Population

Six anesthetized cats (soleus muscle)

Comparison

Stimulation of ventral root bundles during… vs Partial versus whole muscle activation

Design

Preclinical

Authors

Discussion

Animal data on feline muscle mechanics; leaves open any relevance to human cardiac or skeletal force dynamics.

Population

Six anesthetized cats (soleus muscle)

Intervention

Stimulation of ventral root bundles (alone or together) during isometric and ramp movements

Comparator

Partial versus whole muscle activation

Outcome

Nonlinear summation of force (F(nl))surrogate

In cat soleus muscle, nonlinear summation of force is small and primarily results from the stretch of common-elastic elements.

Thomas G. Sandercock (2000) studied this question.
