Important calculations for the energy values of gastrocnemius lateralis (GL) in the mid-low frequency band (d3), as well as rectus femoris (RF) in the high frequency band (d1), are presented for different groups at various knee starting angles (mean ± SD) (n = 13).

The effect sizes of 90° and 120° relative to 60° are reported in square brackets. The two-way ANOVA results (A: angle effects, P- and F- value) are shown in the right column.
