Author's response to reviews Title: Effect of standing posture during whole body vibration training on muscle morphology and function in older adults: a randomised controlled trial Authors:

Can remove the sentence ?We report interim 3 month measures? from the methods section There is a comma needed after 3.7cm2 in the results These have been done Background Paragraph 7 ? continual references to bone should be removed since the current study is focused on physical activity and muscle morphology (ln 2, 3, 4, 6, 8, 12-13) This has been done Methods Pg 9 ? last line there are two periods Pg 10 paragraph 2 ? this section could be moved up and be incorporated into the WBV intervention section The additional period has been removed. The section has been moved as suggested Results Pg 15 paragraph 1 ? can remove the words ?this interim? from the second last line of the recruitment paragraph so the line reads ?One participant had not completed three months of exposure by the time of analysis (FK=1) and was not included in this report.? Pg 17 paragraph 1 the last line talking about no changes in peak power refers to Table 3, should this not be referring to table 4 that demonstrates the interventions had no effect on peak muscle power? These have been done Discussion Pg 19 paragraph 2 ? the first sentence should say ?after 3 months? instead of ?at 3 months? This has been done Table 1 ? the WBV and unlocked knees sentences can be removed as they are not in the table This has been done Level of interest An article of importance in its field Quality of written English Acceptable Statistical review No, the manuscript does not need to be seen by a statistician.

I believe it is now much improved. I have only one small comment. You should consider removing the last sentence in the 'Methods' paragraph of the Abstract. Then in the 2nd sentence of that same paragraph, end with "...for 13 weeks". These have been done Level of interest An article of importance in its field Quality of written English Acceptable Statistical review No, the manuscript does not need to be seen by a statistician.
