Not exact matches
Since
deadlifts are very taxing and stress the same
muscles used
during other heavy back movements, you will train the
deadlift only once per week and you'll do it few days after your heavy squats.
Given the fact that you are already doing
deadlifts, squats and other similar posterior chain movements
during the training week, you will want your lower back
muscles to be well rested and as fresh as possible.
Upper trapezius
muscle activity displays superior
muscle activity
during the top half of the
deadlift, while the middle trapezius displays superior
muscle activity
during the bottom half.
Overall, it appears that the middle trapezius
muscle 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.
They reported that the gastrocnemius
muscle 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.
Several studies have assessed calf
muscle 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.
This is no reason to not perform them, however, and the mistakes that make these lifts potentially dangerous are more often than not the result of imbalances (quad / hamstring imbalances leading to knees bowing in or forward
during the squat), disproportionately weak
muscles (lower back rounding
during the
deadlift), or balance issues that absolutely need to be addressed for the athlete.
The exercise will require constant activation of many of the same
muscles you'll use
during your
Deadlift.
Also, the conventional
deadlift begins with a positive phase that does not allow you to accumulate elastic energy in your
muscles during the descent (as occurs
during a squat).
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, 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.
As with the squat,
deadlift, and reverse bent over row, the core is activated
during the military press; and barbells or dumbbells can be used, with a barbell preferable, as unilateral movements can sometimes lead to
muscle and strength imbalances.
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).
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.
Intervention — any acute study assessing the
muscle activity of the quadriceps

deadlift exercise
Comparing the effects of a weightlifting belt, Escamilla et al. (2002) found no differences in hamstrings
muscle activity when using a belt and when not using a belt,
during both sumo and conventional
deadlift styles.
Comparing
deadlifts with different grips, Beggs et al. (2011) compared the conventional
deadlift performed with a double overhand (pronated) or mixed (one hand pronated, one hand supinated) grip on latissimus dorsi
muscle activity
during sets with 60 and 80 % of 1RM load.
Comparing two different velocities
during an isokinetic machine
deadlift test, Noe et al. (1992) found no differences in latissimus dorsi
muscle activity between the two speeds used (45.7 vs. 30.5 cm / s).
Comparing two different velocities
during an isokinetic machine
deadlift test, Noe et al. (1992) found no differences in gluteus maximus

When controlling for relative load, bar speed does not affect erector spinae
muscle activity
during deadlifts.
