What's the difference between traditional hard maps and sumo hard maps?

Traditional hard painting and sumo hard painting are two different hard painting methods, and they have certain differences. On the surface, the traditional hard pull station distance is narrow, and the initial hip position is relatively high, while the sumo hard pull station distance is relatively wide, the initial hip position is relatively low and the trunk is more vertical.

The researchers found that the traditional hard pull will bring more shear force to the back, especially in L4 and L5. In addition, the traditional hard drawing has higher requirements for extensor dorsi, hamstring and gastrocnemius. On the other hand, the hard pull of sumo gives greater stimulation to the medial thigh muscle, lateral thigh muscle and tibialis anterior. On the contrary, compared with the lateral thigh muscle, the medial thigh muscle stimulates the rectus femoris relatively less. This is because rectus femoris is a double joint muscle, which can not only stretch the knee, but also participate in hip flexion.
