...Claire L. Harwood; Iain S. Young; John D. Altringham ABSTRACT This study investigates the effects of cycle frequency, strain and length on work and power output of isolated rainbow trout ( Oncorhynchus mykiss ) ventricular preparations using the work loop technique. These effects are discussed...

..., such as the length–force relationship and the kinetics of activation and deactivation (relaxation). We examined the effects of relative shortening velocity on the maximum net power output (over the entire cycle) of mouse soleus muscle, using sawtooth strain trajectories over a range of cycle frequencies. The strain...

...Douglas A. Syme; Robert K. Josephson ABSTRACT The work capacity of segments of atrial and ventricular muscle from the frog Rana pipiens was measured as a function of muscle length using the work loop technique. Both the work done during shortening and the work required to re-lengthen the muscle...

...A. C. Guimaraes; W. Herzog; M. Hulliger; Y. T. Zhang; S. Day ABSTRACT The effects of changing the length of the cat soleus muscle on electromyographic (EMG) signals, muscle force and the corresponding EMG–force relationship were assessed using distributed stimulation of ten ventral root filaments...
