Figure 4. Mass-normalized recruitment threshold range for MUs identified in the vastus medialis and vastus lateralis during the 70% and 100% trials.

Individual circles depict the predicted value from the mixed effect model. Solid horizontal bars represent the least squared means and vertical error bars are the standard deviation. Post hoc comparisons that reached statistical significance are denoted with brackets. ACLR, anterior cruciate ligament reconstruction; MVIC, maximum voluntary isometric contraction; Nm/kg, Newton-meter per kilogram.
