• Rectus femoris: A quadriceps (thigh) ... This exercise is effective because repositioning the hip joint stretches the hip flexors from three different angles, ensuring all the muscles involved ...
The exercise engages all four heads of the quadriceps, the vastus lateralis, vastus intermedius, vastus medialis and rectus femoris. The vastus lateralis has been shown to engage more during the movement when toes are pointed inward. The rectus femoris engages more when the toes are pointed outward. [8]
The posterior division of the L4 root is the femoral nerve. The femoral nerve innervates the quadriceps femoris, a fourth of which is the rectus femoris. When the rectus femoris receives the signal that has traveled all the way from the medial side of the precentral gyrus, it contracts, extending the knee and flexing the thigh at the hip. [2]
The leg raise is a strength training exercise which targets the iliopsoas (the anterior hip flexors).Because the abdominal muscles are used isometrically to stabilize the body during the motion, leg raises are also often used to strengthen the rectus abdominis muscle and the internal and external oblique muscles.
Rectus femoris. Vastus lateralis. ... "Jumping jacks are a form of cardio exercise and not resistance training because they don’t involve a form of external resistance like dumbbells, bands ...
Muscles Worked: A plank is a full-body exercise, but specifically, it works your transverse abdominis, rectus abdominis (aka the six-pack), internal and external obliques and scapular (shoulder ...
The quadriceps femoris muscle is subdivided into four separate muscles (the 'heads'), [1] [2] with the first superficial to the other three over the femur (from the trochanters to the condyles): The rectus femoris muscle occupies the middle of the thigh, covering most of the other three quadriceps muscles. [1] It originates on the ilium. It is ...
The rectus femoris, a large muscle in the quadriceps, is typical. If the central tendon branches within a pennate muscle, the muscle is called multipennate (Fig. 1C), as seen in the deltoid muscle in the shoulder.
