Implication

Muscle tension transients follow amplitude- and temperature-dependent exponentials; extends non-linear cross-bridge models in animals while leaving clinical translation open.

Structured PICO

P
Population
Small bundles of glycerinated fibres of rabbit psoas and insect fibrillar flight muscle
I
Intervention
Quick stretches and releases at various temperatures and amplitudes of length change
O
Outcome
Tension changes (tension transients)surrogate

The study characterizes the temperature and amplitude dependence of tension transients in skeletal and insect fibrillar muscle, supporting a non-linear model of cross-bridge attachment and detachment.
