Example 1 – Cristiano Ronaldo Football strike:
Bones and Joints:
Kicking a football uses all of the bones and joints in your lower body. The tarsals, metatarsals and phalanges of your foot provide the contact surface that strikes the ball. The tibia and tarsals form your ankle joint, which must stay slightly flexed but rigid when you kick so that no power is lost. Your knee joint, consisting of the tibia and femur, extends as your thigh muscles contract and your hip, which is made up of your femur and ilium, swings forward in a movement called hip flexion.
Muscles of the Lower Leg:
The primary muscles in your lower leg used in kicking a football are on opposite sides of your tibia, or shin bone. Your gastrocnemius and soleus muscles, collectively called your calf, contract to …show more content…
This action, called knee extension, is the result of the contraction of the muscles on the front of your thigh. These muscles are called your quadriceps, which are made up of group of four individual muscles -- the vastus lateralis, rectus femoris, vastus medialis and vastus intermedius -- that share a common insertion point at the top of your tibia just below your patella, or …show more content…
Hip flexion is the largest joint action when kicking a football, because it starts from a position of extension and finishes with a significant follow-through. The main muscles responsible for hip flexion are psosas major, psosas minor and iliacus, which are collectively known as Iliopsoas, or hip flexors. These three muscles work with your quadriceps muscle rectus femoris and are responsible for the majority of the power required for kicking a football. To allow hip flexion to occur, your three hamstring muscles -- semitendinosus, semimembranosus and biceps femoris -- must relax. Tight hamstrings may hamper your kicking
