Recognize and Treat Hamstring Pain: Causes and Solutions

“Nordbelt is easy to secure and feels stable.”

Cem — Trustpilot

Hamstring pain is a common problem that can affect not only athletes but also non-athletes. This pain ranges from mild discomfort to chronic, daily pain that can even make simple activities difficult. In this article, we discuss the causes of painful hamstrings, the symptoms and treatment options, and the preventive measures that can help reduce hamstring complaints.

Troubled by hamstring pain? The Nordbelt offers effective solutions to relieve your pain and strengthen your muscles.

What causes hamstring pain?

Is your hamstring painful? That can have various causes, including acute injuries and chronic conditions. Here are some of the main causes, supported by scientific research:

1. Overload

Intensive physical activities without sufficient rest can overload the hamstrings, leading to pain and muscle damage. Studies show that repeated strain without a recovery period can result in chronic pain and injuries in the hamstrings (Heiderscheit et al., 2010).

2. Muscle strain or tear

Sudden movements or overstretching of the hamstring can lead to muscle strains or tears. These acute injuries often cause severe pain and may require prolonged rehabilitation. Research shows that 22-34% of hamstring injuries in athletes are related to sudden, explosive movements, such as sprinting or jumping. (Clanton et al., 1998).

3. Chronic Hamstring Pain

Chronic hamstring pain often arises from persistent overuse or insufficient recovery after previous injuries. This type of pain can last for months and often requires a combined approach of physiotherapy and muscle strengthening exercises  (Pursalehian et al., 2023).

4. Hamstring Tendinopathy

Recognize and Treat Hamstring Pain: Causes and Solutions — training image 1

Inflammation or degeneration of the tendons that connect the hamstring to the pelvis or the knee can cause hamstring tendinopathy. This is common in athletes and results in pain around the tendon attachment. Treatment of tendinopathy often includes physiotherapy and exercise therapy to reduce the load on the tendons. (Pietrzak et al., 2018).

5. Nerve irritation

Back or hip problems can cause radiating pain in the hamstrings due to irritation of the sciatic nerve. Research shows that compression of the hip nerve or problems in the lower back can lead to radiating pain in the hamstring area, which is often confused with muscle pain. (Lam et al., 2020).

Symptoms of hamstring pain

The symptoms of a painful hamstring can vary depending on the cause, but the following symptoms are often recognizable:

Pain when sitting: Pain when sitting can be an indication of hamstring tendinopathy or irritation of the tendon attachment at the pelvis. This type of pain often occurs with overuse and tendon inflammation.

Pain at rest: Persistent pain at rest can indicate chronic inflammation or tendinopathy. Research suggests that rest pain is often associated with a long-term injury or chronic condition.

Pain in the back of the knee: Pain in the back of the knee can be a symptom of a hamstring strain or tendon problem. Studies show that this type of pain often indicates tension or damage to the lower attachments of the hamstring.

Aching pain: A constant, nagging pain in the hamstrings may indicate chronic overuse. Such pain is often related to previous, unhealed injuries or repetitive strain without rest.

Treatment options: What can you do for hamstring pain?

There are several treatment options that can help relieve hamstring pain and promote recovery. Choosing the right treatment method depends on the cause and severity of the pain.

Nordic Hamstring Curl

Preventive use of the Nordic Hamstring Curl is an effective method to prevent hamstring injuries and pain. This exercise significantly strengthens the hamstrings and helps to prevent injuries by strengthening weak hamstrings. Research shows that this exercise can reduce the risk of hamstring injuries by up to 51% (Brukner, 2015).

Rest and adjustment

Avoiding stressful activities. : Avoiding intensive activities helps the hamstrings recover and prevents further damage. This is especially effective for overuse complaints. (Mason et al., 2012).

Physiotherapy

1. Stretching exercises

Regular stretching exercises improve the flexibility of the hamstrings and help reduce tension in the muscles. Research shows that good flexibility is essential for preventing muscle strains and injuries [5,7].

2. Strengthening exercises

Strengthening exercises such as the Nordic Hamstring Curl have been proven effective in stabilizing the hamstrings and reducing the risk of future injuries. Studies show that the Nordic Hamstring Curl can help reduce hamstring injuries by up to 51% by improving muscle strength and stability. (van der Horst, 2015)

Try the Nordbelt for targeted strengthening exercises that effectively address hamstring pain.

Prevention of hamstring pain

Preventing painful hamstrings is possible with a few simple adjustments and exercises. Studies show that preventive measures can reduce the risk of hamstring injuries by 30-50% [4,7].

1. Regular stretching

Daily stretching exercises keep the hamstrings flexible and reduce the risk of injuries. This is essential for anyone who regularly participates in intensive physical activities. (Mason et al., 2012).

2. Gradual build-up of activity

Avoid abrupt increases in intensity in your training. By gradually building up the load, you can prevent overloading the hamstrings. (Petersen et al., 2011).

3. Good posture

Pay attention to your posture, especially while sitting. Good posture reduces the pressure on the hamstrings and can help prevent pain. (Mason et al., 2012).

4. Targeted hamstring training

Targeted exercises, such as the Nordic Hamstring Curl, are an effective preventive measure. Regular performance of this exercise can significantly reduce the risk of hamstring injuries by increasing muscle strength and stability. The Nordic Hamstring Curl is highly recommended for athletes and research shows it reduces the risk of hamstring injuries by 51%. (Brukner, 2015).

Invest in prevention: With the Nordbelt Can you effectively train your hamstrings at home and prevent hamstring pain.

When to seek medical help?

Although hamstring pain often improves on its own with rest and self-care, it may be wise to seek medical help for persistent complaints. Chronic pain, pain while sitting, or radiating pain in the back of the knee that does not improve may indicate a more serious underlying problem. Early medical intervention can help prevent further damage and complications.

Conclusion

Hamstring pain can range from mild discomfort to chronic pain that affects daily life. By recognizing the causes and symptoms in time and taking preventive measures, such as regular stretching, targeted strengthening exercises, and a gradual buildup of activity, you can significantly reduce the likelihood of hamstring pain. Research shows that a well-balanced prevention program can reduce the risk of hamstring injuries by 30-50%. Applying targeted eccentric exercises, such as the Nordic Hamstring Curl, is an effective step in preventing hamstring pain and injuries. Invest in your hamstring health for a pain-free and active lifestyle.

01 THE MOVEMENT

Watch. And see why
the Nordic curl works.

Hamstring load20%
  1. Phase 01Feet secured. Lean forward slowly from the knees.
  2. Phase 02Brake eccentrically — the muscle gets stronger as it lengthens.
  3. Phase 03Catch yourself with your hands, push back and repeat.

Eccentric training — producing force while the muscle lengthens — targets the moment when the hamstrings are loaded most during sprinting. The Nordic curl trains exactly that.

02 HOW IT WORKS

Secure. Click. Curl.

before you order?

Clear information upfront — no fine print hidden behind the buy button.

A personal question? contact@nordbelt.com We usually respond within 1 business day.
How do I use Nordbelt?

Choose a stable door, fitness bench, fence or beam. Close the buckle, adjust the length, check the attachment and start with controlled repetitions.

What is included in the package?

The Nordbelt, a compact storage bag, a practical guide and a progressive 10-week training protocol.

Do I need a training partner or bench?

No. Nordbelt is designed for independent training without a large Nordic bench. You do always need a firm, stable anchor point.

Is this suitable for recovery or rehabilitation?

Nordbelt can support controlled hamstring strengthening. During recovery, decide on timing, load and progression together with your doctor or physiotherapist.

What does shipping cost?

Shipping costs are calculated at checkout based on the destination and available carrier.

Can I return it?

You can request a return within 30 days of receipt. The product must be unused, clean and in its original packaging; return shipping costs are paid by the buyer.

Is Nordbelt suitable for beginners?

Yes. Start with a smaller range of motion and support if needed, keep repetitions controlled and follow the included 10-week protocol. Stop if your technique breaks down or you feel pain.

Which anchor points are safe?

Only use a solid door, heavy fitness bench, sturdy fence or fixed beam that cannot open, slide or tip. Before every set, pull firmly on the attachment in the same direction as the training load.

How often can I train Nordic Hamstring Curls?

There is no single frequency that suits everyone. Use the 10-week protocol as a progressive starting point and match volume and recovery time to your level, sporting load and technique.

Where does the 51% fewer hamstring injuries claim come from?

The 51% refers to programmes that included the Nordic Hamstring Exercise, not to Nordbelt as a product. A systematic review and meta-analysis of 8,459 athletes (van Dyk, Behan & Whiteley, Br J Sports Med, 2019) reported a reduction of up to 51%; individual results are not guaranteed.
