Time- and Frequency-Domain Analysis of Stroke Volume Variability Using Indoor Cycling to Evaluate Physical Load of Body
Round 1
Reviewer 1 Report
The manuscript focuses on the investigation of the influence of intensive sporting activity on the potential myocardial injury. The topic is interesting but to my mind, the paper cannot be accessed in the present form due to the many incorrectness. Below, I present my remarks.
1. The English grammar is poor. There are many mistakes regarding the articles, structure of sentences, etc. Please, polish the English grammar in the manuscript.
2. It will be better to add the Related works section. The Introduction section should be reformatted in this case. This section should contain the actuality and importance of the solved task, current ways of this problem solving, the unsolved part of the general problem and the goal of the research. This information is absent in the manuscript.
3. Question to the equation 2. Function round, in my best opinion, should have two parameters. The second parameter indicates the specified number of digits. Please, explain this formula.
4. The quality of Figure 2,... is low. Please, improve them.
5. The equations (3) and (4) are the easiest normalised techniques. There are many other normalizing methods. Please, explain the reasons to use this method.
6. As I see, the charts in Fig.3 and 6 contains noise component. Did you consider this fact? Please, explain this.

Reviewer 2 Report
Thank you for giving me a chance to review this article. The authors have investigated the usefulness of SVV for predicting the physical load of the body. The authors have sequentially analyzed the data of this study and clarified reasonable results. Please check the following points.- Full spelling for abbreviations is required in every Table.
- μ is not suitable, if you used mean values and SDs, you should describe in 2.5.
- Fig.2 is not clear, please magnified view.
- Fig.6 is also unclear, same as No.3.
