Quadriceps femoris muscle

my attention in that it talked of how an electrical stimulation added to exercise will help improve or gain full voluntary active movement of the quadriceps muscles in patients with total knee arthroplasty (This…

When you do these exercises, do you push through your toes or through your heels? If you said heels, you are correct. We as a society are very quadricep dominant. When we have too strong or over active quadriceps compared to our hamstrings, this is when knee injuries can occur. A big tip to remember is when you push through your toes that works your quadriceps and when you push through your heels that works your glutes and hamstrings. When we do most exercises that involve us pushing up…

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…

Electrical stimulation: Eight self-adhesive 7x13 cm oval carbon electrodes were adhered to the skin over the quadriceps and hamstring muscles (four electrodes per leg). These muscles were selected because of their ease of access, clinical importance, and large size, which we reasoned would yield the greatest potential for altering energy expenditure. The distal margin of the distal quadriceps electrode was placed over the distal-most palpable border of the vastus lateralis. The proximal…

(Berglund et al, 2015). The Biering-Sorensen test evaluates the hip and back extensor muscles aerobic capacity. This rehabilitative exercise also helps to improve a reduction in the pain intensity the patient experiences. Furthermore, improvement is seen in the lumbopelvic movement control, which allows for a larger range of motion (Berglund et al, 2015). The deadlift requires muscles from all across the body to complete the action in its…

are also very important. One important muscle group of the leg includes the quadriceps muscles, otherwise known as the quadriceps femoris. The quadriceps are made out of four other different muscles, that all work towards a specific function for the body. Although it might not be one of the most important muscles, the quadriceps muscles are a very important leg muscle that has a great impact on our lives. The quadricep femoris muscles cover most of the femur and is made up of four parts. These…

Echo intensity is commonly used to assess muscle quality as an outcome measure in muscle physiology research. Muscle quality is an indicator of overall functional capacity and is negatively correlated with echo intensity (Watanabe et al., 2013). Echo intensity is defined as the mean pixel intensity in the muscle and is determined by gray scale analysis using B-mode ultrasonography (US; Watanabe et al., 2013). Lean muscle has low echogenicity while muscle with higher amounts of fibrous and…

Healthy joint The knee joint is a synovial joint and connects the femur to the tibia and consists of two joints the tibiofemoral joint, which joins the tibia to the femur and the patellofemoral joining the kneecap to the femur. These two joints work together to form a hinge joint allowing the knee to bend and straighten and to also rotate slightly from side to side. Muscles There are two main muscles groups of the knee, the hamstrings, quadriceps and muscles of the calf all work to flex,…

leads to the spindles providing feedback to the brain. This process is done by the gamma motor neurons, who are in charge of controlling the stimulation of the cerebellum. Also, both the alpha and gamma motor neurons meet at the same effector muscles. Furthermore, when the extrafusal fibers of the muscle spindle contract, the intrafusal fibers change length in correlation to the muscle tone to activate the feedback to the brain, which is done by the gamma neurons. The feedback process is…

ankles, have little flexibility, too much sport or without the proper techniques or an imbalance of the quadriceps and hamstrings can be a cause of occurring excessive pressure to pull the patella causing pain . Among teens who play sports, knee pathologies found are: Osgood-Schlatter's Disease and Larsen-Johannson. The main source in both is too much stress on the bones that are still under development. Let's look more closely. Disease or syndrome of Osgood-Schlatter This syndrome, associated…
