VMO stands for vastus medialis oblique and is part of the vastus medialis quadriceps muscle at the front of the thigh. Here we explain why strengthening this muscle is so important for knee rehabilitation.
What is VMO exercise?
VMO. Cristiano Ronaldo. Sports Knee Therapy. Most often this knee muscle is referred to as the VMO. You may also hear it being referred to as the “tear drop” muscle as it is shaped exactly like a tear drop.
Where is the vastus lateralis located in the body?
Vastus lateralis. The vastus lateralis muscle is located on the side of the thigh. This muscle is the largest of the quadriceps group (often called quads) which also includes the rectus femoris, the vastus intermedius, and the vastus medialis.
|Vastus intermedius muscle|
|Actions||Extension of knee joint|
|Insertion||Pes anserinus (tibia)|
|Artery||Inferior gluteal artery, perforating arteries|
|Nerve||Sciatic (tibial, L5, S1, S2)|
|Actions||Flexion of knee, extension of the hip joint|
The sartorius muscle is a long, slim, superficially running extensor of the thigh musculature. It originates from the anterior superior iliac spine of the pelvic bone and runs spirally towards the knee region. There it inserts at the pes anserinus medially from the tibial tuberosity.
It is called so because it causes abduction and lateral rotation at hip joint which would be a critical action for all the action that is required during the Honeymoon :P :) Gracilis is quite opposite to it as it causes adduction and hence is called anti-rape muscle or custodian of virginity!
In summary, skeletal muscles are attached to bones on each end by tendons. The origin is the fixed attachment, while the insertion moves with contraction. The action, or particular movement of a muscle, can be described relative to the joint or the body part moved.
Short muscle bellies. A short muscle belly means that the muscle attaches high on the tendon, meaning the tendons are somewhat long and the muscle is somewhat short. On the other hand shorter biceps (or other muscles for that matter) peak and protrude more easily.
The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.
In the muscular system, muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood.
There are three types of muscle found in the human body:
- Skeletal Muscle.
- Smooth Muscle.
- Cardiac Muscle (heart muscle)
These muscles push materials like food or blood through organs. Unlike skeletal muscle, smooth muscle can never be under your control. Cardiac muscle is also an involuntary muscle, found only in the heart.
Estimating Muscle Mass. When determining muscle mass, you want to know how much skeletal muscle you have, and this includes those muscles you're working out at the gym. According to Heymsfield, 30 to 40 percent of a healthy person's body mass is made up of skeletal muscle.
According to this research paper, men who are between 20-40 years old with under 8% body fat are considered “underfat”, whereas a “healthy” range is described as between 8-19%. For women in this same age group, any level under 21% is “underfat” and 21-33% is considered “healthy”.
A skeletal muscle fiber is surrounded by a plasma membrane called the sarcolemma, which contains sarcoplasm, the cytoplasm of muscle cells. A muscle fiber is composed of many fibrils, which give the cell its striated appearance.
After you workout, your body repairs or replaces damaged muscle fibers through a cellular process where it fuses muscle fibers together to form new muscle protein strands or myofibrils. These repaired myofibrils increase in thickness and number to create muscle hypertrophy (growth).
The 6 supplements listed below may help you gain more muscle with your exercise program.
- Creatine. Creatine is a molecule that's produced naturally in your body.
- Protein Supplements. Getting enough protein is critical for gaining muscle.
- Weight Gainers.
- Branched-Chain Amino Acids.
The muscle repairs these tears when you're resting, and this helps muscles grow in size and strength.” So when you lift weights, you're actually slightly damaging your muscles by allowing them to lift more weight than they would in normal daily life. “Muscles become sore after training because of the microscopic tear.
Muscle strain, muscle pull, or even a muscle tear refers to damage to a muscle or its attaching tendons. The tearing of the muscle can also damage small blood vessels, causing local bleeding, or bruising, and pain caused by irritation of the nerve endings in the area.
A pulled or torn muscle is an injury where the muscle actually rips. A muscle tear is unpredictable and it happens when the muscle is stretched too quickly. Most often it occurs while the muscle is in motion, such as when running, working, or participating in other forms of physical activity.
