State-dependent radial elasticity of attached cross-bridges in single skinned fibres of rabbit psoas muscle

RESUMO
1. In a single skinned fibre of rabbit psoas muscle, upon attachment of cross-bridges to actin in the presence of ADP or pyrophosphate (PPi), the separation between the contractile filaments, as determined by equatorial X-ray diffraction, is found to decrease, suggesting that force is generated in the radial direction.
