Knee pain or hip discomfort after crouching or squatting is typical in those people with limited decreased back, hip and knee muscle groups. Most of us who sit all day very long have restricted muscles in the lessen back again and reduce limbs. So when we carry out crouching or squatting movements whether or not performed in a prolonged manner or repetitively, you may well experience weakness, discomfort or suffering in the hips, groins, front of the thighs as very well as alongside the interior aspect of the thighs and perhaps even knee pain. This must tell you that the muscle tissues in these parts had been abused by the crouching or squatting positions.
The muscle accountable for distress or soreness at the front of the thighs or pain in the front of the knees is the rectus femoris muscle mass and the muscle at the internal factor of the thigh and knee that has been pressured is the adductor magnus muscle.

If pain is in the outer part of the knees, the agony is very likely to be from stress to the tensor fascia lata muscle and if suffering is at the again of the knees, the suffering is from the hamstrings muscle tissues.
Despite the fact that the other quadriceps muscle tissues are crucial for producing anterior thigh and knee discomfort, they are not the main muscle groups to be injured due to the fact the other quadriceps cross only one particular joint namely the knee joint while rectus femoris (which is also a quadriceps muscle), tensor fascia lata and hamstrings cross both equally the hip and knee joints and are thus more very likely to be abused with crouching or squatting.

In the beginning, anterior thigh and knee agony is extra common than posterior thigh soreness. Due to the fact of our sedentary positions involving sitting for prolonged intervals, the muscle tissue in the entrance of the hip these kinds of as rectus femoris, tensor fascia lata and psoas major could be chronically shortened whilst the muscle groups in the again of the hip, the gluteus maximus (buttock muscle mass), hamstrings and adductor magnus are chronically in excess of- stretched and weakened.

At the knee joint, sitting down places the knees in a bent placement, hence the rectus femoris and the tensor fascia lata whose capabilities are to increase the knee are around stretched and weakened whereas the hamstring muscle tissues whose function is to bend the knee become shorter and restricted thanks to the imbalance of muscle mass electricity as in the see-noticed theory.

Upon crouching or squatting, the sitting posture is exaggerated with abnormal hip and knee bending. Consequently, the rectus femoris and tensor fascia lata muscle groups come to be shorter and tighter at the hip and far more very long and stretched out at the knee. Abnormal shortening contraction in bending (flexion) at the hip and too much lengthening contraction in straightening (extension) at the knee injure both of those rectus femoris and tensor fascia lata muscle groups.

To retain the man or woman in a crouched posture or squatting placement, muscles at the back of the hip have to undergo an too much lengthening contraction in addition to an excessive shortening contraction at the knee. Given that muscles at the back of the hip that have to endure a lengthening contraction this sort of as the gluteus maximus and adductor magnus are enormous and pretty sturdy, the hamstring muscle groups which also does the same motion at the hip can now have additional concentrated ability for bending the knee. The much better the pull of the hamstring muscles to actively bend the knee, the far more ability the rectus femoris and tensor fascia lata muscular tissues have to exert to counteract this pressure.

Therefore, when you consider to stand erect soon after crouching or squatting, the initial weakness, soreness or pain will be felt in the front of the thigh and entrance of the knee providing increase to thigh pain and knee discomfort.
