The percent decline in peak force between pre-fatigue and post-fatigue 60 Hz testing trains (a) and the pre- and post-fatigue 20 Hz:60 Hz peak force ratios (b) for the three fatigue protocols tested. There were significant differences between the pre- and post-fatigue 20 Hz:60 Hz peak force ratios for each of the three fatigue protocols (p < 0.01). *Significant differences between protocols (p ≤ 0.05).
