Implication

Animal data on bladder smooth muscle should not yet change practice; leaves open cross-bridge kinetics for human validation.

Structured PICO

P
Population
AC-stimulated smooth muscle strips from rabbit urinary bladder
I
Intervention
Isotonic quick release (force step) at different temperatures (37°C and 27°C) and tension levels
O
Outcome
Length response to a force step (elastic recoil, rapid length change, steady length change)surrogate

The length response of rabbit urinary bladder smooth muscle to a force step involves three distinct phases, suggesting specific cross-bridge dynamics during contraction and relaxation.
