Key result
An ionic-chemical-mechanical model based on polyelectrolyte theory suggests actin-myosin electrostatic interactions generate forces in the pN range during the intermediate stages of muscle contraction.
This theoretical model suggests that actin-myosin electrostatic interactions play a significant role in the intermediate stages of binding during muscle contraction, generating forces in the pN range.

Offers a polyelectrolyte framework for contraction forces; leaves open validation in cardiac models.
Gerald S. Manning (2016) studied Muscle contraction. Ionic-chemical-mechanical model was evaluated on Electrostatic force estimates. An ionic-chemical-mechanical model based on polyelectrolyte theory suggests actin-myosin electrostatic interactions generate forces in the pN range during the intermediate stages of muscle contraction.
