The ratio of the initial and final RMS amplitudes for relaxed muscle fibers. The total length of the oscillation was 20 seconds. All data points are (MEAN±SEM), and the number of fibers analyzed was N = 6. A one-sample t-test was used to test the null hypothesis that data collected at each frequency comes from a normal distribution with mean equal to 1. For data points marked with an asterisk, the null hypothesis was rejected (p<0.05).
