H89, a non-specific PKA inhibitor, decreases contractile but not relaxation kinetics. Developed tension (A), time to peak tension (B), time from peak tension to 50% relaxation (C), and time from peak tension to 90% relaxation (D) before and after application of H-89, a PKA inhibitor, at taut and optimal muscle lengths. Data collected at 1 Hz, 37 °C, n = 23.
