Round 1
Reviewer 1 Report
I would like to express my gratitude regarding the opportunity to review this manuscript.
It is an interesting study, but at this stage the manuscript requires significant improvements. Below suggestions with page indication (please consider insert the lines in v2):
1 - Please consider instructions for authors and journal template (title in uppercases). Also, the template header presents 2021, please correct.

2 – Ref 9 before 8 – Please review.
2 – Please correct before “[13]”, also in page 3 before “[24]” and “[25]. Please carefully review all manuscript.
2 - The aim of the study should be clearly stated, and afterwards some hypothesis formulated.
2 – Please review, it seems more than one space before “men”.
2 - 2.4 – Any familiarization before intervention? What about conditions? Place, conditions (temperature, humidity). Time of day? Subjects’ routines and past experience? Nutrition? All that relates to intervention and data collection should be described in detail.
3 – “ADL” should be in full in the first appearance in the manuscript.
3 – Inclusion and exclusion criteria should be described in detail.
4 – Table 1 – In English is not “1º” but “1st”. Please correct in all cases.
5 – Figure 1 text font and size should be according to the journal template.
5 – In this page and in methods, all instruments’ procedures, and manufacturers information (with city and country) should be indicated.
6 – It Is suggested the written of the end paragraphs of “outcomes”.
6 – Please consider merging 2.6 and 2.7 and write the “statistical analysis” in detail.
7 – Please review figure 2 format and quality. For example, in subtitle “figure 2” repeated.
7-8 – Please review table 2 content and format.
9 – Table 3 – “a,b” and other examples. Readers should understand what represents (no reference in table).
10 – Please improve the quality of fig 3.
10-11 – Discussion section. Globally, the discussion section can be improved (for example “minimum age 60 and maximum 91” / “70% woman” / “Medication” / “Hospitalization” are topics to be addressed and some possible limitations). The deepening of the topic under study is very important. Also, some paragraphs with few text, contrary to others. Please consider standardization aiming providing readers better conditions for interpretations.
11 - Please consider developing the conclusions section with the main findings and clear and direct take-home messages.
12 – In “conflicts of interest” – Please remove “

Reviewer 2 Report
Our questions are associated to experimental design and statistics:
Because both groups belong to the same place, explain what mesaures were taken to avoid internal validity threats associated
Sample size is admited to be a limitation, consequently, statistical options must be in accordance:
- Shapiro-Wilk, instead of Kolmogorov-Smirnov must be used
- non-parametrics are more adequate
- if there is a data distribution tendentially normal, two-sided probability error must be considered
Because mainly biological data are compared, effect size r, instead o Cohen's d, should be applied
Because hypertension and psychiatric medication can affect ANS, vagal tone and barorreceptors, samples need to be characterized in these variables
Experimental group has pre-test with higher SpO2 and FVC (the last one with smaller SD), which may have affected enhanced capacity of this group to benefit with specific program, this is an internal validity threat and must be considered a limitation of the study
Figure 3 has a very relative interest, instead, we strongly suggest boxplots or line graphs (with SD), for pre post, with both groups, per dependent variable
Considering all previous observations, in "Discussion", first paragraph is considered somewhat speculative
We strongly recommend authors to:
- remake all statistics, and review discussion and conclusion according
- include all limitations, particularly those related with groups common origin
