The leg muscles represent a very strong group of muscles. They have to carry the body weight all day long and stabilize important joints, such as the knee and ankle.
The leg muscles – front and back side of the upper leg
The muscles of the upper leg (thigh) are determined by a rather complex structure. On its front the quadriceps femoris can be found (front thigh muscles). Consisting of the rectus femoris, vastus medialis, vastus lateralis, and vastus intermedius it protects and stbilizes the knee joint. All four parts of the quadriceps femoris extend the knee joint. The rectus femoris also flexes the hip joint and tilts the pelvis.
On the back side of the thigh there are the biceps femoris, the semitendinosus, and the semimembranosus. Together these muscles represent the ischiocrurales (hamstring) and flex the knee joint. They also extend the hip joint and support the pelvis erection.
Most people show an imbalance between the leg muscles of the front and back side of the thigh what can cause knee problems. In most cases exercises for the thigh back side are neglected and should be part of the workout more often.
The leg muscles – adductors and abductors
The adductors are located on the inner side of the thigh and are a group of five different muscles that pull the leg towards the body (adduction). The abductors represent a group of several muscles, which are the three parts of the butt musculature, the rectus femoris, the tensor fasciae latae, the sartorius, and the piriformis. Among other functions they are all together responsible for the abduction of the leg from the body. Together with the adductors the abductors help to stabilize and balance out the pelvis.
The leg muscles – lower leg
The calves are the muscles of the lower leg which are referred to as the gastrocnemius and the soleus, or together as the musculus triceps surae. The triceps surae extends the ankle joint and rotates the foot inwards. It also balances out the body weight on the foot.
