Contusions
A contusion, which many people simply call a bruise, often develops from an impact to the thigh, which compresses the muscles against the hard surface of this part of the leg. As a result, this trauma may cause bruising and inflammation. It is a common injury in many impact sports and can lead to pain and a reduced range of movement.
Strains
Also known as a pulled quad, this is another common and painful sports injury, particularly among athletes who perform sudden, forceful leg movements. It occurs when a person overstretches a muscle or tendon, especially as a result of fatigue, overuse, or improper use.
Tendinopathy
Tendinopathy refers to tendon injuries that often result in pain, swelling, and impaired function that typically occur from overuse. Tendons are thick tissues that attach bone to muscle. In the case of the quads, they attach these muscles to the patella. Two of the main types of tendinopathy are tendinitis and tendinosis.
Tears
A quadricep tear describes when a tendon becomes either partially or completely severed. It is a similar injury to a strain but involves overstretching and tearing. In some cases, the injury may begin as a partial tear where the tendon is fraying, but then progresses, causing the tendon to tear completely.
Leg press
A seated leg press is another piece of gym equipment. For this exercise:
Leg extension
A seated leg extension is a weight machine that people may find at a gym. After selecting an appropriate weight, a person sits on the machine and puts their feet behind the bar. Then can then extend the quad muscles to straighten the leg and hold this position before slowly returning to the starting position.

What is the function of the quadriceps?
The primary function of the quadriceps is to extend (straighten) the knee. Each muscle has a different origin, but they all attach near the patella (the kneecap).
What muscle is responsible for flexion of the hip joint?
On many people, the rectus femoris is the most noticeable muscle in the quadriceps group as it runs down the middle of the front of the thigh. The rectus femoris is responsible for stabilizing and creating flexion at the hip joint. 1 This occurs when you tip the torso forward or when you bring your thighs closer to your torso.
Why do my quads hurt?
Tight quadriceps can cause an imbalance with the hamstrings and gluteal muscles. When this happens, it is not uncommon to experience hip or lower back pain. Runners and cyclists may experience tight quads. Warming up at an easy pace can help relieve the tightness.
What muscles do you use when you have tight quads?
If one muscle group is tight, it can have an effect on the opposing muscles. For example, those with tight quads may have underdeveloped hamstring and gluteal muscles. One way to relieve the tight quads is to develop stronger hamstrings and glutes to achieve balance.

What is the name of the quadriceps femoris muscle?
It bears this name because it consists of four individual muscles; rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius. Out of all four muscles, only the rectus femoris crosses both the hip and knee joints.
Which muscle contributes to the superficial central part of the quadriceps tendon?
The tendon of the rectus femoris muscle contributes to the superficial central part of the quadriceps tendon. The tendon of vastus medialis makes up the superficial medial part of the quadriceps tendon. The tendon of vastus lateralis comprises the superficial lateral part of the quadriceps tendon.
What is the lateral side of the vastus lateralis muscle?
The lateral side of the muscle is covered by the tensor fasciae latae and gluteus maximus. Its medial surface is related to vastus intermedius, from which it is separated by the lateral femoral circumflex artery and branches of the femoral nerve.
What muscle is deep to the thigh?
The proximal part of rectus femoris muscle lies deep to tensor fasciae latae, sartorius and iliacus muscles. All the contents of the anterior compartment of the thigh lie deep to rectus femoris. These include the capsule of the hip joint, vastus intermedius, anterior margins of vastus lateralis and vastus intermedius, lateral circumflex femoral artery and some branches of the femoral nerve.
What muscle is used to extend the leg at the knee joint?

Structure
Function
- The quadriceps all work to extend (straighten) the knee. The rectus femoris also flexes the hip, The vastus medialis adducts the thigh and also extends and externally rotates the thigh and stabilizes the kneecap.
Usage
- You use the quads whenever you straighten a bent knee. In everyday life, they help you get up from a chair, walk, climb stairs and squat. They are used in walking and running at the onset of a stride and get used significantly when going downhill. They get a real workout with cycling, and cyclists have well-developed quads. The quads are used in jumping and sports like basketball th…
Clinical significance
- The quadriceps are antagonists to the hamstring and gluteal muscles, which do more of the heavy work in running and walking. Tight quads can have an effect on those antagonistic muscles.
Benefits
- Tight quadriceps can cause an imbalance with the hamstrings and gluteal muscles. Runners and cyclists may experience tight quads. Warming up at an easy pace can help relieve tight quads, but using stretches is common.
Causes
- Runners often develop an imbalance between strong hamstring muscles and less developed quadriceps. A pulled or strained quad muscle may result, often during a sudden acceleration, sprint, or kicking action.
