Tibialis Anterior
The ankle does not contain any muscles. To increase the force with which you can flex or extend your foot at the ankle joint, you will need to work on your calf and shin muscles.
The ones below the back of your knee down to your ankle. That would be your calf
your calf and shin muscle. ;)
Calf muscles and the ankle joint serve different but complementary functions in the body. The calf muscles, primarily the gastrocnemius and soleus, are crucial for movements like walking, running, and jumping, providing propulsion and stability. The ankle, on the other hand, is a joint that allows for a range of motion and flexibility necessary for these activities. Therefore, one is not "superior" to the other; they work together to facilitate movement.
Pointing your toes primarily involves the muscles in the back of the lower leg, such as the calf muscles (gastrocnemius and soleus) and the muscles along the top of the foot (dorsiflexors). These muscles work together to extend and flex the ankle, allowing you to point your toes.
Using the calf muscles in the pedal stroke; making the ankle move.
The ankle joint is a hinged joint, classified as a third-class lever in the body. The effort (force) is applied by the calf muscles to move the foot (load) to produce movement at the ankle joint.
The primary joint movement in a seated calf raise is plantar flexion, where the ankle joint is extended and the toes are pointed downward, contracting the calf muscles.
A second-class lever in the body is demonstrated by the action of the calf muscles (gastrocnemius and soleus) when performing a calf raise. The foot is the load, the ankle joint is the fulcrum, and the effort is provided by the contraction of the calf muscles to lift the body weight.
Some effective exercises to strengthen the muscles in your lower leg include calf raises, ankle dorsiflexion exercises, and toe raises. These exercises target the calf muscles, shin muscles, and foot muscles, helping to improve strength and stability in the lower leg.
Your heels may come up when you squat due to a lack of ankle mobility or tightness in your calf muscles. This can cause your body to compensate by lifting your heels off the ground to achieve a deeper squat. Strengthening your ankle and calf muscles, as well as improving your squat form, can help address this issue.
The calf is distal to the knee. There are multiple muscles in the lower leg. Their position relative to the skin is what determines it's depth/superficiality.
