Steadiness of submaximal contractions during the fatiguing task. Steadiness of submaximal contractions performed during the intermittent isometric trunk flexion fatiguing protocol. Standard deviation (SD) of torque (a) and coefficient of variation (CV) of torque (b) are shown as the mean ± SEM of three submaximal contractions at each quartile (beginning, 25%, 50%, 75%, and end) of the total time-to-task failure. Fluctuations in torque increase over time for both males and females (p < 0.05) with no sex difference in steadiness between males and females
