This is because of differences in external moment arm lengths, which can be either knee flexor or
knee extensor between different individuals and when using different barbell types.
Not exact matches
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 lower during powerlifting squats than during Olympic weightlifting - style squats, even though the powerlifting squats involved the use of greater absolute loads; Swinton et al. (2012) reported that peak
knee extensor moments were greater in the box squat variation than in either the traditional or powerlifting squat variations, but there was no difference
between traditional and powerlifting squats.
Similarly, Wallace et al. (2002) noted that peak
knee extensor moment increased
between squats with no load to squats with a barbell load equal to 35 % of bodyweight.
As explained above, COD maneuvers most commonly involve force production when the hip
extensors and
knee extensors are at moderate muscle lengths (although the exact joint angles can vary widely
between individuals and tasks).
