Requires thinner preparations to minimize diffusion limits; leaves open optimal dimensions for reliable isolated muscle experiments.
The study demonstrates an inverse relationship between tension development and muscle thickness in isolated rat cardiac muscle, highlighting the limitations of isolated muscle preparations due to oxygen diffusion constraints.
Frezza et al. (1976) studied this question.
