They reported that
biceps muscle activity showed a trend towards superior muscle activity during the counter-movement bench press in the pre-sticking region, however the data did not reach statistical significance.
The descriptive statistics report that the inverted row (25 %) and the suspension trainer inverted row (22 - 28 %) produce similar
biceps muscle activity, while a lower angle of pull (the body oriented more horizontal) produced greater muscle activity (41 %) indicating that greater load produces greater
biceps muscle activity in this exercise.
The greatest
biceps muscle activity was reported in the dumbbell and incline curl displayed in the final 1/3 of the movement with the arm fully flexed.
Very limited data exists comparing
biceps muscle activity during different horizontal pulling exercises.
The one arm row (19 %) and ghost row (4 - 25 %) appear to produce similar levels of
biceps muscle activity but inferior to bilateral horizontal inverted rows (41 %).
Lehman et al. (2004) reported that loads equalling 10 to 12RM during pronated and supinated pull - downs produced similar
biceps muscle activity.
Single - joint exercises can be used to good effect to produce high levels of
biceps muscle activity.
Single - joint exercises can also be used to good effect to produce high levels of
biceps muscle activity.
Therefore, it appears that stable inverted rows performed with the body more horizontal produce the greatest
biceps muscle activity.
They report that despite similar absolute loads between medium and narrow grips, superior
biceps muscle activity was produced by the medium grip in the concentric portion only.
While
the biceps muscle activity was superior during the initial 1/3 of the movement when performing the preacher curl, muscle activity declined in both the 2/3 and 3/3 of the movement.
However, descriptive means of
the biceps muscle activity between the exercises was available.
Not exact matches
Therefore, the data appears to indicate that medium and narrow grip pronated and supinated pull - downs produce similar
muscle activity in the
biceps, while the chin - up appears to produce superior
muscle activity to the pull - up.
Oliveira et al. (2009) compared the
muscle activity during three types of
biceps dumbbell curl, including the standing curl, seated incline curl and the preacher curl.
Shoulder angle alters where exercises maximise
muscle activity, so using a variety of exercise with different points of peak contraction, such as standing curls and seated incline curls, may maximize
biceps hypertrophy.
They report the
muscle activity of the
biceps raged between 37 to 43 % of MVC, with no difference in the overall
muscle activity between conditions.
They report that inverted rows performed from a barbell (77 %) produced statistically superior
muscle activity in the
biceps compared with the suspension trainer (67 %) variation.
However, comparing the exercises showed that the
biceps displayed 17.9 % greater
muscle activity during the chin - up (96 % MVC) compared with the pull - up (78 %) exercise.
They reported that the
biceps brachii displayed significantly greater
muscle activity when performing the free - weight bench press compared to the smith machine at 60 % but not 80 % of 1RM.
Assessing the effect of weight implement used, Saeterbekken et al. (2011) explored the differences in
biceps brachii
muscle activity between the free - weight barbell, dumbbell and smith machine bench press.
They reported that the
biceps brachii displayed significantly greater
muscle activity during the dumbbell bench press, while the barbell bench press displayed significantly greater
activity than the smith machine.
Biceps brachii
muscle activity seems to be higher in the bench press using free - weights compared to machine resistance.
Assessing the effect of load, McCaw & Friday (1994) found a main difference in
biceps brachii
muscle activity between 60 % and 80 % of 1RM when performing the free - weight and smith machine bench press.
