The movements involved in the action of standing up is when the muscles contracting. The muscles that are needed to perform these actions are the glutes, hamstrings, and the quadriceps.

These muscles begin at the ischial tuberosity, which is at the bottom of the pelvis. The muscles meet at the knee joint and end at the lower leg, where they are joined together through connective tissue that attach the tendons to the bones like double-sided tape. The hamstring muscle groups work to help extend the leg back and provide motion at the knee. Due to the crossing

The vastus lateralis muscle is situated in side of the thigh.This Muscle is the biggest of the quadriceps group which also includes the rectus femoris, the vastus intermedius, and the

The biceps femoris is one of the three muscles including the semitendinosus, and the semimembranosus, that make up the group of muscles called the hamstrings. The hamstrings are located on the posterior side of the leg. The biceps femoris originates on the ischial tuberosity and inserts on the head of the fibula. The movement of the biceps femoris is responsible for the flexion of the knee and the external rotation of the lower leg. Flexion of the knee happens when the back of the foot is raised toward the back of the leg.

The popliteus muscle is a minor flexor of the knee. It penetrates the joint capsule to find its origin on the lateral condyle of the femur, and passes obliquely to insert on the medio-proximal tibia. Its main function is to help stabilize the knee, but is also able to rotate the femur on the tibia to unlock the knee.

Loyola University Medical School states that the gluteus medius’ origin is the outer surface of the ilium between posterior and middle gluteal lines, and that its insertion is the posterolateral surface of the greater trochanter of the femur. It also states that its action abducts and medially rotates the hip, and tilts

The next progression of the preparatory phase is abduction of the hip. When performing this motion, the goal is to abduct the thigh to a point that is past the lower leg of the opponent. For this, the agonist muscles are the sartorius, gluteus medius, gluteus minimus, and the tensor fascia latae. Opposing this are the antagonists, which consist of the pectineus, adductor brevis, adductor longus, adductor magnus, and the

Proximally, (VM) attaches to the proximal femur. Starting at the intertrochanteric line and moving posteroinferiorly to the medial supracondylar line (having passed over the pectineal line and the medial lip of the linear aspera (Drake et al 2013)). Distally the VM attaches to the medial boarder of the patella bone over the knee joint.

The knee is a hinge joint which gives the legs mobility. The muscles and ligaments of this joint allows flexion and extension of the leg. “Because the knee supports the majority of the body weight, it is at risk of overuse and traumatic injuries” (France). The knee is composed of 3 major bones; the femur, tibia, and the fibula. The femur is the biggest bone in the human body, the inferior end flares out into two rounded landmarks called femoral condyles. Their name comes from the side of the body they are on, which is where we get Lateral Femoral Condyle and Media Femoral Condyle. Superiorly to these condlyes are the medial and lateral femoral epicondyles. The bones inferior to the femur are the Tibia and Fibula. The superior end of the Tibia flares out into slightly concave structures called the Tibial Plateaus. A crescent wedge shape of cartilage sits in each plateau. These are the Medial Meniscus and the Lateral Meniscus. This cartilage acts as a shock absorber and distributes forces. “The menisci are bathed by the synovial fluid of the knee” (France). The meniscus is what separates the each side of the Tibia and Femur and the transverse ligament connects each menisci. There is a circular bone on the

Beginning from the lower half of the body there are primary muscles that contract to produce dorsiflexion of the calcaneus: the tibialis anterior and pernoneous tertius are the agonists and the peroneous longus and peroneous brevis are the antagonists of this action. Although, when dorsiflexion reverses to plantaflexion the roles of agonist and antagonist also reverse. Therefore the peroneous longus and peroneous brevis are now the agonists and the tibialis anterior and pernoneous tertius are the antagonists of this reversed action.

As can be seen from the image plate from Gray's Anatomy the gluteus maximus lies over the medial portion of the

The greater trochanter extends superiorly from the shaft of the femur, lateral to the part where the shaft joins the neck of the femur. Continuing posteriorly, its medial surface

Next, Matt has to push up using all of his strength. Muscle used in this process are the Hamstrings which flex the knee for movement, the soleus, which provides power to the ankle, and the Tibilias anterior, which inverts the ankle. Now, Matt is finally in standing position. In this position, Matt is using his Gluteus Maximus, one of the strongest muscles in the human body, and this allows for movement of the hip & thigh. Also, Matt is using his Hamstrings, Soleus, and Tibilas anterior, which very also used in other positions in the process of standing from sitting position. With all of the different muscles used in this process of standing from sitting position, there were also various nerves that inverted these muscles. For the Quadriceps it would be the femoral nerve, the Fibularis Longus with the Peroneus longus nerve, the Latissimus Dorsi with the Thoracodorsal nerve, the Gluteus medius which uses the superior gluteal nerve, and the gluteus maximus which uses the inferior gluteal nerve, the Internal oblique which uses the both the iliohypogastric nerve and the ilioinguinal nerve. Also, the Trapezius which uses

This classic exercise is widely used because of its effectiveness. Push-ups strengthen the shoulders, triceps, biceps and upper back muscles. Lay on the ground with your legs straight behind you and your arms next to your chest. Keeping your back straight, push your arms up until they are straight and bend again until your chest almost touches the ground. Straighten your arms again and repeat. Push-ups can be done from the knees for an easier, but still effective,
