Comparison of kurtosis and skewness parameters from fluorescence polarization fluctuation histograms of rigor and contracting skeletal myofibrils

Myofibrils	Skewness	Kurtosis	N
Rigor	−0.02 ± 0.04	0.06 ± 0.18	18
EDC-rigor	1.12 ± 0.34	0.84 ± 1.63	18∗
Relaxation	1.04 ± 0.19	0.20 ± 0.81	18
EDC-relaxation	1.48 ± 0.54	3.00 ± 3.05	18
Contraction	0.86 ± 0.16	−0.59 ± 0.27	18∗

Errors are given as SD, and N is the number of experiments.

^∗Two histograms with extreme maxima and minima were rejected.
