Effect of low-level expression of α-MHC on time required to reach peak force

% α-MHC	Time Required to Reach Peak Force, ms	% Decrease in Time to Peak Force Compared with 0% α-MHC	Fold Decrease in Time to Peak Force Compared with 0% α-MHC
0	120.0		1
10	85.4	28.8	0.71
20	74.4	38.0	0.62
30	69.4	42.1	0.58

Data were obtained from model predictions of twitch time courses in myocardium with variable ratios of α-MHC and β-MHC. Fold decrease in time to peak force from 0% α-MHC was computed as the ratio of the time to peak force from 10%, 20%, and 30% α-MHC to 0% α-MHC.
