The moment arm length of the adductor magnus increases as hip flexion increases
from full hip extension to 90 degrees of hip flexion, being largest in at least 90 degrees of hip flexion (partial squat).

From there, drive through your heels to raise your

In this video, Carl continues with the Back

When sprinting, one the initial early acceleration phase has been completed, the joint angles of the
hip and knee during the ground contact phase range
from 30 degrees of flexion through to
full extension.
Test of transfer (long - term): Strength training that targets the
hip extensors close to
full extension (such as with the
hip thrust), and the knee extensors at around 40 degrees
from full extension (such as with the quarter squat), may well transfer better to sprinting than strength training that targets the
hip and knee extensors at other joint angles.
Németh & Ohlsén (1984) performed a study of 10 cadavers and 20 live subjects, and reported that the
hip extension moment arm length of the gluteus maximus moment arm of gluteus maximus decreased substantially
from around 8 cm to 3 cm with increasing
hip flexion angle, making the gluteus maximus far more effective as a
hip extensor in
full hip extension, than in
full hip flexion.
