Fig. 5. Examples of the Ca²⁺ concentration/tension relationship measured from different skinned muscle fiber preparations. Tension is expressed as a percentage of maximum tension. (A) Muscle fibers with different Ca²⁺ sensitivity (pCa₅₀) and similar Hill coefficients (n_H). (B) Muscle fibers with similar Ca²⁺ sensitivity but different Hill coefficients.
