Not exact matches
It is most commonly seen at the top position of a
deadlift, but it can also be seen
during back
extensions, where lifters often go above the healthy movement range of the joint and expose themselves to the risk of injury.
As relative load increases
during performance of the conventional
deadlift exercise, the ratio of the net hip
extension moment to the net knee
extension moment also increases.
Again, the average hip
extension moment measured
during the
deadlift is often as large or larger than that measured
during dynamometry.
The hip
extension moment becomes progressively more important
during squats,
deadlifts, lunges, running and jumping, as either load or speed are increased.
Studies have reported that several factors affect the magnitude of the hip
extension moment measured
during deadlifts in addition to the type of subjects and the percentage of 1RM used, including style and technique.
Moreover, the hip
extension moment measured
during deadlifts appears to be slightly greater than that measured in the traditional back squat and this may be a result of the greater peak external moment arm at the hip, (c.f. Escamilla et al. 2000; Escamilla et al. 2001b).
