Intervention — any acute study assessing the muscle activity of the erector
spinae during the deadlift exercise
Not exact matches
Noe et al. (1992) assessed erector
spinae muscle activity
during an isokinetic machine
deadlift, and found that erector
spinae muscle activity peaked at 83 % of lift height, which was after the point where peak force output was produced (67 % of lift).
Assessing the effects of equipment, Escamilla et al. (2002) explored erector
spinae muscle activity (at L3)
during conventional and sumo
deadlifts with and without a weightlifting belt.
Comparing a range of compound exercises, McAllister et al. (2014) explored erector
spinae muscle activity
during the leg curl, good morning, glute - ham raise, and Romanian
deadlift with 85 % of 1RM.
Lower erector
spinae muscle activity is very high
during both back squats and
deadlifts.
During deadlifts, training with faster speeds, using conventional or sumo
deadlift technique, introducing an unstable surface, and using a weightlifting belt do not affect erector
spinae muscle activity.
Therefore, the data appears to indicate that the erector
spinae displays superior muscle activity
during the second half of the conventional
deadlift and not necessarily at the same point as the region in which maximum force is exerted.
The «leg biceps» - femoris biceps - and the erector
spinae in the lower back worked less hard
during the trap bar
deadlift.
When controlling for relative load, bar speed does not affect erector
spinae muscle activity
during deadlifts.
