The glutes are the largest muscle group in the body and are comprised of the glute maximus, medius and minimus. These muscle groups play a vital role in maintaining the posture of the trunk, supporting, and propelling the weight of the body while assuring proper pelvic alignment and hip stabilization.
One of the adverse effects of inactivity or a sedentary lifestyle is a weakness of the glute muscles that can affect the biomechanics of the body and causing poor posture, low back pain and knee pain.
One condition that can be caused by weak glute muscles is low back pain.
The weakness of the glute muscles could impair their ability to stabilize the pelvis and properly support the weight of the body. To compensate for this weakness, the low back muscles need to be recruited causing increased strain and tension on them, overloading the spine and the intervertebral discs and leading to low back pain.
Weak glutes/knee pain The weakness of the glute muscles is associated with hip instability that will affect a proper walking and running gait. A weak glute medius muscle would allow the thigh to rotate and move inwards. This abnormal position of the thigh can cause excessive stress on the knee joint and the kneecap which combined with the repetitive motion of walking and running would result in knee pain.
