Location
Intense pain in
the back of the thigh.
Function
and Anatomy of Hamstrings
The hamstrings
cross two joints, the hip and the knee. They are comprised of
the semi-membranosus and semi-tendinosus muscles located on
the inner aspect at the back of the thigh. To the outside of
the rear aspect of the thigh we find the biceps femoris. Together
these three muscles make up what we commonly refer to as the
hamstrings.
It is important
to distinguish between a hamstring strain and sciatica as these
conditions are often confused. A hamstring strain usually occurs
in the centre of the thigh, unlike sciatica which will have
a point of origin at the outer side of the thigh. Sciatica often
produces pain in the hip, lower back and even down to the feet.
All this from one nerve being pinched! A simple test to distinguish
between the two is to lie on your back and raise one leg having
your knee straight, if this hurts it’s probably a hamstring
strain. Ask somebody to flex your foot, bending your foot towards
your knee. If this produces pain then it’s probably sciatica.
How
it affects your running
At first you may
have trouble running at your usual pace and may shorten your
running stride. As your hamstring deteriorates you will have
difficulty in extending your leg as this will produce intense
pain.
Causes of Hamstring
Strain
This injury is
usually the result of an over extension of the leg. This classic
scenario is that of running or sprinting downhill at speeds
that you are not accustomed to. Running on slopped roads and
banked surfaces can cause a hamstring strain as the muscle is
over stretched to keep a balanced running stride. Over pronation
(foot imbalance) can also lead to hamstring strain.
Treatment of Hamstring Strain
Initial treatment
should consist of an ice
pack. Some runners prefer to use a wet towel
that has been in the fridge. We recommend you use commercially
available ice packs for focused pain relief. Anti-inflammatory
such as Ibrobrufen will help to release the swelling. Please
note this should be taken with meals and never before running.
You can continue
running but it is essential that you modify your training routine.
Try to run on flat surfaces, shorten your stride and decrease
your speed until your injury has completely healed. The hamstring
stretch is an essential aspect of your treatment regime.
Hamstring Stretch
Sit with your injured
leg straight and your other leg bent. With your back straight
and your head up, slowly lean forward at your waist. You should
feel the stretch along the underside of your thigh. Hold the
stretch for 10 to 15 seconds. Repeat the stretch 6 to 8 times.
This stretching exercise may be helpful for patello-femoral
syndrome (pain under and around the kneecap), patellar tendinitis
(inflammation of the tendon that connects the patella and tibia)
and hamstring strain (overstretching or tearing of the muscles
on the back of the thigh).

Against the wall
Stand with you
feet shoulder width apart and bend over and put your hands on
your knees. Turn your feet slightly out to the sides and maintain
weight in your big toe and outside heel. With your hands externally
rotate your thighs and press out with your knees. Keep your
back straight and maintain the groove in your back. From this
position raise your butt up and back while rotating the pelvis
forward and maintaining a flat back without losing the groove.
You will feel the stretch in the hamstring group.

Recent sports studies
have suggested that “retro-running” can stretch
and strengthen the quadriceps and hamstrings to improve stability.
Retro-running is walking or running backwards. It is important
to start slowly with a slow walk and progress to a gentle jog.
Choose a smooth, flat road or you can utilize a treadmill with
handrails for support. Alternate your neck position to prevent
strains and limit your retro-running to two sessions per week
starting from 50 meters and progressing to 500 meters.
We also recommend
the use of sports
orthotics/ insoles to dramatically speed up
recovery time. Hamstring supports provide compression and stability
to the affected muscle to increase the healing phase of the
injury.
