Hip & Pelvic Muscles
The Tensor Fasciae Latae (TFL) is a small muscle which attaches inferiorly to the long thick strip of fascia, known as the iliotibial band (ITB).
When running the hamstrings act eccentrically to slow down the knee extension motion. Hamstring strains are common in individuals with chronically tight hamstrings or who do not warm-up thoroughly.
Semimembranosus is the most medial of the three hamstring muscles. Chronically tight hamstrings are often a contributary factor to lower back pain and knee pain.
The Sartorius is a two joint muscle and so is weak when the knee is flexed and the hip is flexed at the same time. It works better during single movements.
The Rectus Femoris muscle is part of the Quadriceps muscle group. It is the only muscle of the group which crosses the hip joint and is a powerful knee extensor when the hip is extended, but is weak when the hip is flexed.
The Piriformis muscle is an important muscle. The sciatic nerve passes underneath this muscle on its route down to the posterior thigh. In some individuals the nerve can actually pass right through the muscle. This can lead to sciatica symptoms due to a condition known as piriformis syndrome.
Pectineus is positioned between the Iliopsoas and Adductor Longus muscles and is part of the short adductor group with adductors brevis and longus.
Iliopsoas is sometimes classified as two muscles, Iliacus and Psoas major, with Iliacus arising from the Ilium and Psoas from the vertebrae.
Gracilis is another muscle which works in conjunction with the groin muscles, or adductors.
This is the smallest of the three gluteal muscles and sits underneath the gluteus medius.
Gluteus Medius is an important muscle in controlling the level of the hips. Weaknesses in gluteus medius often result in a trendelenburg sign, an abnormal gait cycle where the hip of the swinging leg drops down, rather than raises up. This results in increased degrees of knee flexion in order to clear the ground.
Gluteus Maximus is the largest and most superficial of the three gluteal muscles which forms the rounded shape of the buttocks.
Biceps Femoris is one of the three muscles which form the hamstring group forming the back of the thigh. The muscle is often described as having a long head (the attachment from the ischium) and a short head (attached to the femur).
Adductor Magnus is the largest groin muscle and is one of the two long adductor muscles (gracilis is the other). It is usually described as having two parts, hamstring and adductor parts.
Adductor Longus is the middle of the three short adductor muscles. Groin strains are common injuries to the adductor muscles, which occur without a thorough warm-up or in individuals with chronically tight or weak adductor muscles.
Adductor Brevis is the smallest and shortest (hence the name brevis, meaning short in latin) of the three short adductor muscles. Groin strains are common injuries to the adductor muscles, which occur without a thorough warm-up or in individuals with chronically tight or weak adductor muscles.
