Abstract

• Clearly indicate the type of study (transversal, observational)
• Incorporate effect size or average differences between groups to provide clinical context

Introduction

• with high levels of sedentary behavior would demonstrate poorer balance and gait performance compared to those with lower sedentary behavior, regardless of their physical activity levels. 
• Although it is mentioned that "PA may not compensate for the effects of SB", it is not developed because physiologically this occurs (for example, metabolic, vascular or neuromuscular mechanisms)
• It is alluded to the fact that the PA improves both, but it is not explained how the SB could deteriorate them.
• The sample size (n=133) is not justified nor was a previous power analysis performed
• The time of day, footwear used, or control of external factors (fatigue, caffeine, sleep), which can influence balance and gait, are not described. It is also not detailed whether practice or familiarization trials were carried out before the test.

Discussion

• Some paragraphs are very long and redundant. For example, sections 4.1 and 4.2 repeat the idea that physical activity partially compensates for a sedentary lifestyle. This could be summarized to improve clarity and avoid unnecessary repetition
• The APA analysis could delve into the clinical relevance of longer versus shorter duration, since the discussion mentions advantages and disadvantages, but does not contextualize whether the differences found are functionally significant
• Extrapolation to older populations is reasonable, but it should be more cautious, since the data comes exclusively from healthy young adults
• The repetition of terms such as "sedentary active" and "physically active" can make it difficult to read; consider using clear acronyms or consistent abbreviations
