For example, tests are used for identifying the presence
of knee valgus during drop landings (Nyman & Armstrong, 2015), knee valgus during the barbell back squat (Kushner et al. 2015; Snarr & McGinn, 2015), or lumbar rounding during the barbell back squat (Kushner et al. 2015; Snarr & McGinn, 2015).
There are some reports that increased adductor muscle activity may be related to the display
of knee valgus during certain movements, including bilateral squats (Padua et al. 2012) and unilateral squats (Mauntel et al. 2013).
Moreover, Lloyd and Buchanan (2001) noted that the gracilis does possess a muscle moment arm that is supportive
of knee valgus moments during knee extension movements.
Generally speaking, lifters who squat narrow keep their feet pointed forward and lifters who squat with a wider stance tend to flare their feet slightly, thereby allowing for a greater hip involvement and reducing the risk
of knee valgus.
Not exact matches
Female athletes have wider hips, putting a higher
valgus stress angle on their
knees (
knees inward), a stress that is the major factor
of most non-contact ACL injuries.
Soft surfaces — such as sand and grass, requires more stability and challenges pronation, inward collapsing
of the
knees (
valgus) and base
of support.
MYTH Anatomical abnormalities
of the lower body such as flat feet or
knee valgus make people more susceptible to running injuries.
The most common compensations seen in those with a hip internal rotation deficit (HIRD) include overpronation at the feet, a
knee valgus, reduced step length, external rotation
of the foot toward terminal stance phase and increased lumbar and
knee extension.
Of course, I couldn't leave out another common HUGE mistake — >
Knees Caving /
Valgus Collapse!
The caveat is only if you perform them properly - not with the eye watering
knee valgus and lack
of hip extension that the typical player performs the lifts with that more resembles a sumo squat - reverse curl combo.
DO NT DO: ❌
Knees Caving /
Valgus Collapse — super common when squatting with an anterior pelvic tilt & heels lifted, especially when coming out
of the hole.
Anatomical abnormalities
of the lower body such as flat feet or
knee valgus make people more susceptible to running injuries.
Excessive
knee valgus has been linked to gluteus medius weakness, by way
of reduced hip abduction strength (Jacobs et al. 2007; see review by Cashman, 2012).
Knee valgus is thought to be an important predictor
of anterior cruciate ligament injury, particularly in females (Hewett et al. 2005).
Of particular note is the trial by Lubahn et al. (2011), which reported that adding a lateromedial (outward) force during the single - leg squat directed to increase knee valgus actually decreases the muscle activity of the gluteus mediu
Of particular note is the trial by Lubahn et al. (2011), which reported that adding a lateromedial (outward) force during the single - leg squat directed to increase
knee valgus actually decreases the muscle activity
of the gluteus mediu
of the gluteus medius.
The gluteus medius is commonly a target
of rehabilitation, hypertrophy and strengthening for a number
of different musculoskeletal conditions, including lateral hip pain, hip osteoarthritis, hip replacement,
knee valgus, patellofemoral pain, low back pain, and iliotibial band syndrome.
Tighten Your Buns: Glute Bridges or Hip Thrusts One
of the most common issues people have with squatting is known as
valgus collapse, or the
knees collapsing inwards during the «up» phase
of the exercise.
They observed that lower levels
of gluteus maximus EMG amplitude that predicted reduced
knee valgus.
However, the contribution
of gluteus maximus force production and neuromuscular activity to
knee valgus during normal movement remains unclear.
