... of force, work and power. Here, we review how the comparative, realistic muscle physiology typified by Journal of Experimental Biology over the last 100 years has supported and refuted these theories. We examine variation in the contraction rates and force–length and force–velocity relationships predicted...

...Jonas Rubenson; Neville J. Pires; Heok O. Loi; Gavin J. Pinniger; Damian G. Shannon SUMMARY The region over which skeletal muscles operate on their force–length (F–L) relationship is fundamental to the mechanics, control and economy of movement. Yet surprisingly little experimental data exist...

...A. A. Biewener; C. McGowan; G. M. Card; R. V. Baudinette SUMMARY The goal of our study was to examine whether the in vivo force-length behavior, work and elastic energy savings of distal muscle-tendon units in the legs of tammar wallabies ( Macropus eugenii ) change during level versus incline...
