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 present study aimed to investigate: “DIVERSIFICATION OF YOUNG HOCKEY PLAYERS’ ACTIVE BEHAVIOURS: 4 CONTRIBUTION OF INDIVIDUAL, SOCIAL, AND ENVIRONMENTAL FACTORS”

Follow bellow my considerations:

1) Abstract: adjust numbers after comma. Insert the main results in the abstract.

2) Introduction: several phrases don’t have references. Please, add it.

3) Methods: Is the authors compared the responses of age rank, competitive level, and sexes? Are the statistical analyses employed was enough to support the results?

4) Discussion: please, change in all information in the article the term “we”. Change to it was or other.

5) What the reproducibility of the fill these questionnaires? Are the authors measured it?

6) The main point refers to aggregate all adolescents in a unique group. I believe that the groups should be split in competitive level and sex.

7) Is the sample size for woman enough? Is represented the practitioners in Canada?

Reviewer #2: This manuscript used a cross-sectional descriptive study to investigate the predisposing, enabling, and reinforcing factors that potentially influence active behaviours in adolescents.

The topic of the manuscript is appropriate for the Journal.

I believe the study findings are of great interest to investigators and stakeholders.

This paper would benefit from some minor English language editing, as few grammatical errors were noted thought the manuscript.

Materials and Methods: The main comment I leave is related to the procedure for applying the questionnaire. I ask the authors to consider a possible bias in the results based on the questionnaires collected in the second approach (during the tournaments). Having been the questionnaires applied at the end of the final game, could not have influenced some of the answers? Can this be considered a limitation of the study?

Sufficient details about the process are provided. Statistical analyses used are appropriate. The methods are appropriate and well described.

Results: Information is clearly provided on tables; however, the pictures appeared in the document with poor quality, hindering a more accurate visualization of the results.

Figures and tables: The three tables are clear and well designed. The three figures are with low definition impairing reading, especially figure 3.

References: There are 42, and all seem appropriate.

Reviewer #3: The present paper is interesting and well-structured. However, there are few issues that are suggested to be addressed to the manuscript prior to publication:

It is suggested to rewrite the title, is big and not attractive.

The abstract at some point does not make sense. First the authors expose that there is a substantial proportion of adolescents that don’t meet Canadian guidelines to have a good levels of physical activity, and then the authors want to know more about the physical activity participation of adolescents already involved in an organized sport?

Why authors did not consider add girls to the study’s sample?

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 #2: The authors present improvements in the article that allow the reader to be clarified, especially regarding some methodological aspects.

The authors should review the captions in tables 1 and 2, as they do not allow identifying some abbreviations. More specifically, in table 1, the abbreviations for "M" and "SD" are not defined in the caption. In table 2, are not identified in the caption, the abbreviations corresponding to the variables, which would facilitate the interpretation of the reader.

Reviewer #3: The present paper is interesting and has a significant content. Moreover, it is appeared to be suitable to highlight the premise of this manuscript is a worthy one, and the authors spent a great time in the research and structuring. However, there are some questions that need to be addressed to the manuscript prior to publication.

Introduction

In this section, it is considered that the pertinence of the study needs to be clearer. What is the real importance of the present study?

Methods

The authors should homogenize the terms that use all over the manuscript. In the introduction for the areas of physical activity used the following order and nomenclature: 1) organized ice hockey, 2) leisure-time sports, 3) weight training, and 4) cardiovascular training, however, in the variables and instruments, the authors change the order before and use different terms (e.g.: aerobic capacity). Please uniformize it.

Results

Table 1 need to be checked, there are wrong values (SD = 88 ?, or 1.700?), there also missing parenthesis.

Discussion

The authors mentioned in this section that previous studies mainly focused on younger participantes (8-12 years old), but did not referenced. It is suggested to add those studies mentioned before.

Perspective of future researches

The authors exposed that particular relationship has already been tested in some studies, but they only mentioned one study (Amorose et al., 2016). Please add more studies to justify the sentence.
