Reviewer: Marta Van Loan  
 
Reviewer's report:  
 
Authors have made appropr iate corrections based on earlier review. However, there are still 
some additional edits that are needed. These are outlined blow.  
Some reference are not cited in the text; specifically reference 3, 7, and 8 do not appear in the 
Background. Additionally, references 6 is out of order . I appears on line 14 prior to references 4 
and 5.  Please double check that all references are cited in the text and in the proper order.  
Background Page 1 Line 54:  What is bone mass power?  Do you mean that physical activi ty is 
important to the development and maintenance of bone mass and density?  
Methods line 44:  What do you mean when you say: "subjects only had daily physical activity? 
Do you intend to indicate some form of physical exercise or that subject only did ac tivities 
related to daily living that may include house cleaning, grocery shopping, laundry etc., but not 
specifically games/sports and other forms of physical activity.  
Methods Line 54:  "taking into account the fifth day of the monthly period..."   I do n't understand 
this statement.  Do you mean the fifth day of the menstrual cycle? Was the start of training 
adjusted for each woman's menstrual cycle? If so, this needs to be clarified.  This express appears  
again on line 57 of Blood analysis. Were pre - and post - intervention blood samples run together 
on the same plate.  Please be specific in the Methods section on this detail.  
Measurement of BMD line 18.  Do you mean that osteoporosis was defined on bone mass T -
scores or BMD T -scores.  Please correct as appropriate.  
Discussion line 39: the correct expression is ground reaction force not "earth."  
Discussion line 51.  Bone morphogenetic proteins should have a lower case b to match with the 
"m" and "p" of morphogenic and protein.  
Discussion Page 2 line 15:  "elderlies" should be elderly.  
Discussion Page 2 line 21:  What do you man by "rare elements?"  
Reference 1: journal abbreviation should be in upper case.  J Bone Min Metabol
