What is hamstring tendinopathy?

Hamstring tendinopathy, often referred to as hamstring tendinitis or hamstring tendonitis, is a condition in which the tendons of the hamstrings become overloaded and undergo degenerative changes. Unlike acute injuries such as muscle tears, hamstring tendinopathy usually develops due to repetitive strain, leading to irritation and weakness in the tendon tissue. The term hamstring tendinitis is sometimes used specifically for inflammation in the tendons, while hamstring tendinopathy is a broader category that also includes microtrauma and structural changes in the tendon.

This type of injury is common among athletes who perform activities that require speed and strength of the hamstrings, such as football players, sprinters, and dancers. Research shows that hamstring injuries are one of the most common injuries in athletics. (Opar et al., 2012). Hamstring tendonitis can have a major impact on an athlete's performance and well-being.

Recognition of hamstring tendinopathy and hamstring tendinitis

Symptoms of hamstring tendinopathy and hamstring tendinitis often develop slowly and can worsen if not treated in time. Some specific characteristics are:

1. Deep, persistent pain in the buttock area or back of the thigh, especially during activities such as running, prolonged sitting, or heavy exertion. This is typical for hamstring tendinopathy.

2. Pain when sitting for a long time: A study shows that the majority of people with hamstring tendinopathy experience pain while sitting (Petrzak et al., 2018). This symptom is characteristic of hamstring tendinopathy.

3. Increased pain after exertion: After training or prolonged strain, the pain often increases, which is a clear sign of tendon overload.

How does hamstring tendinopathy develop?

Hamstring tendinopathy and hamstring tendinitis usually arise from prolonged overuse of the tendons, where the tendons cannot recover quickly enough between training sessions. The peak force on the hamstring tendons during an intense sprint or jump can be considerable. This force, especially with repeated loading without sufficient recovery, can lead to microtears that, without proper treatment, can develop into chronic tendinopathy. (Chu et al., 2016). This emphasizes the importance of early recognition and treatment of hamstring tendinopathy.

Facts and figures about hamstring tendinopathy and hamstring tendinitis

Studies provide insight into the prevalence and risk factors of hamstring tendinopathy and hamstring tendinitis:

• Recurrence of injuries: Almost 30% of athletes recovering from a hamstring injury experience complaints again within the first year (Hallen et al., 2014). This emphasizes the importance of thorough rehabilitation with hamstring tendinopathy exercises.

• Risk factors: Differences in muscle strength and flexibility can increase the risk of hamstring injuries (Opar et al., 2012).

Treatment options for hamstring tendinopathy and hamstring tendinitis

For hamstring tendinopathy and hamstring tendinitis, treatment can range from traditional methods such as rest and ice to a targeted combination of training and eccentric loading. The goal is to strengthen the tendons sustainably and thus reduce pain.

Step 1: Rest and inflammation control

In the case of acute hamstring tendonitis symptoms, it is often advised to give the hamstrings a few days of rest and to use ice to reduce the inflammation. This can help to relieve hamstring tendonitis symptoms.

Step 2: Controlled load

Complete rest is often not the best solution. By applying controlled load, tendons can become stronger without causing new damage (Malliaras et al., 2013). Integrating hamstring tendinopathy exercises into the rehabilitation program is essential.

Step 3: Eccentric training

Eccentric exercises are increasingly recommended for hamstring tendinopathy. In this, the muscles are lengthened while delivering force, which promotes the rebuilding of the tendons. Eccentric training stimulates the recovery of hamstring tendinopathy and prevents a relapse. (Mjølsnes et al., 2004). This is an effective approach for hamstring tendinopathy.

The Nordic Hamstring Curl: The Most Important Exercise for Recovery

The Nordic Hamstring Curl (NHC) is one of the most effective hamstring tendinopathy exercises for hamstring tendinopathy and hamstring tendinitis. Research shows that eccentric exercises, such as the Nordic Hamstring Curl, effectively strengthen the hamstrings and reduce the risk of recurrence. In a study among football players, a significant decrease in hamstring injuries was observed, with more than 70% fewer injuries compared to control groups when applying the Nordic Hamstring Curl. (van der Horst et al., 2015).

How do you perform the Nordic Hamstring Curl?

1. Starting position: Kneel down, upright, while someone holds your ankles firmly or you place your feet under a sturdy object.

2. Movement: Lean forward slowly while keeping your back straight and lower your body. Use your hamstrings to slow down the movement. This is an effective exercise for hamstring tendinopathy.

3. Return movement: As soon as you can't go any further, let yourself lower to the ground in a controlled manner and push yourself back to the starting position.

The Nordic Hamstring Curl is particularly effective for the recovery of hamstring tendinopathy and hamstring tendinitis because it directly targets the muscles and tendons in the direction in which they are loaded. By performing this hamstring tendinopathy exercise regularly, you can strengthen the hamstrings and significantly reduce the risk of future injuries.

Preventive measures and additional exercises

In addition to the Nordic Hamstring Curl, other hamstring tendinopathy exercises and precautionary measures help with the recovery of hamstring tendinopathy:

• Eccentric leg curls: This exercise also targets the hamstrings and promotes gradual loading of the tendons. This is useful in hamstring tendonitis.

• Hip and trunk stability exercises: Strengthening the surrounding muscles can reduce the strain on the hamstrings.

• Progressive overload: By gradually increasing the intensity of the exercises, the hamstrings can be sustainably strengthened without overloading. This is crucial in the treatment of hamstring tendinopathy.

Extra tips for hamstring tendinopathy exercises

For those looking for effective hamstring tendinopathy exercises, it is important to focus on both strength and flexibility. Static stretching exercises can help improve muscle length, while dynamic exercises increase functional strength. Combining different types of exercises can contribute to a faster recovery from hamstring tendonitis and prevent future injuries.

Conclusion

Hamstring tendinopathy and hamstring tendinitis require a careful approach, focusing on rest, controlled loading, and eccentric hamstring tendinopathy exercises such as the Nordic Hamstring Curl. By practicing purposefully and consistently, not only can pain decrease, but also the risk of future hamstring injuries can be reduced. Supportive exercises such as hip stability and progressive loading help build sustainable strength and balance in the muscles. It is important to take hamstring tendonitis seriously and to start appropriate hamstring tendinopathy exercises in a timely manner.
