Answers for Reviewers
Many thanks to both Reviewers for their comments and suggestions. Thanks to this, our article will be rethought and improved.
For Reviewer no. 1
- There are no information about utilitarian purposes of the research.
Answer: The research results are useful for trainers and researchers, presenting a tool that is easy to apply in the conditions of a training room and a short training unit time. The ease of testing strength and dexterity and their connection with "grappling" sports constitute a valuable resource for the practice of sports training.
Added to text – lines 73-76.
- The same data are on table 2 and figures (1 & 2).
Answer: The duplicate data have been removed form manuscript (table 2). The charts have been supplemented with additional data. All references to table 2 have been removed from the text (line: 169, 179).
- There are no marking units on figure 1.
Answer: The figure 1 has been changed.
- There are summary instead conclusions.
Answer: The conclusions has been rebuilt.
The conclusion was added that “The Ditrich stick and dynamometer, these simple research tools, can still be useful in the practice of sport, in particular in the fighting arts analysed here.”
- References should be completed.
Answer: Five items were added and everything was put in order.

Reviewer 2 Report
General comments
This study looked at using reaction time (assessed via Ditrich rod test method) and grip strength (assessed via handgrip dynamometer) to determine differences between judokas and jujutsu martial art practitioners of similar experience and expertise. Although the article has potential, the writing is difficult to follow. Authors’ writing requires extensive proof reading and a re-write from an native English language speaker with experience of the subject area (motor control and martial arts). That said, content of the work is not really motor skills, it is grip strength and reaction time. The rationale of the study is unclear, why do this study in these populations,the samples are not well described and not really indicative of ‘martial arts; let alone specific to judo, etc.
Specific comments
Abstract- Data need to be presented here. State the hypothesis more specifically if you are going to refer to them, and report your results (correlations, t-tests, etc). Clearly you need to be brief, but you can state actual results. Why is karate study talked about here? For example, ‘positive correlation was demonstrated in the group of German judokas between the age and reaction time of the subjects (r= 0.66, p < 0.05), and in the group of jujutsu subjects between body weight and the reaction time (r =0.49, p<0.05).
Introduction
Page 1, line 34-35, this sentence is very unclear and difficult to interpret. In addition, I am not sure the first two sentence are necessary, I recommend removing lines 34-36 and starting the paper with ‘Combat sports involving wrestling have their special characteristics,…’
Line 39, However, the reference for the previous sentence does not exist, or is a mistake, as you only have 28 references cited and this one is listed as 30.

Page 4, line 170, report SD with means here and on page 5 line 172.
Page 5, I suggest re-phrasing lines 172-174. Hand grip strength among judokas and jujutsu practitioners significantly differed by country of origin.

The rationale of the study is unclear, why do this study in these populations, the samples are not well described and not really indicative of ‘martial arts; let alone specific to judo, etc.
Answer: The text was consulted with colleagues working in the field of motor control to improve the language.
The justification for the selection of the scientific problem and the selection of groups (from sports judo and traditional jujutsu) was justified in the Introduction.

…less important to analyze whether the study subjects come from Poland or Germany, and instead assess their level of overall activity.
Answer: Thank you very much for your suggestion. The text has been corrected.
Conclusion
This entire section is very difficult to follow, so most of information is unclear.
Answer: The conclusions have been rebuilt.
The results of the analyzes allowed to formulate the following conclusions:
- Simple reaction time in response to a visual stimulus is shorter in jujutsu practitioners (p= 0.003).
- There were no statistically significant differences between jujutsu and judo players in the dynamometric handgrip measurement.
- The two-factor analysis of variance showed a statistically significant effect of the interaction of country and martial arts variables on the results obtained by the respondents in the reaction speed test. Also, the country of origin of the players statistically significantly differentiated, regardless of the type of martial arts, the average results obtained in the test with the Ditrich rod.
- The Pearson's linear correlation values determined for the studied groups indicate a negative impact of ageing players on their reaction speed. The weight of the players also had a negative influence on the reaction speed.
- The weight and age of the competitors (especially in judo) had a significant (p < 0.05) influence on the results obtained in the dynamometer measurement of hand strength.
- The Ditrich rod and dynamometer, these simple research tools, can still be useful in the practice of sport, in particular in the fighting arts analysed here.
Table 1, Title- Basic characteristics of sample
Answer: The title has been changed.
Age needs units of measure (yrs)
Answer: Thank you for your suggestion. The unit of measure has been added.
All participants are right-handed? Unusual.
Answer: In this group all participants were right-handed.
Your #2 notation under the table, I would move into the table. So, Dominant hand, n(%) and Training experience, n(%).
Answer: Thank you for your suggestion. #2 notation has been moved into the table.
Table 2, Title- Mean values (± SD) obtained in the individual tests.
Answer: Thank you for your suggestion. Table 2 has been removed from the manuscript. Based on your advice, we decided to change the titles of the figures.
Table 3- Effect spelled incorrectly
Answer: Corrected. The symbol of effect “Eta2p” has been replaced with the symbol “h2”.
As I’m not sure if all versions will show the differently coloured ink, perhaps a note and an asterisk to indicate significant effects?
Answer: Thank you for your valuable comment. The asterisk has been added to the results indicating significant effects. To the description of the tables, the note has been added.
Table 4, Age needs units of measure (yrs)
Answer: The unit of measure has been added to Table 4 (now Table 3).
Were these correlations significant at the 0.05 level? State that below the table.
Answer: Corrected. The note has been added below the table.
Figure 1- it is unclear to what the statistics on the figure refer.
Answer: Corrected. Figures 1–2 and the titles of these figures have been changed.
Handgrip needs units of measure on the axis
Answer: Corrected. The units have been added to the axis.
Font size is different between title and figure.
Answer: Thank you for your suggestion. The font was standardized.

Reviewer 3 Report
The Article “Indicators of targeted physical fitness in judo and jujutsu - pre-2 liminary results of research” requires several changes before it will be published. The major strength of the study is this study practical application. However, there are some remarks concerning this article:
- The aim of this study is a comparison of practitioners of judo and a similar martial art jujutsu with 13 regard to manual abilities. It is not clear what does it mean “manual abilities”? Additionally, in the title of the article mentioned “targeted training”, it would be more valuable if it will be more explained in the introduction (is ir related to the training periodization, or to the purposeful training or etc.). As well as is important at least to mention what other physical components are important for the performance / competitive activities in judo or jujutsu.
- I would suggest calling in all the article physical fitness components names, but not to call them as a test names. Some terms used in the article not always correctly (e.g. “reaction rate test” – line 178).
- By the way, as a key word presented “dexterity” (even it is better to call in sport setting “agility”), but not any test or results related to that presented in the article.
- There are some parts in the article to much repetitive.
- It is not clear why it is necessary in this research include data form observations and taking notes? (e.g. lines 58-61).
- Additionally, in my opinion, it is strange to mention that selection of participants was considered as representative if it was just sportsmen form one sport club (line 90-91). Moreover, the number of the participants in the research in several places are presented not the same (line 16, line 87-88, line 98-100).
- In the material and methods part, I would suggest presenting all the material more systematically, because now it looks a little bit chaotically.
- All the tests presented without references. The explanation grasping Ditrich’s rod test presented without measured units. It is not clear was both tests done with dominant hand or not? I think both hands are very important in judo and jujutsu, therefore it would be more valuable to present data form both hands.
- Statistical analysis and used test for the comparison has to be explained in statistical methods, but not in the results part (e.g. lines 156-159).
- I would suggest into results include BMI as an indicator of body composition and try to find some relations to other fitness components.
- There is not in every place mentioned difference, although it could be (e.g. table 1 German jujutsu group weight in comparison to other results). Additionally in this table it is not clear presentation of training experience in dan, maybe it is even would be valuable to group data form 4 dan and below, because there only 5 subjects and just in German jujutsu group (if I understood correctly).
- Table 2 and figure 1 and 2 shoes data repetition.
- In Figure 3 title explains only one physical fitness component (reaction time) effect interaction for country and martial art. What about effect of dynamometry?
- In table 4 presented corelation without significance level, this is not also explained in the text. Link to the table presented below the table (e.g. line 210).
- There is some material presented in discussion part not really related to this discussed topic.
Before publication, in my opinion, article must be improved.

The Article “Indicators of targeted physical fitness in judo and jujutsu - preliminary results of research” requires several changes before it will be published. The major strength of the study is this study practical application. However, there are some remarks concerning this article:
The aim of this study is a comparison of practitioners of judo and a similar martial art jujutsu with 13 regard to manual abilities. It is not clear what does it mean “manual abilities”? Additionally, in the title of the article mentioned “targeted training”, it would be more valuable if it will be more explained in the introduction (is it related to the training periodization, or to the purposeful training or etc.). As well as is important at least to mention what other physical components are important for the performance / competitive activities in judo or jujutsu.
Answer: An explanation has been added:
The "targeted physical fitness" is the targeted physical fitness for judo and jujutsu. It involves the development of “manual skills” or “manual abilities” that determine the effectiveness of technical-tactical activities. Most of the fighting techniques in both fighting arts are so-called hand techniques (grips, throws, etc.).
I would suggest calling in all the article physical fitness components names, but not to call them as a test names. Some terms used in the article not always correctly (e.g. “reaction rate test” – line 178).
Answer: Thank you very much for your suggestion. The text has been corrected.
By the way, as a key word presented “dexterity” (even it is better to call in sport setting “agility”), but not any test or results related to that presented in the article.
Answer: Indeed, the research carried out is about dexterity (which is indirectly checked by the Ditrich test) and the improvement of directed fitness.
There are some parts in the article to much repetitive.
It is not clear why it is necessary in this research include data form observations and taking notes? (e.g. lines 58-61).
Answer: Not without significance is the over 50-year participant observation of one of the co-authors in the judo and jujutsu community, who first as a competitor and then a trainer with a master's degree knows the specifics of both martial arts from the inside. This is important for a general interpretation of the issues raised here.
Additionally, in my opinion, it is strange to mention that selection of participants was considered as representative if it was just sportsmen form one sport club (line 90-91).
Answer: The selection was deliberate, but made in such a way as to meet the criterion of representativeness, while maintaining the number of samples of the same order (however, they do not have to be equal).
Moreover, the number of the participants in the research in several places are presented not the same (line 16, line 87-88, line 98-100).
Answer: The number of participants has been checked. The description of groups has been written more clearly.
In the material and methods part, I would suggest presenting all the material more systematically, because now it looks a little bit chaotically.
Answer: Thank you for your suggestion. Material and methods have been changed partially.
All the tests presented without references. The explanation grasping Ditrich’s rod test presented without measured units.
Answer: The explanation for grasping Ditrich’s rod test has been corrected.
It is not clear was both tests done with dominant hand or not? I think both hands are very important in judo and jujutsu, therefore it would be more valuable to present data form both hands.
Answer: In this group all participants were right-handed. Both tests were done with the dominant hand. The other hand wasn't tested.
Statistical analysis and used test for the comparison has to be explained in statistical methods, but not in the results part (e.g. lines 156-159).
Answer: Thank you for your suggestion. Description of used statistical tests moved to statistical methods.
I would suggest into results include BMI as an indicator of body composition and try to find some relations to other fitness components.
Answer: The BMI measurement, which gives a similar result of an athletic bodybuilder and an obese person, is omitted and only gives an idea of the leanness in body proportions.
There is not in every place mentioned difference, although it could be (e.g. table 1 German jujutsu group weight in comparison to other results). Additionally in this table it is not clear presentation of training experience in dan, maybe it is even would be valuable to group data form 4 dan and below, because there only 5 subjects and just in German jujutsu group (if I understood correctly).
Answer: Thank you for your suggestion. Table 1 has been changed.
Table 2 and figure 1 and 2 shoes data repetition.
Answer: The duplicate data have been removed form manuscript (table 2). The charts have been supplemented with additional data from table 2. All references to table 2 have been removed from the text (line: 169, 179).
In Figure 3 title explains only one physical fitness component (reaction time) effect interaction for country and martial art. What about effect of dynamometry?
Answer: We didn't illustrate the interaction effect (Two-way ANOVA) for hand strength, because the dependent variable didn't meet the assumption of normal distribution in the groups under consideration.
In table 4 presented correlation without significance level, this is not also explained in the text. Link to the table presented below the table (e.g. line 210).
Answer: Information about the statistical significance assumed in the analysis (statistical significance at the 0.05 level) was added to the description of the tables.
There is some material presented in discussion part not really related to this discussed topic.
Answer: Among the co-authors, we selected the list of references, rejecting thematically related to a small extent (like items 4, 25, 38 of the original version), and adding better thematically correlated.
Before publication, in my opinion, article must be improved.
Answers: Thank you very much for your valuable comments and suggestions that helped to improve the content of this work.

Round 2
Reviewer 2 Report
The authors are to be commended for this much-improved version of the paper. There are still a few minor issues, see specific comments, but the language and structure are both much better.
Page 2 lines 48-52, this section is still not entirely clear.
Lines 54-57, different paragraph spacing and not consistent with the rest of the paper. Topic needs a transition, as it does not flow from previous section.
Lines 78-81, much better phrasing
Page 3, line 110, Coordination ability and reaction time…
Line 113-114, Selected motor and psychomotor abilities, that are characteristic and dominant among subjects practicing the martial art such as judo and jujutsu, were chosen to measure and compare.
Lines 129-136, description of Ditrich method is much improved.
Page 4, line 143-144, word missing. The better measurement of the two tests was selected for further analysis
Page 5, line 178-179, it might be better stated as ‘jujitsu participants’ or judo participants’
Table 2, Efect is still spelled incorrectly: Effect
Shift note left under table
Table 3, shift note left under table
Page 6, line 209, it was found that… (apologies, I am not sure what I was looking at before, you were correct the first time).
Page 8, line 268 analysis: The results of the analysis allowed the authors to formulate the following conclusions:
Line 275-277, awkward phrasing. Suggestion: Also, regardless of the type of martial arts, the average results obtained in the test with the Ditrich rod was significantly different between the country of origin of the participants.
Line 284-285, rephrase: The simple research tools of the Ditrich rod and hand grip dynamometer can still be very useful in the practice of sport, in particular in the fighting arts analysed here.
The conclusion needs some sort of summary statement to tie it all together. Perhaps expanding on the above sentence?
Newly added references need to be in consistent formatting with journal requirements.
