What is the purpose of hamstrings?

Answer 1

he hamstring muscles are located on the back of your thigh. They work closely with your quadriceps muscles (front of your thigh), your gluteal muscles, and your calf muscles to ensure proper movement of your leg and hip.

Your hamstring muscles control movement of your body, hip and knee, help turn your leg in and out, and are involved with power activities that include a lot of propulsion, thrust and control (such as jumping, running, and walking). They allow your knee to bend (flex the leg at the knee) and pull your leg backward while propelling your body forward when you move (your thigh straightens and extends the leg back at the hip). They are involved with eccentric movements, which increase the length of the muscle while it is under tension ­ instead of starting an action, the muscles act as a brake to stop an action. You can feel this when walking or running downhill, landing from jumps or performing squats, and when trying to stop quickly after sprinting. The hamstrings (posterior thigh muscles) are made up of 3 long muscles that start at the bottom of your pelvis extending down the back of your thigh and along either side of your knee, to your shin bones. The lateral hamstring is the biceps femoris (made up of 2 parts - a short head and long head) and the medial hamstrings are the semitendinosus (joins the sartorius muscle and gracilis muscle at the pes anserinus on the tibia) and the semimembranosus (the largest hamstring muscle). The tendons (tough fibers that connect muscle to bone) for these muscles begin at your ischial tuberosity (the bony bump under each buttock, known as your "sit bone") and attach on the outer edges of your shinbone (your tibia and fibula) just below the back of your knee. They help to stabilize your knee. Your hamstrings also have a lot of soft connective tissues and are innervated by your sciatic nerve. From: http://www.aidyourhamstring.com/pulled-hamstring.php

Answer 2

The "commonly thought of" primary functions of the Hamstrings are knee flexion (bringing the heel towards the buttocks) and hip extension (moving the leg to the rear).

An example of knee flexion is the leg curls exercise and an example of hip extension is the stiff-legged deadlift exercise.

In movement, the hamstrings "primary" function is NOT knee flexion. In walking or running, for example, the primary function of the hamstring is to decelerate the lower leg in the saggital plane. Positionally, knee flexion in walking/running occurs as a result of hip flexion and plantarflexion, again positionally. When the body responds to gravity, function changes.

Answer 3

Basically, the function of the hamstring-muscle group is to flex the knee and extend the hip joint.

Answer 4

•The hamstring allows you to bend your leg at the knee.

Answer 5

ham strings is small strings made of ham. you can also find chicken strings and beef strings. they help you eat

Answer 6

The hamstrings have two functions. They flex the knee and extend the hip.

Answer 7

The hamstrings work in opposition to the quadriceps and primarily flex the knee and extend the hip.

Answer 8

hip extension, knee flexion, leg rotation
