During the weight acceptance phase of gait, the focus is on accepting the weight of the body as the foot strikes the ground and the knee begins to flex. The muscles involved play a critical role in stabilizing the ankle and controlling the movements of the foot and lower leg to ensure a smooth transition from the initial contact to loading the limb.

Dorsiflexors, which include muscles such as the tibialis anterior, are particularly active in controlling the foot's position as it comes into contact with the ground. They work eccentrically to prevent excessive plantar flexion, thereby allowing for a controlled lowering of the foot. The soleus and posterior tibialis contribute to maintaining balance and stability through their actions on the ankle, assisting in controlling the knee joint's flexion and extension.

While other muscles like the hip flexors and quadriceps are important at different phases of gait, they do not play as significant a role in the initial contact and weight acceptance as the dorsiflexors and the muscles mentioned. The gluteus maximus and hamstrings, for instance, are more involved in later phases where hip stability and extension are critical, especially during propulsion and swing phases.
