5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: The study delivered a mixed-method questionnaire to more than 200 practitioners to evaluate the knowledge, adherence, practices, and challenges of practitioners responsible for delivering long-term athletic development. The manuscript is well written and the methods are efficiently reported. The results are reported with many details; this makes the manuscript quite long. However, the conclusions and the summarizing figure makes the core finding clearly identifiable. The results are interpreted correctly and discussed in light of the updated literature. For these reasons, I want to congratulate the Authors on this study.

I only have one major comment (easily amendable): the national distribution of the practitioners should be included as the nationality may affect their sport-specific education. The results should be discussed accordingly.

Few minor comments:

• Line 128 – while it is clear to me, it may be useful to explicit what “A-Levels / BTEC” means for stranger readers.

• Was the questionnaire delivered only in English? Please include this information.

Reviewer #2: Interesting study that explores the ''knowledge, adherence, practices, and challenges of practitioners

responsible for delivering long-term athletic development.'' This study may be the only that went that far in documenting adherence and practices. This was realized with an appropriate methodological approach (i.e. mixed). Well written.

Page 6: The sample is heterogeneous. It is surprising that they are all participants considered as ''practitionners responsible for delivering long-term athletic development''. Like parents?

The description of the sample should be upgraded. In the discussion, a contextualization of the sample should be included to better explain what are the implicaions in terms of generalization of findings/conclusions/recommendations.

In the different sports represented you mention hockey, is it field or ice?

Page 10 Table 2: Definition 3 and 4 seem redundant

I am a little bit surprised that social desirability was not mentionned in the ''Strengths and Limitations'' section. When professionals are asked about their respect of best practices, they tend to self-score higher. Self-reporting of practice,

may be subject to social desirability bias. Nobody is against virtue. However, I don't believe that it may affect comparison of adherence between pillars. It may explain however, the saturation of the scores (table 5). Also to what extent do these strongly adherent practitionners really apply what they preach in their practice? With some of them you were able to obtain concrete examples of action (e.g. p21) but with most only general statements were declared.

Page 15: Also, why is there a gap between sport leaders and other ''practitionners'' ? Isn't it worrisome that sport leaders don't understand that progression and individualisation are essential for long-term development.

On page 32 it is written that : ''This study is the first to investigate the knowledge, adherence, practices, and challenges of

practitioners’ responsible for delivering long-term athletic development.'' It is not true. Indeed, I am surprised that the research on the Canadian version of LTAD seems to have been evacuated. The following references have information that are relevant for the present study and investigated ''the knowledge, adherence, practices, and challenges of PTAD delivery:

Revision 1

Please note all line numbers refer to the tracked change document

Reviewer #1:

The study delivered a mixed-method questionnaire to more than 200 practitioners to evaluate the knowledge, adherence, practices, and challenges of practitioners responsible for delivering long-term athletic development. The manuscript is well written and the methods are efficiently reported. The results are reported with many details; this makes the manuscript quite long. However, the conclusions and the summarizing figure makes the core finding clearly identifiable. The results are interpreted correctly and discussed in light of the updated literature. For these reasons, I want to congratulate the Authors on this study.

Thank you very much for your positive comments.

I only have one major comment (easily amendable): the national distribution of the practitioners should be included as the nationality may affect their sport-specific education. The results should be discussed accordingly.

This is a really interesting point. Although this would seem easily amendable, unfortunately, we could not provide this level of information within the paper. While our survey provided latitude and longitude destinations for participants, the survey (using Qualtrics) only collected this information for 130 of our 236 participants (I don’t know why this was the case). Therefore, I don’t think it is appropriate to report the nationality based on the limited information available. I have included this as a limitation on lines 758-759

Few minor comments:

• Line 128 – while it is clear to me, it may be useful to explicit what “A-Levels / BTEC” means for stranger readers.

I have added the meaning of A-Levels and BTECs on lie 131-132

• Was the questionnaire delivered only in English? Please include this information.

In English only has been added to line 149 

Reviewer #2:

Interesting study that explores the ''knowledge, adherence, practices, and challenges of practitioners responsible for delivering long-term athletic development.'' This study may be the only that went that far in documenting adherence and practices. This was realized with an appropriate methodological approach (i.e. mixed). Well written.

Thank you for your positive comments and suggestions below. We have addressed each comment below.

Page 6: The sample is heterogeneous. It is surprising that they are all participants considered as ''practitionners responsible for delivering long-term athletic development''. Like parents?

We agree the sample is heterogenous, which provides a strength and weakness of the study (see study strengths and limitations). We have removed parents from line 126 as we agree they were not a practitioner. All data has remained within the study as although two participants identified their primary role as a parent they also had a secondary ‘practitioner’ role.

The description of the sample should be upgraded. In the discussion, a contextualization of the sample should be included to better explain what are the implications in terms of generalization of findings/conclusions/recommendations.

We have presented the data that we collected and are unsure how to upgrade the description of the sample further. However, we acknowledge that we could present the interactions between the sample but every participant had a different range of qualifications, experiences and worked in multiple roles and contexts making the presentation of such information difficult and likely confusing. However, we have updated the discussion, strengths and limitations and conclusion sections to re-emphasise the generalisation of the findings in relation to the broad sample used.

In the different sports represented you mention hockey, is it field or ice?

It was actually both field and ice hockey. This has been added on line 135.

Page 10 Table 2: Definition 3 and 4 seem redundant

Thank you for this comment. While we acknowledge your points, the definitions are used to show examples of practitioners’ definitions of athleticism. Definition 3 and 4 are similar but definition 4 states in a range of physical activities aligned to the multiple environments part of the definition (see table below). As such we would respectfully prefer to keep the definitions within the table.

3 (33) 15.1% ‘’one’s ability to perform a broad range of movements, with confidence and competence, to develop a range of physical qualities including strength, speed, power, agility and endurance’’

4 (3) 2.7% ‘’the ability to participate confidently and competently in a range of physical activities and in doing so demonstrate flow, strength, speed and coordinated range of motion’’

I am a little bit surprised that social desirability was not mentionned in the ''Strengths and Limitations'' section. When professionals are asked about their respect of best practices, they tend to self-score higher. Self-reporting of practice, may be subject to social desirability bias. Nobody is against virtue. However, I don't believe that it may affect comparison of adherence between pillars. It may explain however, the saturation of the scores (table 5). Also to what extent do these strongly adherent practitionners really apply what they preach in their practice? With some of them you were able to obtain concrete examples of action (e.g. p21) but with most only general statements were declared.

This is a really interesting comment. We have now referred to social desirability bias on lines 626-628. We have also acknowledged social desirability and score saturation as a study limitation (Lines 759-761).

In relation to your point re practising what they preach, we refer to this within lines 627-631 to provide examples of where further research is required to understand this.

Page 15: Also, why is there a gap between sport leaders and other ''practitionners'' ? Isn't it worrisome that sport leaders don't understand that progression and individualisation are essential for long-term development.

While these differences were not significant we did highlight that sport leaders and others only scored a 3 for Pillar 9 (progress and individualise training) on Line 617. This question was in relation to their practices and we have added an explanation on line 617-618 why this may be the case.

On page 32 it is written that : ''This study is the first to investigate the knowledge, adherence, practices, and challenges of practitioners’ responsible for delivering long-term athletic development.'' It is not true. Indeed, I am surprised that the research on the Canadian version of LTAD seems to have been evacuated. The following references have information that are relevant for the present study and investigated ''the knowledge, adherence, practices, and challenges of PTAD delivery:

Thank you for this comment. There seems some difference here between the Canadian long-term athlete development model (as per the references below) and the focus on “long-term athletic development”, building on the NSCA position statement (Lloyd et al., 2016). We introduce these concepts in the introduction (paragraph 1) and the move away from a ‘talent only’ strategy as proposed by existing models. Therefore, while studies may have examined LTAD practices of coaches (as per your list below), we are not aware of any study that has explored the practices related to long-term athletic development according to the definition of Lloyd et al., (2016) “habitual development of athleticism over time to improve health and fitness, enhance physical performance, reduce the relative risk of injury, and develop the confidence and competence of all youth”.

As such we have tried to emphasise this point in the introduction and include some of the references you provided below within the introduction. Please see lines 83-84.
