    HBS, be patient. Someone who is able to help will do so as soon as they can.

    Also, please do not post the same thing multiple times (I deleted your other posts).

    Explore MANOVA and see if it is a good fit.

    please calrify how MANOVA can be used in this case?

    In my case, unpaired t test give significant changes in say VO2max in a one group pre & post intervention case. i wan to see whether this significant change in VO2max (improvement) is due to significant increase in LBM(lean body mass) which also increase significantly after intervention. so i wan to test wether VO2max increase significantly after controlling for the increase in LBM.
