Not exact matches
That's right — never, as opposed to movements such as
deadlifts which are commonly used around the home,
during outdoor
activities, and especially if you have a physically demanding job.

activity displays superior muscle
activity during the top half of the
deadlift, while the middle trapezius displays superior muscle
activity during the bottom half.

activity is greater
during the start and middle phases of the
deadlift compared to the top of the lift.
Comparing the phase of lift, Carb et al. (2014) investigated the muscle
activity of the upper trapezius
during conventional
deadlifts performed with a 1RM load, and further compared the muscle
activity at the moment of lift - off and as the bar passed the knees.
During the
deadlift, it appears that trapezius muscle
activity is greater with increasing load while
deadlift type or grip technique has no effect.

activity was higher
during the Romanian
deadlift compared to the prone leg curl but similar in the Romanian
deadlift and both glute - ham raise and good morning exercise.

activity during compound exercises, including the leg press, back squat, overhead squat,
deadlift and split squats.
Assessing exercise technique in the
deadlift, Escamilla et al. (2002) examined the medial and lateral gastrocnemius muscle
activity during the sumo and conventional
deadlift variations.
Therefore, it appears the middle trapezius muscle
activity is maximised at the trunk angle achieved
during the start and mid point of the
deadlift.
Simply doing strong diaphragmatic breathing
during routine sets of squats and
deadlifts helps to get more glute and hip flexor
activity in the movement through fascial links of the diaphragm.
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.
McAllister et al. (2014) compared gluteus medius EMG
activity during the glute - ham raise, good morning, Romanian
deadlift (RDL), and prone leg curl, which are primarily hamstrings exercises.
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, rectus abdominis or external oblique muscle
activity is moderate, indicating that it may be a useful exercise for the abdominals.
Assessing the effect of equipment, Escamilla et al. (2002) explored the muscle
activity of the abdominals
during conventional and sumo
deadlifts with and without a weightlifting belt.
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.
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.
The rectus abdominis and external oblique display moderate levels of muscle
activity during squat and
deadlift variations, but there is no difference in muscle
activity of the abdominals between the squat and
deadlift.
Comparing two different velocities
during an isokinetic machine
deadlift test, Noe et al. (1992) found no differences in quadriceps muscle
activity between the two speeds used (45.7 vs. 30.5 cm / s).
Intervention — any acute study assessing the muscle
activity of the abdominal muscles
during the
deadlift exercise
Comparing the effects of a weightlifting belt, Escamilla et al. (2002) found differences in both rectus abdominis and external obliques muscle
activity between using a belt and when not using a belt,
during both sumo and conventional
deadlift styles.
Comparing the effects of a weightlifting belt, Escamilla et al. (2002) found no differences in muscle
activity when using a belt and when not using a belt,
during both sumo and conventional
deadlift styles.

activity of the quadriceps

Comparing
deadlifts with different grips, Beggs et al. (2011) compared the conventional

activity during sets with 60 and 80 % of 1RM load.
