... for individual and simultaneous muscle activation could be explained without an associated change in the force potential of the muscles between the two conditions. A basic assumption typically made in muscle mechanics is that muscle properties determined for an individual muscle remain the same when...

... for the flexor. Resting extensor tibiae muscle passive tonic force increased from 2 to 5 mN in the maximum femur–tibia (FT)-joint working range when stretched by ramps. Active muscle properties were measured with simultaneous activation (up to 200 pulses s –1 ) of all three motoneurons innervating the extensor...

... inhibited the maturation of these muscle properties, whereas injection of JH into precocene-treated females reversed this effect. Homologous muscles from the third abdominal segment (a non-oviposition segment, M169) and muscles from males (M214) revealed no comparable changes, although some minor changes...
