Therefore, it appears that erector spinae muscle activity is higher
during deeper squats compared to shallower squats.

Also, in order to reap the benefits of wearing a weightlifting belt, you have to breathe properly
during heavy lifts — for example, when
squatting, take a
deep breath just before you descend and hold it until you reach the lowest point of the
squat, then perform what is known as the Valsava maneuver (the technique you would use when trying to clear your ears with the help of exhaling) or forcefully exhaling against a closed airway.
That being said, because of the bar placement (anterior on the shoulders) and because one is able to maintain a more upright torso
during its execution, most people will be able to achieve a much
deeper depth with a front
squat.
Bryanton et al. (2012) found that peak hip extensor moments increased with increasing depth (albeit with the same absolute loads) but Wretenberg et al. (1996) reported that peak hip extensor moments
during both powerlifting
squats and
during Olympic weightlifting - style
squats did not differ substantially between
deep and parallel versions (
deep = maximal knee flexion vs. parallel = posterior of the hamstrings parallel to the ground).
Wretenberg et al. (1996) found that peak knee extensor moments were greater
during both powerlifting
squats and
during Olympic weightlifting - style
squats when performed with greater depth (
deep = maximal knee flexion vs. parallel = posterior of the hamstrings parallel to the ground).
If appropriate (based on your knee pathology history) you must eventually assume a
deep squat position
during your training as this position will provide optimum thigh muscle strength and architecture (i.e. cross section area), possible collagen synthesis and hypertrophy of the patella tendon (stronger patella tendon) and enhanced athleticism i.e. improvement in various types of jumps.
Comparing the
squat and deadlift, Hamlyn et al. (2007) examined the external oblique muscle activity and the lower region of the
deep abdominal (superior to inguinal ligament, medial to anterior superior iliac crest) muscle activity
during the barbell back
squat and conventional deadlift with 80 % of 1RM.
