Question 1

Overview of the anatomy

Accepted Answer

Your hamstrings are three muscles at the back of your thigh. They support hip extension, knee flexion and powerful running movements. Targeted strength work can help develop their strength and capacity for running.

Question 2

What affects hamstring resilience?

Accepted Answer

Hamstring resilience depends on strength, training load, recovery and gradual exposure to faster running. A hamstring strain or tear can occur during sprinting or sudden movements. Progressive strength training and sensible load management may help reduce risk, but cannot guarantee injury prevention.

If it’s a very mild strain, you may be able to continue your activity, but at a slower pace. However, if it’s a more severe strain, you will likely have to walk slower and with very short strides.

The severity of the symptoms that you experience in the next few days will depend on how badly you’ve injured your hamstring – they can include:

Moderate to severe pain in the area of the tear. It is common for the rest of the muscle to feel tight and stiff, and it may be painful to sit on it.
It will likely be painful to walk or take long strides.
It will be painful to stretch your hamstrings, and in severe cases, you may be unable to fully straighten your knee for a few days.
Running will hurt.
It will be painful to contract your hamstring against resistance.
You may see some swelling and bruising, but this is not present in all cases. It may even take a few days to show. In addition, the bruise often shows up much lower than the tear because gravity pulls the fluid in the injured tissues downwards.

Question 3

When should you adjust training or seek advice?

Accepted Answer

Seek medical advice for sudden, severe, worsening or unusual symptoms, significant swelling, numbness, or difficulty with everyday movement. The app provides general training content and does not replace individual medical assessment.

Question 4

How can strength and mobility support running?

Accepted Answer

Build general running capacity with progressive strength work, mobility exercises and gradual changes to training load. Adapt sessions to your current ability and allow time for recovery. Seek medical advice for persistent, severe or worsening symptoms.

Question 5

How can I progress and manage training load?

Accepted Answer

Progress depends on your starting point, consistency, recovery and overall training load. Increase demand gradually rather than following a fixed timeline. If symptoms persist, worsen or include unusual signs, seek individual medical advice.
