Prevention of disuse muscle atrophy

My research focuses on the effects of intermittent weight-bearing or stretching to prevent the progression of disuse muscle atrophy. In experiments using an animal (rat) model of hindlimb suspension, I have been conducting the following analyses:
1) Morphometric analyses (muscle length, circumference, ROM of joint)
2) Physiological analyses (contractile properties; twitch tension, etc. in vitro)
3) Biochemical analyses (protein concentrations; myofibrillar protein, etc.)
4) Histological analyses (HE staining)
5) Histochemical analyses (ATPase staining; classification of muscle fiber type)
6) Immuno-cytochemical analyses (labeling of BrdU, TUNEL, etc.)
