it is composed of «bicep femoris or long head», «semibranosus», «bicep femoris or short head», and «semitendinosus ``.
Since the moment arm lengths for hip extension appear to be similar between the semitendinosus, semimembranosus and biceps femoris (long head)(Dostal et al. 1986), this may imply that one muscle in each subgroup is better suited for producing large excursions with high joint angular velocities while the other may be better suited for performing very forceful muscular contractions over short excursions (see review by Lieber and Fridén, 2000).
There are four hamstrings muscles: the biceps femoris (long head), the biceps femoris (short head), the semitendinosus, and the semimembranosus.
Bourne et al. (2015) found that the Nordic hamstring curl produced preferentially higher semitendinosus EMG amplitude; but again, Zebis et al. (2013) did not report any preferential activation; Mendiguchia et al. (2013a) reported preferential biceps (short head) activation; and Ditroilo et al. (2013) reported that biceps femoris EMG amplitude exceeded maximum voluntary eccentric contraction levels by some margin.
From the limited literature, it is generally apparent that the biceps femoris (long head) and the semimembranosus have the greatest muscle cross-sectional area, while the biceps femoris (short head) and semitendinosus generally have the smallest muscle cross-sectional area (Pohtilla et al. 1969; Ito et al. 2003; Woodley and Mercer, 2005).
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).
Similarly, the biceps femoris (long head) is usually found to be greater in size than the biceps femoris (short head).
They are usually divided into two groups, the lateral hamstrings (biceps femoris long and short heads) and the medial hamstrings (semitendinosus and the semimembranosus) on the basis of their locations on the rear part of the thigh.
Along with the biceps femoris (short head), this forms the lateral group of the hamstrings musculature.
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).
From the limited literature, it is generally apparent that the biceps femoris (long head) and the semimembranosus have the greatest muscle volume, while the biceps femoris (short head) and semitendinosus generally have the smallest muscle volume (Friederich and Brand, 1990; Miokovic et al. 2011; Nakase et al. 2013).
The four hamstrings muscles are: the biceps femoris (long head), the biceps femoris (short head), the semitendinosus, and the semimembranosus.
The weight of the biceps femoris (long head) has been recorded at between 55.8 — 245.0 g, the weight of the semimembranosus has been recorded at between 109.3 — 146.0 g, the weight of the biceps femoris (short head) has been recorded at between 57.1 — 114.0 g, and the weight of the semitendinosus has been measured at between 84.7 — 220g (Wickiewicz et al. 1983; Ito et al. 2003; Horsman et al. 2007; Ward et al. 2009; Kellis et al. 2012).
