Transcript of Rugby Conversion

Rugby Kick There are three main joints used when kicking a rugby ball. In this presentation you will detail common movements in three different types of joints whilst participating in an activity of your choice. As part of this presentation you will need to consider the role of muscles in the clear and concise movement that you chose to describe. In addition you will need to describe the muscles origins and insertions using appropriate diagrams and images to support your work. Ball & Socket joint at the Hip
Hinge joint at the Knee
And also at the Ankle, although the knee and Ankle joints are not 'true' hinge joints. The one thing that all three
joints do have in common
is that they are all Synovial joints.
which means freely moveable. The kick that we will be describing is for
a forward facing punt, much like the one in
the picture. The order in which the kick begins its movement is.
Flexion of the knee
Extention of the hip
Plantarflexion of the ankle This is the back swing phase The second part of movement is the forward swing phase this is when the performer brings their leg forward to strike the ball.
The mechanics of the forward phase are:
Flexion of the hip
Extention of the knee
The foot stays in the plantarflexion position throughout the movement. The muscles that act in the backward movments are as follows: Knee Flexion The muscles used in this movment are the hamstrings these consist of: Hip Extention Plantarflexion This is the last movement in the backward phase of the kick Hip Flexion This is the forward momentem from the hip and the muscles involved in this movement are: Knee Extention The foot stays in plantarflexion and strikes the ball. This movement is done simultaneously to the hip flexion to create a strikeing action, the muscles are: The bones of the hip involved are the femur and pelvis which forms a ball and socket joint.
The bones of the knee involved are the femur and tibia which form a hinge joint.

The bones of the ankle involved are the tibia and calcaneus which form a modified hinge joint. Hip
• Gluteus maximus - Extends and rotates thigh laterally.
• Rectus femoris - Extends knee and flexes hip
• Vastus lateralis - Extends knee
• Vastus medialis - Extends knee
• Vastus intermedius - Extends knee
• Vastus lateralis - Extends knee
• Vastus medialis - Extends knee
• Vastus intermedius - Extends knee
• Sartorius - Flexes knee. Flexes hip and rotates femur laterally
• Biceps femoris - Flexes leg and extends thigh
• Semitendinosus - Flexes leg and extends thigh
• Semimembranosus - Flexes leg and extends thigh
• Gastrocnemius - Plantar flexes foot and flexes knee
• Soleus - Plantar flexes foot
• Plantaris - Plantar flexes foot
• Tibialis posterior - Plantar flexes and inverts the foot
• Peroneus longus - Plantar flexes and everts the foot
• Peroneus brevis - Plantar flexes and everts the foot
Times Up To conclude this in the simplest form, Joints involved Action Agonist Muscle Joints Involved

Hip Extension and hyperextension Gluteal muscles (gluteus Hip
maximus and gluteus minimus)

Knee Flexion Hamstrings (biceps femoris, semi- Knee
membranosus, semitendinosus)

Hip Flexion Iliopsoas Hip

Knee Extension Quadriceps group of muscles (rectus Knee
