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 main idea of the manuscript is interesting and add to previous research. However, we consdier that the paper should be improved regarding the theoretical approach that sustains the main idea, the methods and the variables used. It was not clear the link between concepts such as tactical behaviour, variability, team spread, players' age and categories. Please add a first general paragraph introducing the futsal as a team sport that requires tactical behaviours. Also there is a need to improve the link between tactical behaviour and variability. L55 - distribution of players in the field? L76-78 - The issue of variability in differnt players age should be improved. There are previous studies that reported variability as a measure of adaptability while other reported variability as a measure of low proficiency. The authors should improve the explanation and clearly define and justify their position. L78-81 - players' age and players' experience are similar concepts? L95-96 - Please describe each group in analysis instead of the category and the championship separatedly. L120 - Why the authors used the described method to evaluate the pread of players in the court instead of convhull, strectch index or area of play. L157-158 - Add during the text upper or lower pannel according to the description. Reagrding the spectral analysis teh authors could choose to present the mean results on the text and maintain the figure or the opposite. It is not necessary to present the figure and the table. The information is redundant. Add the values of effect sizes between the 1st and 2nd half of the match in Table 1. It is not clear how the ball possession time-series was compared with the values of frequency of spread. A theoretical justification is required to improve the discussion of results. The authors only described the results and add some perspectives without a clear discusssion based on scientific evidences. Please improve it. Also, there is a need to present at the end of the manuscript the practical implications of the results for match analysis and training. The results means that worst teams tend to present high levels of variability in tspread than the best ones? What this imply? Reviewer #2: The present study aimed to analyze the time series of tactical behavior of futsal players from different categories, in the frequency domain, using an automatic tracking method. The topic is within the scope of the journal and deals with a relevant topic. The authors arrive at the conclusion that younger categories demonstrate higher tactical variability than professionals, which reflects the dynamics of play between attack and defense. Although the paper is already in a good shape, I have some concerns with regard to this paper, which need to be appropriately addressed prior to publication of this manuscript in its present form in Plos One. Major comments - In my opinion, the main concern refers to the real meaning of the dependent variable analyzed (i.e., team spread). Does this variable really represent the tactical behavior of the team? I think that tactical behavior is broader than simply team spread. Perhaps the team spread is a "portion" of tactical behavior. Also, does higher spread dynamics really represent greater tactical variability? This term (i.e., tactical variability) is too broad. Finally, is higher dynamic spread good or bad to players performance? It is confusing what the practical significance of this measure really is. - It may be interesting in this study to compare the spread dynamics according to the match status in the different categories (i.e., losing vs. drawing vs. winning). This would possibly help the auhors to better explain their results, rather than just characterizing the behavior of these variables across categories. Specific comments - I am not a English native speaker, but I suggest a language correction. - The aims of "abstract", introduction "and" discussion "are not in line. In my opinion, the best aim of this study is exposed in the discussion: "The aim of the present study was to analyze the time series of team spread during futsal official matches in the frequency domain for different categories.”. - I suggest separating the “Materials and Methods” section information into subtopics (e.g., participants and match sample, design, data collection, statistical analysis). - Please, describe in more details the contextual factors of the matches analysed (e.g., location, quality of opponents, outcome/status, team formation, playing time – see previous recommendation). These variables may influence your findings. - Maybe match status explains the results from comparing first vs. second period. - Figures are fuzzies and will need to be improved/changed during the review process. - Why the Figure 1 shows only 10 minutes of the matches? ********** 6.

(Please upload your review as an attachment if it exceeds 20,000 characters) Reviewer #2: All comments of the Academic Editor and Reviewers have been addressed. Therefore, I accept the manuscript in the current form. Reviewer #3: The article “Variability in tactical behavior of futsal teams from different categories” has a very relevant theme and I consider it to be appropriate to the scope of the PLos One. The variables of tactical behaviors in Futsal need further studies. A suggestion for better clarity of the work and possible discussions about the athletes' tactical behaviors, would it be to put more information about the registered games, for example, were they games of the qualifying or final phase championship? Was it necessary to win to continue in the championship? We have observed that the tactical behavior of some athletes changes according to the difficulty or value of the game played. I think it would be interesting to make this information about games clear at work, even for new questions in the future. In my opinion, after making such additions to the information in the description of the sample used, the work will be ready for publication, since the placements of the other reviewers were relevant and met by the vast majority of authors. I agree with all the other reviewers' comments, and since they were reviewed by the authors, I will not post again. Congratulation for their work! ********** 7.
