Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe study presents an original and interesting investigation evaluating the efficacy of HIIT on body composition and physical performance in trained young adults. The research focuses on the effects of different recovery strategies—active recovery and passive recovery—during an 8-week HIIT program involving running and whole-body exercises. The results demonstrate that HIIT reduced body fat, increased fat-free mass, and improved oxygen consumption, with females showing better adaptations in lower limb muscle area and vertical jump performance, while males excelled in agility, demonstrating its effectiveness for both sexes.
The study requires minimal improvements before publication:
1. Ensure that the keywords are sorted alphabetically.
2. Please standardize the use of spaces between mathematical symbols throughout the manuscript, under scientific notation guidelines.
3. Please specify HGS (handgrip strength) and CMJ (countermovement jump) in the abstract or text, as their meanings are not clear from the context.

Reviewer 2 Report
Comments and Suggestions for AuthorsI want to thank the authors for their article.
Below are some minor suggestions:
- Please add any data regarding the reliability of the Body Composition, HGS, Power, Agility, and Peak Oxygen Consumption methods used in healthy and unhealthy males and females.
- In the participants' section, I suggest authors add a consort diagram.
- HGS is not just Strenght, but HandGrip Strenght. Please revise the whole text.

I want to thank the authors for their article.
A: We would like to thank you for your useful comments.

A: Dear reviewer, thank you for your comment. We hope to understand the meaning of your request, and we apported some improvements. As you can see in the methods section, we added the TEM (technical error of measurements) for longitudinal reliability, while the intra-class correlation (ICC) and concordance correlation coefficient (CCC) had already been reported. All these measures refer to our data and investigation; if you however prefer to evaluate previous results, you can use the reference reported. The manuscript explains much information and we cannot add details of previous validation, especially in irrelevant targets such as unhealthy adults.
R: In the participants' section, I suggest authors add a consort diagram.
A: We added the Consort Diagram as you suggested.
R: HGS is not just Strenght, but HandGrip Strenght. Please revise the whole text.
A: We improved the whole text as you suggested
