«hamstrings» - the semitendinosus muscle forms part of the hamstrings muscle group, along
with semimembranosus and biceps femoris.
The hamstring is actually a group of muscles called the semitendinosus,
semimembranosus and biceps femoris.
Pointing the toes inward (b) tends to emphasize the inner hamstrings (
semimembranosus and semitendinosus).
Seated leg curls will better target the inner side of the hamstrings, which includes the semitendinosus and
the semimembranosus, while the biceps femoris (traditionally called the thigh biceps) which has a somewhat different function from the previous two can be emphasized with lying leg curls.
The hamstring is actually comprised of three muscles: the semitendinosus,
semimembranosus and biceps femoris, which are responsible for knee flexion and stabilization and hip extension.
Lying leg curls with your hips on the bench will target the biceps femoris, while seated leg curls and lying leg curls with your hips off of the bench will emphasize the semitendinosus and
semimembranosus.
These are the biceps femoris (commonly known as the «thigh biceps»), semitendinosus and
semimembranosus, and they work together to bend your knees, help you jump high and run fast.
They are the semitendinosus,
semimembranosus and the biceps femoris, with the latter being the largest of them all.
Muscles producing joint actions at the knee joint are the quadriceps muscles (vastus medialis, vastus lateralis, vastus intermedius and rectus femoris at the front, with the hamstring muscles (semitendinosis,
semimembranosus and biceps femoris) at the back along with the popliteus muscle.
The semitendinosus and
the semimembranosus run down towards the tibia which is the bone on the inside of the lower leg; whereas, the biceps femoris runs down to the fibula, which is the bone on the outside of the lower leg.
I was very pleased with the strength gains I'd experienced, UNTIL the day I avulsed
my semimembranosus hamstring with 635.
The semimembranosus tendon would therefore have not avulsed and I would simply have stood there with the bar not moving (like has happened many times before in training when one gets «stuck»), until I decided enough was enough and set the bar down.
If they turn away from the midline of the body (lateral rotation), your biceps femoris is too strong for your semitendinosus and
semimembranosus.

The Hamstrings are a group of 3 muscles on the back of the thigh — biceps femoris, semitendinosus, and
semimembranosus.
In human anatomy, a hamstring is any of the three tendons contracted by three posterior thigh muscles (semitendinosus,
semimembranosus and biceps femoris), and the term is often also used to refer to the muscles themselves.
These are the quadriceps, which are located at the front of the thigh and consist of four separate muscles — the vastus lateralis, vastus medialis, vastus intermedius and rectus femoris; the hamstrings, which are located at the back of the thigh and consist of the biceps femoris, semitendinosus and
semimembranosus; and the calves, which consist of the large two - headed gastrocnemius muscle and the much smaller soleus muscle which lies underneath the gastrocnemius.
The major muscles used here are the hamstrings including
the semimembranosus, semitendinosis, and the two heads of the biceps femoris.
Those three muscles are the biceps femoris,
semimembranosus, and the semitendinosus.
Those muscles are the biceps femoris,
the semimembranosus, and the semitendinosus
There are three separate muscles that make up your hamstrings and they include the:
semimembranosus, semitendinosus, and biceps femoris, and they all work together when you are engaged in physical activities such as running, climbing stairs and jumping.
If I have a hamstring pull, for instance, is it in my biceps femoris or
semimembranosus that's pulled?
«hamstrings» -
the semimembranosus muscle forms part of the hamstrings muscle group, along with biceps femoris and semitendinosus.
Turning your toes out as you curl up will hit the outer area (semitendinosus and
semimembranosus) while angling your toes in as you curl up will hit the inner area (biceps femoris and adductors).
The Hamstring has three main muscles,
the semimembranosus, the semitendinosus and biceps femoris.
Whilst
the semimembranosus, the semitendinosus only cross one joint, the biceps femoris crosses two joints.
It has three other muscles which are called semitendinosus,
semimembranosus, and biceps femoris.
In addition, the combined semitendinosus and biceps femoris (long head) footprint on the ischial tuberosity is smaller in length (3.9 ± 0.4 vs. 4.5 ± 0.5 cm) and may also be smaller in height (1.4 ± 0.5 vs. 1.2 ± 0.3 cm) than
the semimembranosus footprint (Feucht et al. 2014).
There are four hamstrings muscles: the biceps femoris (long head), the biceps femoris (short head), the semitendinosus, and
the semimembranosus.
The hamstring is actually comprised of three muscles: the biceps femoris, the semitendinosus, and
the semimembranosus.
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).
Ono et al. (2010) found that EMG amplitude of the semitendinosus was significantly higher than that of
the semimembranosus during eccentric leg curls and Kubota et al. (2007) found that muscular soreness and signal intensity was greatest in the order semitendinosus > biceps femoris (long head) > semimembranosus following eccentric leg curls.
Ono et al. (2011) assessed hamstrings EMG amplitude during a stiff - legged deadlift and reported that the EMG amplitudes of the biceps femoris and of
the semimembranosus were significantly higher than that of the semitendinosus.
Dostal et al. (1986) reported that the moment arms were 5.6 cm for the semitendinosus, 4.6 cm for
the semimembranosus, and 5.4 cm for the biceps femoris (long head).
Dostal et al. (1986) reported that the moment arms were 0.5 cm for the semitendinosus, 0.3 cm for
the semimembranosus, and -0.6 cm for the biceps femoris (long head).
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).
The biceps femoris (long head), the semitendinosus, and
the semimembranosus are all bi-articular (two - joint) muscles.
When it does have a separate tendon, the proximal tendon of
the semimembranosus is located anteriorly and laterally to the shared tendon of the semitendinosus and biceps femoris (long head)(Miller et al. 2007; Philippon et al. 2014; Feucht et al. 2014).
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.
The semitendinosus and
the semimembranosus are located on the medial part of the thigh.
Additionally, some studies have found that
the semimembranosus also shares this same tendon (Neuschwander et al. 2015).
There are two major groups within the hamstrings: the medial hamstrings (semitendinosus and
semimembranosus) and the lateral hamstrings (biceps femoris short head and long head).
The medial group is made up of the semitendinosus and
the semimembranosus.
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).
