of methods and materials in the protocol should be reported in sufficient detail for another researcher to reproduce all experiments and analyses. The protocol should describe the appropriate controls, sample size calculations, and replication needed to ensure that the data are robust and reproducible.

Reviewer #1: Yes

Reviewer #2: Yes

**********

4. Have the authors described where all data underlying the findings will be made available when the study is complete?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception, at the time of publication. The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

Reviewer #2: Yes

**********

5. Is the manuscript presented in an intelligible fashion and written in standard English?

PLOS ONE does not copyedit accepted manuscripts, so the language in submitted articles must be clear, correct, and unambiguous. Any typographical or grammatical errors should be corrected at revision, so please note any specific errors here.

Reviewer #1: Yes

Reviewer #2: Yes

**********

6. Review Comments to the Author

Please use the space provided to explain your answers to the questions above and, if applicable, provide comments about issues authors must address before this protocol can be accepted for publication.

Reviewer #1: PONE-D-24-22167: statistical review

This is a study protocol for a randomised controlled trial to assess clinical-efficacy/cost-effectiveness of prehabilitation/rehabilitation/patient-education among subjects undergoing first time atrial fibrillation ablation. The protocol relies on clearly identified research questions that can be tested by the suggested primary and secondary outcomes. The methods are standard and reproducible, sample size calculations rely on clearly stated hyptheses and methods for possible missing values are declared. Overall, I believe that this is a well-designed study protocol.

Reviewer #2: Authors presented an ambitious project to evaluate whether supervised sports practice, before and after an atrial fibrillation ablation, can determine differences in terms of outcome.

Study design seem to be appropriate for the purpose.

A question can arise: have authors considered that some athletes, suffering from AF, can be enrolled in the study? Can this occurrence introduce a bias in results interpretation?

Please specify this issue.

7. PLOS authors have the option to publish the peer review history of their article (what does this mean?). If published, this will include your full peer review and any attached files.

A question can arise: have authors considered that some athletes, suffering from AF, can be enrolled in the study? Can this occurrence introduce a bias in results interpretation?

Please specify this issue.

The question about athletes, particularly high-endurance level athletes, did come to mind when planning and developing the research protocol for CREED AF. The general consensus was to maintain generalizability of the study by being inclusive to as many individuals suffering with atrial fibrillation (AF) undergoing first time AF ablation as possible.

Concern may rest with higher than average VO2 peak seen in these individuals when matched with non-athletes. It has been observed that high-endurance athletes do also suffer with AF, with reduced physical ability/fitness prior to ablation, with improvement of most to near previous levels of fitness/exertion after ablation (Liu et al., 2022). The application of the CREED AF intervention, which aims at delivering a moderate level of exercise (tailored to the individual) alongside risk factor management, is equally applicable in these potential participants. Furthermore, the primary outcome measure is mean change in VO2 peak from baseline to primary follow-up at 10 +/-2 weeks post-ablation in the two groups; measuring and comparing the change would minimize any bias, if any, derived by inclusion of high-endurance athletes.

We have now included this in the discussion section on page 17
