ACTION OF THE HAMSTRING MUSCLES DURING THE SQUAT

Hamstrings Pelvis

Straightening the pelvis erects the torso.

IT] The hamstrings contract to straighten the pelvis.

Straightening the pelvis erects the torso.

IT] The hamstrings contract to straighten the pelvis.

While performing the squat, the hamstring muscles contract to straighten the pelvis, which at the same time prevents the torso from tilting too far forward (as long as pelvis is aligned with the torso by contracting the abdominal and lumbar muscles).

Muscle tearing of the hamstrings

In bodybuilding, hamstring tears occur frequently. This injury occurs most often during the squat when the torso is too far forward. The hamstring muscle group, with the exception of the short head of biceps femoris, is In an extremely stretched position and contracts forcefully to straighten the pelvis. This can lead to tearing, most often at the high or middle portion of the muscle group. Hamstring tears can also occur when working at a leg curl machine using heavy weights. This most often occurs at the beginning of the movement when the legs are extended and the muscles are stretched.

Although in general, the tears in hamstring muscle fibers are not extensive and not serious (it is rare to see a significant tear In the muscle or its tendinous insertion), they are always painful and prone to complications.

In fact, fibrous scarring frequently occurs after a tear In this muscle group, which creates friction that is especially painful and incapacitating during sport activity. Furthermore, this inelastic scar tissue is liable to tear during Intense effort.

Preventing hamstring tearing

To prevent muscle tears, perform either a specific stretching workout or incorporate hamstring stretches during a lifting workout between sets of squats and deadllfts and exercises for the back of the thigh.

Certain weightllfting exercises, such as good mornings or stiff-legged deadllfts, can be considered the best hamstring protectors because of their combined action of muscle strengthening and stretching.

After hamstring tearing

To prevent the formation of fibrous scar tissue in the hamstrings, it is essential to reeducate the muscles as soon as possible. A week after a tear, you must perform gentle stretches for the back of the thighs. The goal is to stretch the injured muscles and especially to soften the scar so that It doesn't tear when you resume training.

RETRACTION OF THE HAMSTRINGS

In today's modem world, sitting for long periods during the day can lead to retraction of the hamstring muscles In certain people. This retraction of the muscles on the back of the thigh tips the pelvis back and reduces the normal curvature of the spine.

Hamstring muscles

Retraction of the hamstrings causes the pelvis to tip back (posterior rotation), which reduces the lumbar curve and sets the stage for vertebral Injuries.

This causes the person to adopt poor posture with the pelvis tucked under and the back rounded, which over time can lead to vertebral injuries. To limit this relatively frequently occurring retraction of the hamstrings, stretching movements such as an easy good morning with straight legs and the stiff-legged deadlift are recommended. Hamstring stretches after a hamstring workout are also recommended.

Comment: A massage therapist can also treat fibrous scars by using massage or mechanical techniques aimed at softening the lesion.

Acne is a name that is famous in its own right, but for all of the wrong reasons. Most teenagers know, and dread, the very word, as it so prevalently wrecks havoc on their faces throughout their adolescent years.
