Have you ever felt a tightness or pain in the muscles on the back of your legs after sitting for days at a time, or when you suddenly go for a run or play sports? Sometimes this pain goes all the way to your back. Many people face this condition. The main reason for this is that the hamstring muscle group at the back of our thighs is weak or tight. So today we will talk about these hamstring muscles, especially the semitendinosus muscle in it, and what simple things we can do at home to keep them healthy.
What is Semitendinosus?
Simply put, the hamstrings are the muscle group that you can feel at the back of your thigh. They are actually a combination of three muscles: the semitendinosus, the semimembranosus, and the biceps femoris. The semitendinosus is the longest of these.
The main functions of this muscle group are:
- Helping you bend your knees.
- Helping to extend the thigh backwards (think of it like you're throwing your leg backwards to run).
- This also helps to rotate the main bone in your shin (tibia).
Now you understand how important these hamstring muscles are for the normal things we do, from walking to running and jumping.
Why is hamstring weakness dangerous?
We often think about the muscles in the front of our bodies (like the quadriceps in the front of our thighs), but we don't think about the muscles in the back. However, if these hamstring muscles are weak or too tight, a variety of problems can arise.
- Muscle Strain: A hamstring strain is a common injury for athletes. Imagine if you suddenly run fast while playing cricket, or if you suddenly kick the ball while playing football, a weak hamstring can easily become injured.
- Lower Back Pain: This is something that many people don't know. When your quadriceps muscles are strong and your hamstrings are weak, there is an imbalance in the muscles in your body. This can cause your posture to change, making it difficult to stand straight, and over time, there is a high chance of developing lower back pain . This is common among people who sit in a chair for long periods of time in the office.
- Poor Posture: Tight hamstrings make it difficult for you to stand and walk upright. It also affects your appearance.
The good news is that many of these problems can be avoided by strengthening and flexing these muscles with the right exercises and stretches.
Exercises that make hamstrings strong and flexible
The main goal of these exercises is to strengthen the hamstring muscles, reduce their tightness, and improve flexibility. These can be done at home, without any special equipment, using something like a chair or a towel.
| Exercise | How to do | Important points |
|---|---|---|
| Knee Flexion | 1. Stand behind a chair, hold the edge of the chair for balance, and shift your weight onto one leg. 2. Flex the foot of the other leg (turn the toes up), bend the knee, and slowly lift the leg behind you toward your buttocks. 3. Keep the front of your thighs straight. Don't sway your body from side to side. 4. Slowly bring the leg back to the ground. |
|
| Nordic Hamstring Curl | 1. Kneel on the floor. Place something like a towel under your knees for comfort. 2. Straighten your body so that there is one straight line from head to knees. 3. Place your heels under a bed or sofa. Or ask a friend to hold them. 4. Lean forward slowly, keeping your body straight, not your hips, but your knees. 5. Slowly return to the starting position until you feel a stretch in your hamstrings. |
|
| Supine Hamstring Stretch | 1. Lie faceup on the floor. Keep your legs straight. 2. Using a towel or strap, keep one leg straight and slowly pull it towards your head. 3. Do not rotate your hips to the side. Your legs should be straight and shoulder-width apart. 4. Hold for about 30 seconds, then slowly lower. Repeat 3-5 times. 5. Do the same for the other leg. |

Think about these things when exercising! (Safety First!)
No matter how good exercise is, it can cause injuries if not done properly. So keep these points in mind.
Start slowly.
It takes time to build strength. Not everything happens overnight. So start with light weights, with low repetitions. Little by little, week by week, you will feel your strength increase. Then slowly increase the weight or repetitions.
Warming up is essential.
Never start exercising all at once. Warm up your body by walking or jogging for 5-10 minutes. If you have stiff muscles in the morning, it is a good idea to walk or take a hot bath before exercising.
Listen to your body.
When stretching, stop when you feel a slight pull or pull in the muscle. If you feel sharp pain, it means you are doing too much. Never stretch beyond that point. It can damage the muscle. With daily practice, you will find that you can stretch further.
Remember, if your pain does not subside after these exercises, or if the pain gets worse, be sure to see your doctor for advice. You may need physiotherapy treatment.
Over time, if you do these simple things with discipline, you will see improvements in the strength of your hamstring muscles, flexibility, posture, and overall health.
Take-Home Message
- The hamstring muscles, located at the back of your thigh, are very important for walking, running, and maintaining proper posture.
- Weakening or tightening of these muscles can cause problems such as muscle strains and back pain.
- Many of these problems can be prevented with simple strengthening and stretching exercises that can be done at home.
- It is essential to warm up before starting any exercise, and never stretch your muscles to the point of pain.
- If the pain persists or worsens, do not self-treat and see your doctor.
