Figure 6. CK‐2066260 increases force in submaximal contractions in single mouse FDB fibres at 31°C without affecting [Ca²⁺]_i .

A, typical data of [Ca²⁺]_i and force during 30 Hz contractions of a single fibre (A) before (black line) and after 5 min exposure to 10 μm CK‐2066260 (red line). B, mean data (±SEM) of [Ca²⁺]_i and force during exposure to CK‐2066260: open circles, 5 μm (n = 3); filled circles, 10 μm (n = 4).
