In practical terms, both upper and middle trapezius display high muscle activity at knee flexion angles of 31 — 60 degrees.

However, increases in muscle fascicle length are also likely dependent on the mechanical load incurred by the prime mover, as knee flexion (hamstring only) exercise seems to lead to greater adaptations in the hamstrings than hip extension (hamstring, gluteus maximus, and adductor magnus) exercise, even when muscle length at peak contraction is shorter (Bourne et al. 2016).

They're called hip flexors because they create flexion in the hip, which is the technical term for a bending movement around a joint in a limb that decreases the angle between the bones of the limb at the joint (such as the knee or elbow).
