The triple-extension in the snatch ( simultaneous extension of the knee and hip, and plantar flexion at the ankle ) mimics the movements previously mentioned while requiring the athlete to produce large amounts of power at high velocities.

His name is associated with the eponymous " Remak reflex ", which is plantar flexion of the first three toes and sometimes the foot with extension of the knee, induced by stroking of the upper anterior surface of the thigh.

Plantarflexion of the foot : Primary muscles for plantar flexion are situated in the Posterior compartment of leg, namely the superficial Gastrocnemius, Soleus and Plantaris ( only weak participation ), and the deep muscles Flexor hallucis longus, Flexor digitorum longus and Tibialis posterior.

An example of this would be ankle exoskeleton using one pneumatic artificial muscle for dorsiflexion based on tibialis anterior ( shin muscle ) EMG and another pneumatic artificial muscle for plantar flexion based on soleus ( calf muscle ) EMG . This could result in a large degree of co-activation of the two actuators and make walking more difficult.
