Very limited data exists
comparing biceps muscle activity during different horizontal pulling exercises.
Macdougall et al. (1984)
compared the biceps muscle cross-sectional area of untrained, intermediate and elite - level male bodybuilders.
Not exact matches
The most important reason for this phenomenon is the fact that the brachialis
muscle has more slow - twitch fibers than the
biceps, and therefore, has more of a stabilizing role
compared to the
biceps brachii which is meant for faster, more explosive work.
The upper arms, which include the
biceps and triceps, are quite small
compared to most other
muscle groups.
A
biceps curl can create more eccentric damage, more metabolite build - up, and greater sustained tension in the
biceps muscle than doing chin - ups — so can a triceps pushdown
compared to a weighted dip, or a forearm curl
compared to a heavy row.
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.
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.
Schantz et al. (1983)
compared the
muscle cross-sectional area between male and female students (aged 26 years) and reported much lower
biceps muscle cross-sectional area.
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.
Biceps brachii
muscle activity seems to be higher in the bench press using free - weights
compared to machine resistance.
Interestingly, the Nordic curl produces greater increases in
muscle fascicle length and preferential
biceps femoris (short head) and semitendinosus hypertrophy
compared to hip extension - based hamstrings exercises (Bourne et al. 2016).
From the limited literature, it is apparent that the
biceps femoris (long head) and the semimembranosus are the heaviest
muscles, while the
biceps femoris (short head) and semitendinosus are usually the lightest when
comparing within studies, although there are discrepancies (Wickiewicz et al. 1983; Ito et al. 2003; Horsman et al. 2007; Ward et al. 2009; Kellis et al. 2012).
