Reviewer 1 Report
· Your article seems to be fine and original.
· Page 2, Lines 88: Please describe how was the sample size calculated?
· Page 3, Lines 116-118: Please clarify the point you are attempting to make. "Three measurements 116 were performed, with a five-minute interval".
· Page 4, Lines 157- 159: Provide a reference for this statement.
· Page 9, Lines 253-254: Please clarify the point you are attempting to make. "The most pointed explanation in the literature is related to changes in the energy balance".
· Page 9, Lines 267: Provide a reference for this statement. )Euklend et al.)
· The idea behind this work is good but discussion needs precision and clarity. Could you elaborate more on this by specifically talking about analyze the relationship between (MVPA), (SB), and cardiovascular risk factors between boys and girls.
