Reviewer #1: Abstract:

Fourteen elite female field

30 hockey players (eight of them international-level standard)

- what level was the rest of the athletes?

"During four high-level competitive matches "

what does this mean? What is the level of competition (national? intra squad? international?

Intro:

Step frequency also

37 demonstrated very large associations with sprint, sprint·min⁻¹, HSR·min⁻¹, and maximal

38 acceleration

- please provide data to support "very large"

The relationship

73 between these factors and performance has been reported in the case of SF, and it may be

74 affected differently by fatigue and competitive level [22,23].

- this sentence could use more information on the relationships between factors - is it inverse? positive? how is it affected by fatigue and comp level?

GPS-derived physical performance metrics during elite

83 female field hockey matches.

- Which GPS metrics?

Materials and methods:

96 Participants

97 Fourteen elite female hockey players (age 25.40 ± 4.48 years, height 1.68 ± 0.04 m and

98 body weight 58.53 ± 2.56 kg), including eight international-level players participated in

99 this study.

- What was the level of the remaining players?

Were they analyzed or grouped by position? this would be an important factor to include in game data. This is a major limitation.

During these matches, the average number of

114 goals scored by the studied team was 2.5 compared with 4.8 during the regular league

115 season. Goals conceded averaged 0.75 against top-four teams and 0.60 against lower 116 ranked teams.

- This feels random here. Maybe more context needed? Is this indicating the context of the games played?

Were all players played in every game? was just active time on pitch included in analysis?

Table 1-4 - Horizontal lines between rows would improve readability

276 DISCUSSION

277 Firstly, in line with the secondary aim, the use of averaged match data across four games

278 with similar ranking teams proved to be a valid and reliable approach,

I think language coul dbe softened here, it does not necessarily prove antying, but is just 4 games so may suggest rather than prove

Practical applications like step frequency above 4hz and decrements below 4% feel like they are overstretching what the paper actually shows.

I think it is also important to acknowledge small sample size and use of correlational analyses in the limitaitons, and with any interpretations.

Reviewer #2: Overall comments:

This manuscript examines the associations between repeated sprint ability (RSA) kinematic variables and locomotor activity in elite female field hockey players. The topic is relevant, and integrating RSA kinematics with GPS derived match metrics has the potential to contribute meaningfully to applied practice. The manuscript is generally well structured, and the rationale is clearly articulated. However, several important methodological and statistical details are missing, which limits confidence in the robustness of the findings.

The statistical analysis, in particular, requires greater methodological rigour. The manuscript does not justify the sample size or specify the variable on which the study was powered, and confidence intervals are not provided for key estimates. The reliance on simple correlations limits the ability to account for confounding factors or the repeated measures structure of the data. Mixed effects models or multivariable regression approaches could provide more robust insights by modelling within player variability and controlling for covariates. Addressing these issues would substantially strengthen the statistical validity and interpretability of the findings.

Title: Consider whether “match performance” is appropriate; the study examines locomotor activity, not performance outcomes.

Short title: Similarly, “match demands” is misleading. GPS/accelerometer data reflect activity profiles, not the true “demands” of match situations.

Abstract: Replace “physical performance” with “GPS‑derived locomotor activity.”

L42: Fatigue development was not assessed; this claim should be removed.

L49 – linking GPS to match outcomes is inappropriate. Greater locomotor activity may be a consequence of the standard of opponent and does not determine the ‘outcome’ (match result), as the sentence currently implies. See James et al. (2023). Relationships between opponent ranking and locomotor activity in international field hockey. International Journal of Sports Science & Coaching, 18(6), 2070-2081.

Feels like first paragraph is mostly redundant, given the number of preceding hockey GPS papers. I think the authors could probably start at Paragraph 2.

L62 – 66. Suggest to attach the specific citation to each of these points about opponent / playing style / match importance. Environmental conditions are another modifying factor here, for example see James et al. (2022). Increased air temperature decreases high-speed, but not total distance, in international field hockey. Temperature, 9(4), 357–372.

L71 – 73 – the importance of kinematic factors is not explained. Authors may wish to expand on this. Why is it important to understand? Does it guide training prescription?

L78 – Clarify what is meant by “improving the ecological validity of RSA testing.” Are you implying RSA protocols should be modified based on these correlations?

L83 – ‘As a preliminary step’ not needed

L85 – why were four matches selected?

L85 – do you mean absolute total meters or intensity? (per min?). This is important to distinguish because you cannot control the playing time of the players.

L90 – what is similarly ranked?

L91 – stability is inappropriate term for describing variability

L92 – this is not competitive performance, but locomotor activity.

L98 – Consider using the McKay et al. performance‑calibre framework to contextualise your players. doi:0.1123/ijspp.2021-0451

L122 – 130 – Was maximal sprint speed (MSS) verified? How do you know players did not pace the first sprint? Can you compare RSA velocities with historical or match‑derived peak speeds?

The description of step frequency and step length calculations is clear, but more detail is needed regarding the reliability of the video based method (e.g., intra and inter rater reliability, number of steps analysed, automated or manual digitisation).

L150 – please provide citation for use of predetermined speed thresholds. What are peak sprinting speeds for this group and does HSR actually represent high-speed for these individuals?

Statistical approach - The manuscript does not provide any justification for the sample size (n = 14), nor does it specify which variable or effect the study was powered to detect.

Can you justify that 4 matches is sufficient beyond that you didn’t find a statistical difference between matches? Also, did all 14 players play all matches?

Correlations are presented as “very large,” but the manuscript should include confidence intervals for correlation coefficients to report uncertainty. Additionally, the authors should clarify whether assumptions (normality, outliers) were checked.

Given the repeated measures structure (multiple matches nested within players), mixed effects models would provide a more statistically rigorous framework. Such models account for:

• Repeated measures,

• Incorporate relevant contextual covariates (e.g., position, playing time, opponent ranking), and

• estimate individual slopes linking RSA metrics to match performance.

Similarly, multivariable regression could help determine the independent contribution of sprint velocity, step frequency, and step length while controlling for shared variance. This would provide a more nuanced understanding of which RSA determinants truly predict match demands.

Table 1 – 2 decimal places is not necessary. Consider the reported accuracy of such systems when choosing the level of precision to report (e.g. 0 d.p. should be sufficient here for most variables aside of accel metrics).

There is no such thing as TD.min or relative distance. This is an average speed. Average speed is typically expressed as m.min in training contexts and the literature.

A lot of values in these tables. Did you consider a multi-panel plot showing match values and you could have a dashed line through the middle of each to represent the average?

L236 – “Average match demands and SL during the RSA test did not show any significant (p < 0.05) relationship (Table 3).” This p value is significant.

Table 3 – commas instead of decimals throughout this table.

L280 – arguably the statistical significance is not the primary consideration here, probably more so the “clinical’ meaningfulness of those measures. See larger datasets for typical variability of international players e.g >70 matches. doi: 10.3389/fspor.2021.653364

L292, suggest to discuss aim 1 first and then the variability analysis which was secondary.

L314 – no discussion of how data were processed – ball in play time only? What did you do for PCs and after goals scored. This artificially skews intensity metrics.

The discussion would benefit from acknowledging that RSA testing captures linear sprinting, whereas match demands include curved runs and directional changes.

The conclusion that RSA velocity and step frequency are “closely linked” to match performance should be tempered. Correlational data cannot establish predictive validity or causality.

Revision 1

We thank the editor and reviewers for their valuable comments and suggestions, which have helped us to improve the quality of the manuscript. A detailed, point-by-point response to all reviewer and editor comments has been provided in the attached document ("Response to Reviewers").

For completeness, and as requested, we also reproduce our responses in the box below.

Reviewer #1:

We would like to thank the reviewer for the careful reading of our manuscript and for the constructive and valuable comments provided. We greatly appreciate the detailed feedback, which has helped us improve the clarity, precision, and overall quality of the manuscript.

In response to the reviewer’s suggestions, we have revised the manuscript to clarify key aspects of the sample description and competitive context, improve the reporting of variables and methodological procedures, and refine the wording in several sections to ensure greater accuracy and consistency. We have also expanded specific parts of the Introduction and Methods to better support the rationale and interpretation of the findings, and we have tempered certain statements in the Discussion and practical applications to better reflect the scope and limitations of the study. All changes have been carefully addressed and are detailed in the point-by-point responses below.

Abstract:

Fourteen elite female field

30 hockey players (eight of them international-level standard)

- what level was the rest of the athletes?

All players included in the study belonged to the same first team, which competes at the highest national and European level (Spanish national champions and European runners-up). The distinction made in the original version aimed to highlight that eight players were also members of the Spanish national team. However, we agree that this may have created ambiguity regarding the level of the remaining players. This has been clarified in the revised manuscript by revising the sample description in both the Abstract and Methods sections.

"During four high-level competitive matches "

what does this mean? What is the level of competition (national? intra squad? international?

We agree that the term “high-level competitive matches” was not sufficiently specific. The manuscript has been revised to clearly define the level of competition by specifying that the matches were official competitive fixtures played against top-level opponents (i.e., teams ranked in the top four of the national league or National Cup semi-finalists).

Intro:

Step frequency also

37 demonstrated very large associations with sprint, sprint·min⁻¹, HSR·min⁻¹, and maximal

38 acceleration

- please provide data to support "very large"

The correlation coefficients (r) and associated p-values have now been included in the revised manuscript to substantiate these statements.

The relationship

73 between these factors and performance has been reported in the case of SF, and it may be

74 affected differently by fatigue and competitive level [22,23].

- this sentence could use more information on the relationships between factors - is it inverse? positive? how is it affected by fatigue and comp level?

We agree that the original sentence lacked specificity regarding the nature of the relationships described. The text has been revised to clarify the direction of the relationship between step frequency (SF) and performance in the context of fatigue, as well as its modulation by competitive level.

GPS-derived physical performance metrics during elite

83 female field hockey matches.

- Which GPS metrics?

We have clarified the GPS-derived metrics by including representative examples (total distance, high-speed running, sprint distance, accelerations and decelerations, and maximum speed) in the Introduction, while avoiding excessive methodological detail.

Materials and methods:

96 Participants

97 Fourteen elite female hockey players (age 25.40 ± 4.48 years, height 1.68 ± 0.04 m and

98 body weight 58.53 ± 2.56 kg), including eight international-level players participated in

99 this study.

- What was the level of the remaining players?

We clarified the competitive level of the participants by specifying that all players belonged to the same first team, which were Spanish national champions and European runners-up. This contextual information reflects the elite level of all participants. Additionally, we specified that eight players were members of the Spanish national team.

Were they analyzed or grouped by position? this would be an important factor to include in game data. This is a major limitation.

Players were not grouped or analyzed according to playing position. This was due to the inclusion criterion requiring players to participate in all analyzed matches, which reduced the sample size from the original squad due to illness-related absences. In addition, some players performed different positional roles across matches, making positional classification inconsistent. For these reasons, and to avoid excessive model complexity given the number of variables analyzed, positional analysis was not performed. This aspect has now been acknowledged as a limitation in the revised manuscript.

During these matches, the average number of

114 goals scored by the studied team was 2.5 compared with 4.8 during the regular league

115 season. Goals conceded averaged 0.75 against top-four teams and 0.60 against lower 116 ranked teams.

- This feels random here. Maybe more context needed? Is this indicating the context of the games played?

We have clarified the context of the analyzed matches by specifying that they were played against top-ranked teams, representing higher competitive demands compared to regular league fixtures. To better support this, we included match outcome indicators (goals scored and conceded), which reflect the increased difficulty of these matches. Additionally, we clarified that all matches were performed within a three-week period following RSA testing, which can be considered sufficiently short to assume a relatively stable fitness status of the players.

Were all players played in every game? was just active time on pitch included in analysis?

We have clarified in the Participants section that only players who participated in all analysed matches were included in the study, which explains why the final sample did not include the entire squad. Additionally, we have specified in the GPS data section that relative variables were calculated based on the total time spent on the field during matches.

Table 1-4 - Horizontal lines between rows would improve readability

Horizontal lines between rows have been added to Tables 1–4 to improve readability, and we hope this facilitates clearer interpretation of the data.

276 DISCUSSION

277 Firstly, in line with the secondary aim, the use of averaged match data across four games with similar ranking teams proved to be a valid and reliable approach,

I think language coul dbe softened here, it does not necessarily prove antying, but is just 4 games so may suggest rather than prove

The language has been revised to adopt a more cautious tone, replacing definitive statements with more appropriate expressions

Practical applications like step frequency above 4hz and decrements below 4% feel like they are overstretching what the paper actually shows.

I think it is also important to acknowledge small sample size and use of correlational analyses in the limitaitons, and with any interpretations.

We agree that the proposed practical thresholds (e.g., step frequency > 4 Hz and performance decrements < 4%) should be interpreted with caution. These values were derived based on the mean step frequency observed in the present study and are supported by the magnitude of step frequency decrements reported in previous literature [22,23], where reductions of approximately 3–4% during RSA have been described. To address this concern, the text has been revised to present these values as tentative reference points rather than definitive thresholds.

Additionally, as suggested, we have explicitly acknowledged in the limitations section the relatively small sample size and the correlational nature of the analysis, emphasizing that the findings do not imply causality and should be interpreted with caution.

Reviewer #2:

Overall comments:

This manuscript examines the associations between repeated sprint ability (RSA) kinematic variables and locomotor activity in elite female field hockey players. The topic is relevant, and integrating RSA kinematics with GPS derived match metrics has the potential to contribute meaningfully to applied practice. The manuscript is generally well structured, and the rationale is clearly articulated. However, several important methodological and statistical details are missing, which limits confidence in the robustness of the findings.

The statistical analysis, in particular, requires greater methodological rigour. The manuscript does not justify the sample size or specify the variable on which the study was powered, and confidence intervals are not provided for key estimates. The reliance on simple correlations limits the ability to account for confounding factors or the repeated measures structure of the data. Mixed effects models or multivariable regression approaches could provide more robust insights by modelling within player variability and controlling for covariates. Addressing these issues would substantially strengthen the statistical validity and interpretability of the findings.

We would like to sincerely thank the reviewer for the thorough and insightful evaluation of our manuscript. We greatly appreciate the time and effort invested in providing such a detailed and constructive review. The comments have been extremely valuable in helping us improve the methodological clarity, statistical transparency, and overall interpretability of the study.

In response to these suggestions, we have carefully revised the manuscript, addressing all the points raised. Substantial improvements have been made, including clarification of methodological procedures, refinement of statistical reporting (e.g., inclusion of confidence intervals and assumptions checking), adjustments in terminology to ensure conceptual accuracy, and a more cautious interpretation of the findings in line with the correlational nature of the data. We have also incorporated additional references, expanded relevant sections of the Introduction and Methods, and explicitly acknowledged key limitations of the study. All changes are described in detail in the point-by-point responses provided below.

Title: Consider whether “match performance” is appropriate; the study examines locomotor activity, not performance outcomes.

We agree that the term “match performance” may be misleading, as the study specifically examines locomotor activity rather than direct performance outcomes. Accordingly, we have revised the title to better reflect the nature of the variables analyzed. We believe this change improves the accuracy and clarity of the manuscript.

Short title: Similarly, “match demands” is misleading. GPS/accelerometer data reflect activity profiles, not the true “demands” of match situations.

The short title has been revised to better reflect the nature of the variables analyzed.

Abstract: Replace “physical performance” with “GPS derived locomotor activity.”

Revised as suggested: ‘physical performance’ has been replaced with ‘GPS-derived locomotor activity’ in the Abstract.

L42: Fatigue development was not assessed; this claim should be removed.

The statement has been revised to remove any implication of fatigue assessment. The sentence now refers to the prediction of GPS-derived locomotor activity during competitive matches.

L49 – linking GPS to match outcomes is inappropriate. Greater locomotor activity may be a consequence of the standard of opponent and does not determine the ‘outcome’ (match result), as the sentence currently implies. See James et al. (2023). Relationships between opponent ranking and locomotor activity in international field hockey. International Journal of Sports Science & Coaching, 18(6), 2070-2081.

Feels like first paragraph is mostly redundant, given the number of preceding hockey GPS papers. I think the authors could probably start at Paragraph 2.

We agree that linking locomotor activity directly to match outcomes may be inappropriate, as match results are influenced by multiple contextual factors. Accordingly, the sentence has been revised to remove any implication of a direct relationship with match outcomes. In addition, the introductory paragraph has been streamlined to reduce redundancy and improve clarity.

L62 – 66. Suggest to attach the specific citation to each of these points about opponent / playing style / match importance. Environmental conditions are another modifying factor here, for example see James et al. (2022). Increased air temperature decreases high-speed, but not total distance, in international field hockey. Temperature, 9(4), 357–372.

We have revised the sentence to associate each contextual factor with specific references and have incorporated environmental conditions, including air temperature, as an additional factor influencing locomotor activity, as recommended.

L71 – 73 – the importance of kinematic factors is not explained. Authors may wish to expand on this. Why is it important to understand? Does it guide training prescription?

We thank the reviewer for this comment. We agree that the importance of kinematic factors was not sufficiently explained. The text has been revised to clarify their relevance by highlighting that sprint velocity is determined by the interaction between step length and step frequency (V = SL × SF), and that their analysis provides additional insight into the mechanisms of performance and fatigue, which may help to inform training prescription.

L78 – Clarify what is meant by “improving the ecological validity of RSA testing.” Are you implying RSA protocols should be modified based on these correlations?

The term ‘ecological validity’ has been replaced to better reflect the practical relevance of RSA testing in relation to GPS-derived locomotor activity.

L83 – ‘As a preliminary step’ not needed

The wording has been revised to remove ‘preliminary step’ and clarify the role of this analysis in supporting the use of averaged match data. For this reason, the results of the secondary aim are presented first in the Results section, as they provide the basis for the subsequent correlational analyses between match averages and RSA performance.

L85 – why were four matches selected?

The four matches were selected to ensure consistency with the RSA testing context and to include matches against top-ranked opponents, thereby reducing variability related to competitive level. This selection criterion is now clarified in the Methods section.

L85 – do you mean absolute total meters or intensity? (per min?). This is important to distinguish because you cannot control the playing time of the players.

As indicated in the Methods section, both absolute values and relative values normalized to individual playing time were included in the analysis.

L90 – what is similarly ranked?

The term ‘similarly ranked’ has been clarified. The analyzed team consistently ranked first or second in the national league over the past 10 years, and comparisons were made against teams occupying top positions in the league standings or reaching the semi-finals of the National Cup. This information has been clarified in the Methods section.

L91 – stability is inappropriate term for describing variability

The term ‘stability’ has been revised to ‘low match-to-match variability’ to more accurately describe the consistency of the measured variables.

L92 – this is not competitive performance, but locomotor activity.

The term ‘competitive performance’ has been replaced with ‘locomotor activity’ throughout the manuscript to ensure terminological accuracy.

L98 – Consider using the McKay et al. performance calibre framework to contextualise your players. doi:0.1123/ijspp.2021-0451

The performance calibre framework proposed by McKay et al. has been incorporated into the manuscript. Players were classified a

Reviewer #1: Thanks to the authors for the detailed revisions and responses to the reviewer comments. The manuscript has improved in clarity, contextual detail, and interpretation of the findings.

I appreciate the more cautious framing of the correlational findings and practical applications, along with the added acknowledgment of limitations related to the sample size, positional analysis, and study design.

I still think the small sample size and correlational/statistical approach should be considered when interpreting the findings and practical implications, and I think the overall contribution of the paper remains relatively modest. However, I think the authors have addressed the major concerns appropriately within the scope of the dataset, and I have no further major concerns.

Reviewer #2: Well done on making considerable changes. I think the manuscript is much better positioned bow, especially as many limitations are transparently reported.

The only minor comment i would make to the authors is to encourage them to again reconsider the use of 'relative distance' - just because other research has published this, is not a rationale to use scientifically incorrect terminology. Distance is not being normalized to some factor, it is simply divided by time, which provides speed.

Revision 2

Reviewer #1:

Thanks to the authors for the detailed revisions and responses to the reviewer comments. The manuscript has improved in clarity, contextual detail, and interpretation of the findings.

I appreciate the more cautious framing of the correlational findings and practical applications, along with the added acknowledgment of limitations related to the sample size, positional analysis, and study design.

I still think the small sample size and correlational/statistical approach should be considered when interpreting the findings and practical implications, and I think the overall contribution of the paper remains relatively modest. However, I think the authors have addressed the major concerns appropriately within the scope of the dataset, and I have no further major concerns.

We sincerely thank the reviewer for the positive evaluation of the revised manuscript and for acknowledging the substantial improvements in clarity, contextualization, interpretation, and reporting of limitations. We appreciate the reviewer’s constructive feedback throughout the review process, which has contributed significantly to improving the quality of the manuscript.

Reviewer #2:

Well done on making considerable changes. I think the manuscript is much better positioned bow, especially as many limitations are transparently reported.

The only minor comment i would make to the authors is to encourage them to again reconsider the use of 'relative distance' - just because other research has published this, is not a rationale to use scientifically incorrect terminology. Distance is not being normalized to some factor, it is simply divided by time, which provides speed.

Thank you for this insightful comment and for the positive evaluation of the revised manuscript. We agree that the term “relative distance” may be conceptually imprecise, as the variable reflects distance covered per unit of time and therefore represents an average speed measure rather than a normalized distance metric. Accordingly, the terminology has been revised throughout the manuscript by replacing “total distance per minute” and its abbreviation “TD·min⁻¹” with “average speed” and “Avg speed”, respectively, to improve conceptual and scientific accuracy.
